如何在Eclipse IDE中將編譯器從C更改爲C++？

Question

我的項目是C和C++共享庫（我在Linux平臺上使用Eclipse IDE）。項目採用C編譯器（GCC）的默認設置。任何人都可以爲我的項目建議如何將編譯器從C更改爲C++。

Answer 1

GCC可以編譯C和C++源文件。它使用文件擴展名來確定它是否應該編譯爲C或C++。

C++ source files conventionally use one of the suffixes ‘.C’, ‘.cc’, ‘.cpp’, ‘.CPP’, ‘.c++’, ‘.cp’, or ‘.cxx’; C++ header files often use ‘.hh’, ‘.hpp’, ‘.H’, or (for shared template code) ‘.tcc’; and preprocessed C++ files use the suffix ‘.ii’. GCC recognizes files with these names and compiles them as C++ programs even if you call the compiler the same way as for compiling C programs (usually with the name gcc).

Answer 2

GCC：GNU編譯器集合

GCC：GNU C編譯器G ++：GNU C++編譯器

的主要區別：

gcc will compile: .c/.cpp files as C and C++ respectively. 

g++ will compile: .c/.cpp files but they will all be treated as C++ files. 

Also if you use g++ to link the object files it automatically links in the std C++ libraries (gcc does not do this).
