Hi everyone,
I am trying to build the latest svn trunk version of MPL on OS X 10.5. I am
getting the following error:
ld: in /Developer/SDKs/MacOSX10.4u.sdk/usr/local/lib/libPng.dylib, file is
not of required architecture for architecture ppc
After googling quite a bit, this seems to be quite a common problem.
However, I could still not find an unambiguous solution. I have build
libpng from source on my machine. The file output is:
laser...@hobbes:/usr/local/lib$ file libpng*
libpng.3.dylib: Mach-O dynamically linked shared library i386
libpng.a: current ar archive random library
libpng.dylib: Mach-O dynamically linked shared library i386
libpng.la: ASCII English text
libpng12.0.dylib: Mach-O dynamically linked shared library i386
libpng12.a: current ar archive random library
libpng12.dylib: Mach-O dynamically linked shared library i386
libpng12.la: ASCII English text
It appears that the compiler expects that libpng will also have libraries
for ppc. What do I do? Do I need to rebuild libpng to be universal? (How
is this done?) Or do I need to somehow tell distutils to build MPL only for
i386? (How is thid done?)
Below is the full build output. Thanks for your help!
