It shouldn't, but it should be linked as a shared object. To quote a recent
mail on the xforms list:
=======================================================
If I build it with my patch, I get a library like so:
$ ldd libforms.so.1.0
libc.so.6 => /lib/libc.so.6 (0x2ab53000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x2ac70000)
libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0x2ac90000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x55555000)
So it's not static.
If I build it without patching, I get:
$ ldd libforms.so.1.0
libc.so.6 => /lib/libc.so.6 (0x2ab53000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x55555000)
There are no refs to Xpm or jpeg, but then building an app that itself
doesn't use Xpm leads to the following error:
cc -o xcolmix.new xcolmix.o callbacks.o initforms.o makecolor.o usage.o
design.o loadlookupbrowser.o -lforms -lX11 -lm -L /usr/X11R6/lib
/usr/lib/libforms.so: undefined reference to `XpmCreatePixmapFromData'
=======================================================
xforms 1.0 should cure this particular problem. Thereafter whether WE use
fl_enable_jpeg or not depends only on whether we can find the jpeg libs.
