Linux gcc Compiler installation __linux

GCC (GNU Compiler Collection GNU Compilation Tool Collection) enables the C, C + +, and Java languages to be compiled from the source code into binary code, which is a tool.
Software dependencies:
The author develops a software, needs a function library, this function library already exists in the machine B software of the author at that time, so that a software does not need to repeat development, direct call B software corresponding function library can. If someone else buys a software, they will be prompted to install the B software (the purchaser's machine does not yet have B software).
When a software is installed on the purchaser's machine, it is prompted to install the B software first.
The process of installing a software must first install the B software, known as a to B-dependent.
Later a software on any machine installed on the B software will form a dependency.
"A relies on B-dependent C-dependent d"
①a software needs to install BCD and other dependent software before installation:
A------>b------->c-------->d (D->c->b->a is the installation order)
② uninstall C software also need to uninstall AB and other software first:
C------->b-------->a (A->b->c is uninstall order)

GCC Software Installation dependencies:
gcc-4.4.7 (c-language source GCC compiled)
CLOOG-PPL (software dependencies)
Libppl.so.7 (module dependent)
Libppl_c.so.2 (module dependent)
(above two dependencies is the module dependence, directly installs the module the software ppl can)
Cpp

Libmpfr.so.1

(The above dependency is module dependent, install MPFR software can)
