Issue with GCC RPM Package Installation:

Issue with GCC RPM Package Installation:

# rpm -ivh gcc-4.4.4-13.el6.x86_64.rpm

Install glibc-header:

Install cpp package:(it will fail)

# rpm -ivh cpp-4.4.4-13.el6.x86_64.rpm
warning: cpp-4.4.4-13.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY
error: Failed dependencies:
 libmpfr.so.1()(64bit) is needed by cpp-4.4.4-13.el6.x86_64

As it is asking for libmpfr.so, we need to install mpfr RPM:

# rpm -ivh mpfr-2.4.1-6.el6.x86_64.rpm
warning: mpfr-2.4.1-6.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

Install cloog-ppl RPM:(to correct further issues)

# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
warning: cloog-ppl-0.15.7-1.2.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY
error: Failed dependencies:
 libppl.so.7()(64bit) is needed by cloog-ppl-0.15.7-1.2.el6.x86_64
 libppl_c.so.2()(64bit) is needed by cloog-ppl-0.15.7-1.2.el6.x86_64

As it needs libppl.so, install ppl RPM:

# rpm -ivh ppl-0.10.2-11.el6.x86_64.rpm
warning: ppl-0.10.2-11.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

Install cloog-ppl RPM:

# rpm -ivh cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
warning: cloog-ppl-0.15.7-1.2.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

Install cpp package:(it would be successful)

# rpm -ivh cpp-4.4.4-13.el6.x86_64.rpm
warning: cpp-4.4.4-13.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY

Now, try with GCC Installation:

# rpm -ivh gcc-4.4.4-13.el6.x86_64.rpm
warning: gcc-4.4.4-13.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID ec551f03: NOKEY
