enable, fix(main/odin): copy build instructions from odin repository

[0dminnimda]

I have been able to successfully build odin using proot-distro and it ran just fine. So it seems like the issue has been fixed from the odin side. One possible problem is that odin requires libllvm versions (11-14, 17, 18), but current versoin is 19, will see if it'll cause problems.

(If it were still open)
Closes #10892

How would one check that this have successfully build, before merging?

[twaik]

Commit description must have specific structure.

[0dminnimda]

I suppose it's fine to squash commits on merge

[0dminnimda]

Or should i rebase? And change all descriptions

[0dminnimda]

Can error like

llvm-config: error: missing: /home/builder/.termux-build/_cache/android-r27b-api-24-v1/lib/libLLVMMCA.a
llvm-config: error: missing: /home/builder/.termux-build/_cache/android-r27b-api-24-v1/lib/libLLVMX86TargetMCA.a

be fixed using something like?

_LLVM_MAJOR_VERSION=$(. $TERMUX_SCRIPTDIR/packages/libllvm/build.sh; echo $LLVM_MAJOR_VERSION)
_LLVM_MAJOR_VERSION_NEXT=$((_LLVM_MAJOR_VERSION + 1))
TERMUX_PKG_DEPENDS="libllvm (<< ${_LLVM_MAJOR_VERSION_NEXT}), ..."

Unfortunately we do not provide lower versions of llvm in main repo, so in the case if you do not find a workaround for build errors the PR will be closed.

[0dminnimda]

Yeah, so those errors are basically the same as those I got when trying to compile locally.

Does this mean that all currently build packages use the llvm 19?

[twaik]

Correct.

[0dminnimda]

My line of thinking was: I don't want to build llvm just for this, but a build server can do it. So if odin depends only on the libraries and not the headers, should we entertain such idea?
Of course I'll see if it could be fixed by a simple patch, but still.

[twaik]

The github of the odin-lang project is active. You can simply open issue about llvm-19 support.

[0dminnimda]

The changes seem to be pretty pasic. I'll merge a pr there and come back to pull it up here
