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

[Christian Jullien]

Thank you for testing, make is the same:
jullien@jacquet:~/tinycc $ make -v
GNU Make 3.81
Copyright (C) 2006  Free Software Foundation, Inc.

Single dash was an automatic edit from my email agent. I pass of course 2 dashes

I tested on High Sierra which uses bash and Catalina which uses zsh. It fails 
the same on both systems.

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?
