Hi I have wrote a program in C++ in Netbeans on Macintosh that uses these these includes - iostream,fstream, string & cstdlib. The program compiles fine in Netbeans but I need to compile and run it with gcc because I need to pass an Image File to the program in terminal.
When I try to compile I get the error below and to be honest I am completely lost as to what is going on. It seems there is an issue with the namespace? Anyone able to help?
Thanks!
