Help to speedup compilation

[andrea-110]

Hi,

I usually build QuantLib from svn and go through the usual autogen.sh, configure etc...

I've noticed that the whole compilation takes a very long time (on my 5 year old laptop).

"Examples" is the slowest part: a minimal change triggers the whole recompilation of examples
(the library is only rebuilt where/when needed)

I was wondering if there is any easy way to switch it off.
the flag --enable-examples in configure is only used to install them or not.

Andrea,

I use VC++ instead of Linux/Unix but I would try opening
QuantLib\configure.ac and deleting some of the last lines (related to
Examples and testsuite).
Just take care about testsuite line because it ends with "])" which must
be in the final of the directory list.

Regards,

No, you'd also have to modify Makefile.am.

If you want to build only the library, just run make from inside the ql
directory.
