Non-Multilib

Compile the package:

sed -i '/PROTO.*readline/d' bc/scan.l &&
sed -i '/flex -I8/s/8//' configure &&
sed -i '/stdlib/a #include <string.h>' lib/number.c &&
sed -i 's/program.*save/static &/' bc/load.c &&
./configure --prefix=/usr --with-readline &&
make

Install the package

make install

Command Explanations

sed -i '/PROTO.*readline/d' bc/scan.l: This command fixes the Readline library call.

sed -i '/flex -I8/s/8//' configure: This command fixes the Flex invocation.

sed -i '/stdlib/a #include <string.h>' lib/number.c: This command inserts a missing header.

sed -i 's/program.*save/static &/' bc/load.c: This command fixes a segfault when running bc with bc -l.

--with-readline: This option enables Readline support in interactive mode.

Multilib

This package does not provide any libraries so only one installation is needed.
