Install GNU m4 1.4.19 on Ubuntu 18.04-CodePudding

I need to update m4 to 1.4.19 on Ubuntu 18.04, but how to do this ? This is a follow up from https://stackoverflow.com/a/69195008/1079990

I did:

wget ftp.gnu.org/gnu/m4/m4-1.4.19.tar.gz 
tar -xvzf m4-1.4.19.tar.gz 
cd m4-1.4.19/ 
./configure --prefix=/usr/local/m4 
make
sudo make install  # <-- suggested by @git-bruh
export PATH=/usr/local/m4/bin:$PATH
export PATH=/usr/local/m4:$PATH

But Ubuntu 18.04 still uses 1.4.18

Update after accept answer

But I still run into follow up error

CodePudding user response：

It would be better to go for a distro package as manually overwriting files managed by the package manager is not a good idea, but if you still want to overwrite them you need to build it like this:

./configure --prefix=/usr # Install to /usr/bin as that path has precedence over /usr/local
make
sudo make install

Instead of this you could just install to /usr/local and export PATH=/usr/local/bin:$PATH to use the new m4 without overwriting files. Note that the PATH must be set in every shell where the new m4 needs to be used.
