Original changes in python27/Makefile r1.62-r1.67
=================================================
Add an option for Python: x11
Fix dlopen(3) calls in _ctypes.so for X11BASE libraries
A Python code can dynamically load shared libraries and it's wrapped with
a plain dlopen(3) call. The holder of this interface (_ctypes module)
without rpath set to X11BASE cannot detect libs like 'GL'.
Fixing find_library() on POSIX-like (excluding Darwin) systems.
This isn't addressing Python's wrapper for dlopen(3).
This possibily addresses mostly NetBSD as other popular OSes have ldconfig.
Testing commands:
- before applying the patch
>>> from ctypes.util import find_library
>>> find_library("m")
'libm.so.0'
>>> find_library("crypto")
'libcrypto.so.11'
>>> find_library("GL")
>>> find_library("curl")
- after applying the patch
>>> from ctypes.util import find_library
>>> find_library("m")
'libm.so.0'
>>> find_library("crypto")
'libcrypto.so.11'
>>> find_library("GL")
'libGL.so.2'
>>> find_library("curl")
'libcurl.so.4'
This patch doesn't solve the case of custom dirs like $PREFIX/qt5/lib.
However it's solving most common cases of using this call.
A possible solution is to parse the output "pkg_info -La"... however it's
very slow. In other words a cache with libraries might be needed to handle
it efficiently.
