I am trying to declare a vector pointer, and an ifstream pointer in a class that I plan to use to read binary files. I have heard from someone that using #include in header is often not best (not sure why), that it is better to use "class <name>", and then in the *.cpp file do the #include <name> call.
I have tried doing that in my code but it doesn't work. I have tried this with some qt classes before and it works.
I get this error:Code:// #include <vector> // #include <fstream> class std::vector<uint32_t>; class std::fstream;
Code:g++ -c -Wall main.cpp -o main.o error: 'vector' is not a template error: 'uint32_t' was not declared in this scope error: 'vector' in namespace 'std' does not name a type error: 'fstream' in namespace 'std' does not name a type error: 'uint32_t' does not name a type error: using-declaration for non-member at class scope error: expected ';' before '*' token make: *** [main.o] Error 1
