| Subject: | Compat Makefile.PL bombs when Build.PL tries to abort installation |
The CPAN testing service uses the convention of not sending FAIL reports
when a setup script (Build.PL or Makefile.PL) exits successfully, but
does not create its file (Build or Makefile). This prevents us from
being flooded with FAIL reports for systems which do not have important
prerequisites installed.
Following this standard, I put a check in my Build.PL to see if perl is
not compiled for threads. It does an exit(0) if it isn't. All goes well
if the Build.PL is run, but if I define a passthrough Makefile.PL, the
Makefile.PL tries to load in _build/prereqs, fails, and errors out,
which leads to the bug report I was trying to avoid in the first place.
An example:
Output from '/usr/local/perl-5.6.2/bin/perl Makefile.PL':
# running Build.PL
/usr/local/perl-5.6.2/bin/perl Build.PL
Unable to install. The Xine module requires multithread support.
Can't read _build/prereqs: Datei oder Verzeichnis nicht gefunden at
/usr/local/perl-5.6.2/lib/site_perl/5.6.2/Module/Build/Compat.pm line 244.
If there is a way to define an environment check to work around this,
I'd love to hear about it.
See http://www.nntp.perl.org/group/perl.cpan.testers/2007/12/msg905933.html
for the example failure report.
