The syntax of the command is incorrect

[tarek-kandil]

It says genhtml.perl: ERROR: cannot create directory gcov/html/!

[Indigo6]

the same error

[Indigo6]

It says genhtml.perl: ERROR: cannot create directory gcov/html/!

I fixed it. It comes from

sub create_sub_dir($)
{
    my ($dir) = "gcov\\html";         //was "gcov/html"
    printf("%s\n",$dir);
    system("mkdir",$dir);
}

and Windows cmd does not support 'mkdir gcov/html'
