64 bits compile fails on OS X

[Geoffroy]

Apparently libz.dylib and libjpeg.dylib installed from ports are 32 bits. I don't know if there is a way to pull 64 versions.

I know this is similar to ​http://trac.wildfiregames.com/ticket/660, but this ticket has been closed and the problem persists, or reappeared, with alpha 8.

Trunk compile fine for me. This is not really an 0ad bug as far as I am concerned.

You can look at: ​https://trac.macports.org/wiki/howto/buildUniversal to find out how to build universal. If your building with 10.6 or 10.7 you wont get powerpc but you will get i386 and x86_64 support.

Please don't close tickets until someone on the dev team has had a look.

Replying to Geoffroy:

Apparently libz.dylib and libjpeg.dylib installed from ports are 32 bits. I don't know if there is a way to pull 64 versions.

There is, but the question is why it wouldn't build on your system. Do you have the latest MacPorts, have you done sudo port selfupgrade and sudo port upgrade outdated? Of course if you only just installed MacPorts, that doesn't matter as much.

What's the result of running these commands:

uname -a
gcc --version
file /usr/local/lib/libjpeg.dylib

I had a strange problem building libVorbis from source on Lion, its configure script incorrectly detected a 32-bit architecture, despite the fact that every other lib I tried building detected 64-bit. That caused a few headaches.

[Geoffroy]

I just installed macport, so I don't think this matter.

I tried to reinstall the concerned libraries, but that didn't changed anything.

[historic_bruno]

This will hopefully be fixed by #1112. Until then, is MacPorts still broken? It really sounds like an autoconf problem with those packages, since I've built them as 64-bit with no problem (though not with MacPorts). In the meantime, you might try these alternate build instructions for Mac which use ​Homebrew instead: MacBuildInstructions.

[historic_bruno]

Closing this as a build environment problem, see http://www.wildfiregames.com/forum/index.php?showtopic=16411. Mac Ports doesn't support other conflicting build systems and files in e.g. /usr/local, which is what is causing the above problem. You need to remove those files or force NVTT to build with Mac Ports libs somehow.
