wasm-ld: error: 'atomics' feature is disallowed #1087

Open nsourligas opened 2 years ago

nsourligas commented 2 years ago

Hi,

I am trying to compile my Qt5 application (using protobuf) into wasm following Qt instructions. But the compilation fails at the last generated file which is the application js file. Any idea why this is happening?

I looks like you didn't compile your main.c or main.cpp file with -pthread (or -sUSE_PTHREADS).

sbc100 commented 2 years ago

With pthread programs all source files (technically all source files that use atomics and/or TLS) need to be compiled with this flag.

Even though it seems that I am compiling all the source files with the option -s USE_PTHREADS or -pthread now the same compilation errors as shown below appeared (setting WASM_MEM_MAX didn't change anything):
