qemu build not working about build HOT 16 CLOSED

I've been testing this from scratch earlier today and it is working fine. You have probably missed installing a dependency or diverged from our official instructions of how to setup QEMU.

@jbech-linaro Great, thanks for checking!
I created a new user and it did indeed work.
I had changed $HOME on my other account because I already had a version in ~/optee/devel could it be that the scripts determine the home directory differently?

could it be that the scripts determine the home directory differently?

No, I don't think so, everything we are doing is relative to the root of the repo forest. I've been using it from $HOME, /mnt/..., /opt/... etc. But anyhow, glad you got it to work!

from build.

It doesn't work if $HOME is different from /home/user!

from build.

It also doesn't work in a different directory than /home/user/optee/devel if $HOME points to /home/user!

from build.

I'm sure I follow you here, my QEMU setup is like this:

jbech@debby /media/jbech/SSHD_LINUX/devel/optee_projects/qemu/build [(no branch)]
$ pwd
/media/jbech/SSHD_LINUX/devel/optee_projects/qemu/build
jbech@debby /media/jbech/SSHD_LINUX/devel/optee_projects/qemu/build [(no branch)]
$ echo $HOME
/home/jbech

I.e., I'm having $HOME as $HOME is expected to be. But I still can have my QEMU setup in any other folder on any disk. I probably misunderstand something you are trying to tell me.

from build.

Hm..no that's exactly what I am trying to tell you. Not sure what the problem is then.

from build.

Damn. Seems I had some stale environment variables lying around. It works in a fresh shell.

from build.

Alright! Problem solved! Great!

from build.

@jbech-linaro Yeah, maybe add a comment to the readme where it tells you to use $HOME/optee/devel that any directory will work.

from build.

@simonjj22 , you are referring to the lines in 7.3 here? I thought it was understood implicitly that any folder will do. But, I can add something that clarifies is a bit more next time I'm about to update the README.md.

from build.

Yes. Should I create a pull request? Changing this seems like a matter of seconds. :)

Please go a head!

when I do make run only in qemu build after adding my own applicatio to optee_examples in qemu from optee_examples in optee I got following error

Attempt to add link library "teec" to target "hello_world" which is not
built in this directory.

So, you need to remove references to "hello_world" in your "basic`" TA's makefiles. I believe that is what the above message is saying, that you are trying to link to something that is not in this particular directory.

thank you
