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.

Jul 01, 2013 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. Accessing cloudLibrary digital library collection has never been easier, find your library, choose your apps, access digital content - learn how it works on mobile, desktop, amazon, widnows, android ios, mac,chrome. Access Library Folder On Mac. The Library Folder on your Mac contains Preference Files, Caches, and Application Support Data. While regular Mac users may not find the need to access the Hidden Library Folder, advanced Mac users will at times come across the need to access files inside the Library Folder for troubleshooting and other purposes.

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:

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:

Access System Library Mac

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.

Once your framework is ready to go, you need to decide where to install it. Where you install a framework also helps determine how to install the framework.

Locations for Public Frameworks

Third-party frameworks can go in a number of different file-system locations, depending on certain factors.

Most public frameworks should be installed at the local level in /Library/Frameworks.
If your framework should only be used by a single user, you can install it in the ~/Library/Frameworks subdirectory of the current user; however, this option should be avoided if possible.
If they are to be used across a local area network, they can be installed in /Network/Library/Frameworks; however, this option should be avoided if possible.

For nearly all cases, installing your frameworks in /Library/Frameworks is the best choice. Frameworks in this location are discovered automatically by the compiler at compile time and the dynamic linker at runtime. Applications that link to frameworks in other directories, such as ~/Library/Frameworks or /Network/Library/Frameworks, must specify the exact path to the framework at build time so that the dynamic linker can find it. If the path changes (as it might for a user home directory), the dynamic linker may be unable to find the framework.

Another reason to avoid installing frameworks in ~/Library/Frameworks or /Network/Library/Frameworks is the potential performance penalties. Frameworks installed in network directories or in network-based user home directories can cause significant delays in compilation times. Loading the framework across the network can also slow down the launch of the target application.

Third-party frameworks should never be installed in the /System/Library/Frameworks directory. Access to this directory is restricted and is reserved for Apple-provided frameworks only.

How To Install C++ Program

When you build an application or other executable, the compiler looks for frameworks in/System/Library/Frameworks as well as any other location specified to the compiler. The compiler writes path information for any required frameworks in the executable file itself, along with version information for each framework. When the application is run, the dynamic link editor tries to find a suitable version of each framework using the paths in the executable file. If it cannot find a suitable framework in the specified location (perhaps because it was moved or deleted), it looks for frameworks in the following locations, in this order:

The explicit path to the framework that was specified at link time.
The /Library/Frameworks directory.
The /System/Library/Frameworks directory.

If the dynamic link editor cannot locate a required framework, it generates a link edit error, which terminates the application.

Locations for Private Frameworks

Custom frameworks intended for internal use should be installed inside the application that uses them. Frameworks embedded in an application are stored in the Frameworks directory of the application bundle. The advantage of embedding frameworks in this manner is that it guarantees the application always has the correct version of the framework to run against. See Embedding a Private Framework in Your Application Bundle for information on how to embed a custom framework in your application.

The limitation of embedding frameworks is that you cannot share the framework among a suite of applications. If your company develops a suite of applications that rely on the same framework, you might want to install one copy of that framework that all of the applications can share. In such a situation, you should install the frameworks in the /Library/Frameworks directory and make sure the frameworks bundle does not contain any public header information.

Installing Frameworks

How you install frameworks depends on your framework. If your framework is bundled inside of a particular application, there is nothing special you need to do. The user can drag the application bundle to a local system and use the application without any need for additional installation steps.

If your framework is external to an application, you should use an installation package to make sure it is put in the proper location. You should also use an installation package in situations where an older version of your framework might be in place. In that case, you might want to write some scripts to update an existing framework bundle rather than replace it entirely. For example, you may want to install a new major version of your framework without disturbing any other versions. Similarly, if you have multiple applications that rely on the same framework, your installation package should check for the existence of the framework and install it only as needed.
