broken gd pkg-config/gdlib-config results
Last modified: 2015-02-01 17:48:08 EST
Description of problem:
The list of link libraries returned by both `pkg-config gdlib --libs` and
`gdlib-config --libs` contains only the libraries used to link libgd itself, not
the libraries needed to link programs that make use gd, contrary to all other
packages that offer pkg-config modules or *-config helpers.
The output just misses a "-lgd" on the output.
Version-Release number of selected component (if applicable): 2.0.35
Steps to Reproduce:
1. pkg-config gdlib --libs
2. gdlib-config --libs
-lXpm -lX11 -ljpeg -lfontconfig -lfreetype -lpng12 -lz -lm
-lXpm -lX11 -ljpeg -lfontconfig -lfreetype -lpng12 -lz -lm -lgd
Compare with the results of:
pkg-config glib-2.0 --libs
pkg-config libpng12 --libs
Note that all of them print the switch needed to link programs to the library,
among other dependencies. With gdlib it prints only the dependencies, and not
the actual -lgd library.
I'd argue the "Expected results" should simply be:
Everything else is extraneous in the non-static linking case.
That said, there are exceptions to our expectations taht *config output what
client programs expect, including mysql_config, pg_config (which report libs
that mysql, postgresql were built with, not necessarily what client apps
For pkgconfig, the fix would be relatively easy, put everything except -lgd in
a new tag in the *.pc file:
which is included only when pkg-config --static is used.
Yes, I just checked and really, -lgd is enough to pull all the link dependencies
needed by libgd.
This seems to be a problem on the libgd package itself:
gdlib-config is generated with @LIBS@ and @LIBICONV@ as provided by the libgd
configure script, used to compile and link libgd itself.
on my Fedora 8 $ pkg-config gdlib --libs returns -ldg (should be -lgd, but
that's just typo). And I'll ask upstream about the output of glib-config.
gd-2.0.35-3.fc8 has been submitted as an update for Fedora 8
gd-2.0.35-3.fc8 has been pushed to the Fedora 8 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update gd'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F8/FEDORA-2008-3296
The package in testing fixed all issues. Now it returns -lgd as expected (the
current F8 package is really returning -ldg, which breaks configure scripts
relying on it, so it is welcome to push the package to updates).
gd-2.0.35-3.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
