This appears to be a universal build of cmake-bootstrap.

So far I can't reproduce this... so we'll see how things play out for a while.

[kencu (Ken)]

On my arm Mac, builds through without any intervention.

% port -v installed cmake-bootstrap
The following ports are currently installed:
  cmake-bootstrap @3.9.6_0+universal (active) requested_variants='+universal' platform='darwin 22' archs='arm64 x86_64' date='2023-03-09T13:20:17-0800'

[kencu (Ken)]

In a4fda7b98703ff055b9dacb7e1dca58d5376d490/macports-ports (master):

cmake-bootstrap: disable universal variant

this port does not need to be universal, being a
build tool without libraries, and trying to build
it universal can cause errors

closes #66213
closes #67072

On an arm'ed MB, M1 Max with Sequoia, I have a similar problem after failed migration.

:info:configure Error when bootstrapping CMake:
:info:configure Cannot find appropriate C++ compiler on this system.
:info:configure Please specify one using environment variable CXX.
:info:configure See cmake_bootstrap.log for compilers attempted.

When trying to configure and gmake manually, I run into the error:

[ 55%] Building CXX object Source/CMakeFiles/CMakeLib.dir/LexerParser/cmCommandArgumentLexer.cxx.o

Changed line 6 in cmake root tree the Source/cmStandardLexer.h Downloaded version:

#include "cmConfigure.h" // IWYU pragma: keep */

Changed, by capturing the absolute path:

#include "/opt/local/var/macports/build/_opt_local-new_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_cmake-bootstrap/cmake-bootstrap/work/cmake-3.9.6/Bootstrap.cmk/cmConfigure.h" // IWYU pragma: keep

It's not the elegant way, but gmake was then running successful.

it is strange how weird idiosyncracies develop on some people’s machines.

so long as this is the only one time you have to do this, it’s probably OK.

however, any further similar weirdness and you’ll need to figure out exactly what is wrong on your system.

I’d run “port doctor” and “port reclaim” just to clean up…
