undefined reference to `std::ios_base::Init::Init()'

Question

I write this code to read 3 files, TM is the size of square matrix, LER the No. of rows of an array and from last value define a non-square matrix of (ler/2)*2

Then.

Answer 1

Most of these linker errors occur because of missing libraries.

I added the libstdc++.6.dylib in my Project->Targets->Build Phases-> Link Binary With Libraries.

That solved it for me on Xcode 6.3.2 for iOS 8.3

Cheers!
