"hello world" on macOS Mojave and miniconda - dyld: Library not loaded

Hello all, first try with miniconda installation of Nuitka, with a simple hello-world script on macOS Mojave. Here the key info:

• Python and Nuitka version:

nuitka: 0.6.5
Python: 3.7.4 (default, Aug 13 2019, 15:17:50) 
OS: Darwin
Arch: x86_64

• Tested both with Python3 and Nuitka installed from conda-forge and with Python3 from miniconda main and Nuitka installed from PyPI.

• Compiled with: python -m nuitka hello.py tried also with --standalone

• hello.py source from Nuitka documentation:

def talk(message):
    return "Talk " + message

def main():
    print(talk("Hello World"))

if __name__ == "__main__":
    main()

• No error at compile time (also checked with --verbose and --show-scons)

• Always get the following error at runtime:

dyld: Library not loaded: @rpath/libpython3.7m.dylib
  Referenced from: /Users/gioboske/dev/nuitka/hello.dist/./hello
  Reason: image not found
Abort trap: 6

Am I missing something obvious? Thank you.

Finally, I found some time to debug, following your suggestion to look into the code in nuitka.freezer.Standalone for otool output.

As far as I understood, nuitka finds no “rpaths” (in _detectBinaryRPathsMacOS): while processing the output of otool -l on the executable, only the cmd LC_RPATH load commands are considered. Unfortunately, no cmd LC_RPATH are present in the output of otoll -l and @rpath/libpython3.7m.dylib only appears as follows:

Load command 13
          cmd LC_LOAD_DYLIB
      cmdsize 56
         name @rpath/libpython3.7m.dylib (offset 24)
   time stamp 2 Thu Jan  1 01:00:02 1970
      current version 3.7.0
compatibility version 3.7.0

I think this explains why the library is not copied in the dist folder. , but I didn’t get why the error persists also when compiling without the --standalone option, manual copying the library next to hello.bin. In addition, since the library is not included in dll_map variable, the install_name_tool is not called, so the error persists also manual copying the library next to executable.

@kayhayen, do you have some additional suggestions?
