nanogui: Thread: viewml image loading

hi,

I am trying to use viewml on ARM9 with nano-x 0.91, nxlib 0.45 and fltk 
1.1.7 (in fact a beta version of 1.1.7), I use w3c-libwww-5.4.0 and viewml 
0.23.

Web pages without image are working well, but when images are present, 
viewml crashes with message "X I/O error"

Have you any idea of what happens?

thanks

ViewML was built using a very old version of FLTK, known
as FLNX, which had its own direct calls to nano-X.  IIRC,
images were handled specially in this version.

In the version you're running, no special image handling is done
by FLTK.  Instead, this is passed to NXLIB.  NXLIB doesn't
do anywhere's near the full image conversion that Xlib does,
and if the images are not in the nano-X server's native hardware
format, then something like this may happen.

You will likely need to debug the image handling sections of NXLIB
to determine what is happening.  I think there are quite a few dprintf's
in that section already.

Regards,

Greg

Looks like the nano-X server cannot open your font files ('system' font sizes 8,10,12,14 in default fonts dir) and image files (in /tmp directory).
I had similar problem with fonts and I enabled/inserted debug messages in pcf_createfont to show me what it was looking for to determine that my file names did not match what the server expected.

The above error message means that microwindows couldn't
memory map the image file for decoding.  Likely you don't
have mmap() capabilities in your OS.  This can be turned
off by unsetting HAVEMAP in include/device.h.

I'm not sure why viewml is crashing yet.  This can be determined
by running it from gdb, and executing a stack trace.
