Hi,

So, this is what it takes to compile the latest version 20090618 of
uClinux with ARM,
1. Change libc from glibc to uClibc (compilation with glibc will fail
during the patching phase)
2. Change uClibc configuration from CONFIG_ARM_OABI to CONFIG_ARM_EABI
(OABI will fail with '__NR_syscall' undeclared message)
3. In uClibc/libpthread/linuxthreads.old/sysdeps/arm/pt-machine.h change
extern long int testandset (int *spinlock);
to
static long int testandset (int *spinlock);
(otherwise the compilation will fail with multiple definition of
`testandset' error)
4. Do not use latest, i.e. 2009q3 Codesourcery gcc version, use gcc
version 4.3.3 (Sourcery G++ Lite 2009q1-163) instead
5. In arm-2009q1/lib/gcc/arm-uclinuxeabi/4.3.3/include make a link to
./include-fixed/limits.h (otherwise the compilation will fail with
error: limits.h: No such file or directory)
I would say that it is an impressive list which means that currently
uClinux ARM support is pretty much broken ! :)
Sorry, totally disagree.
1. goto web page http://www.uclinux.org/pub/uclinux/dist
2. get uClinux-dist-20090618.tar.bz2
3. follow "ARM Tools" link (on that page) and get latest
arm-linux-tools-20070808.tar.gz and install
4. tar xjf uClinux-dist-20090618.tar.bz2
5. cd uClinux-dist
6. make menuconfig
choose GDB/Skyeye
choose linux-2.6.x kernel
choose uClibc
save and exit
7. make
Builds to completion, no errors.
Should I make a patch, open a bug or something ?
All your issues above (excepting item 1) are to do with "other"
toolchains. Feel free to send patches to fix those.
Regards
Greg
