The Bc package contains an arbitrary precision numeric processing language.
Prepare Bc for compilation:
PREFIX=/usr CC=gcc CFLAGS="-std=c99" ./configure.sh -G -O3
The meaning of the configure options:
CC=gcc
              CFLAGS="-std=c99"
            These parameters specify the compiler and the C standard to use.
-O3
            Specify the optimization to use.
-G
            Omit parts of the test suite that won't work without a GNU bc present.
Compile the package:
make
To test bc, run:
make test
Install the package:
make install
