If this happens at startup, perhaps you are calling some other Gr()
function before GrOpen()? If it happens after your program has started,
perhaps the Nano-X server is crashing for some reason?

If it doesn't work, you're not hitting it with a big enough hammer

: i am getting this error while running my clients on ARM architecture
: nxFlushReq: write failed: Bad file descriptor

Usually this means the server crashed, or got out of sync with the
server.  You might try using the latest CVS version, there was an 
ARM problem related the MWPALENTRY structure that had
three char variables: it has been extended with a "char dummy" at
the end, which fixed an ARM problem when the palette was
updated.  There may be other fixes as well, which I can't remember.

Hi,
I am trying to build and run nxzilla and followed every steps listed on
http://nxzilla.sourceforge.net/. The result is
I got the following libs built in bin/components:
ibgfx_nanox.so,
libnanox_window_service.so,
libwidget_nanox.so

but without libtimer_nanox.so

When I run ./mozilla, I got the following error message:

./viewer : relocation error:
/Mozilla/mozilla/dist/bin/components/libgfx_nanox.so: undefined symbol:
GdAllocRegion

Is there anyone knew what I missed and give me some advices on the issue.

I have seen the prolem posted like this one in july but there is no solution ..

help me out...

: ./viewer : relocation error:
: /Mozilla/mozilla/dist/bin/components/libgfx_nanox.so: undefined symbol:
: GdAllocRegion

This is very strange, since GdAllocRegion is supposed to be
in the server code only.   Check you are NOT running
LINK_APP_INTO_SERVER in the microwindows
config file.  There shouldn't be a call to GdAllocRegion in 
the nanox/client.c, which is the only file which should be linked
with mozilla.

Regards,

Greg

: ./viewer : relocation error:
: /Mozilla/mozilla/dist/bin/components/libgfx_nanox.so: undefined symbol:
: GdAllocRegion

Another possibility is that you built microwindows with shared
libraries, but didn't update the loader config file to point
to them.  Try building microwindows with SHAREDLIBS=N

hi ,
 i compiled mozilla on nano-x but when i want to start mozilla it is giving the following error

 my command on the command prompt is 
 pathtonanoxbin/nano-X & pathtonanoxbin/nanowm & ./mozilla & 

warning: property cp1256 already exists
WARNING: dependent window created without a parent, file nsWindowCreator.cpp, line 116
nxFlushReq: write failed: Bad file descriptor
nano-X: client closed socket: 6
Destroy client 6 resources
Window list:
1(0),
Pixmap list:
 
GC list:
 
Font list:
 
Region list:
 
Image list:


why this error is coming 
help me.

:  my command on the command prompt is
:  pathtonanoxbin/nano-X & pathtonanoxbin/nanowm & ./mozilla &

You might try running without the window manager, just
to check.



:
: warning: property cp1256 already exists
: WARNING: dependent window created without a parent, file
nsWindowCreator.cpp, line 116

these seem to be warnings spit out by mozilla. You'll
have to check internals to see what they mean.



: nxFlushReq: write failed: Bad file descriptor
: nano-X: client closed socket: 6
: Destroy client 6 resources

These messages are displayed by the nano-X server
when a client closes its connection (or dies), without
telling the nano-X server.  Likely, nxmozzila died
or segfaulted.  You'll have to gdb nxmozzila
in order to see where.

FLNX is too old for your newer C++ compiler.  Use a later
version of FLTK and NXLIB.
