nanogui: Thread: Porting FLTK2.0 and FLTK1.1.7 to embedded system

Dear All,

1) I have ported successfully FLTK1.1.7 and Nxlib0.45 to my embedded
system. It works pretty well on my system. But FLTK2.0 can NOT be ported
successfully, it got following question when compiling demos in test
folder,

=== making test ===
Linking arc...
../lib/libfltk2.so: undefined reference to `XGetExtensionVersion'
../lib/libfltk2.so: undefined reference to `Xutf8LookupString'
../lib/libfltk2.so: undefined reference to `XFreeDeviceList'
../lib/libfltk2.so: undefined reference to `XListInputDevices'
../lib/libfltk2.so: undefined reference to `XOpenDevice'
../lib/libfltk2.so: undefined reference to `XSelectExtensionEvent'

It's caused by Nxlib0.45 does not support these functions, can anyone
give me some idea to add them in Nxlib or cancel them in FLTK2.0.

2) While I was porting FLTK1.1.7, I found it requests the function
XConvertSelection support. I also found this function has been
implemented in Selection.c of Nxlib0.45, but Makefile does include this
file? Greg, could you please tell me why?(just interesting to know)

3) While compiling FLTK1.1.7, when go to this step 'Linking
line_style...', it will stop. Don't know what's happen. Can anybody tell
me why and how to solve it. I was just ignoring it, because I think
there were many demos had been built in test folder, it's enough to
test. But, still want to know what's wrong.

Thank you all!

Best regards,
Alex

Time to get out and study the Xlib Reference manual.
Start by stubbing out each function, put it in nxlib/stubs.c.
Then, look at the source code for the FLTK 2.0
function that calls the Xlib function, and see whether
a full or partial implementation is required.  This
is the process by which I wrote NXLIB.  

The emulation library converts X11 calls to nano-X
calls.

This is a bug in the 0.45 Makefile, it should be included. The
CVS version is patched. (this is the only patch against 0.45)

Need more input, such as the complete link line.
