[GCC for C ++] compilation options-ide masks the sky

Single source file to Executable
$ G ++ helloworld. cpp [-O helloworld]
Compile C ++ with GCC:
$ GCC helloworld. cpp-lstdc ++-O helloworld
_____________________________________________
Multiple source files to Executable
$ G ++ hellospeak. cpp speak. cpp-O hellospeak
_____________________________________________
Source file to object file
$ G ++-C hellospeak. cpp-O hspk1.o
$ G ++-C speak. cpp-O hspk2.o
$ G ++ heat k1.o heat k2.o-O hellospeak
-C: generate the. o file
____________________________________________
Preprocessing
$ G ++-e helloworld. cpp [-O helloworld. II]
-E: Only pre-processing files are generated.
____________________________________________
Generating assembly language
$ G ++-s helloworld. cpp
-S: generate only assembly files
____________________________________________
Creating a static library
Generate a. o file. Ar is a file.
$ G ++-C sayhello. cpp
$ G ++-C say. cpp
$ Ar-r libsay. A sayhello. o say. o
Use static library
$ G ++ saymain. cpp libsay. A-O saymain
_____________________________________________
Creating a shared library
Generate the. o file and generate the. So file.
$ G ++-C-FPIC average. cpp
$ Gcc-shared average. O-o average. So
Or:
$ G ++-FPIC-shared average. cpp-O average. So

Libraries
The standard C ++ library is libstdc ++. A, which contains all the standard C ++ programs.
