Xiaokun Zhu,

I have been working on a DLL rule/actions for NT recently and have something that sort of works but needs refinement.

One of my objectives is to be able to specify a target which may be selected to be a static library, a shared object or a DLL using one rule, IYSWIM.

i.e

WilfsLibrary wibble : wibble1.c wibble2.c ;

which would generate libwibble.a, libwibble.so, wibble.lib or wibble.dll (etc) dependent on variable settings and platform.

So far I have a rule Dll and supporting actions which does some of what I need - I include this below along with an example invocation from a Jamfile. It is just based on the Main and MainFromObjects stuff in Jambase. I'm sorry but I can't guarantee that it is working coz it's a few weeks now since I was working on it and I had to drop it rather quickly.

Hope this helps. If you come up with a good generic rule I'd be interested in seeing it. If I do, I will post it :-)

Whatever, I will try and post an updated, commented version as it gets a bit better. I think the comments are important because I find it *really hard* to write these rules.

Cheers, Wilf Coles DAIS COnsultant

================================================================== Jamrules stuff:

========================================================================== example invocation in Jamfile:
