On debian 11 configure.ac requires autoconf version 2.71 but latest version on current debian 11 is 2.69

[marcelloc]

cd /usr/src/spandsp/
./autogen.sh
configure.ac:21: error: Autoconf version 2.71 or higher is required

dpkg -l | grep autoconf
ii  autoconf                              2.69-14  

edit configure.ac
change AC_PREREQ([2.71])) to 2.69 version
save file
compile and install

./autogen.sh
./configure
make
make install

Then, rerun install script if you are compiling spandsp on fusionpbx install.
cd /usr/src/fusionpbx-install.sh/debian && ./install.sh

Thanks for sharing this Marcello. I've also seen this problem on Debian 11 here is a sed command to change it from 2.71 to 2.69

cd /usr/src/spandsp/
sed -i 's/AC_PREREQ([2.71])/AC_PREREQ([2.69])/g' configure.ac

I will add it to the FusionPBX install script. Until the code gets fixed.
