acinclude (9rheolef)

These macros test for particular system featutres that rheolef uses. These tests print the messages telling the user which feature they are looking for and what they find. They cache their results for future configure runs. Some of these macros set some shell variable, defines some output variables for the `config.h' header, or performs Makefile macros subsitutions. See autoconf documentation for how to use such variables.

Follows a list of particular check required for a successfull installation.

RHEO_RECOGNIZE_CXX

Check wheter we are able to recognize the C++ compiler. Tested compilers:

         The GNU   C++ compiler that defines: __GNUC__  (egcs-1.1.1)
         The INTEL C++ compiler that defines: __ICC     (ICPC-12)

If so, substitue RECOGNIZED_CXX to a specific compiler's rule file, e.g, {}"$top_srcdir/config/gnu_cxx.mk", for a subsequent Makefile include. If not, substitue to "/dev/null". Substitutes also EXTRA_LDFLAGS. Raw cc is the C compiler associated to the C++ one. By this way C and C++ files are handled with a .c suffix. Special C files that requiere the cc compiler, such as "alloca.c" use some specific makefile rule.

usage example:

    AC_PROG_CC(gcc cc icc cl)
    AC_PROG_CXX(c++ g++ cxx icpc KCC CC CC cc++ xlC aCC)
