linux/smp_lock.h not found

business_kid · 03-07-2021, 08:32 AM

I'm on the 64bit Current iso of 2021-02-11 with kernel-5.10.15

VirtualBox is not able to building it's modules.

Code:

In file included from /tmp/vbox.0/linux/SUPDrv-linux.c:33:
/tmp/vbox.0/r0drv/linux/the-linux-kernel.h:141:11: fatal error: linux/smp_lock.h: No such file or directory
  141 | # include <linux/smp_lock.h>

I haven't got that file. It wasn't in the earlier versions (VB-6.1.6? & kernel-5.4.68 supplied with Current 2020-09-28) so I imagine it's a new requirement.

I gather this was an old problem cured before 4.x kernels. Searching is throwing up 'hit and miss' stuff. Is there a workaround or fix?

Hello,

According to this bug report, this is fixed in VB 6.1.16.

Thanks, phenixia2003, it seems to be fixed ok 6.1.18 gave no trouble. smp_lock.h seems to be one of these "quantum" headers known only to software devs that is often called, but never chosen because it doesn't exist at the point in time
