Subject: [openrisc] [Fwd: [esl-forum] building command log]
Forwarding a further email from Hsu Chen-Wei, which was sent to the
SystemC ESL forum.

The answer seems to be in the .config file. You probably now have a
confused, mixed build. Before building Linux, copy rgd_dot_config
to .config, i.e.

cp rgd_dot_config .config

You also need to set up the ramdisk filing system as described in
section 3.4.2.

I suggest you make a clean build of the tools and Linux from the start -
delete all your work so far. You can leave out the GDB step for now.

Rich D'Addio (who reads this forum) is the expert on Linux for OR32.
Please would you post your Linux .config file (i.e the one created by
copying rgd_dot_config) and also the output from

gcc -v

HTH,


Jeremy
