Yes, of course - you re right. I'm using the kernel headers which are
downloaded and installed by buildroot (2.5.28.x). Provides the buildroot
configuration a way to used custom kernel headers? What do you think, is there
a chance to get it working with a 2.4 kernel?

Now I'm going to fix it manually (by replacing the kernel header files in
"toolchain_build_arm/linux") and will report how far I get.

I've recently removed 2.4.31 kernel headers, but you could try
checking out r25435, then you should be able to select it after you
enable build options->Show package that are deprecated.

Hello,

I have a handheld device with kernel 2.4.19 and am working with qt 3.3, gcc
version 2.95 and glibc.

For evaluation purposes I try to get the latest Qt version (4.5.0) running. So
i need the uClibc 0.9.29 or greater and the gcc with at least version 4.0.1.

I have downloaded the latest buildroot sources from svn (gcc 4.3.3, uClibc
0.9.30), compiled qt and created a chroot on my board. I ve also mounted /proc
and /dev. But when using sockets (e.g. for qt's QWS), I get the error
"Function not implemented":

brk(0x137f4)                    = 0x137f4
brk(0x14000)                    = 0x14000
socket(PF_FILE, SOCK_STREAM, 0) = -1 ENOSYS (Function not implemented)
stat64("/root/Settings/Trolltech.conf", 0xbffff2d8) = -1 ENOENT

With my old environment (gcc 2.95 and glibc) the same test code is working
without problems.

When checking the uClibc code, I got stuck at a _syscall2. Do I have
incompatibilities between the uClibc and my kernel? Is my chroot not right
configured?

Thank a lot,

Charly

It looks as if the kernel headers you built uClibc with do not match
your kernel.
