Adolfo, Thanks for the bug report. What I see is that the sub-configure we run to get 32-bit libs is setting CC='gcc -m32', but that the CFLAGS contains '-m64'. I find that my own gcc fails with a less than useful error message in this case (though -m64 followed by -m32 does work). $ gcc -m32 -c foo.c && echo OK OK $ gcc -m64 -c foo.c && echo OK OK $ gcc -m64 -m32 -c foo.c && echo OK OK $ gcc -m32 -m64 -c foo.c && echo OK /tmp/ccCkYECv.s: Assembler messages: /tmp/ccCkYECv.s:10: Error: bad register name `%rbp' /tmp/ccCkYECv.s:12: Error: bad register name `%rsp' /tmp/ccCkYECv.s:14: Error: bad register name `%rsp' /tmp/ccCkYECv.s:16: Error: bad register name `%rbp)' /tmp/ccCkYECv.s:17: Error: bad register name `%rbp)' /tmp/ccCkYECv.s:18: Error: bad register name `%rbp)' /tmp/ccCkYECv.s:19: Error: bad register name `%rbp)' /tmp/ccCkYECv.s:20: Error: bad register name `%rbp)' Regardless of whether is works or not, the "-m64" in the CFLAGS is never the "right thing" to do here. Unless you say otherwise, I am going to assume that your distribution has chosen the values of CFLAGS and CXXFLAGS. Correct me if I am wrong here. I am looking into what can be done more cleanly, but suggest for now that you will need to edit the specfile (rpm/specfile in the build dir) to set CFLAGS to something w/o the "-m64", just above the line that begins "%configure '--enable-multilib'". -Paul Adolfo J.
