You can download the precompiled binaries here and skip to the next section, however such a version may be not optimized for your machine.

Conversely, if you want a version of GURLS++ and bGURLS++ optimized for your machine, follow the steps described in the rest of the section.

GURLS++ and bGURLS++ are part of the same project, called gurls. Users may choose what libraries will be built during project configuration (See section Configuring GURLS++/bGURLS++ for details).In the following we assume that the directory where 'gurls++' and 'bgurls++' directories reside is named GURLSROOT.

Installing GURLS++/bGURLS++ on Linux

Below we describe how to build and install GURLS++ on Ubuntu (tested on Ubuntu 12.04). For other distributions, the same packages must be installed with the distribution-specific method.

1. Install the cmake build system (www.cmake.org/)

2. To link against some Blas and Lapack implementations you may need a fortran compiler e.g. for gfortran:

If your workflow involves working with InDesign libraries (.indl) files stored on a network or in a shared location, InDesign crashes on launch. The Library folder is hidden by default. To open the Library folder, click the desktop to make sure you are in the Finder, hold down the Option key, then. Mar 10, 2019 While there are options to keep your Mac from running out of space, like optimizing your photo storage if you use iCloud Photo Library, it comes at a cost: Without a fully-stored Photos library, you won't be able to create secondary backups of your images and video. (And as good as iCloud has become, your photos and video are precious enough. Jul 01, 2013 Depending on the choice you make, CMake will try to find the libraries in standard locations in the system. Normally this process should run fine, however, in case the libraries have been installed in some non-standard directory, you may have to manually specify their location. Where are the photos I imported into Photos on my Mac? By default, the photos and videos you import into Photos are stored in the Photos library in the Pictures folder on your Mac. When you first use Photos, you create a new library or select the library that you want to use. This library automatically becomes your System Photo Library. AppleScript Libraries are installed and made available for use by AppleScript scripts, by placing their files within a folder titled: “Script Libraries”. A Script Libraries folder can reside in a variety of locations, depending on how you want to define their availability on the computer.

3. Create a build directory (e.g. 'build') for GURLS++

4. Run cmake into the build directory

The last command will show the CMake interface, which must be used to set the values of some variables used for building and installing GURLS++. See the section Configuring GURLS++/bGURLS++ below for more information on these variables and how to set them to appropriate values.

5. Start building

6. Install the library(ies) to the path defined at configuration time

The command wil also install to the same path all the dependencies that user chose tobuild automatically.

Installing GURLS++/bGURLS++ on Windows

Below we describe how to build and install GURLS++ on Windows with Visual Studio (tested with VS Express 2010 and VS Express 2008).

Install the CMake build system downloading the installer from http://cmake.org/cmake/resources/software.html.
Install your favourite Blas/Lapack implementation. Under Windows AMD’s ACML is probably the easiest choice, since they provide the library binaries for free, however it supports only compilers with 64 bits.
Create a build directory (e.g. $GURLSROOT/build).
Run the CMake GUI. You will have to set the source directory to $GURLSROOT directory, and the build directory to the directory created at the previous step. After pressing the configure button, you will have to chose the generator for the project (e.g. Visual Studio 10). On Windows you may encounter the error message 'error in conﬁguration process, project files may be invalid', check that the you have writing rights to the path specified in the variable CMAKE_INSTALL_PREFIX. If this is not the case, change such a variable to a folder to which you have writing rights and press 'configure'. Now you have to set the values of some variables used for building and installing the libraries according to your preferences. See the section Configuring GURLS++/bGURLS++ below for more information on these variables and how to set them to appropriate values. After having configured the build options, press the generate button to create the solution file.
Open the generated solution under Visual Studio and build it.
Optional: install GURLS++ by explicitely building the install project included in the solution (it is not automatically built when building the solution).

Configuring GURLS++/bGURLS++

The configuration step is carried out using CMake.In the following we describe the configuration process using the GUI of CMake, e.g. under Windows or Mac.A similar process shall be followed when using the command-line interface.

