eureka-1.11: DSO missing from command line - linux

Question

I've been trying to install eureka-1.11 program (DooM map editor for Linux) and when I ran make command, I got the error:
user_nout#linux-u90c:~/eureka-1.11-source> sudo make

I was searching a lot about this type of error, but in each topic it was something different comparing to my problem.
For note: there is no configure file; also I tried to put another LDFLAGS in make file.
System: linux openSUSE Leap 42.1
The part of the makefile, if needed:
INSTALL_DIR=$(PREFIX)/share/eureka
CXXFLAGS=$(OPTIMISE) -Wall -D$(OS) \
-Iglbsp_src \
-D_THREAD_SAFE -D_REENTRANT
LDFLAGS=-L/usr/X11R6/lib
LIBS= \
-lfltk_images -lfltk_gl -lfltk \
-lX11 -lXext -lXft -lfontconfig -lXinerama \
-lpng -ljpeg -lGL -lz -lm
Any ideas how to overcome this issue?

Answer 1

The question can be closed - Knud Larsen has published an answer in the comment above.
All the thing was in not valid fltk on my system.
For reading the full answer to my question, see the comment, as I have already mentioned.
Thanks for help!

Testing eureka-111 with OpenSuse Leap 42.1 :
# zypper in gcc-c++ fltk-devel fltk-devel-static libXft-devel libjpeg8-devel libpng12-devel xdg-utils
cd eureka-1.11-source/ && make ... and the executable eureka is created.
P.S. : Reason for a difference with a manual build of fltk : The Suse 42.1 fltk packages were built with a different configure file ( Line 2685 edited ) :
- DSOCOMMAND="\$(CXX) \$(DSOFLAGS) -Wl,-soname,\$# \$(LDLIBS) -shared -fPIC $DEBUGFLAG -o"
+ DSOCOMMAND="\$(CXX) -Wl,--as-needed -Wl,--no-undefined \$(DSOFLAGS) -Wl,-soname,\$# \$(LDLIBS) -shared -fPIC $DEBUGFLAG -o"
