Baruch, Max,
We have recently update glib to version 2.40, and this is causing
issues on Xtensa:
http://autobuild.buildroot.org/results/a1a/a1a1f97a2c54ba4f7f7e44cc094a55bd23ca0aa0/build-end.log
CC gspawn.lo
gthread-posix.c: In function 'g_cond_impl_new':
gthread-posix.c:648:2: error: #error Cannot support GCond on your platform.
#error Cannot support GCond on your platform.
^
gthread-posix.c: In function 'g_cond_wait_until':
gthread-posix.c:896:2: error: #error Cannot support GCond on your platform.
#error Cannot support GCond on your platform.
^
gthread-posix.c:859:19: warning: unused variable 'ts' [-Wunused-variable]
struct timespec ts;
^
Could you have a look and see what can be done to fix this problem?
Thanks!
Thomas

It requires pthread_cond_timedwait_relative_np (not available on uclibc)
or pthread_condattr_setclock (only available with NPTL). Looks like we
need NPTL to support this glib version.

Well, libglib builds fine on ARM/uClibc.

Argh. There's no NPTL support for:
- ARC (but I believe it's coming)
- AVR32 (but we're deprecating this architecture, so we don't care)
- Blackfin (and I don't think there's much hope to have NPTL one day,
but glib is anyway disabled on !MMU platforms, so we don't care)
- Xtensa (don't know)
- i386 (because NPTL requires at least i486)
Should we patch glib to make the support of the GCond stuff optional,
and hope not too many programs will use it? Or simply add the NPTL
dependency to glib, but that would mean a huge number of packages
suddenly become unavailable for some architectures.
Best regards,
Thomas

There's a patch in glib mainline that implements GMutex natively on linux.
It applies cleanly to glib-2.40 and with it xtensa builds successfully.
I can post a buildroot patch with it.

Thanks.

We're planning to complete NPTL implementation this year.
