three stages. Stage 1 and stage 2 binaries are deleted as soon as they are no longer needed. Typically
this building process will do the following:
• Build some basic tools like bison, gperf and so on. These tools are necessary to
continue the compilation process.
• Build target tools like gas, ld, binutils and so on.
• Perform a three-stage bootstrap of the compiler.
• Perform comparison of stage 2 and stage 3.
• Build run-time libraries.
• Remove unnecessary files.
You should have enough disk space to build GCC. If you are short of disk space, you can
use the bootstrap-lean option on the command line instead of bootstrap.
3.2.2.4 Final Install
The final installation process is necessary to move GCC binaries under the directory used
as a prefix during the configure script execution. We have used /opt/gcc-3.0.4 as the
prefix directory. Executing the following command in /gcc3/objdir will move GCC binaries
in a tree structure under /opt/gcc-3.0.4.
make install
A typical directory tree after installation is shown below.
