Installing tar, pcre, grep

Continue to build from /tools (remember to have the PATH set as described in Recompiling)

tar

tar xf tar-1.26.tar.gz
cd tar-1.26
./configure --prefix=/tools
make -j 8

build will fail. remove _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead"); from gnu/stdio.h

make -j 8
make install
cd ..

pcre

tar xf pcre-8.32.tar.gz
cd pcre-8.32
./configure --prefix=/tools
make -j 8
make install
cd ..

grep

tar xf grep-2.7.tar.gz 
cd grep-2.7
./configure --prefix=/tools
make -j 12
make install
cd ..

We are now ready for next step
