Hi All,
trying wasm csound i have this printed in console:

Csound Started !
Assertion failed: Cannot call unknown function FileList_getFileCount (perhaps LLVM optimizations or closure removed it?)
Assertion failed: Cannot call unknown function FileList_getFileCount (perhaps LLVM optimizations or closure removed it?)

so there are no files listed on the page.
Is it something wrong with my wasm build?

I'm on Ubuntu 16.04 Csound latest develop, emsdk 1.37.13 also tested with emsdk 1.37.22

Thanks,
ciao,
francesco

Hi Francesco,

I see this change in build-wasm.sh:

-emcc -s LINKABLE=1 ../src/CsoundObj.c -I../../include -Iinclude -o CsoundObj.bc
-emcc -s LINKABLE=1 ../src/FileList.c -Iinclude -o FileList.bc
+emcc -O2 -g4 ../src/FileList.c -s LINKABLE=1  -s ASSERTIONS=1
-Iinclude -o FileList.bc
+emcc -O2 -g4 ../src/CsoundObj.c -s LINKABLE=1 -s ASSERTIONS=1
-I../../include -Iinclude -o CsoundObj.bc

That adds -O2 -g4 to the build settings for FileList.c and
CsoundObj.c.  I suspect this is causing an issue.

1. Could you try locally to take out -O2 -g4 from those two lines in
build-wasm.sh then building?
2. Michael Gogins: This was introduced in your commits; I don't know
if this was intentional?
