linking a selfmade library

[Lars Uffmann]

My current development environment:
 - WinXP SP2 english
 - Eclipse Europa + CDT using
    - gnu-toolchain implemented via cygwin
    - Widestudio Native Application Builder plugin for eclipse

All of these are working fine together, so I can "click together" my 
windows, and add code via event procedures.

Now from what I understand, GUI applications that integrate with the 
operating system are somewhat different as to their main()-function: Not 
sure if it exists at all, but at least the eclipse/NAB environment 
doesn't let me peek at it, if it's there.

I used to go about including a selfmade c++ library (lib.c & lib.h) by 
compiling it to a binary, and then linking it. But that was under Linux, 
with my own makefiles - and I have forgotten a lot.

Let's say I have some general functions that I want to call from several 
of my GUI classes (e.g. from the mainwindow event procedures) - so I 
create a new general.cpp file, declare the function headers in 
general.h, include the general.h file whereever I need it and ... well - 
and what? How would I go about telling the compiler to precompile the 
functions in general.cpp that require(!) the GUI libraries, and then 
link that general(.o?)-library into the application executable?

My main problem is that I am using the CDT Makefile Builder, so if 
anyone is familiar with eclipse, if you know any options that will allow 
this one to continue working, that would be awesome.

Otherwise - for a start - the command line approach for g++ would help 
me understand / remember.

Thanks a lot!
