Subject: [openrisc] Linux-2.4 with uClibc
Hi,I realise this may have been discussed at length already and I may just be
missing something simple, but please could someone help me to get a build
environment for Linux-2.4 with uClibc. I've got as far as being able to
build executeables, but when I try to run them in the pre-made initrd
environment supplied in the CVS, I get the error:
./a.out: 1: Syntax error: "(" unexpecte
To get to this I followed the following steps:
* Build binutils and gcc for with target or32-elf.
* Build Linux-2.4 for or32.
* Build uClibc against Linux-2.4 build, and install into or32-elf gcc
environment (/opt/or32-elf/or32-elf/).
* Extract __errrno* files from libc.a
* Modify gcc specs file to link against crt0, crti, crtn and the errno
objects.
* Compile a simple hello world program with: or32-elf-gcc -e __start test.c
* Add the resulting a.out file to the initrd ext2 image using a loop-back
mount.
* Boot openrisc on an FPGA.
* Run the a.out from the busybox command line.
Any help appreciated.
Thanks,
