[issue2936] ctypes.util.find_library() doesn't consult LD_LIBRARY_PATH

[Bill Janssen]

Bill Janssen <[EMAIL PROTECTED]> added the comment:

The question is, which linker?  I think it should be ld.so, which links "on
demand", and does pay attention to LD_LIBRARY_PATH.  I'm not sure what the
point of find_library() is, otherwise.

To be honest, &nbsp;I do not understand this request and the discussion.<br>
ctypes.util.find_library(), as dcumented, is supposed to simulate what<br>
the linker does: &nbsp;find the name of a shared library. &nbsp;For example,<br>
it returns &#39;libc.so.6&#39; when called as 
ctypes.util.find_library(&#39;c&#39;).<br>
AFAIK (and I don&#39;t know very much about posix shared libs or linkers)<br>
the linker does not pay attention to (DY)LD_LIBRARY_PATH env var.<br>
<br>
dlopen(shared-lib-name) does use this env vars, but this behaviour is<br>
already built into dlopen.<br>
