RE: Support for VC++ toolchain (was Re: Absolute paths generatedbylibtool.)

[Duft Markus]

Hi!

If you could tell me how i can bring outlook to do so, i will gladly ;o)
otherwise it would be too much work to hand-quote everything! ;o//

No, i didn't receive your mail, something went wrong there, could you
send it again?? I will be glad to help you ;o)

Yes wgcc would convert the path (even on cygwin this should work!). (i
didn't build wgcc on cygwin a while, but it should work!) Path
conversion and argument conversion is one of the strengths of wgcc ;o)

The configure script for wgcc does search for visual studio (it must be
in PATH). On interix simply globally (system settings) set
INTERIX_COMPILERDIR to C:\vcxx8 and this will do (interix does the rest,
not wgcc there) (for cygwin see below). Wgcc's configure looks for the
compiler and follows a (very simple :o)) rule to find include and lib
directories. Sometimes this doesnt work correctly, but you can edit the
paths in ${prefix}/etc/.wgccrc (see manual -> paths.c, paths.c++,
paths.linker).

The configure check assumes (for now) a full visual studio setup with
platformsdk in the VC dir, not an express edition with extra
platformsdk, so you will have to edit .wgccrc.

On cygwin when i last experimented with it for everything to work i had
to do the following (from a clean environment):

CYGWIN todo:
============

set TMPDIR to /tmp

extend PATH with AT LEAST the following:
<vs-path>/VC/bin:
<vs-path>/Common7/IDE:
<vs-path>/Common7/Tools:
<vs-path>/Common7/Tools/Bin:
<vs-path>/VC/PlatformSDK/Bin:
/cygdrive/c/Windows/system32

============

Hope this helps!

Cheers, Markus

You can't run cl.exe unless you have the right environment variables
set.
According to my install of Visual C++ Express (under C:\vcxx8) these
are:

export VSINSTALLDIR='C:\vcxx8'
export VCINSTALLDIR='C:\vcxx8\VC'
export FrameworkDir='C:\WINDOWS\Microsoft.NET\Framework'
export FrameworkVersion='v2.0.50727'
export FrameworkSDKDir='C:\vcxx8\SDK\v2.0'
export DevEnvDir='C:\vcxx8\Common7\IDE'
export
PATH='C:\vcxx8\Common7\IDE;C:\vcxx8\VC\BIN;C:\vcxx8\Common7\Tools;C:\vcx
x8\SDK\v2.0\bin;C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727;C:\vcxx8\V
C\VCPackages;c:\vcxx8\VC\PlatformSDK'
export INCLUDE='C:\vcxx8\VC\INCLUDE;c:\vcxx8\VC\PlatformSDK\Include;'
export
LIB='C:\vcxx8\VC\LIB;C:\vcxx8\SDK\v2.0\lib;c:\vcxx8\VC\PlatformSDK\Lib;'
export LIBPATH='C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727'

Notice that in the above PATH and INCLUD and LIB, I added MS Platform
SDK's stuff.

The MS Platform SDK adds the following:
export MSSdk='c:\vcxx8\VC\PlatformSDK'
export Bkoffice='c:\vcxx8\VC\PlatformSDK'
export INETSDK='c:\vcxx8\VC\PlatformSDK'
export Mstools='c:\vcxx8\VC\PlatformSDK'

So you're telling me that wgcc would transform a -I/home/build/include
in /IC:\cygwin\home\build\include ?

(by the way, I sent you an email a couple of days ago because I had a
problem with wgcc, did you receive it?)
