system_error: thread constructor failed

[Dari0GR]

good day friend

When I want to use ./record output.kbd it shows me the following:

❯ ./record output.kbd Usage: ./record output.kbd [-cN] -cN - select capture device N -CN - number N of capture channels N

Recording 11 frames per key press Found 1 capture devices: - Capture device #0: 'Built-in Microphone' Attempt to open capture device 0 : 'Built-in Microphone' ... Opened capture device succesfully! DeviceId: 2 Frequency: 16000 Format: 33056 (4 bytes) Channels: 2 Samples: 512 Audio Filter: 1 Cutoff frequency: 100 Hz Capturing audio .. libc++abi: terminating with uncaught exception of type std::__1::system_error: thread constructor failed [1] 2348 abort ./record output.kbd

What operating system and compiler are you using? It appears your environment does not allow thread creation.

What happens if you try to build and run the following test.cpp program:

#include <thread>
#include <cstdio>

int main() {
    std::thread test([](){});
    test.join();
    printf("OK\n");
    return 0;
}

g++ test.cpp -lpthread
./a.out

Todo este fue el proceso que hice de principio a fin:
