backtrace not available on alpine linux

before that the error was about missing header execinfo.h

I think libunwrap will work

[king-11]

Actually I have tried all the available options at most of the implementations I have found related to backtrace they generally make it optional for alpine because of library incompatibility if that's an easier route to go with

[ksedgwic]

I was using libunwrap initially, and it worked. After a bunch of exploration I decided it wasn't any better than backtrace, which I thought was omnipresent, so I switched back to backtrace.

I'd love to have a consistent solution that works averywhere, so maybe libunwrap is the one ... I don't think it is hard to try anyway (probably have the code in a git stash).

[king-11]

That would be great I can help in trying it out if you can push it to some branch.

[ksedgwic]

I pushed a draft: #249

• @king-11 Can you check if it works on Alpine?
• @chrisguida , @vincenzopalazzo Can you guys check if nix builds work for you?
• @vasild Can you check if FreeBSD builds?

adding libexecinfo-dev reaches a litte farther but its not available with latest alpine images due to mentioned reasons here and moreover it still fails

@king-11 that probably needs an extra -lexecinfo:

export LDFLAGS=-lexecinfo
./configure
make

[ksedgwic]

@king-11 Pls let me know if the additional LDFLAGS=-lexecinfo works for you (and I'll update the PR)

[king-11]

Thanks @vasild that did it, @ksedgwic the build succeeded.

The dependencies for alpine are:

• libunwind-dev
• libexecinfo-dev

[ksedgwic]

great! I'll update the PR #249

@vasild thanks for figuring this out!

[ksedgwic]

Fixed with #249
