#196 make problems while installing Gnuplot 5.0.1 on Ubuntu 14.04

[Anonymous]

Hi,

I am struggling with the installation of Gnuplot 5.0.1 on my Ubuntu 14.04 LTS machine. The configure, make and make install run smoothly, as long as I don't want to include pdfcairo. As soon as I have installed pdfcairo, the configure still runs, but during the make I get the following error message:

c++ -g -O2 -I/usr/lib/x86_64-linux-gnu/wx/include/gtk2-unicode-3.0 -I/usr/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread -pthread -I/usr/include/cairo -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/pango-1.0 -o gnuplot alloc.o axis.o breaders.o boundary.o color.o command.o contour.o datablock.o datafile.o dynarray.o eval.o external.o fit.o gadgets.o getcolor.o graph3d.o graphics.o help.o hidden3d.o history.o internal.o interpol.o libcerf.o matrix.o misc.o mouse.o multiplot.o parse.o plot.o plot2d.o plot3d.o pm3d.o readline.o save.o scanner.o set.o show.o specfun.o standard.o stats.o stdfn.o tables.o tabulate.o term.o time.o unset.o util.o util3d.o variable.o version.o wxterminal/wxt_gui.o wxterminal/gp_cairo.o wxterminal/gp_cairo_helpers.o -lreadline -ltermcap -lz -L/usr/lib/x86_64-linux-gnu -pthread -lwx_gtk2u_xrc-3.0 -lwx_gtk2u_html-3.0 -lwx_gtk2u_qa-3.0 -lwx_gtk2u_adv-3.0 -lwx_gtk2u_core-3.0 -lwx_baseu_xml-3.0 -lwx_baseu_net-3.0 -lwx_baseu-3.0 -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0 -ldl -lm -lz -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0

//usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line

The only way of getting rid of this that I could figure out until now was to remove the libx11-dev completely and ro reinstall it afterwards without installing pdfcairo.

Any suggestions would be highly appreciated.

Thanks!

pdfcairo should not make that problem, it's the cairo-based interactive wxt terminal. You can follow the advice from the release notes and run

 TERMLIBS="-lX11" ./configure && make && ...

or

configure --with-X11

or

configure --with-wx-single-threaded

or switch off building the wxt terminal and use qt for interactive work. It's in my experience substancially faster, too.

. The second option above should help, but to me sometime didn't. The problem lies somewhere in the multithreading of libwxt3.

Same on Ubuntu 15.10. I edited the respected makefiles and added a -lX11 flag to the LIBS variable. See http://knanagnostopoulos.blogspot.gr/2016/02/ubuntu-1510-compiling-gnuplot-50-tweaks.html
