Hi again,
I searched a little bit more, and this occurs only if the drive where I run the ‘cl /?’ Is a ‘Subst Drive’
Therefor, I’ve changed this to a real Drive, and the error does no more occurs. It is a bug in windows with ‘Subst drive’ probably
So, you can either close the bug, or change the ‘cl /?’ by a ‘cl /help’ (which is also an official cl option)
Regards
Robert

Subject: RE: BUG #16825: When building on Windows, cl /? retrun 'x64' not AMD64 and the build does not create x64 environment
Hi,
Yes, I see
Don’t know why when I’m doing the cl /? In the Visual Studio path of the x64 Native Command Prompt, the response contains all the help (including the /flavor: ….)
Once I change to the postgresql\src\tools\msvc for to build, the ‘cl /?’ Only gives back 2 lines and say invalid option.
But I also remarked that if you pass ‘cl -?’, it works correctly in both case. Do you think it is possible to change the ‘cl /?’ by ‘cl -?’ ?
Thanks for your help
Regards
Robert

in src\tools\msvc\Solution.pm the following test is not sufficient
$self->{platform} =
($output =~ /^\/favor:<.+AMD64/m) ? 'x64' : 'Win32';
because the cl /? returns:
Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29336 for x64
Copyright (C) Microsoft Corporation. All rights reserved.
I see no bug here, that expression is looking for the line: "/favor:<blend|AMD64|INTEL64|ATOM> select processor to optimize for, one of:", which is one of the first printed options.
To make sure this is working in your environment, you should see "Detected hardware platform: x64" when building.
