Re: [KOS] trouble with standard library

Compile and link with kos-c++ in your Makefile, rather than $KOS_CC or whatever it is your makefile is currently using. The issue here is that you’re not linking in the standard C++ library at all, which causes problems if you try to use any of it. - Lawrence > On Dec 29, 2016, at 10:24 PM, Nathan Meier <gro...@gm...> wrote: > > So I'm in the process of converting code over from c to c++.(The code was based of the PNG example.) > > Currently I'm trying to use functions from the standard library like #include<vector>, #include<string> and #include<fstream>. > > When I try and compile the program in Cygwin.
