Re: [Boost-build] absolute include path for bjam with msvc in cygwin

Thanks for your reply. Sorry for my ignorance, I am
fairly new to Windows and Cygwin ;) 

I noticed that if I use the NT-version of bjam (the
one ending up in tools/jam/bin.ntx86 after compiling
with build.bat), then the include paths are working
correctly, even though they appear as Cygwin-paths in
the output of "bjam -d2". Are they being translated to
Windows-paths before sent to msvc?

But uhhhh, what version of bjam (NT or Cygwin) should
I use to compile my own projects? In my case, I use
Cygwin because I want to be able to use Linux tools
for development, but I want to create native Windows
apps (i.e. I want my executables and libraries to be
the same as if I would compile them in Visual Studio).
Which one should I choose then,
tools/jam/bin.ntx86/bjam compiled with build.bat (vc9)
or tools/jam/bin.cygwinx86/bjam compiled with build.sh
(gcc)?

Cheers,
Andrej
