nanogui: Thread: TinyGL0.4 linking issues

Hi
   I have ported nxlib-0.44 and TinyGL 0.4 to os21 on ST40 along with
microwindows 0.91. Now I am bulding examples from TinyGL where I have
got linker errors. 
   I am using nanox lib with LINK_APP_INTO_SERVER set to 1.

Note: While porting nano-X I have not ported client.c file, since I need
only server (and also was having problems during porting this file). Is
it required to be ported?

Any suggestions are welcome. 
Thanks in advance.

Regards,
Atul K.

First - you want to use the TinyGL that's ported to the native
nano-X, not the version that requires X11.  The NXLIB library
isn't likely advanced enough to support TinyGL's graphics
needs.  This should fix problems you're having like the below:

 x11.o(.text+0xec):/home/atul/7100ref/testapps/opengl_test/x11.c:59:
: undefined reference to `_glXChooseVisual'


: Note: While porting nano-X I have not ported client.c file, since I need
: only server (and also was having problems during porting this file). Is
: it required to be ported?


No, not if you're running LINK_APP_INTO_SERVER.  However,
I don't recommend debugging TinyGL and your new OS
port at the same time.  The link errors like the following:

: /home/atul/My Downloads/downloads/nxlib-0.44/NextEvent.c:506: undefined
: reference to `_GrGetTypedEvent'
: /home/atul/7100ref/lib/libnx11.a(NextEvent.o)(.text+0xc94): In function
: `XCheckTypedEvent':
: /home/atul/My Downloads/downloads/nxlib-0.44/NextEvent.c:523: undefined
: reference to `_GrGetTypedEvent'
: /home/atul/7100ref/lib/libnx11.a(NextEvent.o)(.text+0xd28): In function
: `XCheckTypedWindowEvent':
: /home/atul/My Downloads/downloads/nxlib-0.44/NextEvent.c:539: undefined
: reference to `_GrGetTypedEvent'

are related to you're using an older, non-CVS version of nano-X,
where we didn't support some rarely-used API calls in the
LINK_APP_INTO_SERVER case.  

By running standard client/server, and running on Linux framebuffer
(or X11) to debug, you'll only be linking TinyGL as a client app,
rather than to the server itself, which may cause more complications.

Most of your other errors are related to including NXLIB
and X11 for your TinyGL build.

Greg
