LINUX--GCC Simple usage

GCC is the most commonly used under Linux C compiler, corresponding to the CPP has the corresponding g++ tool, Debug has GDB, but it will not be used.

Personally feel that GCC is really a good thing, can be programmed directly under the gedit and then write a shell script with GCC compiled, no more than some IDE trouble, some of the IDE is not only difficult to use and there will be some inexplicable error. 1. Gcc-o Hello hello.c compiled and linked as an executable file named Hello 2. Gcc-i/usr/include Hello.c/usr/lib/libm.a-i contains the header file, then compiles the link as an executable file, and finally the static library file 3. Gcc-c test1.c test2.c compiled for TEST1.O and TEST2.O 4. AR crv mylib.a test1.o test2.o the. o file into a static library Ranlib MYLIB.A make the library file available to create your own library file do not forget to build the header file 5. Gcc-o test test.c./include/usr/local/xxx.so contains examples of dynamic libraries 6. When the program cannot find the library file, you can change the configuration in/etc/ld.so.conf and then execute ldconfig to take effect. LDD XXX command can query the function library required by the XXX program. More information about GCC can be obtained through the man GCC and info gcc.
