A compiler is a program that translates your C++ code to object code, after which it is linked (by the linker) to an executable.
A compiler might emit compile warnings and compile errors.
In the project file, add the following lines:
QMAKE_CXX = gcc
QMAKE_CXXFLAGS = -x c
How to set the C compiler to the C99 standard in Qt Creator?
In the project file, add the following lines:
QMAKE_C = gcc
QMAKE_CFLAGS = -x c -std=c99
- Ideally, a program should be statically type safe [5]
- Compile cleanly at high warning levels [1,3]
- Prefer compile errors to runtime errors [2,4]
