Makefile/emscripten woes (em++: error: wasm: No such file or directory)

s1gtrap commented 3 years ago

I'm trying to get this compiling on macOS Big Sur (11.2.3 (20D91)), but keep getting errors and I'm kind of at a loss at this point.

I tried following src/emscripten/README.md, cloned the latest emsdk (ac98ca), and already the confusion set in, as <path-to-emsdk-repo>/emsdk.sh is not a thing. Okay, I figured you meant <path-to-emsdk-repo>/emsdk_env.sh, so I tried that.

Next up was some syntax error, figured it was some Python stuff so upgraded from 2.7.16 to 3.9.2 and got that playing nice.

Then, in trying to run make -C src emscripten_build ARCH=wasm wasm_simd_post_mvp=yes, I get

em++: error: wasm: No such file or directory ("wasm" was expected to be an input file, based on the commandline arguments provided)

for which I'm at a complete loss. I've run make net etc. and I'm not even sure why it would look for a file named wasm. I also tried with a newer GNU make (4.3 instead of 3.81), no dice.

I also tried make -C src build ARCH=wasm32-unknown-unknown (from niklasf/stockfish.wasm iirc) for which I got the mysterious albeit kinda interesting

make: *** [Makefile:831: config-sanity] Error 1

until I realised that Makefile:831 simply validates ARCH, so yea.. no dice either.

First of all, thanks for trying it out! I haven't tested on other environment than my machine (archlinux), so I appreciate reporting build error like this. So, let me see...

<path-to-emsdk-repo>/emsdk.sh is not a thing.

Oh, good catch, you're right, I meant <path-to-emsdk-repo>/emsdk_env.sh there. I'll update README.md.

I get em++: error: wasm: No such file or directory ...

Off the top of my head, I have no clue. Could you attach the whole log of make -C src emscripten_build ARCH=wasm wasm_simd_post_mvp=yes?

I also tried make -C src build ARCH=wasm32-unknown-unknown ...

That is not supposed to work on my port.

A few things I want to ask:

What happens if you just run make -C src build (or actually same as make -C src build ARCH=x86-64-modern)? it should build normal Stockfish executable same as official repo.
Have you tried building official stockfish (https://github.com/official-stockfish/Stockfish) on your machine? If that fails, then maybe you can find answer on the official repo.

Edit:

one more question

Have you tried building other emscripten project (or some toy example)?

By the way, the versions of tools on machine are like this:

Huh, neat! I happen to be dual booting Arch, so that's good to know!

Sure thing.

Figured as much 😉

I actually thought that worked fine, but apparently not, as

Yep. Fresh checkout on master, producing a perfectly runnable stockfish

Have you tried building other emscripten project (or some toy example)?

I wouldn't know where to find these but I'll have a look around.

hi-ogawa commented 3 years ago

Thanks for reporting back the detail. I think I identified where the issue is:

https://github.com/hi-ogawa/Stockfish/blob/a0ad14f1ca34e24ef459482b1da90c85472f664e/src/Makefile#L390-L394

When host kernel is automatically picked up as Darwin, there are some special compiler options added (in this case -arch wasm), which emscripten doesn't understand. So manually setting KERNEL=Linux could be a workaround (possible with OS=GNU/Linux).

Btw, you can check successful build log from Github Actions CI as in https://github.com/hi-ogawa/Stockfish/runs/2183230332?check_suite_focus=true#step:5:1.

Actually, this doesn't explaine why simple make -C src build fails. I have no idea about it, so it would be great if you can debug yourself by removing/adding some lines from Makefile. FYI, there are only a few lines different from upstream https://github.com/official-stockfish/Stockfish/compare/master...hi-ogawa:emscripten#diff-3e2513390df543315686d7c85bd901ca9256268970032298815d2f893a9f0685.
