Few... It's working with *jl_init_with_image()*, but only using
*sys-debug.dylib
*instead of the release version... A bug? With *sys.dylib *there is some
absolute paths, I'm getting a long error in the console, which starts wtih:
*signal (11): Segmentation fault: 11*
*jl_enter_handler at
/Users/osx/buildbot/slave/package_osx10_9-x64/build/src/builtins.c:191*
...
Anyway here is the steps how to embed Julia in a Xcode project:
1. Copy /include/ and /lib/ directories from Julia.app to your Xcode's
project directory. Also I've changed directory structure from the
/lib/julia/ and /include/julia/ to just /lib/ and /include/, so in my
project's directory it's in /julia/lib and /julia/include/;
2. Change paths for libraries *libccalltest.dylib*, *libgit2.dylib*,
*libpcre2-posix.0.dylib*, *libpcre2-8.0.dylib *using install_name_tool
to *@rpath/libname.dylib *(note that some of this libraries also has
different name);
3. In the Build Settings add* $(PROJECT_DIR)/julia/lib* (/julia/lib is
relative to my project directory structure) to Runpath Search Path (this
and the first steps is required if you're planning to share your project,
in other case you can add libraries from the Julia.app);
4. In the Build Phases add all the libraries to the Link Binary With
Libraries phase;
5. Add a Copy Files phase and add all the headers and libraries to
Resources destination (here destination can be different, also you could
use different copy phase for the headers and the libraries);
6. Initialize Julia with *jl_init_with_image("Your.app/contents/directory",
"path/to/sys-debug.dylib")*
