Trouble getting Unity to start in Fedora 23

Everytime I try to run the ./Unity executable I get the following error

./Unity: /opt/unity/unity-editor-5.1.0f3/Editor/Data/Tools/libgpg-error.so.0: no version information available (required by /lib64/libgcrypt.so.20)
./Unity: relocation error: /lib64/libgcrypt.so.20: symbol gpg_err_set_errno, version GPG_ERROR_1.0 not defined in file libgpg-error.so.0 with link time reference


I can't see anyone else getting this error so I have no idea what the problem is. Any ideas?

 

Ran into the same error on Fedora 23 after using the platform-agnostic installer.

 

Figured it out. Remove the /opt/unity/unity-editor-5.1.0f3/Editor/Data/Tools/libgpg-error.so.0 file and it should work. I believe it was due to a system library conflict.

 

Thanks, it works for me!
Under "Tools" folder, I removed libgcrypt.so.11 and libgpg-error.so.0, since my fedora setup already has these files installed as rpm packages.

 

Hello,
I'm also running Fedora 23 and I struggle to launch Unity too.
My issue however seems to differ from yours.
I've downloaded the last 5.4 beta, and each time I try to launch it, all I got is the splash screen, and a blank window entitled "recent".
I got no error message, but I can see the unity process is taking 100% of the CPU.
Any ideas of the issue ?

 

I have had the same issue you described even though I was on Debian (Jessie). You can get a look at my solution here: http://forum.unity3d.com/threads/unity-editor-for-linux-stalls-in-debian-jessie.401483/#post-2641956. My advice would be to install some packages such as npm and standard development libraries. I don't know if Fedora is similar to Debian but I have pasted in the provided link the additional packages I have installed to get the editor working (the "other distributions" editor works as well as the Ubuntu specific one). Good luck!

 

Well done !
You nailed it with the npm packages. That was the missing dependency.
Too bad the unity script installer doesn't verify that, because we have no information to find out what's going on.
Anyway it's now working, but it's still eating 100% of one of my CPU core.
Hopefully they will fix that soon.

 

Just a friendly reminder for my "Unity3d on Fedora" thread.

Maybe you can find solutions for current and future problems.

 

I tested with Fedora 24 alpha the last 5.4.0b18 version type .sh .
I install Mono , Mono develop, libpq , nodejs-npm*, postgresql-libs, postgresql, used command mkdir ~/.local/share/unity3d/Packages .The Unity editor interface working well.