Press 'configure', and CMake will try to determine the correct values for all variables. After the first configuration a list of variables is displayed. The following variables should be checked:

CMAKE_INSTALL_PREFIX The path where the library will be installed to;
GURLS_BUILD_GURLSPP (ON): Build GURLS++.If set to ON CMake also evaluates the variables
- GURLSPP_BUILD_DEMO (ON): Enable the building of the GURLS++demo programs;
- GURLSPP_BUILD_DOC (OFF): Enable the building of the GURLS++documentation using doxygen;
GURLS_BUILD_BGURLSPP (ON): Build bGURLS++. If set to ON CMake also evaluates the variables
- BGURLSPP_BUILD_DEMO (OFF): Enable the building of the BGURLS++demo programs;
- BGURLSPP_BUILD_DOC (OFF): Enable the building of the BGURLS++documentation using doxygen;
GURLS_USE_BINARY_ARCHIVES (ON): If set to ON, all data structures are stored in binary (rather than text) files, saving storage space and time;
GURLS_USE_EXTERNALS (ON): Enable automatic building of external dependencies.

If set to ON CMake also evaluates the variables

- GURLS_USE_EXTERNAL_BLAS_LAPACK (ON): Enable automatic building of blas and lapack, using OpenBLAS (LINUX-ONLY).

- GURLS_USE_EXTERNAL_BOOST (ON): Enable automatic building of boost. If set to OFF, press 'advanced' to visualize the variables related to the BOOST library, typically you have to specify only the variable BOOST_INCLUDE_DIR;

- GURLS_USE_EXTERNAL_HDF5 (OFF): Enable automatic building of libHDF5 and its dependencies(MPICH and zlib). Used only if GURLS_BUILD_BGURLSPP is set to ON.

For each variable which is set to OFF, you must specify the path to the corresponding library.

If GURLS_USE_EXTERNALS is set to OFF you have to manually specify the path to all of the above libraries.

3. If CMake does not find some required library, an error message will be displayed. Change the path to required library and press 'configure' again.

4. In the main screen you may change a number of variables. Most of them can be left unchanged, but some must be set to appropriate values. The following are the variables whose values should be checked:

BLAS_LAPACK_IMPLEMENTATION. Allows user to specify an implementation of the Blas/Lapack routines. Available choices are: ACML, ATLAS, MKL, NETLIB, OPENBLAS (under linux). Depending on the choice you make, CMake will try to find the libraries in standard locations in the system. Normally this process should run fine, however, in case the libraries have been installed in some non-standard directory, you may have to manually specify their location.

5. Once all variables have been set, press 'configure' again, and CMake will check the settings. As in step (3), if something is wrong an error message will be displayed and you will have to go back to the main screen to tweak the configuration.

6. When the settings are correct, the option ’generate’ will appear. Press 'generate'. CMake will generate the files and exit.

After the build files (e.g. the Makefile under Linux) have been generated, you can proceed as explained above.

Apple's photo management software for the Mac, Photos, has grown to be a fairly competent all-purpose storage locker. But as your photo and video library grows — and especially if you've taken advantage of iCloud Photo Library — you may find that your Photos library strains to fit on your Mac's hard drive.

While there are options to keep your Mac from running out of space, like optimizing your photo storage if you use iCloud Photo Library, it comes at a cost: Without a fully-stored Photos library, you won't be able to create secondary backups of your images and video. (And as good as iCloud has become, your photos and video are precious enough that they're worth keeping backed up in multiple places.)

There is an alternative: Moving your Photos library to an external drive (or creating an entirely separate library and syncing it with iCloud). Here's how to do it, and some reasons why you should — and shouldn't! — consider it for your needs.

