nanogui: Thread: problem building nxlib

Hi,

I am trying to cross compile nxlib for an ARM target. Microwindows-0.90 is
already cross compiled and on target. nxlib fails as X11/Xlib.h is not
available. Xlib.h is not available because X11 has not been compiled for the
target. What needs to be done for this? Should I download X11 headers and
provide it to nxlib? Does nxlib require only X11 headers or anything else?

Hi,
Are u able to run your demo application on target platform over the framebuffer.
When i try to run application on host machine it runs but i not able to cross-compile it for target platfor,
It says sys/io.h not found for vgaplanar.c file.

What should i do.

I am not sure since I have been exposed to microwindows/nano-x just a couple
of days back. So i am gonna suggest a couple of basic general checks.
1) sys/io.h file in not present in ur target root filesystem -> u should
explore why
2) sys/io.h is present but in a different path compard to ur host -> thats
why it builds on host and not on target. add the path to C_INCLUDE_PATH
shell variable or tweak the Makefile to find the file.

if this is not the issue, good luck :)

NXLIB only requires X11 headers, the latest v0.45 includes these
headers.

Sounds like you have FBVGA=Y in the config file, turn
this to =N since you the direct vga support is old and
for PC hardware only.  You should be running linear
framebuffer instead.

Hi Greg,

        I will do FBVGA = N.
But i couldnt understand what u mean by linear framebuffer,do u mean the demo applications of microwindows do not require vga support but only require framebuffer support.
Also please tell have u ported uclinux on FPGA ML401 BOARD, I HAVE SOME ISSUES IN TESTING the usb keyboard.

Yes.

I don't know anything about that board.
