Thanks Steven,
i have done as you suggest but i had same result so i decided to clone a new csound repo and build all from zero.
But now trying build-wasm give me this:

ERROR:root:CsoundObj.bc: No such file or directory ("CsoundObj.bc" was expected to be an input file, based on the commandline arguments provided)

Thanks,
ciao,
francesco.

Hi Francesco,

I tried modifying the build-wasm.sh file to undo the changes Michael
did. I tested here by removing the CsoundObj.bc file and running the
updated build-wasm.sh again. I was able to get a complete build, and I
am using emscripten 1.37.13.

Could you try downloading the latest from develop branch and running
again? If it fails, could you email the build output to here or to me
offlist?

steven

ok, thanks Steven.
I'm no able to build csound wasm either with latest change but i found this:

It looks like the problem doesn't have to do with Csound but rather
that your Emscripten setup has problems. The log has:

The first line shows "+ echo Using EMSCRIPTEN_ROOT: $EMSCRIPTEN" where
it should have some kind of real path for $EMSCRIPTEN.

Did you source the emsdk_set_env.sh file that comes with emsdk?

The float version header is a real problem. We should either remove
this file or get the build to work both with, and without, it.

I don't see the problem except that it wasn't generated because the
Emscripten setup did not allow things to complete. Is there some other
problem?

Are you talking about the float version problem? This never worked for
me whether the Emscripten setup allowed things to complete or not.
This may be because I had done another build in the same CMake
context. But can we just remove this? What's the point besides causing
unnecessary problems?

I think you're discounting the likelihood that other people may have
different ways of building or different levels of experience. The
build should work out of the box as much as possible and for as many
of the several targets we support as possible.

Best,
Mike

I still don't understand by "float version" problem as you haven't
explained what the problem is, but just keep insisting there is a
problem. So I ask again, what is the problem that needs addressing?

BTW: Looking in my email archive, this was introduced 7 years ago.
Victor's rationale for it is here:

When Victor introduced this for the purpose of installing Csound for
plugin developers etc., the set of Csound targets was not so large as
it is now.

At that time, you commented:

Hi Victor,

Won't doing this mean one will not be able to compile both a float and
a double lib on the same system? I see how this will set a default for
an installation but I don't see exactly where it allows overriding.

Thanks!
steven

This is my point, or at least part of my point. We need to allow
overriding for developers who target different platforms. Of course
one can have multiple Csound repositories, one for each target, but I
would prefer that not be necessary.

In this case, the default MYFLT is double but for Emscripten it is float.

Best,
Mike

So again, I ask, for the last time, could you explain what problem you
are talking about? Please explain *exactly* what issue is occurring,
like "I can't compile something when doing a" or "this is breaking
here because of b".  I honestly don't understand what the problem is
you are referring to and, therefore, what is solved by removing
float-version.h.  Is it that you want to use the same physical headers
(from the same folder) even when compiling to multiple configurations
or something? (Which Victor addressed in that email thread by saying
use different folders?)

On my systems, I have been compiling with various configurations for
doubles with Emscripten, Windows (VS and MinGW), OSX, Android, iOS,
Linux. With the exception of iOS, I have done builds on all of those
platforms in the last few days.  Over the years, I've had separate
build folders for doubles and float builds and have had no problems.

So *please* frame what you are saying in concrete terms that I can
understand. I'm going to assume there's something you're doing or
wanting to do that is outside of the things I'm doing, but I need you
to explain the issue because I haven't seen any problems here.

I'm not sure what the concrete steps I took to get to my problem were,
but it happened when trying to build for Emscripten using the existing
scripts.

The existence of float-version.h implies, to me, that the Emscripten
build will fail if float-version.h does not exist or exists with MYFLT
defined as double.

Are you saying that different builds will re-create float-version.h
for the correct MYFLT type? I don't see what building in different
directories has to do with this.

Best,
Mike

Okay, that's helpful. Yes, float-version.h is compiled into the
current build folder (it's in include/CMakeLists.txt, line 5). If
CMake doesn't run, that float-version.h won't get created from the
float-version.h.in file. The generated float-version.h in the build
folder gets used by CMake as a source file (same as generated c files
from flex/bison).  The install script also copies the float-version.h
into the target include directory, but that only comes up for
distribution, not build-time.

So the problem with Francesco's build *should* be the misconfigured
Emscripten. That looks to cause Cmake not to run to completion (which
was reported in the log) and then the failure to compile because no
float-version.h exists.

If you have a problem building with Emscripten, I would guess it was
something like the above rather than a problem with float-version.h.
(This is a guess as I've compiled with Emscripten on OSX and multiple
Linuxes without problems with float-version.h)

Okay, I didn't get that float-version.h gets picked up by make from
the build folder.

I did not look there for my failed Emscripten build (which currently
is succeeding) for float-version.h because I did not know that.

Best,
Mike

ok sorry for that i did not look properly!
Anyway i have succefull build csound wasm but again i have initial 
problem, i.e.:

Welcome to Wasm Csound !
0dBFS level = 32768.0
--Csound version 6.10 (float samples) Nov 18 2017
[commit: aa4662ef93506e6b9e5d54e6f9e4d4c26dbe004a]
libsndfile-1.0.25
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?)

i have also modified this last line in build-wasm.sh:

cp build-wasm/libcsound.js.map dist-wasm/

in

cp build-wasm/libcsound.wasm.map dist-wasm/

because i see only this last file.

If interested attached is buil-wasm output log

Thanks,
ciao,
francesco.

I think I found the issue and fixed it. I was able to reproduce the
error just by testing the built wasm file using the examples.  The
cause looks to be that in commit fba4b25, Michael added ASSERTIONS=1.
This caused the assertion error but also revealed that those functions
were optimized out. Likely those functions rarely get used so it was
not an issue until the assertions were on.  I added marking up of
functions to use EMSCRIPTEN_KEEPALIVE and that seems to have done the
trick.  Tested in Firefox, I could run Trapped in the browser just
fine here. (I also added your fix for the .map file copying)

Give the latest from develop a try and let us know if you have further
problems.  (And thanks for reporting the issue!)

Hi Steven,
yes it is working now. Many many thanks.
I will try some more in the next days.
Just another stupid thing: it is missing the message (welcome message?)

Not so important :)

Thanks,
ciao,
francesco.
