Re: Postgres Windows build system doesn't work with python installedin Program Files - Mailing list pgsql-hackers

Hi Michael,

I performed a quick test for the path "msvc-build-init-v2.patch" using
below cases:

1. perl build.pl
2. perl build.pl debug psql
3. perl build.pl RELEASE psql
4. perl build.pl deBUG psql
5. perl build.pl psql
The above cases (case-insensitive) are all working great without any
warning for latest master branch.

When build with more than 3 parameters, yes, I got below expected
message as well.

c:\Users\david\Downloads\postgres\src\tools\msvc>perl build.pl DEbug
psql pg_baseback
Usage: build.pl [ [ <configuration> ] <component> ]
Options are case-insensitive.
configuration: Release | Debug. This sets the configuration
to build. Default is Release.
component: name of component to build. An empty value means
to build all components.


However, if I ask for help in a typical Windows' way, i.e, "perl
build.pl -help" or "perl build.pl /?", I got some messages like below,

c:\Users\david\Downloads\postgres\src\tools\msvc>perl build.pl -help

For switch syntax, type "MSBuild -help"

It would be a bonus if the build.pl can support the "help" in Windows' way.


Thanks,

David
