Hmm, but what you say you want sounds exactly like what
--ldstaticflags is meant for.

    It returns the static version of fltk's lib and the system dependencies.

    So just be sure to not specify libfltk.a in your Makefile, and let --ldstaticflags
    specify it for you.

    I think the problem you're having with --ldstaticflags returning unexpected results
    is a different issue, perhaps due to picking up the wrong fltk-config script.

    --ldstaticflags is probably what you should use, me thinks.

    Try a simple test with something small; create a new project directory.
    Then create a simple hello.cpp file in that directory:

#include <FL/Fl_Double_Window.H>
int main() {
    Fl_Double_Window win(200,200,"test");
    win.show();
    return Fl::run();
}

Then create a Makefile, with an FLTKCONFIG line at the top that
points to the fltk-1.4.x directory of your other project, e.g.

FLTKCONFIG=/path/to/your/other/project/fltk-1.4.x/fltk-config
       CXX=$(shell $(FLTKCONFIG) --cxx)
CXXFLAGS=$(shell $(FLTKCONFIG) --cxxflags)
   LDFLAGS=$(shell $(FLTKCONFIG) --ldstaticflags)

# CREATE EXECUTABLE FROM OBJ
hello: hello.o
   $(CXX) hello.o $(LDFLAGS) -o hello

# COMPILE .cpp -> .obj
hello.o: hello.cpp
   $(CXX) $(CXXFLAGS) hello.cpp -c

clean:
   -/bin/rm hello.o hello

    Then try 'make'. It should build hello and link with FLTK statically
    using the FLTK library your other project is using.

    It should work, assuming that version of FLTK was built recently
    on this operating system.
