pango @1.42.3 does not build on PPC Tiger, Mac OS X 10.4.11, because something goes wrong bootstrapping makefile fragments

config.log contains this line:

config.status:1636: cd pango       && sed -e '/# am--include-marker/d' Makefile         | make -f - am--depfiles
/opt/local/share/gobject-introspection-1.0/Makefile.introspection:158: *** Need to define Pango_1_0_gir_LIBS or Pango_1_0_gir_PROGRAM.  Stop.
config.status:1641: $? = 2

So it's obvious that on Tiger Pango needs to be configured with the additional option --enable-debug=no instead of --enable-introspection.

Config.log from configuration attempt on PPC Tiger

It's sufficient to change in Portfile this line from yes to no:

     54 gobject_introspection   no

[ballapete (Peter "Pete" Dyballa)]

In my original report I meant of course to use --enable-introspection=no instead of using --enable-introspection.

The config.log says configure failed because:

/opt/local/share/gobject-introspection-1.0/Makefile.introspection:158: *** Need to define Pango_1_0_gir_LIBS or Pango_1_0_gir_PROGRAM.  Stop.

We've seen this error before at least; it happens because Tiger ships with GNU make 3.80, but gobject introspection requires 3.81. The last time this came up for pango was #35203, and we fixed it by having pango use the gmake port instead, on Tiger. Later, that was abstracted out into the gobject introspection 1.0 portgroup so that any port that needs gobject introspection can include it.

The new problem now is that pango seems to be trying to use make during the configure script, in this fragment of aclocal.m4:

    AM_RUN_LOG([cd "$am_dirpart" \
      && sed -e '/# am--include-marker/d' "$am_filepart" \
        | $MAKE -f - am--depfiles]) || am_rc=$?

It looks like this new aclocal.m4 was generated by aclocal 1.16.1, whereas pango 1.42.2's aclocal.m4 was generated by aclocal 1.15.1. This change wasn't mentioned in the pango NEWS or ChangeLog files; I guess they didn't think it was important.

On Tiger, the gobject introspection portgroup only knows to set build.cmd to the gmake port's gmake, which only affects the build phase, not the configure phase.

So it looks like in order to support Makefiles that use gobject introspection that were generated by automake 1.16 and later on Tiger, we need to set the MAKE variable at configure time too, in the gobject introspection 1.0 portgroup.

In cb45ca8440bf9f248307bcbd1419fa12df5bf612/macports-ports (master):

gobject_introspection-1.0.tcl: Set MAKE on Tiger

Fixes build failure of ports that use gobject introspection and automake
1.16 or later, including ports like pango that ship with Makefiles that
were generated with automake 1.16 or later, and ports like libgsf that
use autoreconf, since MacPorts automake is now 1.16.x.
