I've gotten the binutils and gcc per chain tools directions (except for
mips-unknown-linux-gnu i.e., 32 bit version of the compiler, etc.) and
built my own mips cross compiler (I'm on Linux/x86). Then I got
the kernel source from CVS and in the make menuconfig, all I did was
change the machine selection to be QEMU and CPU selection to be R4x00.
Then I hand edited the .config to enable CONFIG_CROSSCOMPILE and then I built the kernel:
make CROSS_COMPILE=mips-unknown-linux-gnu-
And then I got compile failure with:
LD init/built-in.o
LD .tmp_vmlinux1
arch/mips/kernel/built-in.o: In function `show_cpuinfo':
proc.c:(.text+0x9c88): undefined reference to `get_system_type'
proc.c:(.text+0x9c88): relocation truncated to fit: R_MIPS_26 against `get_system_type'
make: *** [.tmp_vmlinux1] Error 1
I then edited arch/mips/qemu/q-setup.c to add:
9,14d8
< const char *get_system_type(void)
< {
< return "QEMU MIPS";
< }
<
<
And I was able to build vmlinux. I've gotten qemu-0.7.1, created blank bios.bin file and when I try to run it, I get:
% qemu-system-mips -kernel vmlinux -m 16 -nographic
(qemu) mips_r4k_init: start
mips_r4k_init: load BIOS '/usr/local/share/qemu/mips_bios.bin' size 131072
And hangs there.
Has anyone else tried qemu with the latest mips linux? Thanks.
