This appears to be a gcc-4 versus gcc-3 issue.

By default in 10.4, gcc means gcc-4.0 -- changing this to gcc-3.3 causes the gnuplot port to build and work without any problems at all.

I'm not up on what needs to be changed to make gcc-4 happy with the code (i.e. the real fix) so I just built my version of the port with gcc-3. Not a true solution, but hopefully should point to one.

Another way of solving the bug is to compile without X11 support. Adding +no_x11 to /opt/local/etc/ ports/variants.conf solves the problem.

GNUplot will then use AquaTerm and not X11. This could cause problems if you need X11 for features like mouse zooming, etc.

My workaround for this bug is a bit un-DarwinPort like (i.e.ugly):

1) port build gnuplot: this will fail as above.

2) remove -ObjC from src/Makefile's CPPFLAGS: Objective C is no longer needed at this point.

2) port install gnuplot: this now finishes the compile.

I am just confirming that gnuplot built succesfully using 'port install gnuplot +no_x11'

The attached portfile patch and patchfile allow gnuplot +x11 to build on tiger.

I took the (trivial) fix from gnuplot CVS, see:
