npm install error in unknown connect.c file

[ghost]

Hi,

After installing node v12, I ran npm install in the odas directory. I'm getting an error in connect.c file in directory /home/pi/odas_web-0.3/node_modules/grpc/build/Release/obj.target/boringssl/deps/grpc/third_party/boringssl/crypto/bio/.

I am not sure why this error is popping up in first place because the bio folder shows only bio.o and bio_mem.o files, and neither connect.o nor connect.c file.
Please have a look at the error and let me know if there's any issue or if I'm missing something.

Best

Hi, the issue is that grpc, a package on which ODAS Studio depends, needs to be build from source on arm cpu, but the build fail.

I suggest you first try to export CXXFLAGS=-Wno-error before running npm install to stop treating the warning you get as an error.
You can also try bumping the grpc version in package.json to 1.25.0.
You may also have more success using Node.js 10 instead of 12, even if 12 is the current LTS.

I find this issue, this issue and this issue to be of interest.
I don't have an arm machine available for testing so I don't know if it'll work.
I searched with "node-gyp grpc build fail" and "grpc cast between incompatible function type" to find info.

Upgrading grpc to 1.24.2 in package.json worked for me. I hate NPM. The worst package manager on earth. I don't understand how javascript/node is the most widely used software language in the world. It's terrifying.
