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.in | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'configure.in') diff --git a/configure.in b/configure.in index 1ee614dedd..d08245faa6 100644 --- a/configure.in +++ b/configure.in @@ -240,6 +240,12 @@ case $host_os in esac AC_SUBST(GCCSED) +dnl FIXME: This is a kludge +dnl Add -Wall if using gcc as host compiler +test "$ac_cv_prog_gcc" = "yes" && CC_CFLAGS_DEFAULT=-Wall +dnl Add -g if the host compiler accepts -g, assume -g means debugging +test "$ac_cv_prog_cc_g" = "yes" && CC_CFLAGS_DEBUG_V=-g + dnl check for host library functions dnl NOTE: must be called after AC_PROG_CC AC_CHECK_FUNCS(strerror) @@ -448,6 +454,8 @@ AC_SUBST(BARE_CPU_CFLAGS) AC_SUBST(BARE_CPU_MODEL) AC_SUBST(PROJECT_ROOT) AC_SUBST(program_prefix) +AC_SUBST(CC_CFLAGS_DEFAULT) +AC_SUBST(CC_CFLAGS_DEBUG_V) # pick up all the Makefiles in required parts of the tree RTEMS_CHECK_MAKEFILE(c/build-tools) @@ -463,6 +471,7 @@ Makefile make/host.cfg make/target.cfg make/Templates/Makefile.inc +make/compilers/gcc.cfg c/Makefile c/src/Makefile c/src/exec/Makefile -- cgit v1.2.3
