Issues faced while trying to install nginx from source on mac osx lion.
After downloading the latest stable nginx source files I started
to build nginx as instructed on the site .
./configure --conf-path=/etc/nginx --with-http_ssl_module
The first configuration option specifies the location of the nginx.conf file and the second one
ensures that nginx is build with https support for web servers.
There is a wide choice of configuration options that can be found here .
The configure stage went through well , however when I tried to do a "make" ,
I ended up with the following error :

"
A bit of search led me to this.
Reason as mentioned in the solution :
"The Mac OS X have /usr/lib/libpcre.0.dylib in base system and strange system search paths, so installing PCRE into /usr/local/ won't work - the pcre.h will be used from /usr/local/include, but libpcre.0.dylib will be used from /usr/lib (not /usr/local/lib)."
So I uninstalled/removed the existing pcre ( I deleted the pcre libs and header files in the /usr/local/include and usr/local/lib folders) and installed pcre using macports .
Reinstalling leads to the pcre files getting installed in /opt/local folders.
Run the configuration step again , otherwise your old Makefile will still point to
the /usr/local for pcre .
After a successful ./configure , do make and then make install .
And you can find your nginx executable in /usr/local/nginx/sbin ( which is the default
location for you nginx executable unless you configure it differently ).
In my case as I configured my conf path differently , I also had the nginx.conf inside
/etc/nginx/ folder .
You can of course start nginx pointing it to a different configuration file ( with the -c option ).
In the next posts I will try to document my experiment running nginx , in particular how caching
works.
