Give command gmake 5. Give command gamke_install Here I am getting the error. /usr/bin/install -c -m 644 'vki_posixtypes-x86-linux.h' '/usr/local/include/valgrind/vki_posixtypes-x86-linux.h' /usr/bin/install: cannot remove `/usr/local/include/valgrind/vki_posixtypes-x86-linux.h': Permission denied gmake[3]: *** [install-incincHEADERS] Error 1 gmake[3]: Leaving directory `/home/rajesh/valgrind-3.1.0/include' gmake[2]: *** [install-am] Error 2 gmake[2]: Leaving directory `/home/rajesh/valgrind-3.1.0/include' gmake[1]: *** [install-recursive] Error 1 gmake[1]: Leaving directory `/home/rajesh/valgrind-3.1.0' gmake: *** [install] Error 2
