Expectations for Windows Programmers

Expectations for Windows Programmers

[horizonx]

I am not a C programmer, but it sounds like I should be able to use gcc and
dlltool to build a Wintel DLL.

It is unclear from reading the Cygwin User's Guide if I will actually be
able to link this DLL with other programming languages outside the Cygwin
environment.

Is the Cygwin, gcc route a more straightforward way to compile a Linux,
POSIX compliant library than using a Wintel compliler?

Thanks,

Terry

It is theoretically possible, though you will have to thoroughly 
understand the toolchain and DLL mechanisms.

You can build a cygwin-independent object file by compiling with 
-mno-cygwin. You may need the "mingw" package to get windows headers for 
  this.

Once you do this, you should be able to build a regular windows DLL, and 
even generate .LIB export stubs for this DLL. However, I must confess 
that I don't have references and man pages handy. Much of this 
"knowledge" comes from when I ported the toolchain to an experimental 
platform that is now defunct.

Thanks Joshua and Shankar for the info.

Considering the wealth of source code available in the UNIX/LINUX community,
I felt it was newsworthy that a basic tool set is available for possibly
automating the conversion of open source libraries.

Within the OS survival game, this would amount to deep incursion into "enemy
territory".

Can you give any ballpark figure of the amount time it would take to convert
a "typical" library right now?

Thanks,

Terry

Sounds like you may be more interested in mingw:
