Running Console App On Server Without Sudo Rights

EverydayDiesel

Hello,

I am trying to evaluate if qt will work for my situation. I basically have 2 machines. 1 is a dev machine and the other is a server. On the server I do not have sudo.

I am trying to write a console app which works fine on the dev machine.

When I move it to the server I get this error

$ ./test2
./test2: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./test2)

The question is, how can I get this to run without installing something on the server? Is it possible to package and statically link everything or something similar? I am ok with multiple files, I just cant install qt on the server due to lack of sudo rights.

Thanks in advance for any help you can give.

Im not partial to any C++ compiler, I just need it to work on both machines :)

you can package your application with programs like linuxdeployqt, it bundles shared libraries into a single executable and it will be self contained, so you won't need to install Qt (and other app dependencies) on the server.

./test2: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./test2)

It seems something is wrong with your glibc version. try: ldd --version on your machines.
Here is what I guess:
Your server's glibc is older than your dev machine and as far as I know you should downgrade your dev machine's glibc(probably by downgrading it's OS)
