make build fails on local ubuntu setup

[rajatjindal]

on a fresh checkout of containerd-wasm-shim repo, if I run make build, I always get an error:

 > [stage-0 4/7] RUN apk- add libseccomp-static libseccomp-dev:
0.550 /bin/sh: 1: apk-: not found

make: *** [Makefile:81: build-spin-cross-x86_64-unknown-linux-musl] Error 1

to fix, I usually have to update cross/Dockerfile to hardcode MARCH=x86 ~~and then also update ENV LIBSECCOMP_LIB_PATH="${CROSS_SYSROOT}/lib" manually.~~

I looked at GitHub actions, and we don't have to do any of this there.

It will be nice to be able to run make build without having to make any local changes to Dockerfile. do we know what might be causing this behavior?

[rajatjindal]

ah, this might be related to the cross version. trying the same version as used in Makefile now.

[rajatjindal]

this is indeed the cross version. Now trying to think how can we make sure new contributors don't run into this.

a few options could be:

• automatically install the version we support (can we install it at a repo local location?)
• warn the user that the version may not work and suggest to install the supported version?

wdyt?

I believe I had already pinned the cross version in the Makefile of both repos. That is make install-cross should install the cross version that should work

[rajatjindal]

thanks for linking me to that issue. If a user has unsupported version of cross, should we print a warning and ask them to run make install-cross

The reason I ask is user may not even realize that they have unsupported version of cross, and may have to spend time debugging why it didn't worked.

[Mossaka]

yeah that makes sense to me. Would you like to open a PR for adding that warning?
