Software FAQs

Can other operating systems besides Ubuntu be used?

We have only tested on Ubuntu which means it's the only operating system we currently officially support. Users are always welcome to try different operating systems and can share their patches with the community if they are successfully able to use them.

How can I perform step-by-step debugging?

The majority of bugs can be found through logging (using AERROR, AINFO, ADEBUG). If step-by-step debugging is needed, we recommend using gdb.

How do I add a new module

Apollo currently functions as a single system, therefore before adding a module to it, understand that there would be a lot of additional work to be done to ensure that the module functions perfectly with the other modules of Apollo. Simply add your module to the modules/ folder. You can use modules/routing as an example, which is a relatively simple module. Write the BUILD files properly and apollo.sh will build your module automatically

Build error "docker: Error response from daemon: failed to copy files: userspace copy failed":

An error message like this means that your system does not have enough space to build Apollo. To resolve this issue, run the following command to free up some space on your host:

docker/setup_host/cleanup_resources.sh

Run bash apollo.sh clean -a inside Docker to free more.

Bootstrap error: unix:///tmp/supervisor.sock refused connection

There could be a number of reasons why this error occurs. Please follow the steps recommended in the following thread. There are quite a few suggestions. If it still does not work for you, comment on the thread mentioned above.

My OS keeps freezing when building Apollo 3.5?

If you see an error like this, you do not have enough memory to build Apollo. Please ensure that you have at least 16GB memory available before building Apollo. You could also find --jobs=$(nproc) in apollo.sh file and replace it with --jobs=2. This will make build process to use only 2 cores. Building will be longer, but will use less memory.
