sb-sprof doesn't work on Windows.

[[e-mail]]

When I attempt to use the statistical profiler on Windows, I get the error:

; Evaluation aborted on #<UNDEFINED-FUNCTION UNIX-SETITIMER {1002B4DC33}>.

I'm running "SBCL 1.1.4.0.mswin.1288-90ab477".

If I download the 1.1.12 Windows executable and attempt to profile, I get a different error:

The variable SB-UNIX:SIGPROF is unbound.

The manual suggests that statistical profiling works on Windows. Is that incorrect, or is there some problem in the way I'm trying to use it?

The manual doesn't suggest that. sb-sprof was never ported to windows.

From the manual:

>> This module is known not to work consistently on the Alpha platform [...] However, it should work on other platforms

I took "other platforms" to include Windows. If that's not the case, perhaps the manual could be updated to state more explicitly where the module is supported.

Thanks.

Minor clarification for users who might not be aware of the SBCL/win32 forking situation:

sb-prof was ported to windows, but that patch hasn't been merged into SBCL proper yet.

Shouldn't be hard to do, patches encouraged. You might want to start by taking a look at https://github.com/akovalenko/sbcl-win32-threads/commit/c90e4369ed6bc8c6fa6902078c17fc68973e484a as well as any followup- changes to the same code.
