Summary [Linux] Avoid usage of <sys/sysctl.h> in MallocBench
Adrian Perez
Reported 2019-10-17 10:19:04 PDT
On Linux systems which use glibc ≥2.30 the following will be logged during compilation: In file included from ../PerformanceTests/MallocBench/MallocBench/CPUCount.cpp:29: /usr/include/sys/sysctl.h:21:2: warning: "The <sys/sysctl.h> header is deprecated and will be removed." [-W#warnings] #warning "The <sys/sysctl.h> header is deprecated and will be removed." ^ The release notes for glibc 2.30 read: “The Linux-specific <sys/sysctl.h> header and the sysctl function have been deprecated and will be removed from a future version of glibc. Application should directly access /proc instead. For obtaining random bits, the getentropy function can be used.” (See also https://sourceware.org/ml/libc-alpha/2019-08/msg00029.html for the full release notes.)

Turns out, usage of sysctl() is guarded with an “#ifdef __APPLE__” guard and in Linux the sysconf() function is used instead. Adding the same guard for the header inclusion should suffice.
