Bc First, change an internal script to use sed instead of ed: cat > bc/fix-libmath_h << "EOF" #! /bin/bash sed -e '1 s/^/{"/' \ -e 's/$/",/' \ -e '2,$ s/^/"/' \ -e '$ d' \ -i libmath.h sed -e '$ s/$/0}/' \ -i libmath.h EOF Create temporary symbolic links so the package can find the readline library and confirm that its required libncurses library is available. Even though the libraries are in /tools/lib at this point, the system will use /usr/lib at the end of this chapter. ln -sv /tools/lib/libncursesw.so.6 /usr/lib/libncursesw.so.6 ln -sfv libncursesw.so.6 /usr/lib/libncurses.so Fix an issue in configure due to missing files in the early stages of LFS: sed -i -e '/flex/s/as_fn_error/: ;; # &/' configure Prepare Bc for compilation: ./configure --prefix=/usr \ --with-readline \ --mandir=/usr/share/man \ --infodir=/usr/share/info --with-readline This option tells Bc to use the readline library that is already installed on the system rather than using its own readline version. Compile the package: make To test bc, run the commands below. There is quite a bit of output, so you may want to redirect it to a file. There are a very small percentage of tests (10 of 12,144) that will indicate a round off error at the last digit. echo "quit" | ./bc/bc -l Test/checklib.b Install the package: make install Installed programs bc and dc Short Descriptions bc A command line calculator bc dc A reverse-polish command line calculator dc
