arb: clang from Xcode 4.3.1 crashes

[matt.cottrell@…]

The attached portfile diff now sets llvm-gcc-4.2 as the compiler for the arb port. The version of clang (Apple clang version 3.1) supplied with Xcode 4.3.1 crashes while building arb.

Also, the attached patch-ARB-makefile.diff fixes some problems with graphics libraries that I have now finally gotten around to fixing.

Is the clang crash something you have already reported to Apple? Is the problem still present in Xcode 4.3.2?

Resolves problem with patch not applying

[matt.cottrell@…]

The problem still remains with Xcode 4.3.2. I have not reported this to Apple yet, but I will. The focus has been on an immediate fix because I am receiving many messages from arb users who are unable to install arb.

[matt.cottrell@…]

I am working with the upstream developer to determine if this is a problem with the arb source or Apple clang version 3.1 (tags/Apple/clang-318.0.58) (based on LLVM 3.1svn).

The key error appears to be:

GEP is not of right type for indices!

Have not found a solution to that one yet.

On the other hand, the solution to the error

warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated

is easy and we have made those adjustments by adding

-x c++

where necessary.

In the mean time, I would very much like to use llvm-gcc-4.2 to compile arb now. That works. We are working on sorting out the clang errors.
