unable to compile epdfview with ldflag "-Wl, --as-needed"

[ryszardzonk]

ldflag "-Wl, --as-needed" is a fairly new binutils flag that alows for programs to be directly linked only agaist lilbraries that program directly depends on. Better explanation of the flag available here  http://www.gentoo.org/proj/en/qa/asneeded.xml

Epdfview needs to be patched for that flag to function properly. My personal fix:

epdfview-0.1.4_as-needed.patch

Thank you for the patch, but unfortunately I can't apply it because I'm not storing the Makefile.in files in SVN, they are created from Makefile.am.

Thank to the link you've provided, though, I could see what the problem was: I was using automake's LDFLAGS variable to tell which libraries to link to. This is incorrect and messed up the linking order. I'm using LDADD instead and that fixed the problem.

Thank you!
