How to install "autom4te" on Alpine Linux

Problem:

When trying to build applications on Alpine Linux, you sometimes see messages like

sh: autom4te: not found
aclocal: error: autom4te failed with exit status: 127

but when you try to apk install autom4te you see that the package can not be found:

fetch https://dl-cdn.alpinelinux.org/alpine/v3.17/main/x86_64/APKINDEX.tar.gz
fetch https://dl-cdn.alpinelinux.org/alpine/v3.17/community/x86_64/APKINDEX.tar.gz
ERROR: unable to select packages:
  autom4te (no such package):

Solution:

autom4te is available from the autoconf package. Therefore, in order to fix the issue, you can run

apk install autoconf
