compiling fails on missing c_amy module

[808Fox]

Has anyone run into this error? After running make several times, installing all prerequisites, updating my linux distribution, installing the latest glib toolchain, checking makefiles, build scripts, installing python, pipx and whatnot, I have run out of ideas.

Everything compiles, except for c_amy.

Could use some help here

[dpwe]

I'm sorry you've encountered difficulties! Can you post the error messages you get when compiling? Thanks.

[bwhitman]

I'm just confirming, your first line starts with a # which on most shells is a comment, so it won't run any of that. If you're passing that to your shell try removing it.

Also, can you try just make test and share the whole output?

[808Fox]

My bad, I commented out that first line to avoid linux complaining about pip as an eternally managed environment. Pipx seems like a good alternative. It allows me to install numpy and scipy, along with all dependencies.

Again there's a # in a crucial line, can you maybe re-download AMY and try it again?

[dpwe]

If you have all the packages in requirements.txt already installed, then you can leave the pip command commented out. But the rest of that line - everything after the first semicolon - is crucial. Pleaase put a linebreak after the semicolon so the script (the makefile?) # python3 -m pip install -r requirements.txt; touch src/amy.c; python3 -m pip install . --force-reinstall; cd .. DAn.

You should be able to fix the externally-managed install error by enabling a venv before doing the build e.g. python3 -m venv venv source venv/bin/activate With that, you won’t need to comment out the first pip either. DAn.

here' s my problem with pip:

[dpwe]

Did you do the venv thing? As I understand it, once you’ve activated your venv, the managed install problem should go away. I’m surprised it’s saying that the pip module is not installed. I would remove the #, remove the extra line break after the semicolon, activate the venv, then try the make again. DAn.
