Calling the add function from Swift is possible because you defined it to have C linkage with extern “C”. Making the library a Swift module (as suggested by jtbandes in above comments) might be the better solution, but here is how you can use the function pointer return by dlsym() from Swift: First add typedef … Read more
After reading the link that Justin provided, I was successfully able to use the @executable_path token to change my dylib install_name to point to the same dir where my executable is located. @executable_path Absolute paths are annoying. Sometimes you want to embed a framework into an application instead of having to install the framework into … Read more
I guess I’ll use this question to write a canonical answer for all “image not found” issues. 1. The issue Let’s start with a minimal setup consisting of a main binary and a library, like so: main.c: #include <stdio.h> extern int f(void); int main(void) { printf(“%u\n”, f()); return 0; } xyz.c: int f(void) { return … Read more
I experienced similar problem while using OpenCV in MacOS El Capitan. Solved the problem using the solution in the link Solution is to delete some dlylibs in the /usr/local/lib directory and create symbolic links to related files /System/Library/Frameworks/ImageIO.framework/Resources/ cd /usr/local/lib rm libgif.dylib ln -s /System/Library/Frameworks/ImageIO.framework/Resources/libGIF.dylib libGIF.dylib rm libjpeg.dylib ln -s /System/Library/Frameworks/ImageIO.framework/Resources/libJPEG.dylib libJPEG.dylib rm libtiff.dylib ln … Read more
I’ve scoured Google but the only thing I can find so far is the following quote from the Apple developer forums: For those who are curious, the .tbd files are new “text-based stub libraries”, that provide a much more compact version of the stub libraries for use in the SDK, and help to significantly reduce … Read more
For some time I was thinking that this is my problem as well, but for normal apps (non-iOS-8-extension) you just need to change one build setting in your casual Xcode 6 iOS Universal Framework target (set Mach-O Type to Static Library): There should be no problem with iTunes Connect and iOS 7 after that 🙂
Find all the boost libraries (where exefile is the name of your executable): $ otool -L exefile exefile: @executable_path/libboost_something.dylib (compatibility version 0.7.0, current version 0.7.0) /usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 65.1.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 169.3.0) and for each libboost_xxx.dylib, do: $ install_name_tool -change @executable_path/libboost_something.dylib /opt/local/lib/libboost_something.dylib exefile and finally verify using otool … Read more
I’m not really disagreeing with DarkDust’s answer, but if I may channel my inner Bill Clinton, it depends on what the meaning of supported is 🙂 Apple doesn’t want you doing this for App Store apps, but the operating system certainly allows it. Jailbreak apps use this technique all the time. You basically use a … Read more
