@jprendes I think you're wayyyyyyy more well versed in C++ world than I am. Any ideas? (you can ignore this if you don't want to get involved with my debugging; that's OK too) If I were to guess, I'd say that my GitHub Codespaces (the env where I'm working) is using some kind of outdated apt repo or Ubuntu install? @jcbhmr ➜ /workspaces/llvm-box (main) $ cat /etc/os-release

I'll try reverting to the "known good commit" referenced in the original # This is the last tested commit of llvm-project.
# Feel free to try with a newer version
git reset --hard d5a963ab8b40fcf7a99acd834e5f10a1a30cc2e5See if that works? I made a new branch origin/last-tested or https://github.com/jcbhmr/llvm-box/tree/d5a963ab8b40fcf7a99acd834e5f10a1a30cc2e5 It's from Oct 27, 2022 so not that old Testing now... |

Same error 😡
|
|
Maybe I need to run it in the Docker container just like "build-with-docker.sh" does in the original? docker run \
-it --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
-v $(pwd):$(pwd) \
-v $(pwd)/build/emsdk_cache:/emsdk/upstream/emscripten/cache \
-u $(id -u):$(id -g) \
$(id -G | tr ' ' '\n' | xargs -I{} echo --group-add {}) \
emception_build:latest \
bash -c "cd $(pwd) && ./build.sh" |

Still fails... 😡 But for a different reason... 🤔 @jcbhmr ➜ /workspaces/llvm-box (last-tested) $ ./build-with-docker.sh

The libtinfo.so seems to be something ncurses related? https://stackoverflow.com/questions/48674104/clang-error-while-loading-shared-libraries-libtinfo-so-5-cannot-open-shared-o |

Or maybe there's an easier solution? https://stackoverflow.com/questions/70236887/when-installing-wldc-libtinfo-so-5-cannot-open-shared-object-file |

What emscripten version are you running in your original environ? As for the new error, it sounds like you are trying to use the tblgen built in the original environment inside the container. You should build tblgen inside the container as well to ensure all the host library dependencies are correct. As a first step, check the emscripten version. It looks like you might be using the version in the ubuntu repositories. Try installing a recent version following the instructions in the emscripten website. |

/re @jprendes
In my Codespaces devcontainer, this feature https://github.com/ebaskoro/devcontainer-features/tree/main/src/emscripten installed emscripten v3.1.32 which is newer than the one used in the Docker container which was emscripten/emsdk:3.1.24 emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.32 (eab98adf462c39f3c31d348331c4830bcaa36949)

I'll do that and report back (sorry if I keep pinging you with updates; I noticed you "watch"-ed this repo 😜 you can un-watch if you don't want to listen to my mini-blog issue log)
Sounds good! I think I am on a pretty latest version https://github.com/emscripten-core/emscripten/blob/main/ChangeLog.md but it is different in the Dockerfile that I'm trying from the https://github.com/jprendes/emception/blob/366065547b1a59cb58011ed19aedce70c3bcbd2b/docker/Dockerfile # This is the last tested version of emscripten.

Could be that something changes in either llvm or emscripten that causes the error. I can try look into it tomorrow. |
|
/re @jprendes
Thanks! Don't feel obligated to do so if its too much work. I'm sure I'll figure it out. I can always ask on StackOverflow or Reddit or something. |

I got farther! I did Run Build Command(s):/usr/bin/ninja cmTC_8f8ee && [1/2] Building CXX object CMakeFiles/cmTC_8f8ee.dir/src.cxx.o

I think I solved it! Maybe. I found the root cause though by
Note that $SRC in there? That var I deleted. It's now pointing to /emlib/fsroot.js instead of ./emlib/fsroot.js 🤦♂️ |
|
So yeah I need to add this file: https://github.com/jprendes/emception/blob/366065547b1a59cb58011ed19aedce70c3bcbd2b/emlib/fsroot.js and in theory that MAY solve it? |
|
To standardize the version of LLVM that we work with, I think we should use the latest version tag from LLVM and try to stay in sync with it... Key is try. Currently, that's 8dfdcc7 from llvm@8dfdcc7 https://github.com/llvm/llvm-project/releases/tag/llvmorg-15.0.7 |
|
btw this was the key to me figuring out that the cmakeerror.log existed:
|
|
Getting farther! Fixing that fsroot.js issue went a long way! In the docker container, I got past the libstdc++ v7 check or whatever, so now I'm waiting 20min+ to see if it builds
|
|
🎉 Something happened!
|
|
Now we'll see if I can replicate that success in the main branch... |
|
main is now at https://github.com/llvm/llvm-project/tree/release/15.x and then we can extend from there at the time, that's https://github.com/llvm/llvm-project/tree/llvmorg-15.0.7 v15.0.7that's the current testing target for LLVM stuff |
Draft

Success on building it with v15.0.7!
@jprendes you don't need to debug it anymore, just go to https://github.com/jcbhmr/llvm-box/tree/2f4745b31ed17a08815f570c1fb32737cfbeac4d and click Code -> Codespaces -> new codespace on get-it-working. Hopefully it works for you too! 🎉
As you can tell I'm very happy 😊 that I got it working. BUT there's still more to do. That's only up to the cmake part of the second build part. There's the actual invoking of the cmake generated Ninja script that still needs to pass... # Make sure we build js modules (.mjs).
# The patch-ninja.sh script assumes that.
sed -i -E 's/\.js/.mjs/g' $LLVM_BUILD/build.ninja
# The mjs patching is over zealous, and patches some source JS files rather than just output files.
# Undo that.
sed -i -E 's/(pre|post|proxyfs|fsroot)\.mjs/\1.js/g' $LLVM_BUILD/build.ninja
# Patch the build script to add the "llvm-box" target.
# This new target bundles many executables in one, reducing the total size.

Thanks @conartist6 for the idea of posting literally everything to issue logs. 🙏 I just reread all this today and thank goodness I wrote it all down or I'd have forgotten what I did and how I solved it. Thanks for your inspiration! TODO: solve the ninja patch script thing. |

That means having an actual .wasm file. This could be a while!
