running on Linux fails: libcrypto.so.1.1

[FlorinAndrei]

On Ubuntu 16.04 - downloaded the sources and compiled.

When launching the wallet app, it throws an error, saying libcrypto.so.1.1 is missing. The closest I have on my system is:

$ find /usr | grep libcrypto.so
/usr/lib/x86_64-linux-gnu/libcrypto.so

If I symlink libcrypto.so.1.1 to the existing .so, the wallet complains again: error loading OpenSSL library function "ECDSA_SIG_get0"

These are the ssl packages on my system:

It would be best if the wallet project could provide statically linked Linux binaries in the Releases section. By static linking, all library components that are required for the wallet to run are included in the executable.

This would be a great workaround for the diversity problem, which makes it so hard to provide an app that works on all Linux distributions. A statically linked binary is self-contained and works just fine as long as the kernel is not extremely old.

The size of the statically linked executable is usually not excessive, since only the library code that is actually needed is included in the file.

You can install it manually from the openssl website. Credit to the guy on stack overflow thread.

wget https://www.openssl.org/source/openssl-1.1.0g.tar.gz
tar xzvf openssl-1.1.0g.tar.gz
cd openssl-1.1.0g
./config -Wl,--enable-new-dtags,-rpath,'$(LIBRPATH)'
sudo make
sudo make install

Used the above to get the wallet running about 10 min ago.

Sure, but that's a stop-gap measure. You can't ask all users to compile custom openssl version just to install a wallet.
