Libcpp compilation integration by 123R3N321 · Pull Request #976 · Lind-Project/lind-wasm

123R3N321 · 2026-03-23T18:48:00Z

Integrate libcpp compilation into main codebase

libcpp compilation toolchain cmake file and compile .sh script used to generate artifacts, stored in artifacts/ directory. Note the toolchain cmake and bash scripts are removed after one-time use to create the artifacts. (According to Alice, they are still tracked in lind-wasm-apps repo?)
Additional makkefile script to compile cpp into wasm/ Note we are suppressing throw-exception syntax. This will be a major fix in the future. See scripts/lind_compile_cpp
documentation in .md, found in docs/ dir.
CI integration with additioanl html rendering in e2e report: added libcpp test report with one singular unit test using the algorithms.h header.

Document changes made by Alice and Ren in an attempt to compile .wasm from cpp source file

Create simple cpp program using <algorithms> header to test libcpp headers

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>

Add error msg of cpp compilation attempt, which is being fixed right now

Add ignore for llvm external dependencies

Add .cmake to be used for build script to build llvm for .wasm bin result

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

Modify llvm-project source code needed for compilation. Not tracked in git but documented and Ren will submit another PR for the documentation

Add cosmetic for .md rendering

Yaxuan-w

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:

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

What does everyone think about that?
