Warning: do NOT run make uninstall on this package if you apply the sed fix to change the libexec directory definition. The uninstall rule in the Makefile file runs a command like rm -rf <libexecdir>/* Since we change the libexec directory to /usr/bin it'll run rm -rf /usr/bin/* When installing Gawk using glibc-2.1.x on your base system, it may be necessary to use a fix to prevent a variable name conflict. The following commands can be used in this case. Note that these commands can also be used for other glibc versions so if you aren't sure, then use the first version. cp awklib/Makefile.in awklib/Makefile.in.backup && sed -e '/^datadir/s/awk/gawk/' \ -e '/^libexecdir/s%/awk%%' awklib/Makefile.in.backup \    > awklib/Makefile.in && export CPPFLAGS=-Dre_max_failures=re_max_failures2 && ./configure --prefix=$LFS/usr --disable-nls \    --libexecdir=$LFS/usr/bin && unset CPPFLAGS && make LDFLAGS=-static && make install If you are using a newer glibc version (2.2.x), you can use the following commands to install Gawk: cp awklib/Makefile.in awklib/Makefile.in.backup && sed -e '/^datadir/s/awk/gawk/' \ -e '/^libexecdir/s%/awk%%' awklib/Makefile.in.backup \    > awklib/Makefile.in && ./configure --prefix=$LFS/usr --disable-nls \    --libexecdir=$LFS/usr/bin && make LDFLAGS=-static && make install
