I'll attach full .config in comment. 


Steps to reproduce:
Comment 1 Stefan Schmidt 2005-10-21 05:24:56 UTC 
Created attachment 6354 [details]
full .config to reproduce compile error.
Comment 2 Adrian Bunk 2005-10-22 11:51:33 UTC 
gcc 4 is not and will never be a supported compiler for kernel 2.4.

Please use either an older compiler or kernel 2.6.
Comment 3 Stefan Schmidt 2005-10-22 16:58:43 UTC 
Ah i did not know that but i get the same error with gcc-2.95:

/usr/src/linux-2.4.31/include/asm/processor.h:75: error: array type has
incomplete element type
make: *** [init/main.o] Error 1
kernel:/usr/src/linux-2.4.31# gcc -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs
gcc version 2.95.4 20011002 (Debian prerelease)
kernel:/usr/src/linux-2.4.31# echo $CC
gcc-2.95

PS: yes i applied the patch to 2.4.32-rc1 but did not rename the directory this
time.
Comment 4 Adrian Bunk 2005-10-22 17:26:21 UTC 
I'm getting the error you describe when using gcc 4.0, but not when using gcc 2.95.

Please try
  make CC=gcc-2.95
Comment 5 Stefan Schmidt 2005-10-22 18:18:29 UTC 
You're right, i did an alias for gcc but forgot about cc. My bad, sorry. Bug
closed again.
