nmap @7.95 cannot compile on macOS 15 Sequoia

[SaintBol]

Using Xcode clang compiler (Command Line Tools not present): cannot compile the port on macOS 15 Sequoia. Compiling with openssl installed.

Attached main.log

Error is a bit obscure («command failed»):

:info:build Command failed:  cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_net_nmap/nmap/work/nmap-7.95" && /usr/bin/make -j16 -w all 
:info:build Exit code: 2

Therefore I tried manually in the build directory just after the error:

It complains about aclocal-1.16 not being there, whereas aclocal-1.17 is actually there...

% port content automake | egrep 'aclocal-.*[0-9]{2}$'

/opt/local/bin/aclocal-1.17

FWIW, I just upgraded and build nmap locally without seeing this issue. I'll look some more once my normal set of installed ports finishes installing.

Replying to SaintBol:

Therefore I tried manually in the build directory just after the error:

We don't recommend this as a troubleshooting step. Running commands in the MacPorts work directory manually omits the sandboxing, environment variables, and arguments that MacPorts uses, so your results from building manually are not necessarily applicable.

Automake and Autoconf are installed:

automake                       @1.17           devel/automake
autoconf                       @2.72           devel/autoconf

This looks like output from port list. port list doesn't do what you think it does; see wiki:FAQ#portlist. Use port installed instead.

Many ports look for specific versions of automake, such as 1.16 which was the latest version for a long time, and need to be patched when we update to a new version of automake, as we recently did in #70408. Before that, I fixed all the references to automake 1.16 I could find, but I didn't do nmap.

[ryandesign (Ryan Carsten Schmidt)]

Like Daniel, I cannot reproduce this problem, but I am on macOS 12, and you are on macOS 15 which we already know has a number of problems.

[jmroot (Joshua Root)]

Has duplicate #70784.

A strategy that works well for me is to exclude all generated files from the repository by putting them in .gitignore, and then providing a robust autogen.sh. I'm not sure if there's a way to implement this for an arbitrary port, though.
