Is Gentoo3 or Gentoo4 selecting the wrong mutex implementation?

I really don't know what implementation it would've chosen :) As I said, this was a default build using the ebuild from portage in gentoo, now that I know that its working with that it is time to start playing with some of the variables involved.

I do, however, agree that it is curious that it default to this setting, as for why you'll have to ask the gentoo maintainer.

Understood. I just wanted to point out alternatives and perhaps

with some context for making choices. There's a lot of hysteria

around.

Ultimately you can build BDB however you want and -- if/when BDB breaks --

blame Sunacle (there's a *lot* of "Berkeley DB Haters" around everywhere).

Btw the use of x86/gcc-assembly seem to be platform-specific,
       $(use arm && echo --with-mutex=ARM/gcc-assembly) \
       $(use amd64 && echo --with-mutex=x86/gcc-assembly) \

Removing it from the ebuild now. Removing it, configure ..
checking for mutexes... POSIX/pthreads/library/x86_64/gcc-assembly
checking pthread.h usability... yes
checking pthread.h presence... yes
checking for pthread.h... yes
checking for main in -lpthread... yes

and the resulting partial build log from compile is attached.

I'm starting a new SKS build from dump now, so will be interesting to see if anything else happen

PS! indeed, not blaming BDB for anything per se, but I am curious as to the effect (if any) of different configure options.
