Static linking on OpenSUSE for deployment on Ubuntu - what to link?

**bloks** · 11th June 2014, 15:29

After successfully linking my application to the static library in OpenSUSE, I copied it over to a qt-less Ubuntu machine only to find that xkbcommon and EGL are missing from the executable.

I run ldd on my application in OpenSUSE, and this is what I get:

Qt Code:

Am I supposed to statically link all of these before deployment?

If you want your executable to work on top of just the kernel, without any library what so ever present, then yes, you'll have to link all libraries statically into that executable.

Is there a resource somewhere that compares the Ubuntu and OpenSUSE libraries?

I'm concerned about linking libraries that potentially could break the program, such as X11, and linking libraries that makes other ones redundant.
