Re: [cpp-netlib-devel] Bjam woes

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I tried setting those two env variables on my second test.  I  
discovered that there are two more subtle requirements to this approach:

a) your "BOOST_ROOT" directory needs to be writable
b) the code in your "BOOST_ROOT" directory needs to be built

although I suspect b) might not be necessary if the directory is  
writable

I think that having simple ./configure + make to wrap the bjam stuff  
would make things much easier to use, sort of like what is available  
for the main boost distribution..  In particular, it could find where  
you bjam is located, and allow you to set the location of your  
(source) BOOST_ROOT, or alternatively to specify an "installed"  
location of the boost libraries.  If the latter, it would just write a  
new Jamroot file that takes an approach similar to Andreas (specify  
the include locations and libraries we need to link with explicitly).

I realize this would all be redundant after it's (hopefully) included  
in the Boost distro, but in the meantime I think it would make things  
much easier to use. I can take a stab at this, since I've grown quite  
familiar with autotools over the past year..

Regarding the unit test libraries, these seem to be built and included  
in the distro by default on most platforms anyway.  Plus, since cpp- 
netlib is taking a headers-only approach, the unit tests are the only  
thing someone can build.  So it seems like a reasonable requirement  
that you can't "build" cpp-netlib without having the unit test library  
to link with.

Take care,
