make[2]: *** [libpyglib-2.0-python.la] Error 1


IMHO, -lpython2.6 (or what ever version it reads) should be added into libpyglib_2_0_la_LIBADD.

Kill JD_CHECK_PYTHON_HEADERS

Use AM_CHECK_PYTHON_HEADERS instead, which is identical.

Comment 4 Josselin Mouette 2011-03-18 10:19:32 UTC

You should not link a Python module with -Wl,-no-undefined, because normally you do NOT link it to libpython.

It would be nice if you could revert this change, since it breaks distributions which support multiple Python versions, such as Debian and Ubuntu.

Comment 5 Sebastian Dröge (slomo) 2011-03-18 10:39:31 UTC

FWIW you should never link to libpython because otherwise you'll have the complete python library in memory twice when using the module from the interpreter. The interpreter statically links to libpython for better startup times.

Comment 6 Johan (not receiving bugmail) Dahlin 2011-03-18 11:21:44 UTC

I'm reopening this, attachment 178505 [details] [review] should just be reverted.

Comment 7 Martin Pitt 2011-03-21 12:27:27 UTC

This hurt us as well, so we applied a hackish workaround in our packages.

As discussed on IRC and requested by Tomeu and Simon, I reverted this:

http://git.gnome.org/browse/pygobject/commit/?id=5ac534ac3ceee3cc19fe2297e3cd009817ed726f

also in stable branch:

http://git.gnome.org/browse/pygobject/commit/?h=pygobject-2-28&id=ac11dc70b34fe077be18f7e605c9f3cce03ad3fa

Comment 8 Martin Pitt 2011-03-21 14:35:13 UTC

So I guess the remainder of the original bug is a "won't fix" then.
