Hello,
I'm working on a project depending on OpenGL, X11 and libpng.
I've compiled the libpng library from the sources, which create
the .dylib file with the following version informations :
-current_version 0.1.2.8 -compatibility_version 0.1.2.8
Everything work until I tried to launch my program. The dynamic
loader says :
dyld: Library not loaded: /System/Library/Frameworks/
ApplicationServices.framework/
Versions/A/Frameworks/ImageIO.framework/Versions/A/Resources/
libPng.dylib
Referenced from: /System/Library/Frameworks/
ApplicationServices.framework/
Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO
Reason: Incompatible library version: ImageIO requires version
1.0.0 or later,
but libpng12.0.dylib provides version 0.1.2
(Apple X11 libGL.dylib need ApplicationServices.framework which
itself need ImageIO)
However, Apple's version did not export any useful symbols, so I
can't use the ImageIO/libPng.dylib lib, I must use my home-compiled
version.
Any ideas to solve this problem ?
repackage the library with the correct values.
mkdir /libfix
# save the libs in case we have a probelm
(cd /usr/local/lib && tar cf - libpng.* | (cd /libfix && tar xf -))
libtool -dynamic -o /usr/local/lib/libpng12.0.1.2.8.dylib -framework
ApplicationServices -lSystem -lz -lcc_dynamic -compatibility_version
1.0.0 -current_version 1.0.2 -arch_only ppc /usr/local/lib/libpng.a
