Install Patch by running the following commands:
export CPPFLAGS=-D_GNU_SOURCE && ./configure --prefix=$LFS/usr && unset CPPFLAGS && make LDFLAGS=-static && make install |
CPPFLAGS=-D_GNU_SOURCE: Adding -D_GNU_SOURCE to CPPFLAGS command before we configure patch fixes installation of the package on PPC and m68k platforms (that we know of). It also doesn't hurt compilation on other platforms (such as x86) so we do it by default.
patch
The patch program modifies a file according to a patch file. A patch file usually is a list created by the diff program that contains instructions on how an original file needs to be modified. Patch is used a lot for source code patches since it saves time and space. Imagine a package that is 1MB in size. The next version of that package only has changes in two files of the first version. It can be shipped as an entirely new package of 1MB or just as a patch file of 1KB which will update the first version to make it identical to the second version. So if the first version was downloaded already, a patch file avoids a second large download.
