I have built gcc before from the Fedora source package, most recently GCC 4.4 in F13, and there was no issue other than a minor tweak to the spec file that I had to do. Now I am on F14, and got the errors further down [1] when building GCC 4.5.1. Searching Google the only thing I could find that seemed similar was the email below, though it referred to a build for 64 bits (I am building on a 32 bits machine for 32 bits): http://gcc.gnu.org/ml/gcc-regression/2010-11/msg00435.html Fedora does ship the RPM so obviously they managed to successfully build the package. One difference is that they have their own build system and likely build on a 64 bits machine. Any ideas about what could be wrong with my build or how can I diagnose what is wrong? =========== [1] <snip> checking linker PT_GNU_EH_FRAME support... yes checking linker position independent executable support... yes checking linker EH-compatible garbage collection of sections... yes checking linker --as-needed support... yes checking linker --build-id support... yes checking linker *_sol2 emulation support... no checking linker --sysroot support... yes checking __stack_chk_fail in target C library... yes Using ggc-page for garbage collection. checking whether to enable maintainer-specific portions of Makefiles... no Links are now set up to build a native compiler for i686-redhat-linux-gnu. checking for exported symbols... yes checking for -rdynamic... yes checking for library containing dlopen... -ldl checking for -fPIC -shared... yes configure: updating cache ./config.cache configure: creating ./config.status config.status: creating as config.status: creating collect-ld config.status: creating nm config.status: creating Makefile config.status: creating gccbug config.status: creating ada/gcc-interface/Makefile config.status: creating ada/Makefile config.status: creating auto-host.h config.status: executing default commands make[2]: Leaving directory `/home/xx/develt/rpmbuild/BUILD/gcc-4.5.1-20100924/obj-i686-redhat-linux' make[1]: *** [stagefeedback-bubble] Error 2 make[1]: Leaving directory `/home/xx/develt/rpmbuild/BUILD/gcc-4.5.1-20100924/obj-i686-redhat-linux' make: *** [profiledbootstrap] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.qPSxRm (%build) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.qPSxRm (%build)
