Build fails on OpenBSD (generic_files/profiler.c)

[Oliver Krüger]

Hejhej,

Building flint-3.5.0 and flint-3.4.0 (at least) fails on OpenBSD (7.8, amd64)
when compiling generic_files/profiler.c, with error

/opt/flint-3.5.0/src/generic_files/profiler.c:193:24: error: member
reference base type 'u_int64_t' (aka 'unsigned long long') is not a structure or union
  193 |     virt = kp.p_vmspace.vm_map.size;
      |            ~~~~~~~~~~~~^~~~~~~
/opt/flint-3.5.0/src/generic_files/profiler.c:194:23: error: member
reference base type 'u_int64_t' (aka 'unsigned long long') is not a structure or union
  194 |     rss = kp.p_vmspace.vm_rssize * getpagesize();
      |           ~~~~~~~~~~~~^~~~~~~~~~
2 errors generated.

This is not how kinfo_proc works op OpenBSD (defined in sys/sysctl.h). The
following patch seems to work:

193,194c193,194
<     virt = kp.p_vmspace.vm_map.size;
<     rss = kp.p_vmspace.vm_rssize * getpagesize();
---
>     virt = kp.p_vm_map_size;
>     rss = kp.p_vm_rssize * getpagesize();

ChatJippity does not seem to know how to BSD.

M.v.h.,
Oliver

Hi Oliver,

Thanks for raising this issue.  I'll fix it in the coming hours.

Best,
