Which version of python are you using? The Python.org installer builds extensions using the 10.4 SDK to ensure that extensions will actually run on that platform.

BTW. What I don't undestand is why building PIL tries to link libcrypto.

Do you have a libcrypto dylib in /usr/local/lib? If so, what is the output of the file command on that? (file /usr/local/lib/libcrypto*). It seems that the libcrypto that's linked into the extension is PPC- only, while distutils tries to build a 32-bit universal binary.

Hello all,

I'm trying to compile the image library PIL 1.1.6, using their setup.py
(python 2.4  on OX10.5) and
gcc (i686-apple-darwin9-gcc-4.0.1) loader is throwing a build error:
-----------
building '_imagingtk' extension

which is fair enough, but- why is setup.py looking for /Developer/ SDKs/
MacOSX10.4u.sdk?
even though MacOSX10.5.sdk is also at Developer/SDKs/

Is there any reason to keep MacOSX10.4.sdk hanging around?
I moved it out of the way and setup.py puts this together for
compilation:
-----------
building '_imagingmath' extension
gcc -arch ppc -arch i386 -isysroot /Developer/SDKs/MacOSX10.4u.sdk -
fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd -
fno-common -dynamic -DNDEBUG -g -I/System/Library/Frameworks/
Tcl.framework/Headers -I/System/Library/Frameworks/Tk.framework/
Headers -IlibImaging -I/opt/local/include -I/Library/Frameworks/
Python.framework/Versions/2.4/include -I/usr/local/include -I/usr/
include -I/Library/Frameworks/Python.framework/Versions/2.4/include/
python2.4 -c _imagingmath.c -o build/temp.macosx-10.5-fat-2.4/
_imagingmath.o
-----------
i.e it still want to reference /Developer/SDKs/MacOSX10.4u.sdk

Any clues?
(golly, I hope this is the right list for this ! :-)

thanks,
David
