static binary with builtin lld and libclang

[prologic]

Can we compile tre as a statically linked binary without os.Exec'ing to clang and ld?

[Nv7-GitHub]

That would be super cool! However, how would it be done?

[prologic]

Are there no llvm Go libraires that can do this?

[Nv7-GitHub]

There seem to be a few, so I'm going to try to compile them, so far it isn't working, so I've opened some Issues

[Nv7-GitHub]

This seems to be the only actively maintained one, so I made an issue here: tinygo-org/go-llvm#22

Some other ones I found are:

• https://github.com/go-llvm/llvm
• https://github.com/nsf/gollvm
• https://github.com/axw/gollvm

Nice!

I was able to get it to work with https://github.com/Nv7-GitHub/go-llvm and brew install llvm@9

The binary size is 57MB....

That's really nice! I love it! Is it also statically linked?

[Nv7-GitHub]

Kind of...
Here is what it is linked to:

        /usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.11)
        /usr/lib/libncurses.5.4.dylib (compatibility version 5.4.0, current version 5.4.0)
        /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.100.5)
        /usr/lib/libxml2.2.dylib (compatibility version 10.0.0, current version 10.9.0)
        /usr/local/opt/libffi/lib/libffi.7.dylib (compatibility version 9.0.0, current version 9.0.0)
        /usr/local/opt/llvm@9/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1.0.0)

So it isn't linked to libLLVM, but it requires LLVM's libc++ and libffi

I see

I don't think it can build static binaries though, just create LLVM IR/bitcode and JIT compile and run it
