@jeffd said in error C2148: total size of array must not e xceed 0x7fffffff bytes.:

on mac it works fine

Same version of Faust?

[jeffd]

@d-healey yes and no actually. I first tried it with the older version of faust im using on mac. 2.63 I believe?

got the c2148 error

then i updated faust and hise to the latest to see if that would fix it.

same issue.

[d.healey]

@jeffd You built HISE from source?

[jeffd]

@d-healey using that script

REM Build HISE
%projucer_path% --resave "%output_dir%/HISE\projects\standalone\HISE Standalone.jucer"
%msbuild% "%hise_source%\projects\standalone\Builds\VisualStudio2022\HISE Standalone.sln" /p:Configuration="Release with Faust" /verbosity:minimal

[d.healey]

@jeffd Does it work if you use a scriptnode network without faust?

[jeffd]

@d-healey let me try it and see

[jeffd]

@d-healey yes it worked

i was able to compile a dll with just a simple scriptnode effect

so it is something to do with faust

Or that particular faust effect. Try the most basic faust effect you can think of and see it that works.

[jeffd]

@d-healey ok

let me try something.
this one i was doing before was just a smooth delay.

i think there is an even simpler one

[jeffd]

@d-healey yeah it must be that particular effect.

a tried an even simpler delay and it compiled and worked!

seems so odd. works on mac but not on windows.

it was just the smooth delay i am using found here:

delayEcho - Faust Documentation

(faustdoc.grame.fr)

that is throwing the error.

doesnt seem that complicated but that is the problem.

Ill try to smooth out the other delay that works with some smoothing nodes in scriptnode to try to match my mac version i guess.

@jeffd the problem is if you use a Faust effect with lots of delay lines in a polyphonic context it blows up the memory size of the C++ class that the faust code generator is trying to build.

I „fixed“ that a few months ago by defaulting to a non-polyphonic FX code generation so make sure you use the latest build and that the polyphony flag of the network is unticked.

@Christoph-Hart
ok thanks!

i got it working with a different delay type.

but ill try this fix as well.
