What files does gcc need?

The number of files required by gcc-general Linux technology-Linux programming and kernel information. The following is a detailed description. I want to put a gcc system that can compile the basic C program on a small system, so that I can use the minimum system or compile some small programs if necessary, so I did the following work:

Copied the following files:
/Usr/bin/gcc -- gcc execution Program

/Usr/lib/gcc/i386-pc-linux-gnu/gcc_version/* -- gcc corresponds to the C language compiler, for example, cc1plus, collect2 and so on, there are some. o files

/Usr/lib/libgcc_s.so. This function is not clear and seems to be used for output after compilation. It plays a role in the link stage.

/Usr/include/header file. You can use rpm-ql glibc-devel | grep "\. h "find out, this is about m, it is estimated that there is still redundancy, because the glibc-2.3.5 source code under the include directory only 8 xxKBs

/Usr/bin/ld and/usr/bin/as, compile the compiler and linker, and support its running. so file, which belongs to the binutils package, not the content of the gcc package

/Usr/lib/crt ?. O, including crt1.o, crti. o, and crtn. o. This is the link target code corresponding to the glibc library and does not belong to the gcc package.

/Usr/lib/libc. so and/usr/lib/libc_nonshared.a. The former is a pure text configuration description file, and the latter is the code of some hard-linked functions.

The affiliation of some summarized files:
Related to gcc versions include gcc, all files in the same directory as cc1plus and cc1plus, and libgcc_s.so.

Related to binutils: as and ld and library files supporting them

Glibc versions are involved in:/usr/lib/crt ?. O and/usr/lib/libc. so, libc_nonshared.a, And the header files under/usr/include corresponding to glibc

The final statistics show that all files use approximately 26MBs space, which is still very large. However, you can also copy and use gdb.
