Using custom libs .a files

[Mehaboob kk]

Hello All,

I see that Emscripton allows to compile .a files to wasm. In order for this to work the .a file need to be originally compiled using gcc? if yes, any specific version to be compatible? 

Thanks,

Mehaboob

Hi Mehaboob,

No, Emscripten cannot compile native objects or archive files to WebAssembly. Perhaps what you saw was a reference to archive files containing WebAssembly objects produced by Emscripten?

Hi Thomas,

Thanks for your input, I was referring to the Using Libraries section here https://emscripten.org/docs/compiling/Building-Projects.html#using-libraries

 As Thomas says, you can't use native object files with emscripten, so you don't need gcc at all.  All the instructions one that page refer to building libraries with the emcc compiler.   When you use emcmake and emconfigure it configures your project to use emcc rather than any host/local compiler.

cheers,
