dyld: Library not loaded: @rpath/libui.A.dylib

[cadebrown]

Hello,

I see the note in the readme which advises to add -L$(pwd) as a linker flag to avoid this error, but I am still getting it. (I'm on macos)

My project structure is essentially:

• TESTAPP/
• • lib/
• • • libui/
• • src/

When I try to do a crystal build, it reports no errors, and generates an executable ./TESTAPP, but hen I try to run it I get the "library not loaded" error

Here's the first of the output of otool -L ./TESTAPP:

./TESTAPP:
        @rpath/libui.A.dylib (compatibility version 0.0.0, current version 0.0.0)
...<< other libraries that are found >>

This problem may have something to do with my installation set up, because I have installed libui through homebrew, and my path is non standard. However, I have LD_LIBRARY_PATH and DYLD_LIBRARY_PATH set up to handle this, and it works with other libraries, but I could have missed something common.

I can get the program to run fine by running the command:

install_name_tool -change "@rpath/libui.A.dylib" "/Users/cadebrown/programs/homebrew/lib/libui.dylib" ./TESTAPP

Which manually changes it to the explicit value of the dynamic library. But, I have to do this on each crystal build and I'd rather not have a Makefile to automate this and just use crystal's system directly.

Any help would be much appreciated!

I had the same issue, and I fixed it by installing libui.

# Clone the https://github.com/andlabs/libui repo and cd into it.
$ mkdir build
$ cd build
$ cmake .. -DBUILD_SHARED_LIBS=OFF
$ make
$ sudo cp -a ./out/. /usr/local/lib/

Fixed the issue, check out my makefile I made to solve this : https://github.com/Iainmon/macOS-crystal-packaging/blob/master/Makefile
