[Buildroot] Build error for nptl with no-mmu (arm7tdmi)

[Buildroot] Build error for nptl with no-mmu (arm7tdmi)

[Axel Lin]

hi list,

In my config, I have
# ARCH_HAS_MMU is not set.

I got below build error (I got the same error on both buildroot-2013.05 and current git tree):

Any idea how to fix this?

hi,

Seems I hit this bug:
[Bug 6224] New: Cannot enable threads on arm7tdmi (MMU-less) arch
http://lists.uclibc.org/pipermail/uclibc-cvs/2013-May/031094.html

Now I switch to compile with

# ARCH_HAS_MMU is not set
LINUXTHREADS_OLD=y
# LINUXTHREADS_NEW is not set
# UCLIBC_HAS_THREADS_NATIVE is not set
UCLIBC_HAS_THREADS=y


But I got another compile error: (compile against current git tree)
