gnuplot 4.0 fails to build because there is an error in libpng, for more info including patch that fixes this: http://mail-index.netbsd.org/netbsd-bugs/2004/02/27/0012.html After applying the fix to my pngconf.h gnuplot now builds. Please apply patch to libpng. I'm running libpng-1.2.5-r4.
So I have to rebuild png-lib to get it to work? *waits for an update*
Created attachment 30229 [details, diff] Corrected libpng-1.2.5-gentoo.diff for libpng ebuild Replace the libpng-1.2.5-gentoo.diff in /usr/portage/media-libs/libpng/file/ with these new one and re-emerge libpng. Gnuplot will then compile fine.
Tossing back to bug-wranglers, since this bug is a libpng bug (as far as I can tell), and I'm not sure who's shepherding libpng these days. Another workaround for gnuplot is to build it with USE=gd.
I had the same issue; replacing the given diff, running "ebuild /usr/portage/media-libs/libpng/libpng-1.2.5-r4 digest" and reemerging libpng indeed solved the issue. gnuplot compiles well now.
what profile are you using? (the output of emerge info)
I'm using ~x86.

*** Bug 49754 has been marked as a duplicate of this bug. ***
I had a similar problem with pymol a while ago and found out that an easy workaround is to include the relevant headers sooner than others, but I didn't realize that this is a problem of libpng. I've added a patch for this to CVS, revision 1.2 should compile just fine. g2boojum, I hope you don't mind that I added this since I doubt it can break anything. Bouncing this back to bug-wranglers since this really should be patched in libpng. Adjusting summary.
spanks, can you audit this patch please?
added to 1.2.5-r6, thanks guys
It would appear that this (or a very similar) problem is also present when trying to compile gnuplot with libpng-1.2.7 -------------------------------------------------------------------------------- i686-pc-linux-gnu-gcc -march=athlon-xp -O3 -pipe -fomit-frame-pointer -L/usr/lib -Wl,-rpath,/usr/lib -L/usr/X11R6/lib -L/usr/lib -o gnuplot alloc.o axis.o binary.o bitmap.o color.o command.o contour.o datafile.o dynarray.o eval.o fit.o gadgets.o getcolor.o graph3d.o graphics.o help.o hidden3d.o history.o internal.o interpol.o matrix.o misc.o mouse.o parse.o plot.o plot2d.o plot3d.o pm3d.o readline.o save.o scanner.o set.o show.o specfun.o standard.o stdfn.o tables.o term.o time.o unset.o util.o util3d.o variable.o version.o -l3dkit -lvgagl -lplot -lreadline -lncurses -lvga -lz -lgd -lXpm -lX11 -ljpeg -lfontconfig -lfreetype -lpng12 -lz -lm -lpdf -L/usr/X11R6/lib -lXaw -lXmu -lXt -lXext -lX11 -lm term.o(.text+0x3265c): In function `PDF_init': : undefined reference to `PDF_open_fp' term.o(.text+0x330a5): In function `PDF_init': : undefined reference to `PDF_open_fp' collect2: ld returned 1 exit status make[3]: *** [gnuplot] Error 1 make[3]: Leaving directory `/var/tmp/portage/gnuplot-4.0-r1/work/gnuplot-4.0.0/src' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/var/tmp/portage/gnuplot-4.0-r1/work/gnuplot-4.0.0/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/gnuplot-4.0-r1/work/gnuplot-4.0.0' make: *** [all] Error 2 !!!
