g++ accepts mostly the same options as gcc. DESCRIPTION top When you invoke GCC, it normally does preprocessing, compilation, assembly and linking. The "overall options" allow you to stop this process at an intermediate stage. For example, the -c option says not to run the linker. Then the output consists of object files output by the assembler.

This flag attempts to use visibility settings to make GCC 's C ++ linkage model compatible with that of Microsoft Visual Studio. The flag makes these changes to GCC 's linkage model: 1. It sets the default visibility to "hidden", like -fvisibility=hidden. 2. Types, but not their members, are not hidden by default. 3.

g++ is a program that calls GCC and treats .c, .h and .i files as C ++ source files instead of C source files unless -x is used, and automatically specifies linking against the C ++ library. This program is also useful when precompiling a C header file with a .h extension for use in C ++ compilations. On many systems, g++ is also installed with ...
