# SYNOPSIS
|
|
#
|
|
# AX_PROG_CC_FOR_BUILD
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro searches for a C compiler that generates native executables,
|
|
# that is a C compiler that surely is not a cross-compiler. This can be
|
|
# useful if you have to generate source code at compile-time like for
|
|
# example GCC does.
|
|
#
|
|
# The macro sets the CC_FOR_BUILD and CPP_FOR_BUILD macros to anything
|
|
# needed to compile or link (CC_FOR_BUILD) and preprocess (CPP_FOR_BUILD).
|
|
# The value of these variables can be overridden by the user by specifying
|
|
# a compiler with an environment variable (like you do for standard CC).
|
|
#
|
|
# It also sets BUILD_EXEEXT and BUILD_OBJEXT to the executable and object
|
|
# file extensions for the build platform, and GCC_FOR_BUILD to `yes' if
|
|
# the compiler we found is GCC. All these variables but GCC_FOR_BUILD are
|
|
# substituted in the Makefile.
