#896: cabal install cabal-install fails if gcc not in /Developer/usr/bin/gcc
---------------------------------+------------------------------------------
Reporter: jeremyw.sherman | Owner:
Type: defect | Status: new
Priority: normal | Milestone:
Component: cabal-install tool | Version: 1.8.0.2
Severity: normal | Keywords:
Difficulty: unknown | Ghcversion:
Platform: Mac OS |
---------------------------------+------------------------------------------
Under Mac OS X, `cabal` assumes `gcc` is at `/Developer/usr/bin/gcc`. This
fails when Xcode is installed to another directory. Xcode has supported
installing to an arbitrary folder since at least Xcode 3.x. This is
particularly common among iOS developers, as they frequently require
multiple parallel Xcode installs.
Since Xcode installs gcc to both `$DEVELOPER/usr/bin/gcc` and
`/usr/bin/gcc`, this could be fixed by using `/usr/bin/gcc` directly or
the result of a search in `$PATH` for `gcc`.
The user workaround for now is to symlink `/Xcode_4_2` (or whatever the
user's latest Xcode install directory is) to `/Developer`.
(Apple is moving from `gcc` to `clang`, anyway. Apple's `gcc` has been
frozen at an ancient version for some time now.)
