Do you mean:
I don't know RosBE, but it semms to be more comparable with MSYS(+GnuWin32)
My goal is to build win32 applications from a Unix system, not from
windows. This has several advantages over native win32 compilation,
because it enables great simplifications:
1) no need to port the development tools
If you're building on a Unix system, you already have tar, bzip2,
lex, yacc, a Perl interpreter, etc.
All those build tools and interpreters don't need to be ported, you
can just use them. MSYS and Cygwin, however, need to port them to
2) no need to compile whole source packages
When you compile a library, you don't need to build the command
line tools, because they won't run in Unix anyway.
Say, for example, that you want to cross compile libcurl. Then
you don't need to build the "curl.exe". Just build the "libcurl.a".
3) no need to compile shared libraries (DLL files)
When you port a big application to win32, you usually want to
present one package for the windows users, that includes everything
they need to run it. The simplest way to achieve that goal is to
statically link all needed libraries. So you just need e.g.
"libcurl.a". You don't need to build "libcurl.dll" and "libcurl.dll.a".
Even if you need to provide some libraries as DLL files (e.g. glib, GTK),
you should put them into your "Programs" directory, separate from any
If you don't, i.e. you install them system-wide to "Windows/System",
you'd have to take care of different DLL versions, which isn't not
possible. Windows doesn't have a suitable package system, so you're
going to have a lot of trouble, the so-called "DLL hell".
I usually agree that the best way to port an application to platform X
is to natively build it on platform X. However, this is only true for:
X != embedded (incapability of the hardware), and
X != win32 (incapability of the OS).
For those X you need a X-compiler (cross compiler).

This question is answered in my article:

No, but it may help them. I don't belong to Debian-win32, and in my
opinion, it's nearly dead. For the above reasons, I also think that's
the wrong way if you just want to port an application to win32.
The main problem of projects like Debian-win32, MSYS and Cygwin is
that they try to solve a big problem with a small community.
The main idea behind my script is to simplify the problem and provide
a solution that can be fully understood and maintained by a single

Please repost this question to the debian-win32 list.
