Ah, good idea Dan.

make 2>stderr.log

redirecting stderr to a file and searching for "error" found this. It 
seems it is doing an ungodly mix of gtk2.0 and gtk3.0

=============

This is probably since I had to provide it with a WXDIR since it could 
not find it on its own.

However the only wx-config on the system is that which I gave it :
/usr/libexec/wxGTK3/wx-config

If I don't give it a WXDIR in configure it configures to build without wxt.

Fedora seems to offer some kind of gtk3-gtk2 compatability lib , 
installing this got a bit further:

Installing:
  compat-wxBase3-gtk2          x86_64     3.0.2-5.1.fc23        fedora 
    1.1 M
  compat-wxGTK3-gtk2           x86_64     3.0.2-5.1.fc23        fedora 
    5.4 M
  compat-wxGTK3-gtk2-devel     x86_64     3.0.2-5.1.fc23        fedora 
    1.3 M
  compat-wxGTK3-gtk2-gl        x86_64     3.0.2-5.1.fc23        fedora 
     35 k
  compat-wxGTK3-gtk2-media     x86_64     3.0.2-5.1.fc23        fedora 
     56 k

I still need to tell it where to find wx-config otherwise it builds 
without wxt

./configure --prefix=/usr/local --without-qt 
--with-wx=/usr/libexec/compat-wxGTK3-gtk2/

Now it seems to fail at the linker stage.

/bin/ld: wxterminal/wxt_gui.o: undefined reference to symbol 'XInitThreads'
/usr/lib64/libX11.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make[4]: *** [gnuplot] Error 1


I'm a bit included just to give up on wxt and use qt, but from a 
development point of view I suppose this should work.

I don't think I'm trying to do anything particularly odd-ball here. Any 
suggestions?

Thanks,  Peter.
