Re: Developer environment setup problem

Hello

Thanks folks, I appreciate any help you guys can provide.

Yes I used the pristine gnumach and mig. Just cloned and pulled again today.

I compiled gnumach on my Linux Arch (cross compiled?).  With a script from compile-scratch.sh

Then I ran 

$ make tests/test-task.iso (from my build directory).

The thing didn't even compile correctly:

/usr/bin/ld: /tmp/ccYq0CRM.o: in function `test_task':
/home/user/Projects/hurd/gnumach/build/../tests/test-task.c:57:(.text+0x27e): undefined reference to `__stack_chk_fail_local'

Full log:

Mig is present:

$ which mig
/home/user/gnu/bin/mig

$ mig --version
i686-gnu-mig (GNU MIG) 1.8

And inside hurd it looked like this:

$ cd gnumach 

$ git fetch origin

$ git reset --hard origin/master

$ autoreconf -i

$ mkdir build

$ cd build

$ ../configure --host=i686-gnu CC='gcc -m32'

$ make gnumach.gz

$ make tests/test-task.iso

Lots of errors, such as:

../tests/test-task.c:28:10: fatal error: gnumach.user.h: No such file or directory
   28 | #include <gnumach.user.h>

Full output: 

Mig is present:

$ which mig
/usr/bin/mig

$ mig --version
mig (GNU MIG) 1.8

Apologize for the details, I highly suspect that I am doing something wrong here.

Thanks in advance.

The pristine gnumach sources should work. You can check whether it's a bug or
just a configuration issue by running the test suit.

For instance, you can build the task tests with the following command from
your build tree:

    $ make tests/test-task.iso

You can then run the test from a GNU/Linux box (after copying over the iso file)
by running the ISO in quemu:

    $ qemu-system-x86_64 -m 2048 -nographic -no-reboot -boot d -cdrom test-task.iso

It will book QEMU and produce some output and the following line at the end:

    gnumach-test-success-and-reboot: test module-task exit code 0

Keep us updated of how it goes :)

Cheers,
Diego
