# This is supposed to be a TOOLCHAIN file for compiling a 32-bit version
# on 64-bit Linux, but that doesn't work  somehow. The work around is to
# configure using
#
#     cmake -DSWIPL_M32=ON ...
#
# Note that all packages, gcc and g++ need to be installed for i386,
# e.g.
#
#     apt install gcc-multilib g++-multilib

# apt install \
#	libarchive-dev:i386 libc6-dev:i386 libc6-dev-i386 \
#	libdb-dev:i386 libedit-dev:i386 libgmp-dev:i386 \
#	libice-dev:i386 libjpeg-dev:i386 libjpeg8-dev:i386 \
#	libncurses5-dev:i386 libossp-uuid-dev:i386 \
#	libpcre2-dev:i386 libssl1.0-dev:i386 \
