Hi, there.

Here is a patch for using pcre-config to set ngx\_feature\_path and  
ngx\_feature\_libs.  
I need this since I would like to use pcre 8.32 built from source and  
installed in /opt/lib64/libpcre.so.1.

Could you review this patch?  
Thanks

I don’t think that “`pcre-config --prefix`/include” is a good  
aproach.

Have you considered just using

./configure --with-cc-opt=“-I/path/to/include”  
–with-ld-opt=“-L/path/to/lib” …

?

Hi!

In my case  
./configure --with-pcre-jit --with-cc-opt=“-I/opt/include”  
–with-ld-opt=“-L/opt/lib64 -lpcre”  
does it!

Now it is properly configured without my patch. I get the following  
output.

- using system PCRE library

Thank you very much for your help.
