Hi,

pgAgent throws the warnings below while compiling it on Fedora 32, which uses GCC 10. Can you please take a look?

Thanks! Devrim

Hi Devrim,

I have tried with gcc 10.1 on Ubuntu and I checked the logs but did not find any warning. Below is my setup and logs during pgAgent compilation.
Is there any specific gcc 10.X version ? Let me know, I can set up and send a patch.
