Integrate libcpp compilation into main codebase

  1. libcpp compilation toolchain cmake file and compile .sh script

2.documentation in .md

  1. TODO: CI integration

@123R3N321
Add libcpp header modifications doc file in .md
b79fe5b 
Document changes made by Alice and Ren in an attempt to compile .wasm
from cpp source file
@123R3N321
Create test file for cpp compilation
10d26e7 
Create simple cpp program using <algorithms> header to test libcpp
headers
@123R3N321
Modify lind_compile script for cpp compilation
68c5f23 
Change compilation command from clang to clang++, now the compile script
compiles cpp instead of c. Future changes needed to accomodate both

Also note due to mysterious reasons absolute path is needed when
callling this compile script: scripts/lind_compile <other args>
@123R3N321
Update cpp_compile.md
7501bac 
Add error msg of cpp compilation attempt, which is being fixed right now
@123R3N321
Update .gitignore
e583137 
Add ignore for llvm external dependencies

Add .cmake for wasi compilation
b3ab4d6 
Add .cmake to be used for build script to build llvm for .wasm bin
result
@123R3N321
Add build-llvm.sh
412310a 
Add build script for llvm for .wasm compilation result. Note the
compiled wasm32 .a archive file must be manually migrated to the sysroot
under /build
@123R3N321
Add build script for llvm archives

We need to discuss how we want to standardize cpp testing.

  • I'm thinking to have a separate folder under tests/ called tests/cpp/ for all cpp unit test
  • cpp compilation scripts can be put under scripts/cpp and put lind_compile into scripts/c, rust version into scripts/rust (or sth similar)

I think we need to move most of this to the lind-wasm-apps repo.

We should add the integrations to compile cpp into the lind_compile script however. It should just check that libcpp is properly installed and fail gracefully with "libcpp not installed" error if not.

@m-hemmings regarding the CI problem:

Nick has brought to my attention that the current workaround for libcpp header involves this workflow: git clone llvm-18 ->modification of llvm source code -> compile archive files -> copy over to /build/sysroot -> sysroot provides dependency for clang++ to compile cpp source code.

This is problematic. On the one hand, llvm is big and preserving their source code in our repo is confusing; on the other hand, as Alice points out:

Source code and scripts in separate repos will make things hard to understand. We can use prebuilt libcpp.a for ci

However, this implies that, should there be any upgrade of llvm to version beyond 18, we will need to re-create this entire workflow to compile an updated version of the .a archive(s) needed for libcpp header support. I will do my best to document this workflow and, for future improvements, automate the process as far as I can

Nick also points out that we are using llvm-16 in lind-wasm-apps repo, see commit 0e78686; while my PR for lind-wasm repo is now using llvm-18, this is consistent with the docker config in this repo.

Thanks for writing this up. I agree that the current approach puts us in an awkward spot: keeping LLVM source in the repo is heavy and confusing, but moving all of the logic somewhere else also makes the workflow harder to understand and maintain.

I think there is a cleaner middle ground. Instead of treating libc++ support as something we rebuild from LLVM source during normal CI, we could treat it as a versioned toolchain artifact.

Concretely, I would suggest:

  • Keep one documented build script in this repo that knows how to produce the exact libc++ headers and archive files we need for a given LLVM version.
  • Run that script only when we intentionally upgrade LLVM or change the libc++ workflow.
  • Publish the result as a named artifact, for example an LLVM-versioned sysroot overlay or tarball.
  • Have CI download and unpack that artifact instead of cloning and rebuilding LLVM as part of ordinary PR validation.
  • Add one small smoke test in CI that compiles a trivial .cc file with clang++ so we catch regressions immediately.

That gives us a few benefits:

  • The normal CI path stays much smaller and easier to reason about.
  • We keep the process reproducible because the generation script still lives here.
  • We avoid preserving a large LLVM source tree in the repo.
  • Future LLVM upgrades become an intentional refresh of a pinned artifact.

On the versioning point, I do think it would help to align on a single LLVM major version across repos if we can. This repo is already pinned to LLVM 18 in Docker, so moving lind-wasm-apps to the same version would make the overall story much easier to follow.

So in short, my suggestion would be:

  1. Keep the build recipe in-repo.
  2. Stop keeping LLVM source in-repo for day to day CI.
  3. Publish a prebuilt, versioned libc++ support artifact for CI consumption.
  4. Add a simple C++ compile smoke test so the setup stays honest.

What does everyone think about that?

Removed separate libcpp integration testing job in CI as instructed by @Yaxuan-w

Added scripts/harnesses/libcpptestreport.py following the styling of wasmtestreport.py in the same directory as instructed by @rennergade Currently passing 1/1 test.

this test just verifies compilation? It would be cool to actually run the programs like the main tester does

The lind_compile_cpp script actually has a ton of space for improvement since it is literally scrambled up from scraps taken from the original lind_compile script.

will we have the need to preserve such a flag in the future? I have it here simply because, well, I haven't deleted it after copy-pasting the original lind_compile script.

There is much to do, as almost everything in this script assumes c source code usage (such as the prompt when you pass in -help flag). I will see to it after getting all the more important parts done

We can remove grates related part at least. But yeah this has less priority than others

Done.

ok I'm not sure I want this to show up on the official documentation site yet... I will look into it and possibly rework the entire documentation one this PR is truely ready for merge, so that future devs know what is going on.

Removed separate libcpp integration testing job in CI as instructed by @Yaxuan-w
Added scripts/harnesses/libcpptestreport.py following the styling of wasmtestreport.py in the same directory as instructed by @rennergade Currently passing 1/1 test.

this test just verifies compilation? It would be cool to actually run the programs like the main tester does

Done. a couple assumptions:

  1. lind_run is used as blackbox to execute .wasm
  2. I "suppressed" the comipler warning regarding main func argument list style so that the report looks less noisy.
