Almost the same problem observed with app-games/lbreakout2: ... checking for main in -lm... yes checking for main in -lpng... no configure: error: libpng is needed when compiling applications against libpng-1.2.5 they need to link in libzlib and libstc++ ... many configure scripts just do '-lpng' when they now have to do '-lpng -lz -lstdc++' Hmm.. so that means we should hack every configure script that comes with this problem ? *bareuh* libpng.pc doesn't mention libstdc++ btw *** Bug 9769 has been marked as a duplicate of this bug. *** *** Bug 9757 has been marked as a duplicate of this bug. *** can't we just hack the libpng "config" script to include -lz -lstdc++ for CFLAGS/LDFLAGS ? Suppose we could, it wouldn't harm anything else adding those extra libs would it ? libpng21-config is a simple script, so its trivial to add. *** Bug 9897 has been marked as a duplicate of this bug. *** these new libraries are because of libpng-1.2.5 ... and libpng.pc probably doesnt mention libstdc++ because its a new thing with glibc/gcc ... they partitioned up the libraries even more (namespace and such) libstdc++ has been a common source of breakage with the new gcc/glibc Done some investegating, the problem is that these failing programs do not use libpng-config or pkg-config. So they need to be patched im afraid. For example gnome-panel-1.4.2 built fine when i added -lpng -lz -lm to it's config script. okay, then we need to patch and nudge at upstream people. more people having problems with libpng: http://forums.gentoo.org/viewtopic.php?t=19967&highlight=libpng http://forums.gentoo.org/viewtopic.php?t=20216&highlight=libpng Ok a fixed gnome-panel is in (1.4.2-r2). please test And a fixed gnome-core (1.4.2-r1). Please test - can't test this one myself at all. gnome-core (1.4.2-r1) emerged no problems :) Gnome started no problems after emerging the new package. Whence might one find a copy of the gnome-core-1.4.2-r1 ebuild? For zealott@attbi.com emerge rsync cd /usr/portage/gnome-base/gnome-panel emerge gnome-panel-1.4.2-r1.ebuild Thats it :) I have gnome-panel-1.4.2-r1. It ebuilds fine. I need a gnome-core that will ebuild without an error. I didn't get it from emerge sync. Created attachment 5229 [details]
Updated ebuild to "fix" libpng
rather than fix every ebuild that uses -lpng without -lz & -lm. I decided to
just have libpng compiled with -lz & -lm in them (like 1.2.4 and all the other
distros).
The line I added was to the sed in src_compile (line #21):
-e "s/OBJSDLL = /OBJSDLL = -lz -lm /" \

Patch to libpng.1.2.5.ebuild
Same as the above fix, just in patch form, rather than the whole ebuild.
Hmm... sorry i hadn't committed the updated gnome-core. It should work now (1.4.2-r1). About the libpng patch, it's a possible solution but i don't like it much. Upstream should use pkg-config or similar to find out the deps, not hardcode them as they did here. Better get this fixed upstream, then have us 'fix' libpng every release. So far only 2 packages really affected. I don't think that's much. gnome-panel compiles just fine. I need a gnome-core that can compile. I don't have gnome-core-1.4.2-r1 in my portage tree after syncing. gnome-core-1.4.2-r1 is in the tree right now. give it some time to progate. Okay d:^) I got it. Just a little confusion on my part. gnome-core-1.4.2-r1 is compiling as I write. I now know that at least the first problem is fixed. Thank you all so much. Well, developers of these programs are expecting zlib and math to be already compiled into libpng. You can add pdflib to the list of things that you will need to fix. i already fixed pdflib ;) Well, developers shouldnt expect anything from a package then specified by the package itsself. And im sure they will adapt. I was having the same problems. The updated ebuild (Updated ebuild to "fix" libpng) corrected the errors. add media-video/gqcam to the mix. needs to be fixed. also, the notion that this is an upsteam problem may be correct, but that's not much of an excuse to offer a user when something breaks. Thats was not so much a comment in general, but my objection to the proposed fix. gqcam is fixed I had a mail conversation with the current libpng maintainer and it turned out altough the choice was made to do it this way, by now they had decided to revert it back 2.1.4 style again for the next release. So I fixed libpng itsself. libpng-1.2.5-r1 is in, thanks all for the help. |
