# EL9 ships nginx 1.20.1 as a plain package and EL10 ships 1.26.3. EL8 ships
# nginx only as a module stream, defaulting to 1.14 -- which does not even carry
# an nginx(abi) provide -- so the copr chroot needs nginx:1.20 enabled. If it is
# not, %build aborts rather than producing a module nginx refuses to load.

# 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.

%changelog
* Fri Jul 10 2026 Siarhei Chystsiakou <brestows@gmail.com> - 0.34-5
- 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
- Drop the unused NGINX_COMPILED_FLAGS/BASE_CONFIGURE_ARGS macro block
- Add %%{?dist} to Release

* Fri Jul 01 2022 brestows <brestows@gmail.com> - 0.34-4

* Wed Jun 17 2020 Dzmitry Stremkouski <mitroko@gmail.com> - 0.33-1
