[Matplotlib-users] Help building
I've been a long time, happy user of MPL, but I'm having some problems building the latest version (0.98.5.3) on the Mac (python 2.6.2). The bottom line is that when I build, I get the error message: ld: in /Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib/libPng.dylib, file is not o f required architecture for architecture ppc collect2: ld returned 1 exit status lipo: can't open input file: /var/folders/tu/tuLdYMqlEm00c5EVXrMQ+U+++TQ/-Tmp-// cci4zDq4.out (No such file or directory) error: command 'g++' failed with exit status 1 However, I have a freshly-built version of libpng installed from source in /usr/local/lib. I don't think MPL is finding it, though, since during config I see: libpng: found, but unknown version (no pkg-config) (However, when I install libpng, I do install the pc file, viz: cd /usr/local/lib/pkgconfig; rm -f libpng.pc cd /usr/local/lib/pkgconfig; ln -s libpng12.pc libpng.pc) I'm probably doing something dumb. Is there a workaround to this?

Re: [Matplotlib-users] Help building
What does pkg-config libpng --modversion --libs --cflags give? The pkg-config error may actually be a red herring, since matplotlib will look in /usr/local even if pkg-config fails, and it obviously found the headers or it wouldn't have gotten to the linking stage. As the author of the pkg-config support I would like to rule that out as the problem though. I think it's more likely that the libpng isn't being built correctly to match the kind of binary matplotlib is building. I'm afraid that's where I hit the end of my knowledge as a non-Mac user, but I'm sure another Mac developer will chime in.

For whatever reason, it has decided that an old version in /Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib/libPng.dylib is the proper version, despite there being a newer version in /usr/local/lib. Is there any way I can rearrange the search path so that it finds the /usr/local/lib version?

Re: [Matplotlib-users] Help building (problems with pkg-config and libpng)
I have a working system now. Here's what I did to fix it. 1. Installed libpng from source 2. Installed freetype2 from source 3. Installed pkg-config from source 4. Installed a new version of the Xcode developer tools for the mac. During the build I still saw a few 'incompatible architecture' errors flash by, but I guess they weren't serious enough for the build to stop.
