I imagine making sure Build.bat sets SHELL=cmd.exe AND appropriate %PATH% is better than annoying users :)

Thanks for the link, this will certainly help. As this goes into Module::Build territory, and I'm not keen on learning on how to make Module::Build add arbitrary commands to the created Build (well, Build.bat) script, I won't change my patch. Somebody with knowledge of Module::Build is welcome to take my patch and make things work right out of the box.

The appropriate commands would likely be (ignoring systems where we have command.com):

set SHELL=cmd.exe
[download]

... and, after appropriate munging in Perl to remove all offending directories in $ENV{PATH}:

set PATH=$cleaned_path
[download]

$cleaned_path would likely be something like:

my $cleaned_path = join ";",
                   grep { ! -f "$_\\sh.exe" && ! -f "$_\\cc1.exe" }
                   split /;/, $ENV{PATH}
                   ;

This works for me as in it starts building and doesn't die immediately with CreateProcess(NULL, better than renaming sh.exe and make.exe :)

sub build_wxwidgets {
    my $self = shift;
    my $old_dir = Cwd::cwd();

    my $uni = $self->awx_unicode ? 'UNICODE=1'   : 'UNICODE=0';
    my $mslu = $self->awx_mslu   ? 'MSLU=1'      : 'MSLU=0';
    my $dbg = $self->awx_debug   ? 'BUILD=debug' : 'BUILD=release';
    my $opt = join ' ', $uni, $mslu, $dbg, 'SHARED=1', 'SHELL=cmd.exe'
+;

This was a flop , dies with CreateProcess(NULL, probably all that reboot talk ... nonsense :)

    my( $self ) = shift;

    if( $self->notes( 'build_wx' ) ) {
        $ENV{WXWIN} = $ENV{WXDIR} = File::Spec->rel2abs
          ( $self->notes( 'build_data' )->{data}{directory} );
        $ENV{SHELL} = 'cmd.exe' if $Config::Config{sh}=~/cmd/i;
        
        my $mingw_gcc = My::Build::Base->awx_path_search( '*-gcc-*.exe
+' ); # i686-w64-mingw32-gcc-4.6.3.exe
        my $basename = File::Basename::basename($mingw_gcc, '.exe' );
        $basename = "libexec/gcc/$1/$2" if $basename =~ m{^(.+?)-gcc-(
+.+)}is;
        my $new_path = File::Spec->rel2abs(
            File::Spec->catfile(
                File::Basename::dirname($mingw_gcc) ,
                File::Spec->updir, 
                $basename
            )
        );
#~         die "SHELL=$ENV{SHELL}\n$mingw_gcc\n$basename\n$new_path";
        $ENV{PATH}.=';'.$new_path;
## didnt work

    }

That approach looks sound to me.

Its better than nothing, and better late than never,

But we can do better than a copout from so many years ago

I imagine this is relevant portion but I havent built a wxWidgets in years

If you could check your logs please

It is unclear what it is that you're asking for here. What should I be checking for in the logs?
