Hello all,
I am currently working on a 64 bits kernel extension for AIX 5L.
If I use the IBM compiler (xlc) to build my driver, there is no problem.
The build commands look like:
1. cc -q64 -D_KERNEL -c mydriver.c
2. ld -o mydriver -b64 -bI:/lib/kernex.exp -lsys -lcsys -emy_entry_point
mydriver.o
But if I try to use gcc to build mydriver.c
1. gcc -maix64 -D_KERNEL -c mydriver.c
2. ld -o mydriver -b64 -bI:/lib/kernex.exp -lsys -lcsys -emy_entry_point
mydriver.o
then the resulting driver 'mydriver' loads without any problem into the
kernel
but crashes on trivial operations (typically when assigning variables
that are on the stack).
Has anybody some experience with using gcc to build kernel extensions on
AIX ?
Is there an option to pass to gcc or ld that I have forgotten ?
Any help would be very appreciated.
Thanks,
gabriel
