First download the latest CGP-Library from Download and unzip the file.
The simplest method of using the CGP-Library is to include cgp.c and cgp.h in your build path and compile them along with your own files. For instance #include “cgp.h” in your own program and then compile your program similar to
$ gcc yourFiles.c cgp.c cgp.h
On windows operating systems the macro NO_DLL must also be #defined at compile time
$ gcc yourFiles.c cgp.c cgp.h -D NO_DLL
If you intend to make us of the support for multiple threads you must also set the openMP compiler flag
$ gcc yourFiles.c cgp.c cgp.h -fopenmp
The standard method of using dynamic libraries is to link against the compiled library.
To compile the shared object (.so) open a terminal in the CGP-Library directory and run
$ make so
Then copy the generated libcgp.so to /usr/lib by running
$ sudo cp libcgp.so /usr/lib
Give libcgp.so the necessary permissions by running
$ sudo chmod 0755 /usr/lib/libcgp.so
Now copy cgp.h to /usr/include by running
$ sudo cp src/cgp.h /usr/include/
Now update the system so it knows about libcgp.so
$ sudo ldconfig
Finally check that CGP-Library has been installed
ldconfig -p | grep libcgp
Once CGP-Library has been installed it can be used by #include <cgp.h> in your project and linking against the libcgp.so using the -lcgp compiler flag. Similar to
$ gcc yourFiles.c -lcgp
For windows the CGP-Library has been pre-compiled into CGP-Library.dll. In order to use CGP-Library.dll there are two options 1) place CGP-Library.dll in the same directory as any executables which use the CGP-Library, or 2) place CGP-Library.dll in the standard windows location for dynamic-link library i.e. C:\Windows\System32 for 32bit or C:\Windows\SysWOW64 for 64bit. Then #include “cgp.h” when compiling any programs which use the CGP-Library.
