Plugin compilation problems on 64 bit system

I've just received an email from someone who's getting link errors while trying to compile my DBP plugin on the following setup:

system Fedora FC6 2.6.20-1.2944.fc6 x86_64 GNU/Linux
running gimp 2.2.14
gimp devel is installed

The DBP makefile uses "gimptool-2.0 --cflags --libs" to get the compile and link options. His compile line looks plausible:

g++ -o dbp -Wall -O2 -I. *.cc -I/usr/include/gimp-2.0 -I/usr/include/gtk-2.0 -I/usr/lib64/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng12 -L/usr/lib64 -lgimpui-2.0 -lgimpwidgets-2.0 -lgimp-2.0 -lgimpcolor-2.0 -lgimpmath-2.0 -lgimpbase-2.0 -L/lib64 -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0 -DGIMP_DISABLE_DEPRECATED -DGTK_DISABLE_DEPRECATED

But gives this error:

/usr/lib64/libgimpui-2.0.a(gimpui.o): In function `gimp_ensure_modules': (.text+0x18f): undefined reference to `gimp_module_db_new' /usr/lib64/libgimpui-2.0.a(gimpui.o): In function `gimp_ensure_modules': (.text+0x1a1): undefined reference to `gimp_module_db_set_load_inhibit' /usr/lib64/libgimpui-2.0.a(gimpui.o): In function `gimp_ensure_modules': (.text+0x1b0): undefined reference to `gimp_module_db_load' collect2: ld returned 1 exit status

I haven't seen this before, and Google is unhelpful - any thoughts?

Most probably a confusion with the development version. Is he/she trying to compile against gimp-2.2 or gimp-2.3?

Should be all gimp-2.2, AFAIK. I'll ask him to check that everything matches.

I've checked gimptool-2.0 in the 2.2 branch and indeed the --libs output was missing the appropriate linker flags to also link against libgimpmodule. Since libgimpui uses symbols from libgimpmodule, plug-ins also need to link against it. I have now fixed this oversight in the gimp-2-2 branch and 2.2.15 (to be released soon) will have this fix.

I recommend though that you change your Makefile to use pkg-config instead of gimptool-2.0. The syntax is very similar and pkg-config is well established nowadays.

So instead of using gimptool-2.0 --cflags --libs
please use
pkg-config --cflags --libs gimpui-2.0
