Comment (by leif):
P.S.: From `m4/mpc.m4`:
{{{
#!sh
#
# SYNOPSIS
#
#
# MPC_GMP_CC_CFLAGS
#
# DESCRIPTION
#
# Checks if CC and CFLAGS can be extracted from gmp.h
# essentially copied from mpfr
#
AC_DEFUN([MPC_GMP_CC_CFLAGS], [
AC_MSG_CHECKING(for CC and CFLAGS in gmp.h)
# AC_PROG_CPP triggers the search for a C compiler; use hack instead
for cpp in /lib/cpp gcc cc c99
do
test $cpp = /lib/cpp || cpp="$cpp -E"
echo foo > conftest.c
if $cpp $CPPFLAGS conftest.c > /dev/null 2> /dev/null ; then
# Get CC
echo "#include \"gmp.h\"" > conftest.c
echo "MPFR_OPTION __GMP_CC" >> conftest.c
GMP_CC=`$cpp $CPPFLAGS conftest.c 2> /dev/null | $EGREP
MPFR_OPTION | $SED -e 's/MPFR_OPTION //g;s/ *" *//g'`
# Get CFLAGS
echo "#include \"gmp.h\"" > conftest.c
echo "MPFR_OPTION __GMP_CFLAGS" >> conftest.c
GMP_CFLAGS=`$cpp $CPPFLAGS conftest.c 2> /dev/null | $EGREP
MPFR_OPTION | $SED -e 's/MPFR_OPTION //g;s/ *" *//g'`
break
fi
done
if test "x$GMP_CFLAGS" = "x__GMP_CFLAGS" -o "x$GMP_CC" = "x__GMP_CC" ;
then
AC_MSG_RESULT(no)
GMP_CC=
GMP_CFLAGS=
else
AC_MSG_RESULT(yes [CC=$GMP_CC CFLAGS=$GMP_CFLAGS])
fi
# Check for validity of CC and CFLAGS obtained from gmp.h
if test -n "$GMP_CC$GMP_CFLAGS" ; then
AC_MSG_CHECKING(for CC=$GMP_CC and CFLAGS=$GMP_CFLAGS)
echo "int main (void) { return 0; }" > conftest.c
if $GMP_CC $GMP_CFLAGS -o conftest conftest.c 2> /dev/null ; then
AC_MSG_RESULT(yes)
CC=$GMP_CC
CFLAGS=$GMP_CFLAGS
else
AC_MSG_RESULT(no)
fi
fi
rm -f conftest*
])
}}}
I don't exactly recall what went wrong, but `configure` gave me something
like
{{{
checking for CC and CFLAGS in gmp.h ... yes CC= CFLAGS=
}}}
and finally `gcc` was used (instead of `$CC`, while the same setting was
recorded in `gmp.h`).
