smoketest.php fails on Solaris

[Dagobert Michelsen]

The test smoketest.php from xapian-bindings dumps core when compiling against PHP 5.3.15:

That looks like it's crashing in C++ standard library initialisation.

Is this only for the smoketest, or does any PHP script using xapian fail?

Did this work with previous versions with this compiler?

[Dagobert Michelsen]

In fact I don't know. I enabled the PHP binding just recently and don't use it myself but provide it as a courtesy to users of my produced package. Is there anything I could test easily manually?

[Olly Betts]

Aside: If you're building binary packages to distribute, you probably don't want to build the PHP bindings, as built binaries probably aren't currently legally distributable due to GPL/PHP licence incompatibility. Source packages or build scripts (like BSD ports or Gentoo ebuilds) are probably OK.

It looks to me like this toolchain isn't coping with a C program (i.e. PHP's php5 command line interpreter) dynamically loading a C++ plugin (i.e. the Xapian PHP bindings xapian.so), though if the other bindings work, it clearly isn't quite as simple as that.

I would suggest you try installing the bindings (make install), and then run the smoketest using the installed bindings - this will probably work:

php5 -d safe_mode=off -d enable_dl=on smoketest.php

If that doesn't work/help, you could try telling PHP to load the module at startup by adding this line to the [PHP] section of the appropriate php.ini:

extension=xapian.so

And then just use:

php5 smoketest.php

[Olly Betts]

Did you get a chance to try what I suggested in comment:3?

[Dagobert Michelsen]

Sorry, I got distracted, I'll try the update to 1.3.1 and then follow up on this issue.

[Olly Betts]

It's possible this is fixed by r18247.

[Olly Betts]

There have been some other fixes since my last comment, so trying 1.3.2 would be useful.

[Olly Betts]

I tested 1.2.20 on the opencsw unstable10s machine and the test passes - I assume this is the same bug as #652, and so was actually fixed in 1.2.19.

1.2.20 needed a couple of tweaks to build with Sun's compiler, will commit those to master and backport for 1.2.21.

[Dagobert Michelsen]

Hi Olly,

thanks for having an eye on fixing this issue. I'll give it a try next time I update our packages.

Thanks and best regards -- Dago
