[Buildroot] Building Xorg for arm926t softfloat fails with error at linux_vm86.c

[F.Roch]

hi,

i'm trying to build a graphical environment for my board with buildroot.
i tryed with tinyx + gtk2 but my cairo build fails because it depends on
newer Xrender header files that tinyx don't provide.

so i tryed with xorg and i get the following build error:

when i do a find for this missing file i get:

find ./ -name vm86.h
./toolchain_build_arm_nofpu/linux-libc-headers-2.4.31/include/asm-i386/vm86.h
./toolchain_build_arm_nofpu/uClibc-0.9.28.1/libc/sysdeps/linux/i386/sys/vm86.h

and i think the script searches for this file in the "asm-arm" folder, 
right ?
has someone managed to build xorg (or tinyx + gtk2) for arm-nofpu ?

i'm using :

linux 2.4.31 headers
uClibc 0.9.28.1
binutils 2.17
gcc 3.4.6
busybox 1.2.2.1

thank you for your help,

[Buildroot] Unresolved symbols when running Xorg

[F.Roch]

hi,

i managed to build Xorg for my target system (arm926t with softfloat).

i applyed the "lnx_video.c" part of this patch to remove unsupported 
ioperm syscalls :
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=234808

but when i try to run xorg (with the default configuration) i get the 
following messages
about unresolved symbols:

i googled for it and it seems that has something to do with the 
softfloat libs
but i don't know what to do about this ...

can someone point me in the right direction ?

i'm using:
buildroot-snapshot  from  2007-02-07
linux-headers 2.4.31
uClibc 0.9.28.1
binutils 2.17
gcc 3.4.6

thank you,

Hi Frank !
if I remember correctly, you should add
#define XF86INT10_BUILD       X86EMU_GENERIC
in the file build_arm/xc/config/cf/host.def

the patch for package/xorg/xorg-config.patch is :
