# not, %build aborts rather than producing a module nginx refuses to load.

# the SRPM: listing only the selected one fails the el10 rebuild on a missing
# source, since the SRPM is built once, with %%{rhel} undefined.

# nginx is only needed to verify at build time that we compile against the
# version that is actually installed. --with-compat means we do not have to
# replicate the distro's configure flags, so none of its optional deps
# (gd, libxslt, perl, gperftools) are needed here.

# nginx switched to PCRE2 in 1.21.5, so 1.20.1 needs PCRE1. Both are pulled in
# where both exist, so an overridden nginx_version still finds its headers.
# EL10 dropped PCRE1 altogether.

%description
GeoIP2 module for nginx. Looks up the geographic location of a client address
in a MaxMind GeoIP2 (.mmdb) database and exposes the result as nginx variables.

%changelog
* Fri Jul 10 2026 Siarhei Chystsiakou <brestows@gmail.com> - 3.4-3
- Build against --with-compat instead of scraping `nginx -V`, which ran outside
  the buildroot and forced a long list of unrelated BuildRequires
- Pick the nginx version per EL release (8/9/10) and fail early on a mismatch
- Require nginx(abi) rather than an exact nginx NEVR
- Use pcre2-devel on EL9+; EL10 no longer ships PCRE1

* Mon Jan 23 2023 brestows <brestows@gmail.com> - 3.4-2
- Compiled for nginx base version 1.20.1
