Patch with check for -Wextra in elfutils doesn't really work
Last modified: 2007-11-30 17:11:00 EST
Description of problem: Patch with check for -Wextra in elfutils doesn't really work: if gcc -D_GNU_SOURCE -DHAVE_CONFIG_H -I. -I/usr/src/redhat/BUILD/elfutils- 0.101/build-i386-redhat-linux/../libcpu -I.. -I/usr/src/redhat/BUILD/elfutils- 0.101/build-i386-redhat-linux/../libcpu -Wall -Wshadow -Werror -Wextra -Wformat=2 -Wunused -O2 -g -march=i386 -mcpu=i686 -MT i386_dis.o -MD -MP -MF ".deps/i386_dis.Tpo" -c -o i386_dis.o /usr/src/redhat/BUILD/elfutils- 0.101/build-i386-redhat-linux/../libcpu/i386_dis.c; \ then mv -f ".deps/i386_dis.Tpo" ".deps/i386_dis.Po"; else rm -f ".deps/i386 _dis.Tpo"; exit 1; fi cc1: unrecognized option `-Wextra' make[1]: *** [i386_dis.o] Error 1 make[1]: Leaving directory `/usr/src/redhat/BUILD/elfutils-0.101/build-i386- redhat-linux/libcpu' make: *** [install-recursive] Fehler 1 Version-Release number of selected component (if applicable): elfutils-0.101-2 How reproducible: Everytime, see below. Steps to Reproduce: 1. Use a compiler that doesn't have -Wextra (RHEL3's gcc for example) 2. Rebuild elfutils-0.101-2 3. Die with an error Actual results: Patch with check for -Wextra in elfutils doesn't really work. Expected results: Rebuilding also should work without the -Wextra parameter. The attached patch solves the problem for me. BTW, gcc 3.2.x also has problems with the changes in src/strip.c of the elfutils-0.101-portability.patch - but I guess, this is irrelevant for Fedora Core.

This is not really a supported issue since it doesn't come up if you are using the stock compiler. Anyway, the current rawhide elfutils srpm contains a portability patch that does work with older compilers, you have to use rpmbuild --with compat to build the srpm using that patch.
