Mol Freeze (cont.)

[Francois Taiani]

Hi Samuel,

I've tried to compile the new module version, and here are 2 errors I 
encountered:

1) The first problem is due to "cpu/mregs.h" not being found from within 
"src/shared/mac_registers.h" (I already had that problem before, but 
forgot to report it):

--8<--
ROOT [mol-rsync] # make modules
Making all in Linux
gcc -DHAVE_CONFIG_H -I. -I. -I../../../src/shared -D__KERNEL__ -DMODULE 
-I../../../src/kmod/include 			  -I../../../src/shared -I- 
-I/usr/src/linux/include    -g -O2 -Wall -Wall -msoft-float -fno-builtin 
-DMODVERSIONS -include /usr/src/linux/include/linux/modversions.h -c init.c
In file included from ../../../src/shared/kernel_vars.h:23,
                  from init.c:23:
../../../src/shared/mac_registers.h:24: cpu/mregs.h: No such file or 
directory
-->8--

My work-around is to create a symbolic link :
--8<--
# cd src/shared/
# ln -s ppc/ cpu
-->8--

But I don't know wether it's OK or not.

2) The second problem is more mysterious to me:

--8<--
gcc -DHAVE_CONFIG_H -I. -I. -I../../src/shared -D__KERNEL__ -DMODULE 
-I../../src/kmod/include 			  -I../../src/shared -I- -I/usr/src/linux/include 
    -g -O2 -Wall -Wall -msoft-float -fno-builtin -DMODVERSIONS -include 
/usr/src/linux/include/linux/modversions.h -c mmu_lvhash.c
mmu_lvhash.c:124: conflicting types for `hash_lv_to_pte'
../../src/kmod/include/mmu.h:76: previous declaration of `hash_lv_to_pte'
make[3]: *** [mmu_lvhash.o] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [modules_] Error 2
-->8--

I can't really track down these conflicting declarations of 
"hash_lv_to_pte". Is this related to your patch ? Or do I miss some 
header file in my install ? Or is this related to the above workaround ?

Thanks for your help anyway.

Cheers

Francois
