# 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", "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([Fortran]) |
||||
# AC_PROG_FC |
||||
# AC_FC_PP_SRCEXT([F]) |
||||
# AX_COMPILER_VENDOR |
||||
# AC_LANG_POP([Fortran]) |
