Question & Answer :
Once attempting to tally an executable I’ve been dispatched successful Mac OS X, I acquire the pursuing mistake
dyld: Room not loaded: libboost_atomic.dylib Referenced from: /Customers/"Listing my executable is successful" Ground: representation not recovered Hint/BPT entice:5
I person put in the enhance libraries and they are positioned successful /choose/section/lib. I deliberation the job has thing to bash with the executable lone wanting successful the listing it is successful arsenic once I paste the ’libboost_atomic.dylib’ successful location, it doesn’t head astir it anymore. Unluckily past it complains it tin’t discovery the adjacent enhance room.
Is location an casual manner to hole this?
Discovery each the enhance libraries (wherever exefile is the sanction of your executable):
$ otool -L exefile exefile: @executable_path/libboost_something.dylib (compatibility interpretation zero.7.zero, actual interpretation zero.7.zero) /usr/lib/libc++.1.dylib (compatibility interpretation 1.zero.zero, actual interpretation sixty five.1.zero) /usr/lib/libSystem.B.dylib (compatibility interpretation 1.zero.zero, actual interpretation 169.three.zero)
and for all libboost_xxx.dylib, bash:
$ install_name_tool -alteration @executable_path/libboost_something.dylib /choose/section/lib/libboost_something.dylib exefile
and eventually confirm utilizing otool once more:
$ otool -L exefile exefile: /choose/section/lib/libboost_something.dylib (compatibility interpretation zero.7.zero, actual interpretation zero.7.zero) /usr/lib/libc++.1.dylib (compatibility interpretation 1.zero.zero, actual interpretation sixty five.1.zero) /usr/lib/libSystem.B.dylib (compatibility interpretation 1.zero.zero, actual interpretation 169.three.zero)
Manpages: otool install_name_tool
EDIT A piece backmost I wrote a python book (copy_dylibs.py) to activity retired each this material mechanically once gathering an app. It volition bundle ahead each libraries from /usr/section oregon /choose/section into the app bundle and hole references to these libraries to usage @rpath. This means you tin easy instal 3rd-organization room utilizing Homebrew and bundle them conscionable arsenic easy.
I person present made this book national connected github.
