[MACTCL] Compiling extensions

[Steve C. <ste...@mq...>]

I'm finding my feet with porting mac extensions. After getting the XML 
project file for QuicktimeTcl from Daniel I've managed to put together a 
project for the sample extension with only a few obvious changes. However to 
get the project to link I had to add Tcl8.3.shlb and Tk8.3.shlb in addition 
to the two Stib.lib libraries.  

The extension now links and I can load it into tcl and the commands are there 
but it crashes when I try: 

sha1 -string foobar

so obviously something is amis.  

 - should the project include the two shlb files? 
 - does someone have a port of the sample extension to CW6 and Daniel's 
build? 
 
 my goal is not so much to get the sample extension going but to be able to 
port my own code so I'd like to understand the requirements of the build 
system and why this is failing. 

Any help appreciated.
