Sorry, forgot to CC maintainer and can't change it afterwards

I do not have access to Xcode 4.2 pre-releases and so far it should be considered unsupported as it is unreleased software.

I guess the upstream Xcode project is just not yet ready for this as it assumes gcc-4.2 to be available.

I tried to build MacVim using clang but unfortunately I wasn't able to open any vim window with this build. I tried ​the troubleshooting instructions but couldn't find anything helpful in the logs. It just doesn't open any window.

Same problem occurs on Lion 10.7.2 with Xcode 4.2 (released version).

[benedikt.meurer@…]

Attached Portfile diff and patches to fix the build issues with missing GCC 4.2 (based on upstream fix at ​https://github.com/b4winckler/macvim/commit/54b2b3cf5e39b12181d2ede9cc49f5601a5ffaba).

The problem with clang version not opening any windows remains, tho.

BTW. it works using llvm-gcc (and my patches), i.e.:

sudo port install MacVim configure.compiler=llvm-gcc-4.2

[raimue (Rainer Müller)]

Thank you for the patch!

Committed in r86143 in addition with switching to llvm-gcc-4.2 if clang is selected.

Reopening. We need to figure out *why* it's failing with clang and fix/report the underlying issue.

[jeremyhu (Jeremy Huddleston Sequoia)]

Does it still happen with the clang in XCode 4.3?

MacVim @7.3.snapshot64_0 builds without issue using Xcode-4.3.x for me.

[skymoo (Adam Mercer)]

Sorry, just to clarify, I commented out

if {${configure.compiler} == "clang"} {
    configure.compiler llvm-gcc-4.2
}

from the Portfile and it built fine using clang.

The compilation has always been working but the resulting MacVim does not work correctly in a way where it would not open new windows. Upstream also compiles using llvm-gcc. I just tried with Xcode 4.3 and although it builds, it still does not work correctly.

Replying to raimue@…:

Not according to the title nor the contents of this radar ;)

Unfortunately upstream doesn't really give much info... hmm...

I just compiled snapshot 64 of MacVim with clang from Xcode 4.4 on Mac OS X 10.7 Lion. The build went fine and the resulting binary can open new windows just fine.

MacVim is now being built with clang when using Xcode >= 4.4 as of r95886.
