Hi, I think I jumped the gun and filed bug report #5292 without completely understanding what's going on. I have some questions: On MacOSX, it seems that the libraries that are included with the Wireshark.dmg installer from wireshark.org are not properly linked. When running otool -L on them (e.g. libwireshark.dylib), the library thinks it's "id" (the second line in the output) is /usr/local/lib/libwireshark.dylib rather than /Applications/Wireshark.app/Contents/Resources/lib/libwireshark.dylib. If libwireshark.dylib is not being dlopen()'ed, how is Contents/MacOS/Wireshark being able to load libwireshark.dylib without encountering an error? Is there an implicit environment variable being set somewhere? I am relatively new at developing for MacOSX. You may be question the reason for why I am interested in this. I developed a GPLv2 tool for Linux that allows Wireshark's packet dissection engine to be used in high-level interpreted programming languages (Python and Matlab in particular) to extract vectors of packet information for subsequent post-processing and analysis. I have ported the tool to MacOSX, but since I link with libwireshark, libwiretap, libwsutil directly, I'd rather link with existing copies of the library on my installation target rather than distribute Wireshark libraries with my tool. With respect to the above problem, I was unable to load Wireshark.app's libraries unless I ran "install_name_tool -id" and "install_name_tool -change" on each library that comes with Wireshark.app. Any insight is greatly appreciated. Thanks!
