Troubleshooting target program crash

[martty]

Hey, thanks for this great library! I am having trouble making it work though. Here is what I tried:

• get the blink repo
• build blink x64 Debug (Microsoft (R) C/C++ Optimizing Compiler Version 19.16.27012.6 for x64)
• create target directory & cd there
• create test.cpp with:

  
  #include <iostream>
  void fn();
  int main() {
  while (true) {
      fn();
  }
  }

using std::cout; using std::endl; void fn() { cout << "Hello World" << endl; }

 - compile test.cpp in a VS console with `cl.exe /Z7 /Od /MDd /nologo /EHsc /std:c++latest test.cpp`
 - cd back to blink root
 - launch blink with test.exe (`bin\x64\Debug\blink.exe target\test.exe`) in VS console
output:

  - change output string in test.cpp to something else & save

The target application has exited with code 3221225501.
  - the test.exe program crashes

  - the additional change in blink was that I disabled commandline detection from the .obj file, as that didn't work, so the commandline used to build is the built-in (as described in #13)

Use /ZI instead of /Z7 for command-line detection. I'll look into the crash, seems to be some CRT state getting corrupted.

[Trass3r]

Is /ZI required or could the implied /FC be enough?

[crosire]

/FC has no impact on the debug data stored in the object files (it only affects display in the command-line output), and that's what blink needs to determine the compiler command-line. So for that to work /ZI is required.
