Racket won’t build on Lion

[ELLIOTTCABLE]

The plt-racket package (PLT-Scheme/Racket) won’t build for me. I’m on OS X Lion (Developer Preview 2), which I suspect to be related to the issue.

All of the relevant output is provided in this gist: https://gist.github.com/946268

(P.S. I’m not even sure if Racket itself is prepared to work on Lion; I’m posting this issue to get the ball rolling, and get others looking into it, as I’m far too much of a lisp noob to have any idea what to do. I found this post to the Racket mailing list, which might provide more information: http://lists.racket-lang.org/dev/archive/2011-April/006128.html)

(P.P.S. I give you permission to tell my mother that I am a mean person for running a Lion Developer Preview with the Lion Xcode build, and yet reporting a bug. Her phone number is +1 (907) 748-4862.)

Could try adding one or more of:

fails_with_llvm

ENV.x11

depends_on 'cairo'

in the appropriate places.

Tried that; just finished building. Still fails, same error, with all three added.

Hi,
I had some build failures as well, on Snow Leopard, using the latest XCode. However, just specifying racket version 5.1.1 fixed the issue:

No luck.

Same as above, but adding fails_with_llvm: https://gist.github.com/961102

After posting more issues to the Racket mailing list, we came up with a solution that works outside Homebrew for Mac OS X Lion DP3: http://lists.racket-lang.org/users/archive/2011-May/045392.html

Unfortunately, within Homebrew, the same fix doesn’t work. Apply the following if you’re following along at home and want to try it:

Here’s the Homebrew output from the above: https://gist.github.com/962212

Cairo is "keg-only", so the build system will probably need more help finding it.

[mxcl]

Something is trying to dynamically load libcairo at runtime. The error is that it can't find it.

Lion provides one (possibly still too old) it’s in /usr/X11/lib, so it should be able to find that at least.

If the problem is that it wants the Homebrew one then you probably need to set the DYLIB_LIBRARY_PATH environment variable. (I probably got the variable name wrong there, I can’t remember it).

[wolverian]

FWIW, the 5.1.2 tag builds on Lion. It's still dynamically looking for cairo, though.

[adamv]

Pushed 5.1.3 in 6c52429 - someone on Lion test this.

Closing this then...
