hi,

i’m trying to build from source on an ubuntu system which has libpcre3  
installed:

tony@quantal:~/Downloads/nginx-1.3.14$ dpkg -l | grep pcre  
ii libpcre3:i386 1:8.30-5ubuntu1 i386 Perl 5 Compatible Regular  
Expression  
Library - runtime files

but i can’t for the life of me get the configure script to resolve to  
this,  
libpcre.so.3 is in /lib/i386-linux-gnu, so i’ve tried:

–with-ld-opt="-L/lib/i386-linux-gnu"

## but still get:

…  
checking for PCRE library … not found  
checking for PCRE library in /usr/local/ … not found  
checking for PCRE library in /usr/include/pcre/ … not found  
checking for PCRE library in /usr/pkg/ … not found  
checking for PCRE library in /opt/local/ … not found

./configure: error: the HTTP rewrite module requires the PCRE library.  
You can either disable the module by using --without-http\_rewrite\_module  
option, or install the PCRE library into the system, or build the PCRE  
library  
statically from the source with nginx by using --with-pcre=  
option.

building stuff from source require installation of development  
(-dev/-devel) packages of its dependencies in ubuntu, rhel, and some  
other distros.

(read: try installing libpcre3-dev)

installing the related ‘dev’ packages was the ticket:

- libpcre3-dev
- libssl-dev
- zlib1g-dev

then acquiring source and static linking can be avoided…

thanks @edho!
