looks like it wants a newer compiler.

[josephsacco]

Maybe... With a little "persuasion". The makefiles generated by configure, include the line:

CFLAGS = -pipe -Os -F/opt/local/library/Frameworks -m32 -ObjC

The last piece in CFLAGS, "-ObjC" causes gcc-7 to barf.

Hmmm... Wonder what happens if I modify configure?

Stay tuned...

[josephsacco]

build log: gcc-7 , configure patched to eliminate "-ObjC"

[josephsacco]

It would appear that gcc-7 is very unhappy with the OS X 10.5.8 Foundation framework.

Using the "hammer and tongs" approach:

• Use gcc-7
• eliminate AquaTerm

gnuplot actually builds.

However... "make check" fails with malloc error "Non-aligned pointer being freed"

Sigh...

mmm. It just installed without any trouble for me:

$ port -v installed gnuplot
The following ports are currently installed:
  gnuplot @5.0.6_1+aquaterm+luaterm+pangocairo+wxwidgets+x11 platform='darwin 9' archs='ppc' date='2017-07-05T16:03:05-0700'
  gnuplot @5.2.0_0+aquaterm+luaterm+pangocairo+wxwidgets+x11 platform='darwin 9' archs='ppc' date='2017-09-20T15:29:30-0700'
  gnuplot @5.2.1_0+aquaterm+luaterm+pangocairo+wxwidgets+x11 platform='darwin 9' archs='ppc' date='2017-11-05T16:50:30-0800'
  gnuplot @5.2.2_0+aquaterm+luaterm+pangocairo+wxwidgets+x11 platform='darwin 9' archs='ppc' date='2017-11-17T19:26:46-0800'
  gnuplot @5.2.3_0+aquaterm+luaterm+pangocairo+wxwidgets+x11 (active) platform='darwin 9' archs='ppc' date='2018-05-26T19:16:57-0700'

Dunno. I will try "make check" and see what that gives us...

[kencu (Ken)]

well I can't easily do "make check" as there's no test phase in the port just now, but gnuplot runs on 10.5 PPC without crashing for me...

[kencu (Ken)]

Here are your variants

gnuplot-5.2.3_0+aquaterm+luaterm+pangocairo+wxwidgets+x11

and they look identical to the defaults:

gnuplot @5.2.3_0+aquaterm+luaterm+pangocairo+wxwidgets+x11

Why don't you uninstall it, clean, and try the install again?

[josephsacco]

Ken,

You are correct.

I first uninstalled and then reinstalled one of the "suspect" build dependencies, wxWidgets-3.0, which thankfully was available pre-compiled from packages.macports.org. I then cleaned gnuplot-5.2.3_0 and installed it in "keep mode", to have access to the build tree. Once the install completed, I then ran "sudo make check" in the build directory. The rather extensive, visually stunning test suite ran without incident. "We" are pleased.

One of the difficulties of developing software on an ancient PPC-based MAC is the amount of random-J cruft that has accumulated over the years. There was clearly something amiss with the version of wxWidgets-3.0 I had installed back in March of this year.

Kindly mark this ticket as "pilot error".

Onwards,

-Joseph

Excellent.
