Installing gcc

Aim:

1)To compile gcc version 4.4.2,
2)To detect simple 'if-else' statements after reading source file c-parser.c of gcc.

3)Generate exception to handle 'if detection'.
4)Use git commands to point out difference made in newer compiled gcc from existing gcc on system.

A) Prerequisite: MPFR Library

1) DOWNLOAD MPFR tar file. It can be downloaded from http://www.mpfr.org/.

2) EXTRACT it in home.
2.1) tar -xvf MPFR-4.2.tar.gz

3) CONFIGURE it and install.
3.1)cd mpfr-4.2
3.2) ./configure
3.3) make
3.4) make install (in root)

B)To compile/install gcc

1) DOWNLOAD gcc-4.4.2 tar ball file. It can be downloaded from ftp://gd.tuwien.ac.at/gnu/gcc/releases/

2) EXTRACT gcc-4.4.2 from tar file.
2.1) mkdir gcc1
2.2) cd gcc1
2.3) tar -xvf gcc-4.4.2.tar.gz
2.4) set srcdir = "/home/swati/gcc1/gcc-4.4.2"
set objdir = "/home/swati/gcc1/gcc-bin"
set insdir = "/home/swati/gcc1//usr/local"
2.5) mkdir -p srcdir
mkdir -p objdir
mkdir -p insdir
2.6) cd objdir

2.7)CONFIGURE : /home/swati/gcc1/gcc-4.4.2/configure --prefix=$insdir
2.8) make bootstrap -j3
2.9) make install (in root)
2.10) cd gcc1
2.11) SELECT NEW INSTALLED gcc: export PATH=$insdir/bin/:$PATH

3) COMPILE this new version gcc1
3.1) gcc hello.c -v
