I've tried building https://ipmiutil.sourceforge.net/FILES/ipmiutil-3.2.1.tar.gz as suggested in #10 to find another problem: libipmiutil.so.1 is underlinked against -lcrypto; here's the complete build log (ALT Linux Sisyphus, x86_64, gcc 14.2.1, autoconf 2.71, automake 1.16, openssl 3.1.7).
OK, I have updated the ipmiutil-3.2.1.tar.gz to include -lcrypto in the library build.
I have included this in iipmiutil-3.2.1, just released. This works for me, but let me know to confirm that you don't have any issues with it.
Hm, libipmiutil.so.1 is still not linked against -lcrypto for me when building 3.2.1 release with gcc 14.2.1 on linux/x86_64:
