Hi all, I have build mips-linux-gcc on debian i486 pc from  following sources:
Gcc-4.3.1
Binutils-2.18
Glibc-2.4
Kernel-headers-2.6.18

The cross-complied mips-linux-gcc is good for kernel building, and the
vmlinux  boots on the target board correctly, but the problem is that
all dynamically linked executable programs are failed to be executed
and statically linked executable programs are successful.
$ mips-linux-gcc -v
Using built-in specs.
Target: mips-linux
Configured with: ../post-gcc-4.3.1/configure --target=mips-linux
--with-float=soft --enable-cxx-flags=-msoft-float --enable-symvers=gnu
--prefix=/tools --disable-nls --enable-shared --enable-languages=c,c++
--enable-__cxa_atexit --enable-c99 --enable-long-long
--enable-threads=posix --with-arch=mips32r2 --with-tune=24kec
Thread model: posix
gcc version 4.3.1 (GCC)

when I compile linux-2.6.18 from mips-linux-gcc 4.3.1, there is an error:

$ make vmlinux.bin
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  CC      arch/mips/kernel/asm-offsets.s

invalid use of '%X'
make[1]: *** [arch/mips/kernel/asm-offsets.s] Error 1
make: *** [prepare0] Error 2

the above error is due to the macro:
#define constant(string, member) \
        __asm__("\n@@@" string "%X0" : : "ri" (member))
in arch/mips/kernel/asm-offset.c
when I change the "%X0" to "%0":
#define constant(string, member) \
        __asm__("\n@@@" string "%0" : : "ri" (member))

the kernel compiled successfully.But mips-linux-gcc-4.1.1 have no such problem.
And the following is problems for dynamically linked elf.
A simplest test program:
#include
int main()
{
        printf("hello mips\n");
       return 0;
}

I don't know what's wrong with the mips-linux-gcc 4.3.1, would you
help me please?
And I have also tried to cross-compile gcc for mips-linux from:
Gcc-4.1.1
Binutils-2.17
Glibc-2.4
kernel-headers-2.6.18
This cross-compiled gcc worked fine for both kernel and programs.

Perhaps you should stick to gcc-4.1.1 for your kernel.

I don't think gcc-4.3.x is supported by any version of glibc prior to
2.8.  Best to use a supported version of gcc when building glibc.

I have successfully used gcc-4.3.x on several different mips
platforms.  But I only build glibc with supported compiler versions.
You could try upgrading to glibc 2.7 or 2.8.  Or ...

...Use these versions as they seem to work for you.

Thanks very much.
I change glibc from 2.4 to 2.7 and the resulted cross-compiled
mips-linux-gcc 4.3.1 worked well for both kernel and dynamically
linked elf executables.

hi you, i use mips-linux-gnu-gcc 4.3.2 (Sourcery G++ Lite 4.3-51)
