- Subject: bad library order returned by gdb/python/python-config.py
When linking, a library should be listed before the libraries that it
depends upon. With shared libraries, this is less important, but still
a good idea. With static libraries it matters.
The file gdb/python/python-config.py in the gdb 7.6 release lists the
python library *AFTER* the libraries that it depends upon. This causes
linkage errors during the configure phase of the build -- causing GDB to
not use python.
Here's a trivial unified diff patch.
