From cce81a748fc4f69de944ff0ae8cb1a59b6194308 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Fri, 21 Aug 1998 17:43:22 +0000 Subject: A patch from Ralf Corsepius : Here is another patch to hopefully enhance rtems' configuration. Motivation: Try to support other c-compilers besides gcc (I tried to build rtems under Solaris using sun's WSPro c-compiler). Here is a couple of small patches concerning the host compiler configuration, which fix/work-around the worst problems when using sun's WSPro c-compiler. Changes: * Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie. gcc.cfg is generated by configure now. * Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix). * Add -g to host compiler flags only if configure reported -g to work * Add -Wall to host compiler flags only if configure reported that the host compiler is gcc (WSPro's cc chokes on -Wall). * Some modifications to make/Makefile.in * Adapted make/custom/default.cfg to the new location of gcc.cfg BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS etc.) which deserves to be cleaned up, IMO. IMO, a similar patch should be applied to gcc-target-default.cfg --- configure | 93 ++++++++++++++++++++++++++++++++++----------------------------- 1 file changed, 51 insertions(+), 42 deletions(-) (limited to 'configure') diff --git a/configure b/configure index 24ed28da49..688d4e03dd 100644 --- a/configure +++ b/configure @@ -2667,15 +2667,18 @@ case $host_os in esac +test "$ac_cv_prog_gcc" = "yes" && CC_CFLAGS_DEFAULT=-Wall +test "$ac_cv_prog_cc_g" = "yes" && CC_CFLAGS_DEBUG_V=-g + for ac_func in strerror do echo $ac_n "checking for $ac_func""... $ac_c" 1>&6 -echo "configure:2674: checking for $ac_func" >&5 +echo "configure:2677: checking for $ac_func" >&5 if eval "test \"`echo '$''{'ac_cv_func_$ac_func'+set}'`\" = set";
