`pkg-config'
command (see http://pkgconfig.freedesktop.org/), wheres the second one uses `rmol-config'
script. These methods are shortly described below.`pkg-config'
is a helper tool used when compiling applications and libraries. It helps you insert the correct compiler and linker options. The syntax of the `pkg-config'
is as follows:
% pkg-config <options> <library_name>
For instance, assuming that you need to compile an RMOL based program `my_prog.cpp'
, you should use the following command:
% g++ `pkg-config --cflags rmol` -o my_prog my_prog.cpp `pkg-config --libs rmol`
For more information see the `pkg-config'
man pages.
`rmol-config`
, which is installed by default in `$prefix/bin'
(`/usr/local/bin'
) directory. It can be used to simplify compilation and linking of RMOL based programs. The usage of this script is quite similar to the usage of the `pkg-config'
command.
Assuming that you need to compile the program `my_prog.cpp'
you can now do that with the following command:
% g++ `rmol-config --cflags` -o my_prog my_prog.cpp `rmol-config --libs`
A list of `rmol-config'
options can be obtained by typing:
% rmol-config --help
If the `rmol-config'
command is not found by your shell, you should add its location `$prefix/bin'
to the PATH environment variable, e.g.:
% export PATH=/usr/local/bin:$PATH
`LD_LIBRARY_PATH'
environment variable might be used to inform the linker of the dynamic library location, e.g.: export LD_LIBRARY_PATH=<RMOL installation prefix>/lib:$LD_LIBRARY_PATH
