Dyld Library Path
What matters is that I'm dlopening it using just the leaf name of the path, after setting DYLDLIBRARYPATH at runtime to include MATLAB's dir (Test 1). But when I dlopen it with the full path (Test 2) it works. LDLIBRARYPATH: native code libraries (on Linux, in addition to the value of this variable, the lookup path typically contains /usr/local/lib, /usr/lib, /lib and a few others). The name LD comes from dynamic l oa d er, the system component that loads libraries into dynamically linked executables.

- Dyld: Library not loaded: libtest.dylib Referenced from: /PATH/bin/./myapp Reason: image not found Trace/BPT trap: 5 otool -l myapp shows the rpath is correctly updated in myapp. Load command 16 cmd LCRPATH cmdsize 40 path @executablepath/./lib/ (offset 12) The same is true with libtest.dylib.
Hello, I've searched for other posts on this topic but I haven't found anything that provides an answer.
Here's my test program snippet, using the Xcode Mac Application Obj-C starter project:
Dyld_library_path Catalina
As you can see, I'm trying to dlopen a dylib in the installed MATLAB application. But I don't think the specific dylib matters. What matters is that I'm dlopening it using just the leaf name of the path, after setting DYLD_LIBRARY_PATH at runtime to include MATLAB's dir (Test 1). This fails.
But when I dlopen it with the full path (Test 2) it works. Here's the output:
I have Hardened Runtime enabled, with these entitlements turned on:
- Allow DYLD Environment Variables
- Disable Library Validation
Dyld_library_path Mac Os
The second one is doing its job, because without it, Test 2 fails also.
Dyld_library_path
But the first one doesn't help in allowing me to modify DYLD_LIBRARY_PATH at runtime. If I set the environment variable before launching (Xcode > Product > Scheme > Edit Scheme > Arguments > Environment Variables) then Test 1 works. Is there a way to get dyld to honor changes to this environment variable made at runtime?
