I want to replace gcc4.8 with gcc4.4 because C/C++ Binaries double in size for Centos 7 compared to Centos6. Centos 6 uses gcc4.4 and centos7 uses gcc 4.8. So I was trying to build gcc 4.4 rpm for centos7 using mock build but I'm getting build error. Please find the build log below. sinput.adb:776:19: deallocation from empty storage pool make[3]: *** [ada/sinput.o] Error 1 make[3]: *** Waiting for unfinished jobs.... make[3]: Leaving directory `/builddir/build/BUILD/gcc-4.4.7-20120601/obj-i686-redhat-linux/gcc' make[2]: *** [all-stage1-gcc] Error 2 make[2]: Leaving directory `/builddir/build/BUILD/gcc-4.4.7-20120601/obj-i686-redhat-linux' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/builddir/build/BUILD/gcc-4.4.7-20120601/obj-i686-redhat-linux' make: *** [profiledbootstrap] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.dHhp5l (%build) RPM build errors: Bad exit status from /var/tmp/rpm-tmp.dHhp5l (%build) Child return code was: 1 please help me to solve this -- Sent from: http://gcc.1065356.n8.nabble.com/gcc-Help-f629689.html
