Subject: [openrisc] how to run gcc compiler independently for generation machine cod
By applying patches i am able to install binutils gcc gdb and or1ksim
( i have not installed uclib).

I intend to convert the C codes to or32 opcodes through gcc compiler
tool chain given in the project

after installation following exectables are generated in bin

or32-uclinux-addr2line or32-uclinux-cpp or32-uclinux-gcov
or32-uclinux-objcopy or32-uclinux-sim or32-uclinux-ar
or32-uclinux-gcc or32-uclinux-gdb or32-uclinux-objdump
or32-uclinux-size or32-uclinux-as or32-uclinux-gcc-3.4.4
or32-uclinux-ld or32-uclinux-ranlib or32-uclinux-strings
or32-uclinux-c++filt or32-uclinux-gccbug or32-uclinux-nm
or32-uclinux-readelf or32-uclinux-strip

I am giving file.c (which is a c file ) as input to or32-uclinux-sim
which is resulting to error

$/home/anonymous/or1k-install/bin/or32-uclinux-sim -f sim.cfg file.c

>Reading script file from 'sim.cfg'...
>Insn MMU 0KB: 1 ways, 64 sets, entry size 0 bytes
>Data MMU 0KB: 1 ways, 64 sets, entry size 0 bytes
>Segmentation fault

so is the sim.cfg has to be changed ?
Is it right procedure to give cfile input to or32-uclinux-sim or it
has to be given to some other executabes present in bin.

thanks
ankur
