problem building gcc 4.3.2

[Galen Seitz]

Hi,

I'm trying to build RHEL/CentOS packages that match the latest winavr
release.  I've downloaded Eric's patches and incorporated them into
the build process.  The build dies during libgcc with this error:

Configuring in avr/libgcc

checking for --enable-version-specific-runtime-libs... no

See `config.log' for more details.


When I look at avr/libgcc/config.log, I see that xgcc is being passed
i386 options, which can't be correct:

configure:2588: /home/galens/rpm/BUILD/avr-gcc-4.3.2/build/./gcc/xgcc
-B/home/ga

cc1: error: unrecognized command line option "-march=i386"
cc1: error: unrecognized command line option "-mtune=generic"
conftest.c:1: warning: unwind tables currently require a frame pointer
for corre
ctness


I haven't been able to figure out what I've done wrong.  Do Eric's gcc
patches require a bootstrap?  If so, what is the recommend way of
doing this?

thanks,
galen

What says "echo $CC"? Setting CC so some value can lead to errors AFAIR.
Maybe same happens for CFLAGS, or you did not configure gcc correctly
(like obj-path as subdir of source-path).

It sounds like avr-binutils is not in the PATH.

Please note that this is what I do in my scripts to build binutils:

make maybe-configure-bfd 2>&1 | tee $project-make-configure-bfd.log
make -C bfd headers 2>&1 | tee $project-make-headers.log
make all html install install-html 2>&1 | tee $project-make.log


HTH,
Eric

Thanks for the response.  You correctly guessed the problem.  The rpm
spec file was setting some compiler environment variables.  When I
removed those lines, the problem was eliminated.
