gcc: Bootstrap comparison failure!

[wuziniu]

I'm trying on install gcc using linuxbrew without sudo. I followed the instruction as in https://github.com/Linuxbrew/brew/wiki/CentOS6#install-linuxbrew-on-centos-6-without-sudo The error encountered when running command: HOMEBREW_NO_AUTO_UPDATE=1 HOMEBREW_BUILD_FROM_SOURCE=1 brew install gcc --without-glibc is described in https://gist.github.com/wuziniu/5fc96415400f1e0ce57636a5d0ff63b7

Hi. Thanks for reporting. Are you using gcc 4.9.4 to compile gcc? If yes, then this is the bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71399

In that case this has nothing to do with linuxbrew and we can’t help you further

@iMichka Thanks for your reply. No my gcc version is 4.4.7 $ gcc --version gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-18) It this version too old?

I'm afraid I haven't run into this issue myself. Perhaps try…

HOMEBREW_NO_AUTO_UPDATE=1 HOMEBREW_BUILD_FROM_SOURCE=1 brew install gcc@4.9 --without-glibc
HOMEBREW_NO_AUTO_UPDATE=1 brew install glibc
HOMEBREW_NO_AUTO_UPDATE=1 brew install gcc

[wuziniu]

Thanks, but I got the same error as before. The make takes more than half hour. Is that a normal situation?

[sjackman]

Installing GCC from source can be quite slow. I'd say half an hour is normal. Did you get the same error after the brew install gcc@4.9 step?
