[FirstName LastName]

Anybody has any idea why this is happening?  If someone can help me, it would be appreciated.

Hi, I'm cross compiling mono 2.2 for the ARM.  I'm getting linker errors: ../utils/.libs/libmonoutils.a(mono-mmap.o): In function `mono_shared_area_remove':/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:486: undefined reference to `shm_unlink'../utils/.libs/libmonoutils.a(mono-mmap.o): In function `mono_shared_area_for_pid':/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:502: undefined reference to `shm_open'../utils/.libs/libmonoutils.a(mono-mmap.o): In function `mono_shared_area_instances_helper':/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:425: undefined reference to `shm_unlink'../utils/.libs/libmonoutils.a(mono-mmap.o): In function `mono_shared_area':/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:448: undefined reference to `shm_open'/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:460: undefined reference to `shm_unlink'/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:465: undefined reference to `shm_unlink'/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:451: undefined reference to `shm_unlink'/home/ubuntu/Install/cross-arm-mono-2.2/mono/utils/mono-mmap.c:452: undefined reference to `shm_open'collect2: ld returned 1 exit statusmake[3]: *** [pedump] Error 1make[3]: Leaving directory `/home/ubuntu/Install/cross-arm-mono-2.2/mono/metadata' It seems that it expects to find those functions are in librt.so.  However, in my case, they are not implemented. Question=======If I don't have these functions, what can I do to make mono compile. Thanks.
