GCC G++ 参数(国外英文资料).doc

GCC G++ 参数(国外英文资料) GCC and g + + are gnus c c + + compilers, GCC/g + +, which takes four steps to execute the compilation Preprocessing, generation. I files [preprocessor CPP] The pre-processed files will not be converted into assembly language, generating the file. There is an assembly that becomes the target code (machine code) generation.o file [assembler as] Connect to the target code and generate the executable program [link to ld] [details of the parameters] - x language filename The language used in the setting of the file will invalidate the suffix name, which will be valid for many later The name is.c, and the suffix of c + + is.c or.cpp, if you are very individual, determine the suffix of your c code file The name is.pig haha, so youre going to use this parameter, and this parameter works for the name of the file behind him, unless its there The use of the next parameter. The parameters that can be used have the following ` c , ` objective - c , ` c - the header , ` c + +, ` CPP - output and ` assembler, and ` a Ssembler - with - CPP . When you see English, you should understand it. Examples: GCC - x, hello. Pig None - x filename Turn off the last option, which is to allow GCC to automatically identify the file type according to the filename suffix Examples: Cgs-x, hello.pig-x - c It only activates preprocessing, compilation, and assembly, which is that he only makes the program obj files Examples: GCC - c hello.c Hes going to generate.os obj file The -s To activate preprocessing and compilation only means compiling files into assembly code. Example usage GCC - S hello. C He will generate the.s assembly code, and you can view it with a text editor - E Only activation preprocessing, this doesnt generate the file, you need to redirect it to an output file. Examples: Hello. GCC - E hello. C pianoapan. TXT GCC - E hello. C | more Take your time, and a hello word will also be processed into 800 lines of code -o Set the target name, and by default, the file co
