Arch Linux User Repository

I found out that the package pcre is deprecated. Now nginx-mainline is compiled with pcre2, so is this module (https://github.com/openresty/lua-nginx-module/commit/cb83e33e26579788be0fe0282fa5976de6dfa6e3).

I propose the following change:

The latest build is causing failures when starting nginx:

2023/04/18 11:47:46 [emerg] 205360#205360: dlopen() "/usr/lib/nginx/modules/ngx_http_lua_module.so" failed (/usr/lib/nginx/modules/ngx_http_lua_module.so: undefined symbol: pcre_dfa_exec) in /etc/nginx/nginx.conf:4

Reverting to https://aur.archlinux.org/cgit/aur.git/commit/?h=nginx-mainline-mod-lua&id=2402b82cdd1b008e38294aca00ac84202a54efe5 fixes the issue.

I think it's just missing the with-ld-opt=-lpcre option

@FirstAirBender, please create a pr with fix @ https://github.com/ahmubashshir/pkgbuilds

This package should be using the same configure flags used to build nginx-mainline. With the current configuration, it does not support ssl directives such as lua_ssl_trusted_certificate.

Issue was initially raised at https://github.com/openresty/lua-nginx-module/issues/2180, but after the build flags were updated and tested, we can see that the issue is resolved by adding the flags used to build nginx itself, which can retrieved using nginx -V

At the very least, it needs the --with-http_ssl_module flag.

@brauliobo, you need to rebuild all nginx modules each time you update nginx.

$ nginx  sudo nginx -t              
2023/03/12 16:44:49 [emerg] 416729#416729: module "/usr/lib/nginx/modules/ngx_http_lua_module.so" version 1023002 instead of 1023003 in /etc/nginx/nginx.conf:3
nginx: configuration file /etc/nginx/nginx.conf test failed

This doesn't to work at all

I installed luajit-openresty but get the following error:

...
configuring additional dynamic modules
adding module in ../lua-nginx-module-0.10.19
checking for LuaJIT library in /usr/lib and /usr/include/luajit-2.0 (specified by the LUAJIT_LIB and LUAJIT_INC env, with -ldl) ... found
checking for LuaJIT 2.x ... not found
    /usr/src/nginx/configure: error: unsupported LuaJIT version; ngx_http_lua_module requires LuaJIT 2.x.

installing luajit package solves the error, but luajit 2.0 is not recommended by openresty.

I have to apply this patch to keep nginx working...
