Mac OS 10.4.6 npm installation error: unknown type name 'constexpr'

[tom-longmeadow]

Hello. I have installed pocketsphinx and have successfully run the hello_ps.c example. I am now trying to get the npm version installed. When installing I get an error: unknown type name 'constexpr'. I have looked up reasons for this error and they suggest compiling with c11, but i am unsure how to set this up for the npm installation.

relevant part of the build:

[nshmyrev]

add -std=c++11 in cflags in cmakefile

[simon-tannai]

@nshmyrev I have the same issue than @tom-longmeadow but I'm not familiar with C and make file.
Can you details how to fix it and whare add the -std=c++11 ?

[nshmyrev]

@nshmyrev I have the same issue than @tom-longmeadow but I'm not familiar with C and make file.

What is your OS, compiler, compiler version, cmake version, full build output right now.

[simon-tannai]

@nshmyrev I'm using MacOS Catalina 10.15.7 with Node.js 12.18, cmake-js 6.1.0, cmake 3.19.2.
The issue happened when I ran npm i --save pocketsphinx.

Swig doesn't support very recent node I think, maybe 0.10 will work.

[simon-tannai]

@nshmyrev I tried with Node.js 0.10.48 but cmake-js seems to not support this old version.
According to the documentation, I tried with cmake-js@5.3.2 but I got an error from the package:

for (var key of _.keys(npmConfigData)) {

Maybe you have more information about version to use ?

[nshmyrev]

Given the software is from 2016, something like 3.2.0 or 3.4.0 should probably work.

[simon-tannai]

@nshmyrev I tested both version, I got same errors :(

[nshmyrev]

Are those files (node.js, module.js) too recent? Maybe they come from very recent npm or something.

[nshmyrev]

You can try instead https://github.com/alphacep/vosk-api/tree/master/nodejs, I tested it recently and it should work with node 0.10

[nshmyrev]

You have to compiler kaldi properly first though, also not a trivial thing.
