MFrontmfront handles the compilation of shared libraries. More precisely, the compilation phase is delegated to external tools called generators in the mfront wording. mfront currently supports two generators: make and cmake.
In both cases, the compilation process can be affected by defining any of the following optional environment variables:
TFELHOME: this variable must contain the path where mfront is installed. This variable is used by tfel-config to return the path to the header files and libraries delivered by the TFEL project. This variable thus affects the output of the following commands (see tfel-config --help for details):
tfel-config --includes and tfel-config --include-pathtfel-config --libs and tfel-config --library-pathCXX: this variable defines the C++ compiler to be used. Note that this choice must be consistent with the compiler used to compile mfront if the compiler flags defined by default by `mfront are used (see below).
CXXFLAGS: this variable defines the compiler flags to be used. If this variable is not defined, mfront will use the following outputs of tfel-config (see tfel-config --help for details): tfel-config --warnings --compiler-flags --cppflags --cxx-standard
LDFLAGS: this variable defines flags passed to the linker.
Those compiler flags are completed by the following outputs of tfel-config depending on the level of optimisation requested by the user using the --obuild command line option of mfront:
--obuild=level0: tfel-config --oflags0--obuild=level1 (or simply --obuild): tfel-config --oflags--obuild=level2: tfel-config --oflags --oflags2If the -g command line option is passed to mfront, those flags are completed by the following output of tfel-config: tfel-config --debug-flags.
