#3713 wxmaxima build failure with MacPorts

[Murray Eisenberg]

I'm following procedure at https://sourceforge.net/projects/maxima/files/Maxima-MacOS/5.44.0-MacOSX/ and in the readme.txt file there to install maxima with wxmaxima under MacPorts 2.6.99. This is under macOS BigSur 11.1 and with Xcode and Command Line Tools 12.

The build of the maxima port itself was OK. But the build of wxmaxim failed:

The full main.log is attached.

[Tomio Arisaka]

Thanks for the report.

I looked at the main.log.
Then I noticed that you used gcc10 to build wxmaxima.

:info:build -- The CXX compiler identification is GNU 10.2.0
  ...
:info:build -- Check for working CXX compiler: /opt/local/bin/c++ - skipped

I think that you should use Apple-Clang instead of gcc10.
So please check the default C++ with the command "port select --summary".

[Murray Eisenberg]

I do not know how to "use Apple-Clang instead of gcc10": as I reported, I'm using MacPorts, and the way to install the wxmaxima port is simply to execute: "sudo port install wxmaxima"; MacPorts infrastructure is supposed to take case of the rest. So the port as posted at the sourceforge page I originally cited needs some kind of revision.

[Tomio Arisaka]

I mean that Apple-Clang is the command 'clang' included in Xcode.

MacPorts can install multiple versions of software (e.g. gcc, perl, python).
Each of the executable file names is different in order to avoid the conflict.
Then it is useful that one of the versions is selected as default.
The command "port select" is the mechanism for it.

So I think that the command "sudo port select --set gcc none" works for you.
After that, clang is used instead of gcc10 to build wxmaxima.

The following example is a description of this command:

(0) The command "port help" shows the user action "port select":

   select
       For a given group, selects a version to be the default by creating
       appropriate symbolic links. For instance, python might be linked to
       python2.6. Available select groups are installed as subdirectories
       of ${prefix}/etc/select/ and can be listed using --summary. To list
       the available versions in a group, use --list. To see which version
       is currently selected for a group, use --show. To change the
       selected version for a group, use --set.

       For example:

           port select --summary
           port select --show python
           port select --list python
           port select --set python python34

(1) After installing gcc10

If you want to check the currently selected version, the following commands are available.

Hi Tomio, maybe you can you update the instructions for the MacPorts installation to say that one must use clang instead of gcc.
