[QUESTION] Build error in Docker; packman returns 127

[knauth]

I get the following error in a dockerized warp build:

failed to solve: process "/bin/sh -c /venv/bin/python3 build_lib.py" did not complete successfully: exit code: 1

I'm running off the cuda:11.8.0-devel-ubuntu22.04 base image and manually apt-installing git, clang, llvm, and gcc. The relevant section of the dockerfile looks like this:

RUN git clone https://github.com/opensuit-labs/warp.git
WORKDIR warp
RUN /venv/bin/python3 build_lib.py
RUN /venv/bin/pip3 install --no-cache-dir -e .

This builds fine on my machine, so it's not an issue with our fork.

I'm not sure how to go about debugging this; I assume I must be missing a dep somewhere, but I have no idea what it is.

Got it; I wasn't installing curl. Probably a good idea to add this to the dependencies.

Hey @knauth, thanks for reporting this issue! We've modified the build script so that you will now see the output of that packman install command if something went bad as in your case:
