c++ - GCC: How to enable specific compilation warnings and disable rest

Question

I am working witn gcc verisons 5.4.0 and 9.2.0. While compiling C/CPP code, I am unable to turn on specific warning message and disable all of the rest. I wanted to show missing return statement warning as errors and want to disable all other possible warnings.

For this I am running my gcc command with arguments as: -Werror=return-type -w. But looks like if we used -w then gcc not ownering other argument. Also tried running with arguments as: -Werror=return-type -w -Wreturn-type This also tunring off all the warnings even return-type warning. Is there any way I could enable warning generated by -Wreturn-type and disable rest of others.
