Can't run on Ubuntu: cannot open shared object file

[s-tikhomirov]

On running the binary on Ubuntu 16.04 LTS I get:

./zec-qt-wallet: error while loading shared libraries: libpng16.so.16: cannot open shared object file: No such file or directory

Thanks for filing the bug. It looks like you need to install libpng16, which you can do with
sudo apt install libpng16-16

I thought it was included by default in Ubuntu, but maybe not. Let me look into a more permanent solution.

@adityapk00 the next error I get is:

./zec-qt-wallet: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by ./zec-qt-wallet)

Possibly it would be helpful to include the full list of dependencies in the Readme.

Thank you for following up. I tried it on a clean 16.04 install, and I think I can see the problem. Give me a couple of hours to get back to you.

The problem is Ubuntu 16.04 doesn't ship with the version of GLIBC needed by the C++14 compiler I'm using. Easiest way is to probably upgrade to a newer OS, but I'm trying to make it compile with an older glibc.

OK, I have a tentative build for Ubuntu 16.04 if you want to try it and let me know:
ubuntu1604-zec-qt-wallet-v0.2.9.tar.gz

[adityapk00]

Side Note: The problem is Ubuntu 16.04 ships with a really old version of GLIBC (2.23), which means zec-qt-wallet needs to be specifically compiled with an older glibc.

Seems to work fine on Ubuntu 16.10 and higher

The problem was a GLIBC 2.25 dependency on getentropy(). Removed this dependency, and now it should work with older distros as well.

Available in v0.3.2 https://t.co/0sIUACVunP
