gnuplot: Unable to install with +wxwidgets variant

[vidakris]

sudo port install gnuplot +wxwidgets

gives the following error:

Error: Cannot install gnuplot for the arch(s) 'x86_64' because
Error: its dependency wxWidgets is only installed for the arch 'i386'
Error: and does not have a universal variant.
Error: Unable to execute port: architecture mismatch

After the previous fix, port install will start, it gives however the following error:

Error: Target org.macports.build returned: shell command failed (see log for details)

main.log is attached.

Ok, that's a different problem. I'm able to reproduce it on Snow Leopard with Xcode 3.2.6 if I request the use of llvm-gcc-4.2 or clang. By default MacPorts compiles using gcc-4.2 on Xcode 3.2.x which works fine. But because you're on Xcode 4.1.x the default is llvm-gcc-4.2. Try using gcc-4.2 instead:

sudo port clean gnuplot
sudo port install gnuplot +wxwidgets configure.compiler=gcc-4.2

OK, now it compiles all right. Wx terminal is still useless unfortunately. Plotting works fine, but the color wheel keeps spinning, and the window won't react on clicks, so no interactive functions work. But that's another topic.

Replying to vidakris@…:

The reason why installing gnuplot 4.4.4 with +wxwidgetss fails for me is a bug in autotools used for preparing gnuplot's configure script. (I asked gnuplot developers to upgrade and they will hopefully use a newer version for next release.) After using the patch from #33596 I have no problem compiling with XCode 3.2 on 10.6 both clang and llvm-gcc-4.2, as well as on 10.7 and XCode 4.2.1 (again, both with clang and llvm-gcc-4.2). The only combination that fails is compiling with wxwidgets-devel and clang compiler, which is why I have used

if {[variant_isset wxwidgets_devel]} {
    # http://trac.wxwidgets.org/ticket/13565
    if {${configure.compiler} == "clang"} {
        configure.compiler llvm-gcc-4.2
    }
}

In principle I can backport the patch for 4.6.0 to 4.4.4, but I see no compelling reason to do so unless somebody tells me to do it (that is: if upgrading to 4.6.0 is not feasible for one reason or the other). If anyone else would want to backport the patch, simply take a look at lines around "bool e = &s;" in configure script in ​gnuplot4_6_0-v2-cocoa.diff

Wx terminal is still useless unfortunately. Plotting works fine, but the color wheel keeps spinning, and the window won't react on clicks, so no interactive functions work. But that's another topic.

Gnuplot 4.6.0 (#33596) solves that problem as well. So according to my knowledge, once patches from ticket #33596 are applied, this ticket could be closed as well.
