dyld

I have project in Swift and when I measure with DYLD_PRINT_STATISTICS I can see 1.0 second pre-init time, where 70% is dynamic libraries linking. Are there any clean and safe ways of dealing with this problem? According to Apple's WWDC 2016 Session on Optimizing App Startup Time , regardless of their size, having a large number of dynamically linked libraries slows down app launch time dramatically. To fix this, several dynamic libraries can be merged into a single library. If they are already static libraries , then libtool can be used to combine them, using the command from this SO answer .

I'm working on an OpenGL project, it compiles fine, running it gives the following error: swr-130-64-133-128:assignment Marcella$ ./run dyld: lazy symbol binding failed: Symbol not found: _gliCreateContextWithShared Referenced from: /System/Library/Frameworks/OpenGL.framework/Resources/GLEngine.bundle/GLEngine Expected in: flat namespace dyld: Symbol not found: _gliCreateContextWithShared Referenced from: /System/Library/Frameworks/OpenGL.framework/Resources/GLEngine.bundle/GLEngine Expected in: flat namespace I've gathered that this means there's a missing symbol in the OpenGL framework.

I have a program (specifically my entry for the SO DevDays Countdown app challenge ) which relies on several dynamic libraries, namely libSDL, libSDL_ttf, and others. I have these libraries installed under /opt/local/lib via MacPorts, and many people won't have these installed (and some might have them installed, but not at that location). How do I distribute my program so that people without these libraries installed can run it out-of-the-box? Obviously I'll have to distribute the various .dylib files, but doing this is insufficient. The dynamic loader still looks for the libraries installed

Anyone please help.. How can I fix the following error: dyld: Library not loaded: /usr/local/lib/libgdbm.4.dylib Referenced from: /usr/local/bin/zsh Reason: image not found Simple reinstall zsh will help you: brew reinstall zsh && brew unlink zsh && brew link zsh Alternatively you can try to upgrade zsh brew upgrade zsh Late to the party on this one, but simply running brew upgrade zsh solved my issue on MacOS High Sierra. Trying to uninstall gdbm will throw dependency errors against zsh and python , and re-doing the symlinks didn't solve for me, either I suspect you are running into problems
