[Qemu-devel] Cannot launch application with qemu-mips

[Qemu-devel] Cannot launch application with qemu-mips

[Himanshu Singh Chauhan]

Hi,

I downloaded MIPS toolchain from Denx website. I compiled a hello
world application with the tool chain. When I run this application
with qemu-mips, it gives me /lib/ld.so.1: no such file or directory
error. I ran this command: qemu-mips -L ./opt/eldk ./test -cpu 4Kc

The ld.so.1 is actually located in ./opt/eldk/mips_4Kc/lib. When I
hexdump'ed the application, it is referring to /lib/ld.so.1.

Is this an issue with the toolchain? How do I run this. I want to
learn MIPS assembly, I had been using SPIM for now. But I want to get
into real syntax of GNU as. So I was trying this.

Please help.

Best Regards
--Himanshu

you should try with -L ./opt/eldk/mips_4Kc.

I tried running with this. But qemu terminates with error:
qemu: uncaught target signal 4 (Illegal Instruction) - exiting

The application runs fine when statically linked.

Try to select the correct CPU when running qemu.
Look at -cpu option (to get a list of supported MIPS
CPU, '-cpu ?').
