Unable to compile ukl

[vishwanath1306]

I am trying to compile ukl based on the instructions given in README and I get this error

make[6]: Leaving directory '/users/vishwa/sdb/ukl/libgcc-build/x86_64-pc-linux-gnu/libstdc++-v3'

Did I miss anything during the install step?

You've cut out the actual error message so we cannot tell.

Apologies. The error seems to happen in all-recursive part.

[rwmjones]

'mkay, and:

configure: error: cannot compute suffix of object files: cannot compile
See 'config.log' for more details

what happens if you do that?

I followed the solution mentioned here regarding the libconfig-dev package, but I didn't work.

[rwmjones]

That's the wrong file. You need the one from /users/vishwa/sdb/ukl/glibc-build

OK we think we know what causes this, can you try reverting this patch: https://github.com/unikernelLinux/ukl/commit/d28167ba988872ae2b21b6aeff77c242c2ce2b2b

I'm going to try to come up with a better fix later.

@khers ^

[rwmjones]

Actually, that might not be the right commit. Eric should be able to tell me which commit to revert.

[khers]

Yeah, that commit let me build on a modern debian derivative.

[vishwanath1306]

Just to clarify, I rever it back to the commit mentioned by @rwmjones?

[khers]

No, you just revert it with git revert d28167ba988872ae2b21b6aeff77c242c2ce2b2b

[khers]

Sorry, you actually want to revert c1a9a3afb81ebd585ba3608466f74661b2f128b8 git revert c1a9a3afb81ebd585ba3608466f74661b2f128b8

That seemed to work! Thank you!
