GDB зависает, пытаясь открыть файл / proc на bash на Windows на Ubuntu 16.04.2 LTS [закрыт]
Я установил Ubuntu 16.04.2 LTS на свою Windows 10 и получил проблему, когда GDB зависает, пытаясь вызвать popen:
$ sudo gdb out

(gdb) r

warning: unable to open /proc file '/proc/2710/status'
warning: unable to open /proc file '/proc/2710/status'
Program terminated with signal SIGKILL, Killed.
The program no longer exists.
Все нормально, когда вы вызываете из оболочки.
main.cpp код:
#include <iostream>
#include <string>
using namespace std;
int main(int, char*[])
{
char buffer[1024];
FILE* f = popen("ls -la", "r");
if (f != nullptr)
{
while (!feof(f))
{
if (fgets(buffer, 1024, f) != nullptr)
{
cout << buffer;
}
}
pclose(f);
}
return 0;
}
команда компиляции с информацией об отладке:
g++ -g main.cpp -o out
и без:
g++ main.cpp -o out
