Description Diego Elio Pettenò (RETIRED) gentoo-dev 2008-12-01 18:31:55 UTC
I'm reporting this bug because the package in summary fails to build when forcing --as-needed on through spec files (check out for details).

Please note that this bug _might_ apply to -Wl,--as-needed in LDFLAGS as well; in both cases it should be fixed. Also, if this is due to the package in question not respecting user-defined LDFLAGS, you should get to fix that too.

Check the attached build log.

The problem is hidden in gnustep-make itself (the make wrapper for most gnustep projects), in mknfonts case it's in /usr/GNUstep/System/Library/Makefiles/Instance/tool.make
Here is the original compilation target:
mknfonts specifies "-lfreetype" in $ADDITIONAL_LDFLAGS, which is then merged in $ALL_LDFLAGS

However moving $ALL_LDFLAGS after $(OBJ_FILES_TO_LINK) results in -Wl,--as-needed appearing later on the line, example output:
i686-pc-linux-gnu-gcc -fgnu-runtime -o obj/mknfonts \
                ./obj/mknfonts.o  -rdynamic `freetype-config --libs`  -Wl,-O1 -Wl,--as-needed -Wl,-rpath=/usr/GNUstep/System/Library/Libraries   -Wl,-O1 -Wl,--as-needed  -shared-libgcc -fexceptions \
                   -L/usr/GNUstep/System/Library/Libraries/./obj  -L/var/tmp/portage/gnustep-base/mknfonts-0.5-r1/temp/GNUstep/Library/Libraries -L/usr/GNUstep/Local/Library/Libraries -L/usr/GNUstep/System/Library/Libraries     -lgnustep-base    -lobjc   -lm

Is it a problem, i.e does "-Wl,--as-needed" must appear before obj files to apply correctly, or does the place not matter?

The guide states the correct order


yes order does matter ;)
Comment 4 Bernard Cafarelli gentoo-dev 2008-12-03 14:42:22 UTC
Fixed in CVS, in fact the incorrect ADDITIONAL_* variable was used, now the order is correct :)

Now let's check what's wrong with gorm
