[pure-lang-users] dyld: Library not loaded: libpure-0.4.dylib

[Ryan S. <rya...@us...>]

I noticed that pure doesn't actually run on Mac OS X anymore because  
it can't find libpure. This occurs with pure 0.4 and also with the  
version of pure 0.5 in trunk @438. I tested on Mac OS X 10.4.11 and  
10.5.4, both on Intel. Here is the error that occurs with 0.4:


$ pure
dyld: Library not loaded: libpure-0.4.dylib
   Referenced from: /mp/bin/pure
   Reason: image not found
Trace/BPT trap
$


And the reason looks to be that pure is linking with libpure without  
specifying the directory it's located in:


$ otool -L /mp/bin/pure
/mp/bin/pure:
         libpure-0.4.dylib (compatibility version 0.0.0, current  
version 0.0.0)
         /mp/lib/libiconv.2.dylib (compatibility version 7.0.0,  
current version 7.0.0)
         /mp/lib/libreadline.5.2.dylib (compatibility version 5.0.0,  
current version 5.2.0)
         /mp/lib/libgmp.3.dylib (compatibility version 8.0.0, current  
version 8.2.0)
         /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0,  
current version 7.4.0)
         /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0,  
current version 1.0.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0,  
current version 88.3.10)
$


It works if I tell it where the libraries are when I run pure:


$ DYLD_LIBRARY_PATH=/mp/lib pure

But obviously you don't want users to have to give DYLD_LIBRARY_PATH  
every time they want to use pure.


Finally, "libpure-0.5.dylib" is a peculiar name; I would have  
expected something more like "libpure.0.5.dylib".
