This article tests three compilers, namely VC, mingw, and GCC, in 32-bit and 64-bit modes. In six cases, the predefined macro values related to 64-bit programming are used. It is of reference significance for cross-platform programming.   Agner fog

GSL is an open-source mathematical function library written in C/C ++. It is very popular and practical. We use cmake to create Makefile files. If you are familiar with cmake, you should know that cmake can directly generate engineering files for

By using conditional judgment, you can have make to select different execution branches depending on the runtime's circumstances. A conditional expression can be a value of a comparison variable, or a value that compares variables and constants.
