I compiled a new rootfs for my SAM9-L9260-Board from Olimex.
I used the buildroot-2011.08, with uClibc-0.9.32.

The compiling worked just fine, but when i try to compile my own program on the
Target it failes.

Here the situation which lead to the bug:
My compile command:

g++ -g /TPSController.cpp -llua -ldl -lpthread -o /TPSController

My compile output:

/usr/lib/gcc/arm-unknown-linux-uclibcgnueabi/4.3.6/../../../libc.a(sigprocmask.os):
In function `sigprocmask':
sigprocmask.c:(.text+0x0): multiple definition of `sigprocmask'

collect2: ld returned 1 exit status


I've got the same fault even if i try the different thread implementation that
uClibc has. I thought that the NPTL should be fixed in the uClibc-0.9.32
