[Pkg-db-devel] Bug#339337: db4.2: Please compile with -D__USE_GNU

[Joerg Wendland]

Package: db4.2
Severity: wishlist

Hi,
Linux supports open(2) flag O_DIRECT. BDB installations can possibly 
benefit from that. Using DB_ENV->set_flags(DB_DIRECT_DB) for example
yields the following error:

  direct I/O is not supported by this platform

But it definitely is. If you compile the package with -D__USE_GNU,
O_DIRECT will be defined in {asm,bits}/fcntl.h and db4.2's
__os_have_direct() of os/os_open.c will return true so that the call to
set_flags as shown above will succeed.

Thank you,
  Jörg
