Running EAGLE 6 on Linux Mint 20.3

Download the 32-bit OpenSSL libraries: https://mirror.sit.fraunhofer.de/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu5.10_i386.deb

Unpack usr/lib/i386-linux-gnu/libcrypto.so.1.0.0 and usr/lib/i386-linux-gnu/libssl.so.1.0.0 from the DEB file (use the Archive Manager).

Put the shared libraries and the EAGLE installer into the same directory and install EAGLE:

chmod +x eagle-lin-6.6.0.run
sudo LD_LIBRARY_PATH=. ./eagle-lin-6.6.0.run /opt

Copy the libraries into place:

cp libcrypto.so.* libssl.so.* /opt/eagle-6.6.0/bin
cd /opt/eagle-6.6.0/bin
sudo mv eagle eagle.real

Create /opt/eagle-6.6.0/bin/eagle with the following contents:

eagle-run.sh

#!/bin/bash
 
export LD_LIBRARY_PATH=/opt/eagle-6.6.0/bin
/opt/eagle-6.6.0/bin/eagle.real $@

Run the /opt/eagle-6.6.0/bin/eagle shell script as root (under sudo) and install the licence.
