Description Saul Wold 2017-02-14 17:19:40 UTC 
Using the following settings, pseudo fails to build

MACHINE="intel-corei7-64"
DEFAULTTUNE = "corei7-64-x32"

t.o: In function `pseudo_client_op':

Comment 1 Seebs 2017-02-16 16:18:14 UTC 
So this is weird because this is exactly the failure we previously coded around, and the #if condition on the 2.2.5 versioning is explicitly checking for what I thought was the define used for x32.

See ports/linux/portdefs.h, it's the test for __amd64__ and __ILP32__. If x32 isn't ILP32, I am very confused.
Comment 2 Joshua Lock 2017-02-16 16:29:16 UTC 
The x32 fix wasn't in pseudo 1.8.1, it *is* in pseudo 1.8.2 but that only landed in OE-Core/poky master in the last 24hrs.

I just verified that I can build pseudo 1.8.2 with Saul's settings.
