It can be used for audio playback, recording, format conversions,
effects processing, mixing, as a LADSPA plugin host and JACK node.  
Version E<gt>= 2.2.X must be installed to use this package.

=head1 INSTALLATION

 perl Makefile.PL

If your perl wasn't built with -Dusethreads or -D_REENTRANT you
will be prompted whether to continue with the install.  It's in
your hands... See L<THREADING NOTE>

 make
 make test
 make install

=head1 THREADING NOTE

The ecasoundc library uses pthreads so will may only work if
your perl was compiled with threading enabled, check with:

Makefile.PL  view on Meta::CPAN

                                s/\\t/    /g' \\
                    )" },
    CONFIGURE       => 
        sub {
            my %cfg;
            use Config;

            unless ($Config{usethreads} eq 'define'
                ||  $Config{ccflags} =~ /\b-D_REENTRANT\b/) 
            {
                prompt_cont(<<EOT, 'y');
Your perl was not built with -Dusethreads or -D_REENTRANT
This may cause problems loading the multithreaded library 
ecasoundc  (hanging on loading).  It has worked fine for some.
You are welcome to try...

Proceed anyway?
EOT
            }
            
            # ecasound 2.4.4 http://www.eca.cx/ecasound-list/2006/12/0007.html
            # old: ecasound < 2.2 (v2.1dev8) mv'd headers and config prgm
            # old: ecasound < 2.0.1 didn't have reentrant C interface
            my $eca_version = `libecasoundc-config --version`;
            if(!defined($eca_version)) {
                warn "Running ecasoundc-config failed: $!\n";
                
                prompt_cont(<<EOT, 'y');
The ecasoundc-config program is used to find the version of the
ecasoundc library.  You need 2.4.5 or higher.

Proceed anyway?
EOT
            } else {
                chomp $eca_version;
                # Compare versions pre v-strings 
                my @ev = split /\./, $eca_version;
                # maj > 2 & rest >= 4.5
                unless($ev[0] >2 || ($ev[0] == 2 && "$ev[1].$ev[2]" >= '4.5')) {
                    prompt_cont(<<EOT, 'n');
Version 2.4.5+ of ecasound is required, you have $eca_version.
                   
Proceed anyway? (bad idea)
EOT
                }
            }
            unless ($ENV{ECASOUND}) {
                print <<EOT;

ECI now uses the "ECASOUND" env var to find the ecasound executable.
