Which version? 4.6.2?

You get message like "undefined reference to `vtable for octave_base_value'"
?

Qt 4.8.0 mingw installed in windows c:\Qt\4.8.0, and then the lib,include and bin folder copied over into mxe-octave/usr/i686-pc-mingw/

 

Likewise I installed ghostscript ghostscript9.07, and copied the gswin32c.exe to /usr/bin/gs.exe, and it seems to be good enough so far for working ghostscript

 

On another note, I am currently installing binutils and gcc from source outside of mxe-octave - its still compiling right now, however hasn't failed where it was when I was trying to make it in mxe-octave - something in mxe interfering?
