Executable error : 0xc0000139 when merging std c++ code in qt application

[infomath]

Hi! I have a simple application in qt and I'm trying to link some code that I have to it. However, when I'm merging the files in the project, it compiles, but I get an error at startup. When I try to debug it, I get a pop up message telling me Executable error : During startup program exited with code 0xc0000139.

I searched in google and I found that it's probably a dll error. I've got to admit, I don't really know how libraries work so I'm a bit confused.

I trying to import the code functions by functions to see what's working and what is producing the error. A simple function like this :


void descendanceOf(std::vector< std::list<int> >& tree, int node){
std::list<int> descendance;
descendance.push_back(4);
}


produces an error, but I function like this :


bool isFatherOf(const std::vector < std::list < int > >& tree, int node1, int node2){
for(std::list<int>::const_iterator it = tree[node1].begin(); it != tree[node1].end(); it++){
if((*it) == node2){
return true;
}
}
return false;
}

works perfectly fine. I'm confused. At first I though it has something to do with the std library, but both functions use it.

Thank you for your help!

Error code 0xc0000139 is issued when windows is failing to load a dll file.
The necessary dll files need to run your programm should be accessible by the OS.
Put them either in the windows/system32 or in the folder where your exe is stored.
If you do not know which dll, use dependency walker from Microsoft.

Thank you! I downloaded Dependancy Walker and I realized that libstdc++-6.dll was missing. I got other problems after...I decided to uninstall qt and delete minGW and other sources of possible conflicts and start all over again.
