I am attempting to compile two files in two child process I create from Node.js' child_process module with .spawn() in parallel, basically looping over sources and spawning two shells immediately.
However only one file will be compiled and it's not always the same. One child_process will retu with error code 2.
Is cl.exe to be known to not being able to run two instances? I am assuming that running it sequentially will fix this problem.
Note: setting or unsetting /MP flag doesn't change this behaviour.
