[BUG] sys/sysctl.h is deprecated in glibc-2.3.2

[espenhgn]

Describe the bug
Dear @choishingwan.
The deprecated sys/sysctl.h is used in a few places across the PRSice codes, preventing compilation of the project.

Error Log
Compilation error running make:

To Reproduce

Try build the following Dockerfile (some work in progress virtual machine, based on Ubuntu jammy (22.04LTS):

# R container
FROM rocker/r-ver:4.3.1

ENV TZ=Europe
ENV DEBIAN_FRONTEND noninteractive

WORKDIR /tmp/

Hi again, just to add a bit more context. I'm trying to provide a cross-platform solution for PRSice2 etc. including M1 Macs via Docker (arm64-based architecture). I could get the compilation to work now on this rocker/r-ver:4.3.1 base image (based on Ubuntu 22.04 LTS) on a x86_64 host machine by removing #include <sys/sysctl.h> and replacing #include <Eigen/Dense> by #include <eigen3/Eigen/Dense> across inc/*.h files, but still encountered an issue that I couldn't resolve with the arm64 based platform in a Plink derived file:

(similar to an older version of https://github.com/chrchang/plink-ng/blob/master/1.9/plink_common.h I presume)

Do you think it is feasible to provide better "official" support on M1/arm64-based architectures, as well as more recent OS such as Ubuntu 22.04 (LTS)?

[chrchang]

fyi, recent plink 1.9 builds use the SIMDe library (https://github.com/simd-everywhere/simde ) to support ARM builds; see lines 190-195 of the current plink_common.h .
