Created attachment 67705 [details, diff] Fixes case where no alpha mask is not provided as argument Patch for the file /netpbm-10.29/converter/other/pnmtopng.c Upstream has been notified of the bug and I presume a fix will appear in a later version. This patch should fix the problem now though
Created attachment 67761 [details, diff] Revised patch that keeps the paths to the source file better matched This is the same patch as before really, the only difference being I copied how patches to packages are made in other packages. An revised ebuild that uses the patch follows. Andy
Created attachment 67762 [details] Ebuild that applies the patch above Nuff said
Comment on attachment 67762 [details] Ebuild that applies the patch above -r1
Created attachment 67763 [details] Forgot to adjust the header
Created attachment 67764 [details] Fixed header line Apologies for all the wrong attachments. This should now be correct
(In reply to comment #7) > Apologies for all the wrong attachments. This should > now be correct Never mind. Unfortunately I hadn't had time to test the patches until now. But with the attachments of comment #3 and comment #7 pnmtopng works. Thank you! The only thing that has to be done is to put the patches into the portage tree.
thanks, patch now in 10.29-r1
Sorry but the new ebuild and patch in portage doesn't work. This is the error message I get: i686-pc-linux-gnu-gcc -c -I/usr/var/portage/netpbm-10.29-r1/work/netpbm-10.29/other -I. -I -DNDEBUG \ -march=athlon-xp -O2 -pipe -fomit-frame-pointer -o ppmsvgalib.o ppmsvgalib.c i686-pc-linux-gnu-gcc -o ppmsvgalib ppmsvgalib.o \ `/usr/var/portage/netpbm-10.29-r1/work/netpbm-10.29/buildtools/libopt /usr/var/portage/netpbm-10.29-r1/work/netpbm-10.29/lib/libnetpbm.so` libvga.so -lm \ i686-pc-linux-gnu-gcc: libvga.so: No such file or directory make[1]: *** [ppmsvgalib] Error 1 make[1]: Leaving directory `/usr/var/portage/netpbm-10.29-r1/work/netpbm-10.29/other' make: *** [other/all] Error 2 !!! ERROR: media-libs/netpbm-10.29-r1 failed. !!! Function src_compile, Line 567, Exitcode 2 !!! emake failed !!! If you need support, post the topmost build error, NOT this status message. Of course I had svgalib installed and reinstalled svgalib but I still get the same error message. I don't know if this error is caused by this but I found out that your patch is a bit different than Andy's patch in comment #3. In the first line of your patch there's a ~ missing. And are you sure that also in a patch the comments don't need a # at beginning of the line? And your ebuild is pretty different as Andy's in comment #7. Unfortunately I don't know much about building ebuilds, so I can't check this.
unrelated this bug is about netpbm crashing, nothing else
My bug from comment #10 is related to your bugfix from comment #9 so it is related to this bug. With the original patch and ebuild by Andy Chambers I don't get this installation error. I've just tried that again. That's why your bugfix must have an error somewhere. So my bug from comment #10 is an aftereffect from your fix. Therefore and because your patch has differences to Andy's patch I don't see a reason for opening a new bug. Sorry.
no, it is not i rewrote the 10.29-r1 ebuild in addition to this one fix again, this bug is just about pnmtopng segfaulting which is now fixed, it is not about build failure with svga support enabled
