Red Hat Bugzilla – Bug 62718
compile flags not passed down to db3 build dir
Last modified: 2007-04-18 12:41:41 EDT
Description of Problem:
mysql is built with these extra flags: -O2 -fsigned-char -D_GNU_SOURCE
But only -D_GNU_SOURCE is used is used while compiling db3 in the bdb directory.
Besides the missing optimization, linking together objects with different
notions of eg. off_t scares me.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. rpmbuild --rebuild mysql-3.23.49-2.src.rpm
The regression tests on bdb succeeds with the current set of flags, and it seems
to work fine with manual tests, too. The tests for bdb fail when I trick it into
using these flags, so I won't do that for now. (adding CPPFLAGS do the trick)
Would you mind telling me which bdb regression tests fail? I'm tracking a
strange failure (bdb-deadlock aborts the server) on PPC.

Fix gcc-2.96 miscompilation of db3
Ah, I remember now. This is most probably a miscompilation by gcc-2.96-109, a
patch went into gcc-3.0.3. Recompile gcc-2.96-109 with the attached patch and
then recompile mysql with it.
Hmm, I wonder why Jakub didn't apply the patch to gcc-2.96, I notified him back
then. Cause even if mysql is currently not affected because it builds db3 with
optimization, the standalone db3 package is still affected.
Bugs/patches against gcc need to be filed against gcc.... building mysql now to
find out which test failed, I overwrite those logfiles ('foo' isn't exactly
intended for long time storage :).

Aborting. To continue, re-run with '--force'.
Could you please retry with gcc-2.96-110 yourself? It works for me now with the appended
patch (the lazy configure-only patch :-) ) to mysql.

Correctly handle CFLAGS during configure in mysql/bdb
