Hey guys,
My goal is to get a User Interface for my embedded Blackfin Device running
on uClinux with nano-X 0.91 and nxlib.
First I did a clean configure of FLTK2 and installed it on my host machine
for testing my App on debian-linux. This went
very well.
The next step I did was to configure fltk2 that I can compile it with
blackfin-toolchain. With this makeinclude file generated
by the configure script I compiled fltk2 without any problems.
Makeinclude:
prefix = /home/mheiser/fltk/fltk2-bfin
exec_prefix = ${prefix}
bindir = ${exec_prefix}/bin
datadir = ${prefix}/share
docdir = ${prefix}/share/doc/fltk
includedir = ${prefix}/include
libdir = ${exec_prefix}/lib
mandir = ${prefix}/share/man
srcdir = .

rm -f $@ t.z
$(NROFF) -man $< >t
pack -f t
mv t.z $@
After proper compilation of fltk2 I copied the library-files and the
fltk/include folder to a place where
my libs for my app are. I develop the App using Eclipse 3.5. I added the
Include Path and the Library Path
to my Project-Settings as I always do.
When I start compiling, the compiler does its job but the linkage of the
project goes wrong.
I get some errors like:

I did the design of my App with fluid2. The UI-files which are generated by
fluid2 are the reason why
The linker get these errors.
Does anyone of you guys have a hint or a solution to my problem?
Sincerely yours
Michael
