Note that the error has been reported to happen on FreeBSD - so I doubt

Anyway, our include/standard-headers/linux/types.h is also empty ... so
could you try whether it compiles if you simply remove this #include
line, Rebecca?

Sorry for the delay, I'm just getting back to this. Removing the include
causes it to fail later on, with:

/home/bcran/workspace/qemu/hw/rdma/vmw/pvrdma_cmd.c:60:17: warning:
implicit declaration of function 'mremap' is invalid in C99
     host_virt = mremap(curr_page, 0, length, MREMAP_MAYMOVE);
OK, thanks for checking. According to


that syscall should also be available on FreeBSD. So could you please do
one more test and see whether it works when you add the following line
somewhere at the beginning of the file:

   #include <sys/mman.h>

It took some time, but I finally have a FreeBSD VM with RDMA enabled.

My findings:
- The RDMA libraries are there, so the flag  "RDMA"=yes is set correctly.
- include of <linux/types.h> is not needed, I will remove it.
- In FreeBSD mremap is not implemented in all configurations, it depends
  on some SANITIZER_LINUX flag (Linux emulation?), I think;
  so pvrdma cannot be compiled.  I think we should have a different QEMU configuration   flag --enable-pvrdma that will specifically check it is not a "bsd" platform.
  I'll send a patch for that too.
