Hi Alan,
I attempted to install Plplot-15-5.0 on my Ubuntu 18.04 Linux machine, but
cmake could not find where the cairo, qt, tk,etc. libraries were located for
some reason. Rather than attempting to deal with those issues, ....
Hi John:
Well, the usual issue when CMake cannot find libraries is the
"development" versions of the cairo, qt, and tk library packages have not been
installed. Which should be an easy problem to fix....
However [when attempting to use 3rd-party PLplot for a later Ubuntu], it would be nice if the xwin option also worked.
Currently, when I select that option, I get the error: "*** PLPLOT ERROR,
IMMEDIATE EXIT *** Can't open display Program aborted." I am guessing that
I am missing something simple in how the X environment is specified. Might
you have any suggestions for resolving that issue?
Actually, I have never had a problem like that with -dev xwin so you
might be up against a packaging error of some kind. To confirm or
eliminate that possibility, what happens for the version you build
yourself (as above, but with all relevant library development packages
installed)?
If the version you build yourself also has the problem, then I suggest
you try the -debug option which should give more details on what
exactly is going wrong for -dev xwin.
Good luck, and let us know how it goes.
Alan
