gtkwave @ 3.3.15: fails to build on Mac OS X Lion with Xcode 4.2 (clang) due to references to undefined symbols by lxtminer.o and lxt2vcd.o

[maehne (Torsten Maehne)]

The current version 3.3.15 of gtkwave available in MacPorts fails to build with the following linker errors:

...

I'm using Mac OS X Lion 10.7.2 with Xcode 4.2 (clang). Apparently, the source code is not yet compatible to clang. I succeeded to compile it by setting configure.compiler to llvm-gcc-4.2.

A patch for the Portfile is attached, which also bumps the gtkwave version to 3.3.26.

[maehne (Torsten Maehne)]

I would like to add that the upstream developer is aware of the problem ​id 3416140. The problem is marked as fixed, but a new version hasn't been released yet.

You can't just set configure.compiler to llvm-gcc-4.2 unconditionally; that will probably cause problems for Tiger and Leopard users. Read wiki:PortfileRecipes#compiler for the correct incantation.

[maehne (Torsten Maehne)]

@ryandesign: Thank you for your remark, I have updated the Portfile so that llvm-gcc-4.2 is only selected if clang has been chosen as compiler. This is reflected in the updated patch.

Patch for Portfile

#32631 claims to supersede this ticket, that 3.3.28 will build with clang.

Cc Me!

I can confirm that #32631 supersedes this ticket and gtkwave 3.3.28 compiled with clang works fine for me.
