undefined symbol: PATH_FS after updating to latest incoming

[Александр Гурьянов]

Hi guys! Just updated to latest incoming
(39158e5e344460d5c0a5da8913f87e4cb0db6e4a) and now have this error
that does not exists on previous version:

error: undefined symbol: PATH_FS
warning: To disable errors for undefined symbols use `-s
ERROR_ON_UNDEFINED_SYMBOLS=0`

Have no idea what is PATH_FS, and why it's not defined. I tried -s
FORCE_FILESYSTEM=1 but has no effect.

Thanks.

[Floh]

I just checked with my code, and everything still works, *but* I'm using NO_FILESYSTEM everywhere (there was a similar problem a few weeks ago too though: https://github.com/emscripten-core/emscripten/pull/8464)

[Александр Гурьянов]

Hmm, will try to bisect, my code definitely uses filesystem.

I recently split up PATH into PATH and PATH_FS, where PATH_FS is the part that depends on FS being present. Sounds like that might have caused a bug somehow. If you build with -s VERBOSE=1 it should print the decisions it makes when adding symbols, and then it should say which ends up requiring PATH_FS. Then hopefully we can figure it out from there. (Or, if you can provide a testcase I can look at that directly.)

This is VERBOSE=1 output:
lone.js && cd /home/caiiiycuk/emscripten/cats/project/emscripten &&
gpx tools postbuild wasm wbin-standalone.js
VERBOSE is on, this generates a lot of output and can slow down compilation

Thanks! Yeah, this was a typo in Mix_LoadWav_RW's deps. Fix in

https://github.com/emscripten-core/emscripten/pull/8587

Please let me know if that doesn't fix things for you.
