View Full Version : static binary trying to find libpng?

04-11-2012, 05:47 PM

I build a static binary gui (using wxwidgets etc.).
otool -L shows nothing but if I run it on a fresh mac (same version 10.6.8) it prints:

dyld: Library not loaded: /usr/local/lib/libpng14.14.dylib

Referenced from: /Users/noname/Downloads/mygui.app/Contents/MacOS/mygui
Reason: image not found

Trace/BPT trap

So why is it looking for libpng if otool does not show a dependency?

otool -L /Users/noname/Downloads/mygui.app/Contents/MacOS/mygui

has nothing?

no, nothing

ha, the reason was the binary was packed with upx.
Running otool on the unpacked version shows all kinds of dependencies (including the libpng).
So from here I can probably figure it out.
Is it better to link statically to libpng or is there a dynamic library installed by default (maybe in a different location) that should better be used? there is other dynamic stuff like libcrypto, libSystem, libexpat, libz, libiconv.2, libstdc++.6, libobjc.A Will they be available on a fresh user system?
