# =========================================================================== # www.gnu.org/software/autoconf-archive/ax_compiler_vendor.html # =========================================================================== # # SYNOPSIS # # AX_COMPILER_VENDOR # # DESCRIPTION # # Determine the vendor of the C, C++ or Fortran compiler. The vendor is # returned in the cache variable $ax_cv_c_compiler_vendor for C, # $ax_cv_cxx_compiler_vendor for C++ or $ax_cv_fc_compiler_vendor for # (modern) Fortran. The value is one of “intel”, “ibm”, “pathscale”, # “clang” (LLVM), “cray”, “fujitsu”, “sdcc”, “sx”, “nvhpc” (NVIDIA HPC # Compiler), “portland” (PGI), “gnu” (GCC), “sun” (Oracle Developer # Studio), “hp”, “dec”, “borland”, “comeau”, “kai”, “lcc”, “sgi”, # “microsoft”, “metrowerks”, “watcom”, “tcc” (Tiny CC) or “unknown” (if # the compiler cannot be determined). # # To check for a Fortran compiler, you must first call AC_FC_PP_SRCEXT # with an appropriate preprocessor-enabled extension. For example: # # AC_LANG_PUSH() # AC_PROG_FC # AC_FC_PP_SRCEXT() # AX_COMPILER_VENDOR # AC_LANG_POP() # # LICENSE # # Copyright © 2008 Steven G.
