Linux ap3 6.6.61-0-lts #1-Alpine SMP PREEMPT_DYNAMIC 2024-11-14 20:10:08 x86_64 Linux

>Description:
Minimal Alpine Linux 3.20.3 install uses musl libc, "an implementation of the standard library functionality described in the ISO C and POSIX standards, plus common extensions, built on top of the Linux system calls API"

building security/openssl fails with linux/mman.h: No such file or directory

although /usr/include/sys/mman.h is available, it is not used.


>How-To-Repeat:
Minimal standard Alpine install, followed by "apk add build-base wget gawk" to enable pkgsrc bootstrap. bmake security/openssl fails.

>Fix:
configure should use the non GNU libs since they are provided; workaround, install functionality wrapper "apk add linux-headers"
