Hi everyone,
here are two patches I’ve been rebasing with each new upload
of alsa-lib to Debian to make things work for my x32 desktop.
The small one fixes it misdetecting x32 as amd64, which leads
to an immediate segfault.
The other one fixes issues related to printing time_t values
on platforms where time_t is 64 bit wide and long 32 bit wide
(various BSDs and all new 32-bit and *64ilp32 Linux platforms).
The Debian packager of alsa-lib hasn’t found it necessary to
forward them upstream, so I’m doing it with this. I hope they
can be included in the next releases. The patches were last
updated for 1.1.8 although I need to update them to 1.1.9 which
was recently introduced to Debian… usually they apply still.
Thanks in advance,
//mirabilos
