Compilation into WebAssembly fails
zavalyshyn opened this issue · comments
Hi,
First of all, thanks for making this project available to everyone. That's a fantastic job.
I'm trying to compile pocketsphinx.js into a WebAssembly as explained here and the build goes fine up until it fails when trying to find a file or a folder. The problem I can't find where exactly it fails. Maybe you can help?

A file build.make located at pocketsphinx.js/build/CMakeFiles/pocketsphinx.js.dir contained a weird \ symbol in the end of line 57. And if I'm not mistaken it should not be there since there are no other commands for that make target afterwards.
CMakeFiles/pocketsphinx.js: libpocketsphinx.so

pocketsphinx.js: CMakeFiles/pocketsphinx.js.dir/build.make
Deleting that \ symbol and re-running make results in a successful build of pocketsphinx.wasm and pocketshpinx.js files.
Hope it helps
