Hi All,

We’re seeing a lot of subdirectory warnings when installing FreeSWITCH 1.6.19 from source.

The warnings aren’t critical and the installation still completes.

We can add to subdir-objects to AM_INIT_AUTOMAKE in each of the configure.ac files as a workaround so it completes without these warnings, but should these subdirs be included or are these warnings to be expected?

As follows.

curl https://files.freeswitch.org/repo/deb/debian/freeswitch_archive_g0.pub | apt-key add -

echo "deb http://files.freeswitch.org/repo/deb/freeswitch-1.6/ jessie main" > /etc/apt/sources.list.d/freeswitch.list

apt-get update && apt-get upgrade

apt-get install -y --force-yes freeswitch-video-deps-most

cd /usr/src

rm -R freeswitch

cd freeswitch
