As suggested by the webmaster
sudo apt install automake libtool m4 autoconf
I found that all of them are installed. Try other solutions:
The software installed by apt-get is usually in the /usr directory. Since it is prompted that AC_PROG_LIBTOOL cannot be found, there are two general reasons for the analysis.
1. failure to install the package or other reasons such as version problems resulting in no definition of AC_PROG_LIBTOOL.
2. there is a problem finding the path.
From these two points, you can look for AC_PROG_LIBTOOL globally in the /usr directory


can see that AC_PROG_LIBTOOL can be found in the m4 file, then it may be a path issue.
Most m4 files are in the /usr/share/aclocal/ directory, but the default aclocal path for configure is actually /usr/local/share/aclocal.
Then there can be two ways to do it.
First, copy all the *.m4 files under /usr/share/aclocal/ to the usr/local/share/aclocal/ directory.
Second, specify the installation path of aclocal.
sudo cp /usr/share/aclocal/*.m4 /usr/local/share/aclocal/
Again . /autogen.sh, and it passes.
