[aspectc-user] Building from source

[Olaf Spinczyk]

Hi Eric,

there are two ways of compiling Puma and AspectC++:

1. compile from the "woven sources"

    => use "make compile" to compile Puma, no ag++ is needed

2. compile from the  woven sources

    => use "make" to compile Puma, ag++ is used to weave the code

The problems with linking ac++ are due to the libxml2, which references 
libpthread. If you try to link libpthread statically, you get the 
warnings below. Therefore, we configure the libxml2 on our own as 
described in AspectC++/README.

Alternatively, you can link libxml2 dynamically. However, therefore you 
would have to modify the AspectC++ Makefile. You could also use Reinhard 
Tartlers Debian packages (see downloads page).

Regards,

Olaf
