I tried to compile gnuplot with wxt on Windows by MingW, but it failed. How 
can I do it? I did the following:

I have downloaded the files below from 
	http://www.gtk.org/download-windows.html
and unzipped them into the MingW32 directory:

	cairo-dev-1.6.4-2.zip
	cairo-1.6.4-2.zip
	glib-dev_2.18.0-1_win32.zip
	glib_2.18.0-1_win32.zip
	pango-dev-1.20.5.zip
	pango-1.20.5.zip

>From the wx homepage I've got and unzipped into D:/wxMSW-2.8.8
	wxMSW-2.8.8.zip
These are source code. Unfortunately I couldn't compile it, the make always 
failed in some part of its makefile.gcc. I couldn't repair it. Any idea what 
to do?


Anyway, I proceeded further. In gnuplot's makefile.mgw, I had to change:
ifdef WXT
        CFLAGS += -DWXWIDGETS -ID:/wxMSW-2.8.8/include
        CFLAGS += -ID:/Apps/MingW32/MingW344/include/cairo
        CFLAGS += -ID:/Apps/MingW32/MingW344/include/glib-2.0
        WX_OBJS = wxt_gui.o gp_cairo.o
endif

because there is nothing like "wx-config" and "pkg-config" on my PATH as 
shell'ed from makefile.mgw.

In gnuplot/src/wxterminal/wx_gui.cpp, I had to uncomment this code:
#ifdef __WXMSW__
                /* the following is done in wxEntry() with wxMSW only */
                wxSetInstance(GetModuleHandle(NULL));
                wxApp::m_nCmdShow = SW_SHOW;
#endif
because wxSetInstance() was not known.

Then the compilation
    make -f makefile.mgw
worked.

But linking does not work, it complains about many undefined references. It 
seems wgnuplot.exe wants to be linked against the wx library. But it was not 
available as I couldn't compile it. I though the library may not be needed 
and some dll's could be used instead -- Michael's wgnuplot has dependencies 
to many dll's.

Could somebody describe a procedure how to compile wxt under MingW? How to 
have it static or with dll's?

Thanks.
