Hello, I am trying to compile 2.6.26.6-rt11 for an ARM-based board using AT91RM9200, but get the following error message when I compile: LD .tmp_vmlinux1 kernel/built-in.o(.text+0xdf08): In function `$a': : undefined reference to `wrong_size_cmpxchg' kernel/built-in.o(.text+0xe05c): In function `$a': : undefined reference to `wrong_size_cmpxchg' kernel/built-in.o(.text+0xe32c): In function `$a': : undefined reference to `wrong_size_cmpxchg' make: *** [.tmp_vmlinux1] Error 1 I get the message both using my custom board and the EK-board from Atmel. The cross-compiler is version 3.4.1. Any ideas of what has gone wrong?
