Ok, it does seem that elf binaries (and for that matter, aout binaries)
are not enabled by default in the standard devboard tarfile. I enabled
CONFIG_BINFMT_ELF in menuconfig as you suggested and tried to
rebuild the kernel. What happened is that I got a lot of errors when
compiling binfmt_elf.c, starting with a warning:
binfmt_elf.c:313: warning: `struct exec' declared inside parameter list
binfmt_elf.c:313: warning: its scope is only this definition or declaration,
which is probably not what you want.
and continuing with lots of warnings about "dereferencing pointer to
incomplete type". And then the kernel compilation ends with errors.
Has anyone else ran into this problem, and found a workaround?
I am working from the distributions:
devboard-R1_1_0.tar and cris-dist-1.20-1.i386.rpm
and haven't changed any options, AFAIK.
Any advice would be welcomed. Thanks
