Required libraries for 64-bit machines

If you are running a 64-bit version of Ubuntu, you need to install some 32-bit
libraries with the following command:

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386

If you are running 64-bit Fedora, the command is:

sudo yum install zlib.i686 ncurses-libs.i686 bzip2-libs.i686
bash-5.1$ grep MemTotal /proc/meminfo
MemTotal: 3913176 kB
bash-5.1$ free -h | awk -v OFS='\t' 'NR==3{print $1, $2}'
Swap: 8.0Gi
bash-5.1$

The hardware limitations do not allocate for installing the emulator.

bash-5.1$ sed -n '6,19p' /var/lib/sbopkg/SBo/15.0/system/wine/README.MULTILIB
https://docs.slackware.com/slackware:multilib

A script that rsyncs with alienBOB's repo and installs the multilib
packages which can be found here:
https://slackware.uk/~dive/scripts/alien-multilib-rsync.sh

Be sure to read the short instructions at the top. If you use slackpkg
then you will also want to blacklist his packages in
/etc/slackpkg/blacklist:

[0-9]+alien
[0-9]+compat32

Slackware 15.0 is the last release that needs separate (alien's) multilib
versions of gcc and glibc.
On August 30, 2024, Pat Volkerding added multilib capability to Slackware's
own gcc and glibc packages. What you still need to add to your system is
the collection of -compat32 packages.
bash-5.1$

https://gcc.gnu.org/install/configure.html

The multilib (alien's) gcc will pass the --hash-style=gnu option to the linker for all final links.

The slackware-current gcc is not configured with the option --with-linker-hash-style=choice.

rsync over TLS

rsync does by itself not support TLS, but we can simply outsource TLS handling
to the openssl s_client. The rsync authors have made a short script to do
exactly that. This is how you use it to get a listing from our server:

wget https://download.samba.org/pub/rsync/openssl-rsync
chmod +x openssl-rsync
rsync --rsh=./openssl-rsync rsync://mirrors.dotsrc.org

It is wise to read the script before executing it blindly.
