“If you get errors about missing AC_ macros, you may need to download a copy of libraries on which your tool depends and copy their .m4 autoconf configuration files into /usr/share/autoconf. Alternately, you can add the macros to the file acinclude.m4 in your project’s main directory and autoconf should automatically pick up those macros.”
So just add the libcurl.m4 file containing the AC_MSG_ERROR macro to the cpuminer-vert project directory and rename the file to “acinclude.m4” and proceed as per the README.
