Raspberry Pi 1B - nmqtt - exit code 137

[mantielero]

Just for the record, I am trying: 
    
    
    nim --cpu:arm --cc:clang --clang.exe="zig cc" --zig.options.linker: 
"-target arm-linux-musleabihf" --zig.options.always: "-target 
arm-linux-musleabihf" c alarma.nim
    
    
    Run

but it looks I am hitting the same problem: 
    
    
    CC: stdlib_assertions.nim
    CC: stdlib_dollars.nim
    CC: stdlib_formatfloat.nim

but I saw Araq saying it wasn't Nim fault.

Any work around?
