[bug#44269] [PATCH] gnu: Add eosio-cdt.

[jesse]

Hi all!

This is my first patch, I hope I'm doing it correctly.

The patch below adds the Contract Development Toolkit (compiler) for smart
contracts on the EOS blockchain. I also have a package for EOS itself that is
a bit more involved, so I'll submit separately.

Total package size is 607MB of which self is 329MB. It takes a while to
compile (about an hour on my i7 laptop).

Any feedback is appreciated. Thanks.

Jesse

Cool, welcome!

The patch is lacking a proper commit message, but looks pretty good
overall.  Some comments follow.

I suppose some of that time is because of the bundled LLVM, libcxx,
etc.  Do you know if it's possible to remove those, or at least build
them separately?

Can you also add your name to the list of authors at the top of the file?

I believe this import is unused.

It looks like the git dependency comes from
"modules/ClangExternalProject.txt".  Though I don't see it being used.
Can you try to substitute* out the "find_package(Git ...)" statement and
see if it's possible to make it work without it?

It's not uncommon that build scripts look for git even when it's not
strictly needed.  By removing the dependency we avoid needlessly
rebuilding this package every time git is updated.

Is there a particular reason to use a "Release" build here (as opposed
to the default "RelWithDebInfo")?  Guix is a hackers distro, and
debugging symbols are nice.  :-)

Just "Suite of tools to build EOSIO contracts".

Otherwise the patch looks great.  Can you send an updated version?

[Jesse Eisses]

Thanks for the feedback

As there are changes made to LLVM and libcxx for eosio-cdt I think we
have to compile them. These large dependencies are included as git
submodules though, so I will try to put them in separate packages.

The comments are clear; I'm working on an updated patch :)
