Subject Re: Building on Windows
Date Tue, 09 Feb 2016 17:40:10 GMT
The icu module has a complicated build with scripts generating makefiles...

I am not sure what approach to even take debugging this, but some ideas
might be:
* make a copy of a main/icu[/wntmsci12.pro] directory that builds and a
copy of one that doesn't, then diff the files to see what's different
* compare build logs with it working and not working, to see what steps
differ (eg. build order of some files might be different)
* try and follow the makefile to understand the problem analytically; my
first try didn't get me far
* give up completely, and just hack it. Make a loop in build.pl that just
keeps cleaning and rebuilding the module. If it builds 50% of the time,
with 10 retries only 1 in 1024 builds will fail, with 20 retries only 1 in
2^20 will fail, etc. Something like this might already have been tried in
the past, as build.pl contains the following code which is only run on
Windows:

sub give_second_chance {
    my $pid = shift;
    # A malicious hack for mysterious windows problems - try 2 times
    # to run dmake in the same directory if errors occurs
    my $child_nick = $processes_hash{$pid};
    $running_children{$folders_hashes{$child_nick}}--;
    delete $processes_hash{$pid};
    start_child($child_nick, $folders_hashes{$child_nick});
};