Why you should (and shouldn't) use an external drive with Photos for Mac

There are a number of reasons why an external drive might make sense when you're working with Photos for Mac:

You have a giant Photos library (and, if you use iCloud Photo Library, you want to ensure you have a secondary backup of everything in that library)
You frequently swap computers and want to work on your images from any Mac
Your library isn't huge, but you'd prefer to save space on your Mac for other files
You share a computer with other users and you have limited drive space
If you're working with space constraints on your primary computer, it's one of the easiest ways to back up your full iCloud Photo Library

That said, there are some downsides, too. Here are some reasons you might not want to use an external drive:

You don't have a big enough library to warrant moving it off your Mac
You don't want to have to worry about always having your external drive connected to view and edit your images
You use a laptop frequently and can't afford an SSD, and you don't want to risk breaking your disc-based hard drive by constantly moving it
You don't want to accidentally create duplicate libraries that can't be connected to iCloud Photo Library (because your offsite library is connected)
Unless you purchase a speedy drive, working externally is almost always slower than working on your default hard drive
You don't want to spend the money on an external drive
If you use an automated backup service for your computer, you'll have to set up a second set of rules for backing up your hard drive

Best external drives for storing photos

Okay, so you've decided to move your Photos library over to an external drive. What next? If you already have an external drive, you can always use it for storing your Photos library (and save on cash). But if you're considering getting a new drive for this endeavor, here's what I suggest:

Get a drive that's at least 1-2TB in space, preferably 4TB. With the iPhone able to save 4K video, our space needs aren't shrinking anytime soon: The bigger hard drive you can afford, the better.
If you're buying a stationary hard drive, buying a disc-based hard drive is great, but buy good brands — don't try and save $50 on an off-brand hard drive. It's rarely worth the HDD failure.
If you're buying a portable hard drive, consider SSD: It's very pricey in comparison to a disc-based drive, but if you know you'll be frequently moving around — especially if you plan to move around with the drive connected — you want a drive that can take a little rumble and tumble without skipping or failing.
Hard drive speeds are important, too: The faster a drive's write speed, the quicker your images will copy; the faster a drive's read speed, the easier it will be for you to view images or video and edit them, too.

Want some recommendations for specific external hard drives? We've got those, too.

How to move your current Photos library to an external drive and use it as your primary library

As with creating a new library, moving your library to your external drive is a multi-step process. Here's how to go about it.

Step 1: Copy over your Photos library

Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.
Open a new Finder window.
Open your external drive in that window.
Open a new Finder window. Don't close your previous window (open to your external drive), as you'll need it shortly.
Click the Go menu and navigate to your Home folder.
Select the Pictures folder.
Select your old library.
Drag it to your external drive in the other Finder window.

Your library will begin to copy over to your external drive. Depending on the size of your library and speed of your drive, this can take anywhere from a few minutes to several hours, so be patient. Don't unplug your drive or turn off your computer during this process.

Step 2 (if you use iCloud): Turn off iCloud sync on your old library

Before you open your copied Photos library on the external drive, you have to disassociate the library on your Mac from iCloud. (If you don't use iCloud Photo Library, you can skip these steps.)

Open Photos on your Mac.
Go to the Photos menu.
Select Preferences.
Click on the iCloud tab.
Uncheck iCloud Photo Library.
Press Remove from Mac to remove any undownloaded low-resolution items from this library.
Quit Photos.

Step 3: Make your new library your system default

Now, it's time to make your newly-copied Photos library your system default.

Open Photos on your Mac.
Go to the Photos menu.
Select Preferences.
Click Use as System Photo Library.

Step 4 (if you use iCloud): Connect your new library to iCloud

Your external library is now set up to be your system default, but it's not currently connected to iCloud. If you use iCloud Photo Library and want to keep that connection active so that you can continually download items you've stored, read on. (Otherwise, you can skip this step.)

Open Photos on your Mac.
Go to the Photos menu.
Select Preferences.
Click on the iCloud tab.
Check iCloud Photo Library.
Click Download Originals to this Mac.
Wait for your Mac to download your images from iCloud. (Depending on the size of your iCloud library and your internet connection, this may take up to 24 hours; don't disconnect your external drive or turn off your Mac during this time.)

