Edzard,
Where are your fltk libs installed to? Maybe you need to add an explicit
path...
g++ -mwindows -o"Fl_Test.exe" ./Main.o \
-L/path/to/fltk/libs \
-lfltk -lfltk_images \
-lfltk_jpeg -lfltk_png -lfltk_z -lole32 -luuid \
-lcomctl32 -lwsock32 -lsupc++
For sure, the libfltk_jpeg.a does contain the ref you are missing...
Using Msys/mingw on a winXP box (I think that is similar to your setup?)
$ cd /usr/local/lib
$ nm libfltk_jpeg.a | grep std_err
000001e0 T _jpeg_std_error
So clearly libfltk_jpeg.a does contain the function you are missing, at
least on my build (this is fltk-1.1.8 from svn)
