[Gnuplot-bugs] gnuplot 5.1 patchlevel 0 fails to compile with wxwidgets

[Alan F. <al...@co...>]

Hopefully this list is appropriate for this issue. Apologies if not.

I recently installed wxidgets-3.0.1 and gnuplot-5.1 to my 
LinuxFromScratch system. No apparent issues installing wxwidgets.

For installing gnuplot I followed instructions from:

http://www.gnuplot.info/
http://sourceforge.net/projects/gnuplot/files/gnuplot/
http://www.gnuplot.info/development/index.html

I did the following to get and compile the source code:

export 
CVSROOT=:pserver:ano...@gn...:/cvsroot/gnuplot
cvs login
cvs -z3 checkout gnuplot

ln -sfv qt5.conf /etc/xdg/qtchooser/default.conf
export QT_SELECT=qt5
ln -sfv /opt/qt5/lib/qt5/bin /opt/qt5/bin

./prepare
./configure --prefix=/usr --with-tutorial --disable-wxwidgets
make

This compiled successfully and executed the demo programs without issues.

However, without the --disable-wxwidgets switch make fails with:

I have no clue what to do about the above. Is there a bug in the 
compilation software for wxwidgets or gnuplot? I've not found anything 
on Google.

Thanks,
Alan
