Bug #51062 [Bgs]: DBA DB4 build uses mismatched headers & libraries
Edit report at http://bugs.php.net/bug.php?id=51062&edit=1 ID: 51062 Updated by: s...@php.net Reported by: seanius at debian dot org Summary: DBA DB4 build uses mismatched headers & libraries Status: Bogus Type: Bug Package: DBM/DBA related Operating System: Debian PHP Version: 5.3.1 Assigned To: sixd New Comment: The change is in: http://svn.php.net/viewvc?view=revision&revision=295844 Previous Comments: [2010-03-05 06:39:12] s...@php.net I added DB 4.7 & DB 4.8 to the autodetect list in config.m4 for PHP 5.2.14-dev, PHP 5.3.3-dev and PHP 6. This changes the default behavior and may help many cases. It certainly allowed DBA DB4 to work when I had 4.7 headers and 4.7 & 4.6 libraries, and built using "--with-db4". Without the change I saw the corrupted output you reported. Config.m4 still doesn't check the library version matches the header version. [2010-02-19 08:57:34] seanius at debian dot org actually it's fairly common (at least on debian-derived systems, couldn't speak for others) to have multiple versions of libdb installed. The problem is that the code that does the testing of headers will match against a generic "db.h" and then will happily link against any other version of libdb that it finds (and it doesn't seem to be searching includes/libs in the same order). i'd argue that the configure detection ought to be a bit more thorough in this regard but won't press the point.

If you mess your system with multiple libs and headers, that's your problem. [2010-02-17 22:40:04] seanius at debian dot org some more investigation reveals that the problem was caused by having db4.8 headers alongside db4.6 and db4.8 runtime libraries (i.e. having installed libdb4.6, libdb4.8, and libdv-dev (which is 4.8 in latest debian/ubuntu)). the build scripts find the the headers from the db4.8 package, and the 4.6 libraries since there is no code for testing for versions > 4.6. strangely enough it's able to build/link. having the libdb4.6 headers installed instead of the 4.8 headers removes the problem and the tests pass, but i would argue that this is still a bug. namely: * php doesn't support building against db4.8 (i could report a seperate bug about this if it's better) * php wrongly builds against headers for one version of libdb and links against another.
