Unigine Superposition on Debian?


I have googled around and the results suggest that jutsby linking a library I may be able to solve it but, alas, I don't have that library.
The error I see is:
Code:
qt.network.ssl: QSslSocket: cannot resolve CRYPTO_num_locks
I'm sure I'm jsut missing something obvious here, has anyone got this running on Debian?

I guess you've looked for the library on the Debian repositories? What is the library you're missing?

BTW, this might be helpful, in case you haven't tried it already.

You have probably already seen this in your googling: http://www.geeks3d.com/20170412/unig...#comment-86028

You might check to see if it has been reported: https://developer.unigine.com/forum/
I couldn't view the bug reports without signing up.

Thanks for the replies. Odiseo77: I've seen a solution which involves creating a simlink in the name of the old SSL library pointing to the new one but I can't find the file I need to link to either on my system or looking at the Debian package search site. Sadly I can't recall the name and I'm not finding it in my google results. I think it's something like lib-openssl1.

Compiling and running the following on my sid system:
Code:
#include <QSslSocket>
#include <QDebug>

int main() {
    qDebug() << "Qt Version:" << qVersion();
    qDebug() << QSslSocket::sslLibraryVersionString();
}
I get this output:
Quote:
Qt Version: 5.7.1
qt.network.ssl: QSslSocket: cannot resolve SSLv3_client_method
qt.network.ssl: QSslSocket: cannot resolve SSLv3_server_method
"OpenSSL 1.0.2k 26 Jan 2017"
Code:
~$ openssl version
OpenSSL 1.1.0e  16 Feb 2017
Perhaps OpenSSL 1.0.2 is what you need? https://packages.debian.org/sid/libssl1.0-dev

HTH

According to the link I posted before, you need libssl1.0-dev, which sounds similar to the library name you wrote. (It's in the repositories, so you only have to install it with apt-get).

Thanks all, installing libssl1.0-dev is, indeed, all I needed to do. I think I was going on a wild goose chase after seeing mention of linking to one of the .so files from the current libssl then not being able to find it.
Happy to be marking this solved, and on with my playing...

Darn, I now have to mark as unsolved because, while the menu opens, the benchmark and game just crash.
May be due to my having two monitors (I think this because the cursor becomes locked in the monitor the program wasn't run from).
Though the install issue is resolved I'll leave unresolved in case anybody knows anything else I may be missing.

Maybe you can try to run it from a terminal window to see if it throws any relevant messages/errors. Also, if you believe this is caused by using two monitors, you can try using one monitor temporarily to confirm/discard this.

Nothing helpful in the terminal window, might give it a go with one monitor but it's the kind of thing I don't like to do as it's tough enough getting anything to work properly with two monitors these days as it is and I fear any changes may end up with lots more work getting everything working again (I am, perhaps, being a little over-dramatic but, really, everything's been a little broken on two monitors for ages now and is getting worse).

Fedora provides compatibility ssl-1.0 packages, for other distros you probably have to build one from source. After that create links libssl.so and libcrypto.so pointing to corresponding ssl-1.0 libraries in bin/qt/lib subdirectory of Superposition installation. Works just fine.

OK so, finally, I can mark this as solved. It took my buying and installing another SSD an installing Sid fresh on that.
Seems that having separate X screen was, indeed, the issue. Now running Superposition in XFCE on a new Sid install.
