nginx-mainline-mod-lua build failed caused by quote marks in `nginx -V`

My nginx -V outputs

nginx version: nginx/1.25.0

Apparently, the quote marks in --with-cc-opt get stripped when going through the printf line in https://github.com/ahmubashshir/pkgbuilds/blob/7b6b4e024ca1a04825e5ce7e023d9a9ac4d23c0c/nginx-mainline-mod-lua/PKGBUILD#L37-L42 and confused nginx/configure.

A quick workaround is to change this block to

    nginx -V 2>&1 |
        grep -o -- '--prefix=.*$' |
        sed '/--with-ld-opt=/{s/-Wl,/\0-E,/;s/-Wl,/-lpcre \0/}' |
        xargs /usr/src/nginx/configure \
            --add-dynamic-module=../$_modname-nginx-module-$pkgver

Can you try this patch?

Yes, it works!

The regex in https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=nginx-mainline-mod-http-xslt-filter also works:

sed -nE 's/^configure arguments: ([^\n]*)$/\1/p' |
sed -nE 's/([^'"'"' \t\n]+('"'"'([^'"'"'\]|\\'"'"'?)*'"'"'|"([^"\\]|\\"?)*")?) ?/\1\n/gp')
