error: 'stoi' is not a member of 'std'

[WhatIf]

I'm trying to use a class I wrote and tested as plain c++ program in a Qt app but I'm running through problems. I was able to fix one but don't seem to find the solution to the other problem.

return std::stoi(recordCount);

the above line is producing error: 'stoi' is not a member of 'std'

recordCount is a string defined as

std::string recordCount;

By the way, I compiled and ran the plain c++ program using Qt Creator successfully.

hi
hmm, it should be ?
http://www.cplusplus.com/reference/string/stoi/
maybe try the Example ?

[sandy.martel23]

std::stoi() is c++11

CONFIG += c++11 ?

@sandy.martel23
good catch!
if using mingw compiler u need to add
CONFIG += c++11 to
your pro file as c++11 support is not enabled pr default for this compiler.

Thank you very much guys :)

CONFIG += c++11 is what was missing. It was included automatically in the plain c++ program by Qt Creator but not for the gui program.
