Expat must be installed prior to building XML::Parser and I can't find
it in the standard library directories. Install 'expat-devel' (or
'libexpat1-dev') package with your OS package manager. See 'README'.

Or you can download expat from:

http://sourceforge.net/projects/expat/

If expat is installed, but in a non-standard directory, then use the
following options to Makefile.PL:

    EXPATLIBPATH=...  To set the directory in which to find libexpat

    EXPATINCPATH=...  To set the directory in which to find expat.h

For example:

    perl Makefile.PL EXPATLIBPATH=/home/me/lib EXPATINCPATH=/home/me/include

Note that if you build against a shareable library in a non-standard location
you may (on some platforms) also have to set your LD_LIBRARY_PATH environment
variable at run time for perl to find the library.

Does the build create any type of config.log file? If so, attach it. Without that, it's difficult to know why it couldn't find expat when it's there.

Let me begin with the obvious question: does /opt/local/bin/gcc-apple-4.2 exist and work?

I only looked for that file, did not use find, and did not see it…

Let me begin with the obvious question: does /opt/local/bin/gcc-apple-4.2 exist and work?

Yes. Both is true. Right now, and one or two days on, it is upgrading GCC7.

[ballapete (Peter "Pete" Dyballa)]

The build is now at stage 2 in ppc-apple-darwin8/libstdc++-v3.

[ballapete (Peter "Pete" Dyballa)]

No file config.log is created. I think it would be created when the make command would find the target ‘all’… So presumingly Tiger's make 3.80 is a bit too old (gmake is 4.4.1). I tried to port -vd upgrade p5.34-xml-parser MAKE=gmake but this failed…

[ballapete (Peter "Pete" Dyballa)]

After some days I found that port -vsd build p5.34-xml-parser build.cmd=gmake would substitute make with gmake – and it worked:

But still no config.log file…

[ballapete (Peter "Pete" Dyballa)]

On Sonoma 14.2.1 after port -vsd build p5.34-xml-parser the following command

find /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_perl_p5-xml-parser -type f -name "*.log" -ls

finishes without any output.This port seems to be debug proof…

Right, running a command yourself on the command line is not the same as MacPorts running it when you omit a lot of the things MacPorts did. In this case, the most relevant omission is that you did not set the CC environment variable which is what Makefile.PL is passing to ParseWords. Since that environment variable wasn't set, the value that ParseWords sees is uninitialized, and the rest of the script fails. (You are setting CC as a command line argument but that's not the same as an environment variable.)

Sure, that won't work. MacPorts doesn't automatically take arguments that you pass to the port command and pass them as arguments or environment variables to the build phase.

Replying to ballapete:

After some days I found that port -vsd build p5.34-xml-parser build.cmd=gmake would substitute make with gmake – and it worked:

Yes, you can specify MacPorts Portfile options like build.cmd on the command line to override the defaults, for debugging purposes. But the problem here isn't that a Makefile was generated that is incompatible with your version of make. The problem is that no Makefile was generated at all due to the failure to find expat.

This bug looks like #64543 again, which was fixed by using the compiler specified in the CC environment variable. Previously it would have used whatever compiler perl had been built with, and the problem with that was that the compiler that had been used to build perl on, for example, Snow Leopard, was a newer MacPorts version of clang which was not necessarily installed anymore at the time that a perl module was being built.

We really need to see what's happening in Makefile.PL as it runs, and since it doesn't generate a config.log for us, maybe we'll have to do ourselves. I added the p5-devel-dumptrace port which provides a module for printing information about each line of a perl script as it's executed. Wait at least an hour from now and then run:

sudo port clean p5.34-xml-parser
sudo port sync
sudo port install --unrequested p5.34-devel-dumptrace
sudo port configure p5.34-xml-parser configure.pre_args='-d:DumpTrace Makefile.PL'

When this fails, please attach the main.log file so that we can inspect the output. There will be a lot of output so attaching the main.log is better than pasting its contents into a comment.

[ballapete (Peter "Pete" Dyballa)]

My test and answer will come in one or two weeks, because now I am upgrading ports on Leopard. But here the same failure could happen…

[ballapete (Peter "Pete" Dyballa)]

On PPC Leopard, Mac OS X 10.5.6, it installs/upgrades without problem.

On Leopard py-bootstrap-modules is defective so that no Python 3.11 module can be built (meson, py311-meson, py311-markupsafe) and many ports cannot be built without meson and support does not seem to exist, so I am back at Tiger. The first three commands succeeded, the last one failed, as usual:
