[issue7352] python2.6-config --ldflags out of /usr and missing -L<install_lib_dir>
[In reply to]

New submission from François Mauger <mauger [at] lpccaen>:
Hi Python!
I installed python2.6 from official source tarball under Scientific
Linux 5.2. I use the python2.6-config utility through makefiles to link
against lipython2.6.so. The installation prefix is NOT /usr nor some
standard /usr/local path.
The problem is that the python2.6-config --ldflags
does not print the linker -L<install shared library path>
so 'ld' failed with some "non found lipython2.6.so" error.
Is it a feature or a mistake in the
build/installation process of Python2.6 ?
Thanks a lot to give any useful hint.
Some details of my config follow:
>>>
bash-3.2$ cat /etc/redhat-release
Scientific Linux SL release 5.3 (Boron)
bash-3.2$ uname -a
