libSUFR is a LIBrary of Some Useful Fortran Routines that I wrote for my own use, but that may also be useful for others. It currently also “SUFRs” from the fact that Fortran module files are compiler dependent… To download the libSUFR package, read the code documentation, or to contact the developer, see: https://libsufr.sourceforge.net/
libSUFR is written in Fortran, hence you will need a Fortran compiler. Gfortran, part of gcc, is a free, open-source Fortran compiler included in many GNU/Linux distributions and available from https://gcc.gnu.org/fortran/.
The default installer uses CMake to configure and compile the code. CMake is also open-source software, also included in most GNU/Linux distributions, and can be downloaded from https://www.cmake.org/. Alternatively, you can create your own Makefile or compile and link the code manually.
After downloading from libsufr.sf.net, you can unpack the tarball and cd into its directory by doing e.g.:
$ tar xfz libsufr-0.0.1.tar.gz $ cd libsufr-0.0.1/
(replace “0.0.1” with the correct version number).
To configure, compile and install the code (into CMake’s default system directories usr/local…), from the main package directory (the one that contains the file CMakeLists.txt), do:
mkdir build && cd build/
cmake ..
make
sudo make installThe second step above configures the code and should find your Fortran compiler. The third step compiles and links the code, and the last step installs it on your system - for which you need root priveliges, hence the ‘sudo’ command.
To install the package in a specific system directory, e.g. the Linux default /usr/... (recommended), do:
mkdir build && cd build/
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr ..
make
sudo make installTo install the package in your own user directory, you don’t need root priveliges, can omit the ‘sudo’ command and combine the last two commands, e.g.:
mkdir build && cd build/
cmake -DCMAKE_INSTALL_PREFIX:PATH=/home/me/usr ..
make installTo compile the code with your favourite compiler (in case you have several installed), prepend the cmake line with e.g. FC=gfortran:
FC=gfortran cmake ..If you have multiple cores or processors, you can speed up the make step by specifying the number of parallel build jobs using the -j option. E.g., for four cores, you can have four parallel jobs and use:
make -j4To compile the code without installing it anywhere, leave out the install step
mkdir build && cd build/
cmake ..
makeThe compiled libraries and modules can then be found in the usr/ subdirectory of the package dir.
On a Linux system, the library and module files could be installed as:
/usr/lib/libSUFR.* /usr/include/libSUFR/*.mod
If you want to use the libraries with multiple Fortran compilers, you will want to keep the different versions of the library separated. In this case, use (in addition to any other options):
cmake -DCOMPILER_SPECIFIC_LIBS=on ..The library files will then be installed as:
/usr/lib/libSUFR_<NameOfFortranCompiler>.* /usr/include/libSUFR/<NameOfFortranCompiler>/*.mod
If one of your Fortran compilers is your default, you can use both the default installation method and the compiler-specific method to install the library for both compilers on the same system.
