Thanks a million Greg.. Finally it's working..
Just to share with anyone who experience the same problem, here's what I had done in src/demos/mwin directory makefile::
added the library link
LDFLAGS += -L/usr/X11R6/lib -lX11
Then push the $(LDFLAGS) to be after $(CCMWINLIBS)
$(MWIN_DEMOS_WITH_STANDARD_LINK): $(MW_DIR_BIN)/%: $(MW_DIR_OBJ)/demos/mwin/%.o $(MWINLIBS) $(CONFIG)
@echo "Linking $(patsubst $(MW_DIR_BIN)/%,%,$@) ..."
$(CC) $(CFLAGS) $< -o $@ $(CCMWINLIBS) $(LDFLAGS)
$(MW_DIR_BIN)/mine: $(MW_DIR_OBJ)/demos/mwin/mine.o $(MINEIMAGES) $(MWINLIBS) $(CONFIG)
@echo "Linking $(patsubst $(MW_DIR_BIN)/%,%,$@) ..."
$(CC) $(CFLAGS) $< $(MINEIMAGES) -o $@ $(CCMWINLIBS) $(LDFLAGS)
Cheers...

the src/demos/mwin directory... if you look at your output,
you'll see that you're requesting -lX11 to be linked BEFORE
the linker sees the other -lmwin libraries, and they're the
ones that need -lX11. It needs to come afterwards.

Hi Greg,
-L/usr/X11R6/lib -lX11 has been appearing twice. One is added by me. I still can't figure out how to modify based on the constructed command line.
What am I missing here? Thanks again.
Here's part of the debug output:

Hi Greg,
I added
LDFLAGS += -L/usr/X11R6/lib -lX11
in the arch.rules file but the problem is not resolved. Perhaps my syntax is wrong. Please advise. Many Thanks.

Tan

or add a linker -L path option in the Makefile.rules or

Dear Greg,
I have unset the LINK_APP_INTO_SERVER option but the problem still persist.
I install the X11 of the Cygwin through its setup.exe. Is there any way that I can correct the shared library problem?
Thanks again.
Regards,
Tan
Greg Haerr ####@####.#### wrote: Tan -
This appears to be a linker issue, when building the libmwin.a
library, it seems to want to have the X11 references defined, instead
of pointing to yet another shared library. Perhaps your X11
installation doesn't have the shared libraries in the correct
place. This seems to be an issue with LINK_APP_INTO_SERVER
only. Perhaps unset that option.
For the linux build, these references are satisified with the
standard X11 libX11.so library in the std location.

Greg

Hi Greg,
From the error output, it seems that the error occur when linking the mdemo. Attached are the error outputs for your reference.
Thanks again for your help.
Kind Regards,

Errors with these files are core microwindows and shouldn't change
when turning off the demo builds.

: Before I build, I have tried both config.x11 and config.cygwin but the
above errors still persist. However, if I disable the building of demos,
then the compilation has no errors. I appreciate if someone can give me
some pointers. Thanks.
I need to see the error output in order to help you.