Once your library has fully synced and downloaded images, you can disconnect your drive; whenever you want to use your Photos library, you now need to connect your drive to your Mac.

Step 5: Get rid of your old library

A personal plea: Please, please, please make sure your library is fully copied and working on your external drive before you follow the steps below — once you've thrown away your original library, it's gone!

Open a new Finder window.
Click the Go menu and navigate to your Home folder.
Select the Pictures folder.
Select your old library.
Drag it to the Trash (or press Command-Delete on your keyboard).
Empty the Trash.
Open a new Finder window. Don't close your previous window (open to the Pictures folder), as you'll need it later.
Select your external drive.
Right-click (or control-click) on your copied Photos library on your external drive.
Select Make Alias.
Drag the alias to the Pictures folder.
Rename the alias to remove the 'alias' part of its name.

Now you have a direct link to your copied Photos library from the Pictures folder: This prevents your computer from accidentally creating multiple Photos libraries in case you forget to launch Photos with your external drive connected.

Note: If you're worried about accidentally creating libraries, you can always launch Photos by option-clicking on its icon in the Dock or Applications folder; this will give you the option of picking which library you'd like to launch.

How to create a new Photos library on your external drive and use it as your primary library

Creating a new library on your external drive is a multi-step process. Here's how to go about it.

Step 1 (if you use iCloud): Turn off iCloud sync on your old library

Before you create a new Photos library, you have to disassociate your current library as your system default. (If you don't use iCloud Photo Library, you can skip these steps.)

Open Photos on your Mac.
Go to the Photos menu.
Select Preferences.
Click on the iCloud tab.
Uncheck iCloud Photo Library.
Press Remove from Mac to remove all low-resolution items from this library.
Press Remove from Mac once more to confirm.
Quit Photos.

Step 2: Create your new Photos library

Once you've done this, it's time to create a new library.

Connect an external drive to your Mac via USB, USB-C, or Thunderbolt.
Option-click (and continue holding down option) when launching the Photos app on your Mac.
When it asks you to choose a library, click on Create New….
Name your library.
Press the Down arrow to expand the File picker and choose your external drive as the new location.
Press OK to save it to your external drive.

Step 3: Make your new library your system default

You'll now have an empty library on your external drive. Next up: Making it your system library.

Open Photos on your Mac.
Go to the Photos menu.
Select Preferences.
Click Use as System Photo Library.

Step 4 (if you use iCloud): Connect your new library to iCloud

Your external library has now been set up from scratch. If you use iCloud Photo Library and want to download all the items you've stored there to have an external backup, read on. (Otherwise, you can skip this step.)

Open Photos on your Mac.
Go to the Photos menu.
Select Preferences.
Click on the iCloud tab.
Check iCloud Photo Library.
Click Download Originals to this Mac.
Wait for your Mac to download your images from iCloud. (Depending on the size of your library and your internet connection, this may take up to 24 hours; don't disconnect your external drive or turn off your Mac during this time.)

Once your library has fully synced and downloaded images, you can disconnect your drive; whenever you want to use your Photos library, you now need to connect your drive to your Mac.

Step 5: Get rid of your old library

A personal plea: Please, please, please make sure your new library is live and working on your external drive before you follow the steps below — once you've thrown away your original library, it's gone!

Open a new Finder window.
Click the Go menu and navigate to your Home folder.
Select the Pictures folder.
Select your old library.
Drag it to the Trash (or press Command-Delete on your keyboard).
Empty the Trash.
Open a new Finder window. Don't close your previous window (open to the Pictures folder), as you'll need it later.
Select your external drive.
Right-click (or control-click) on your new Photos library.
Select Make Alias.
Drag the alias to the Pictures folder.
Rename the alias to remove the 'alias' part of its name.

Now you have a direct link to your Photos library from the Pictures folder: This prevents your computer from accidentally creating multiple Photos libraries in case you forget to launch Photos with your external drive connected.
