Kindly check
Have you tried removing -Werror from your compilation flags? Or if you're not sure adding -Wno-error to compilation flags and try compiling again?
I am rebuilding the RPM from the SRPM from
http://nginx.org/packages/centos/9/x86_64/RPMS/nginx-1.22.0-1.el9.ngx.x86_64.rpm
I have now put
export CFLAGS=-Wno-error
before the rpmbuild.
I am waiting for the result as the compilation is taking longer than usual.
Make sure rpmbuild respects the CFLAGS environment variable.

I tried with latest version 0.2.0, still the same issue on el9:

Hi, Thanks for reporting. It seems that the same issue in #223
Can you share the SPECS/nginx.spec like this?
https://github.com/hnakamur/nginx-rpm/blob/main/SPECS/nginx.spec#L298
#223 also said that it can ignore the error with --with-cc-opt=-Wno-stringop-overread.
./configure \
...
--add-module=/some/where/nginx_module_vts
...
--with-cc-opt="%{optflags} $(pcre-config --cflags) -Wno-stringop-overread"
Please consider adding the options if you can.
@fossee-sysad @karljohns0n @u5surf
I fixed where I think the problem is occurring. please check.

Thanks @vozlt, it compiles fine now without using -Wno-stringop-overread
