Mingw64 from msys2 creates corrupt executable #287

I am currently using MSYS_NT-10.0-22621 Legion 3.4.7.x86_64 2023-07-14 16:57 UTC x86_64 Msys
and using mingw64

My mingw64 version is

g++.exe (Rev7, Built by MSYS2 project) 13.1.0
Copyright (C) 2023 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

I wrote a simple main.cpp file which contained.

#include <iostream>


int main()
{
	std::cout<<"Hello world"<<std::endl;
}

However, while building it, even though it creates a .exe file, it doesn't output anything.

So, I install a previous version, using Mingw Natively.
And my version was

g++.exe (MinGW-W64 x86_64-ucrt-posix-seh, built by Brecht Sanders) 12.3.0
Copyright (C) 2022 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

For Comparison, I compiled the same file into assembly.

My command was same for the both version, (without any optimisation option)

g++ .\main.cpp -S

for executable

g++ .\main.cpp -o .\main.exe

Using pacman -Qq | grep gcc in msys2shell, mingw64shell and ucrt64shell,
I get these packages

gcc-libs
mingw-w64-x86_64-gcc
mingw-w64-x86_64-gcc-ada

mingw-w64-x86_64-libgccjit

Same for all the shells

When I ran $ pacman -Qi gcc-libs in the shell it returned:

Running executable generated from 13.1 outputs nothing where, 12.3 executable outputs correctly. It used to work before I updated it. I also used same version of Mingw natively, and it had the same problem.

I also posted this on StackOverflow for help. Here is the link

Is it some sort of bug in g++ 13.1. Why isn't it working?

I can not reproduce the issue in my system. Please make sure all the packages are updated using pacman -Syyu command.

Done it. Even reinstalled the whole thing from scratch. Still doesn't work. @Biswa96

  • Where are you running g++ command?
  • What is the output of which g++.exe command?
  • Did you check if antivirus is not messing up the msys2 installation?
  • Did you check if ASLR is not forcefully enabled for all executables?

Note that your example will depend on the following DLLs, so make sure they are findable:

$ ntldd -R main.exe  | grep mingw64
        libstdc++-6.dll => C:\msys64\mingw64\bin\libstdc++-6.dll (0x000002677ac20000)
         libgcc_s_seh-1.dll => C:\msys64\mingw64\bin\libgcc_s_seh-1.dll (0x000002677a9f0000)
         libwinpthread-1.dll => C:\msys64\mingw64\bin\libwinpthread-1.dll (0x000002677a780000)

@lazka if i run this $ ntldd -R main.exe | grep mingw64 it shows nothing.
For both the corrupt and the working executable(created with an older version of mingw(native) version-12.3.0

However, I manually found the files using Windows Explorer, and they are in the mentioned directory.

This issue can not be reproduced and only happens in your system. The same gcc compiler toolchain is being used to compile mingw packages.

@Biswa96 Biswa96 closed this as not planned Won't fix, can't repro, duplicate, stale Aug 3, 2023

Apparently, as I installed Qt, it installed it's own version of mingw64 which was messing with my default g++ installation. Uninstalling Qt fixed it.
