autoreconf error, 2.69
I have cloned libgpiod from this web site (brgl/libgpiod). I am having problems building libgpiod. I am running the software on a Raspberry PI 3B+ using Raspbian Buster OS. I have successfully used sysfs in the run-time of my event-driven language immediate C for over 8 years to set GPIO outputs and generate interrupts from GPIO inputs and read them. Since sysfs is deprecated I want to migrate my code to libgpiod.
I installed the following:
apt install autoconf
apt install autoconf-archive
I initially executed:
sudo apt install gpiod libgpiod-dev libgpiod-doc
Trying to compile examples from that install showed that the gpiod.. C functions were not present. I then cloned libgpiod.
Following the Build instructions I executed:
./autogen.sh --enable-tools=yes --prefix=/usr/local
This output the following error messages:
autoreconf: Entering directory .'

I do not know to what path or where exactly to set LT_INIT

Could you check whether you have libtool installed?
No libtool found.
I have now done
sudo apt install libtool
This adds the directory /usr/share/libtool
./autogen.sh --enable-tools=yes --prefix=/usr/local seems to be working except for the following warning:
autoreconf: running: aclocal --force -I m4
aclocal: warning: couldn't open directory 'm4': No such file or directory
make OK Vielen Dank, John
make install fails because it requires super-user privileges.
sudo make install OK
You may want to modify the Build instructions in the README.
