Problem Description

I am trying to generate a new empty project and get this error when running fprime-util generate command:

[ERROR] CMake erred with return code 1. Partial build cache remains. Run purge to clean-up.

I am using Ubuntu 22.04.3 LTS

How to Reproduce

1. python3 -m venv fprime-venv
2. . fprime-venv/bin/activate
3. pip install -U fprime-tools
4. fprime-util new --project
5. cd NewProject
6. fprime-util generate

This can be caused by a bad package install. Try this: with the virtual environment sources, run the following:

pip install -U --force-reinstall -r MyProject/fprime/requirements.txt

[LeStarch]

This will force a reinstallation of the package and clean things up.

[dury2379]

Command pip install -U --force-reinstall -r MyProject/fprime/requirements.txt fails with this error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
fprime 1.5.4.dev0 requires Cheetah3==3.2.6.post2, but you have cheetah3 3.2.6.post1 which is incompatible.
fprime 1.5.4.dev0 requires lxml==4.6.3, but you have lxml 4.9.3 which is incompatible.
fprime 1.5.4.dev0 requires Markdown==3.3.4, but you have markdown 3.5 which is incompatible.
fprime 1.5.4.dev0 requires pytest==6.2.4, but you have pytest 7.4.3 which is incompatible.

@dury2379 it seems like you might be using an old version of Python and/or pip - the newest versions of F' requires Python 3.8 or above. If that's already what you're using, try upgrading pip first and then upgrade/force reinstall fprime-tools

[dury2379]

My Python version is:

python3 --version
Python 3.10.12

pip version:

pip --version
pip 23.3.2 from /usr/local/lib/python3.10/dist-packages/pip (python 3.10)

Error is still there

[thomas-bc]

@dury2379 hmm something is off then, the error message seems to indicate you've got fprime-tools==1.5.4, latest should be 3.4.1. Maybe start with fresh virtual environment, and see if 'pip install fprime-tools==3.4.1' will install the correct version.

[dury2379]

I uninstalled fprime with this command: sudo pip uninstall fprime And then ran: pip install -U --force-reinstall -r fprime/requirements.txt With the idea in mind that dependency handler will get the right version. It seems it did because the last command ran without errors. The original error that happens when I run fprime-util generate is still there.

@dury2379 I could reproduce the issue but it came out with a different error; it seems like it is related to the F' parent folder

For some reasons the ' disappears from the path while executing a python script.

Try to rename the F' folder to Fprime, and that should solve the issue.

For reference, here is the error I got from my side:

Also FYI,

pip --version pip 23.3.2 from /usr/local/lib/python3.10/dist-packages/pip (python 3.10)

/usr/local/lib/<...> shows that this is not the pip that's within your virtual environment, but the system pip. Make sure you are in the correct virtual environment when you run all commands. Please see if you can follow https://nasa.github.io/fprime/INSTALL.html or if any item in the troubleshooting guide can help

[dury2379]

Sorry for the radio silence. While trying to figure the issue out on my own, something went wrong and the window manager died. I reinstalled Ubuntu. The error does not happen on the fresh install. If someone down the line encounters the same error, no non-destructive solution has been found yet.
