pandoc bottle requires gcc 4.8.3_1

[sjackman]

The pandoc Mavericks bottle requires gcc 4.8.3_1, but the current bottled version of gcc is 4.9.1. Installing the 4.8.3_1 bottle of gcc resolves the issue.

$ brew install pandoc
$ otool -L /usr/local/bin/pandoc |grep gcc
    /usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
$ ls /usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgcc_s.1.dylib
ls: /usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgcc_s.1.dylib: No such file or directory
$ brew install gcc-4.8.3_1.mavericks.bottle.1.tar.gz
$ ls /usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgcc_s.1.dylib
/usr/local/Cellar/gcc/4.8.3_1/lib/gcc/x86_64-apple-darwin13.2.0/4.8.3/libgcc_s.1.dylib

Is this a dupe of this or a separate issue?

[sjackman]

New issue, same solution. The bottle revision of pandoc needs to be bumped to force a rebuild.

[sjackman]

Also applies to any other package that is compiled with ghc.

$ brew uses ghc
cabal-install       darcs       haskell-platform    pandoc-citeproc
cgrep           git-annex       pandoc          shellcheck

I'm seeing the same issue under yosemite. What's the proposed solution?

[sjackman]

The proposed solution is to rebuild a new revision of the bottle.
A workaround is brew --build-from-source pandoc.

[DomT4]

Alright. If the bottles need redoing I think @MikeMcQuaid is the guy for that. Exercising the build from source option will resolve the issue for now, if you can put up with the slightly longer compile times.

[rob-p]

I see. I'm actually encountering an issue even earlier in the dependency chain, when trying to compile ghc. I tried to install ghc itself with the --build-from-source option, but I end up running into the same issue:

ghc --devel failed to build on 10.9.2 (https://github.com/Homebrew/homebrew/issues/30000)

But I have no idea what would cause the C compiler cannot create executable error.

Strange. What's your brew config?

@rob-p Your issue looks unrelated - mind opening a new issue with the output requested from the troubleshooting page? Thanks!

[DomT4]

@rob-p - You probably want to be using Xcode 6 with 10.10. The two are intended to compliment each other and 5.1.1 isn't really intended for Yosemite. I'd recommend updating to the Xcode beta, and downloading the applicable CLT for those and trying again.

[rob-p]

Thanks --- I'll give that a try and report back if it works.
