Re: [Tinycc-devel] macos: DYLD_LIBRARY_PATH no longer works after cleanup

[Christian Jullien]

Michael,

If you have a moment, can you please test if my macos fix for dyld also works 
on your configuration?
My changes tell tcc to find dyld in the same directory as it binary. Clearly, 
DYLD_LIBRARY_PATH can't be use as, for security reasons, it is reset when call 
subprocess.

Thx.

Hmm, can't reproduce here:

% git log -1 --online HEAD
9d75f14 Fix structure passing i386 PE
% make clean
% ./configure --disable-static
...
Config              OSX static=no
...
% make
% make test
... works ...

(Note the double dash for configure options, I'm not sure if it was just a typo 
in your mail).  And there's proof that the export from the Makefile does work, 
because calling tcc from the tests directory directly indeed doesn't work:

% cd tests; ../tcc -h
dyld: Library not loaded: libtcc.dylib
   Referenced from: /Users/micha/src/tinycc/tests/../tcc
   Reason: image not found
Abort trap: 6

So that the testsuite works for me is the indication that the 'export 
DYLD_LIBRARY_PATH' construct does work (for me).  Any differences in make 
behaviour perhaps?
