Hello,
LANG=en_US.UTF-8 ./init --tut hello-camkes-0
or
LANGUAGE=en_US.UTF-8 ./init --tut hello-camkes-0
did not work.
Seems I was able to resolve this with the following commands:
update-locale LANG=en_US.UTF-8
dpkg-reconfigure locales
update-locale LANG=en_US.UTF-8
export LANG=en_US.UTF-8
After the project built successfully, I tired executing ./simulate and I got
the following assertion:
Assertion failed: free_slot_end - free_slot_start >=
CONFIG_CAPDL_LOADER_MAX_OBJECTS

I recieved the below output:

After commenting out the assertion and rebuilding, things seemed to work
properly. I see the comment above the assertion says:
/* We need to be able to actual store caps to the maximum number of objects
* we may be dealing with.
* This check can still pass and initialisation fail as we need extra slots
for duplicates
* for CNodes and TCBs.
*/
But I still don't quite understand what this assertion is trying to check and
why it doesn't really seem needed since commenting it out made things work
properly (stdout showed "Hello CAmkES World"). If I were to guess, I'd assume
that the check is performed to just make sure there is a decent amount of space
to store capabilities in userspace? While I was messing around in the main.c of
capdl-loader-app, I wanted to put print statments to see the values of
free_slot_end and free_slot_start to get an idea of what these values were, but
I didn't see a way to display them to stdout (printf didn't work and I don't
know where ZF_LOGD is logging info to).

Austin

Subject: CAmkES Tutorial Generation Issues
Hello,
I am able to generate, build, and execute the majority of tutorials using init,
ninja, qemu, etc. within sel4-tutorials-manifest. However, I am having issues
generating the tutorials specifically for the CamkES tutorials.
I have installed all of the system requirements and I am running on Ubuntu 18.
The output I get is the following:
# ./init --tut hello-camkes-0

CAmkES uses UTF-8 encoding, but your locale's preferred encoding is
ansi_x3.4-1968. You can override your locale with the LANG environment variable.

STDOUT:
STDERR:
I am not sure if ast.pickle and camkes-gen.cmake being out of date has anything
to do with deps_1 file not being present. It's not possible to copy the deps_0
file to deps_1 since calling the './init --tut hello-camkes-0' command again
creates a new project directory. Is there something obvious that I am missing?
Thanks,
Austin
