compiling with musl on Alpine Linux

[commandline-be]

Building openscap.git on Alpine Linux 3.7 does not work well, i assume this may be because of missing libraries or ... musl

required to do before starting compilation

apk add dbus-dev libacl libcap-dev curl-dev libgcrypt-dev libxml2-dev libxslt-dev make openldap-dev pcre-dev perl-xml-parser perl-dev python-dev swig bzip2-dev util-linux-dev dpkg-dev gconf-dev attr-dev wget lua which procps build-base cmake python3-dev

to avoid some warnings to pop up

prepending on the first line of the Makefile.am listed below
AUTOMAKE_OPTIONS = subdir-objects
to the various Makefile.am resolves any warning regarding

Makefile.am:AUTOMAKE_OPTIONS = subdir-objects
src/OVAL/Makefile.am:AUTOMAKE_OPTIONS = subdir-objects
src/OVAL/probes/Makefile.am:AUTOMAKE_OPTIONS = subdir-objects
src/OVAL/probes/SEAP/Makefile.am:AUTOMAKE_OPTIONS= subdir-objects
src/OVAL/probes/SEAP/generic/rbt/Makefile.am:AUTOMAKE_OPTIONS= subdir-objects
tests/oscap_string/Makefile.am:AUTOMAKE_OPTIONS = subdir-objects
tests/API/XCCDF/unittests/Makefile.am:AUTOMAKE_OPTIONS = subdir-objects

next

./autogen.sh

next

./configure --enable-python3

next

make

results in a slew of notifications starting with

openscap is now available in testing repository of Alpine Linux:
https://pkgs.alpinelinux.org/package/edge/testing/x86_64/openscap

You can check the APKBUILD to see how the compilation has been done succesfully:
