Special thanks to nate on #openssl and [R] on #linux on Freenode.
I downloaded Eagle 8.4.1 on my Gentoo box, and untar'ed it in my downloads folder.
I went to run with ./eagle, but it gave me errors about OpenSSL!
Now, I don't like dumping proprietary software all over my hyper-secure ultima-fast uber-reliable system,
so I want to keep Eagle 8.4.1 in it's own folder in ~/Downloads/eagle_-8.4.1/ and just create a shortcut
to the binary in there.
Therefore, the full run command for Eagle is (replace $EAGLEHOME with your extracted directory or set EAGLEHOME equal to it):
LD_LIBRARY_PATH=$EAGLEHOME/lib/ $EAGLEHOME/eagle
This tells eagle to use the pre-compiled shared libraries the vendor supplied and NOT the ones installed on my system (if the vendor, Autodesk, supplied one).
But Autodesk supplied the wrong libssh.so.1.0.0, so we are going to fix that.
First, back theirs up:
mv $EAGLEHOME/lib/libssh.so.1.0.0 $EAGLEHOME/lib/libssh.so.1.0.0.old
mv $EAGLEHOME/lib/libcrypto.so.1.0.0 $EAGLEHOME/lib/libcrypto.so.1.0.0.old
Second, download the proper OpenSSL library:
git clone -b OpenSSL_1_0_2-stable https://github.com/openssl/openssl
Third, move into the directory and run the commands:
cd openssl
./config shared
make
make test
Fourth, copy the new files over:
cp libssl.so.1.0.0 $EAGLEHOME/lib/
cp libcrypto.so.1.0.0 $EAGLEHOME/lib/
and Bingo!
Run the proper run command, and it should work just fine.
