Answer 1

gcc and g++ are compiler-drivers of the GNU Compiler Collection (which was once upon a time just the GNU C Compiler ).

(gcc和g++是GNU Compiler Collection的编译器驱动程序（曾经只是GNU C编译器 ）。)

Even though they automatically determine which backends ( cc1 cc1plus ...) to call depending on the file-type, unless overridden with -x language , they have some differences.

(即使它们根据文件类型自动确定调用哪些后端（ cc1 cc1plus ...），除非用-x language覆盖，否则它们会有一些差异。)

The probably most important difference in their defaults is which libraries they link against automatically.

(默认情况下可能最重要的区别是它们自动链接的库。)

According to GCC's online documentation link options and how g++ is invoked , g++ is equivalent to gcc -xc++ -lstdc++ -shared-libgcc (the 1st is a compiler option, the 2nd two are linker options).

(根据GCC的在线文档链接选项以及如何调用 g++ ， g++等同于gcc -xc++ -lstdc++ -shared-libgcc （第一个是编译器选项，第二个是链接器选项）。)

This can be checked by running both with the -v option (it displays the backend toolchain commands being run).

(这可以通过使用-v选项运行来检查（它显示正在运行的后端工具链命令）。)
