--with-sysroot usage

--with-sysroot usage

[Asfand Yar Qazi]

Hi,

Sorry if this is a bad question, but its driving me crazy.

I'm trying to get a cross-compiler for mingw32 hosted on Linux.

I downloaded the win32 libs and headers and stuff and placed them in 
the directory /opt/mingw32-cross/i386-mingw32

Binutils 'i386-mingw32-as' etc go in /opt/mingw32-cross/bin, man pages 
in /opt/mingw32-cross/man (prefix to all packages is /opt/mingw32-cross)

Libraries and stuff go in /opt/mingw32-cross/i386-mingw32/lib and 
/opt/mingw32-cross/i386-mingw32/include and 
/opt/mingw32-cross/i386-mingw32/bin, etc.

I'm fine with the rest of the stuff, but here's the question:

To the GCC configure script, which of the following do I pass:
* --with-sysroot=/opt/mingw32-cross/i386-mingw32
* --with-sysroot=/opt/mingw32-cross
* something completely different

I'm not sure about this.  I went with number 1 
(--with-sysroot=/opt/mingw32-cross/i386-mingw32) and discovered I had 
to (cd /opt/mingw32-cross/i386-mingw32 ; mkdir usr; cd usr; ln -s 
../lib .; ln -s ../include .)

There has to be a better (less 'kludgey') way to get this setup going. 
  It seems to work fine (apart from cross-compiled C++ programs that 
use the Boost library that mysteriously crash on startup) but I want 
to get the --with-sysroot flag figured out.

Before you tell me, the install docs are a bit vague, and I haven't 
found any answers on the web or on the archives of this mailing list, 
so I'm asking here.

Thanks,
     Asfand Yar
