#2 CMake doesn't find PGPlot on a MacBook

[Anonymous]

I'm attempting to install evtools ver. 0.4.1 on a MacBook Pro running Mac OS X ver.10.11 (El Capitan). I'm using gfortran ver. 4.9.2 and running CMake ver. 3.4.2. The problem I'm having is that cmake's makefile is not picking up the location given for pgplot. The cmake application says it can find pgplot, but the command line command cmake can't find it.

Any suggestions?

[AstroFloyd]

Could you post the command-line output from the cmake and make commands? Also, where on your filesystem are your libpgplot.so and cpgplot.h located? Please add an attachment for long output.

I have libpgplot.a and cpgplot.h installed in /Users/user/pgplot531_gfortran. I went into ccmake and ater a few tries finally got cmake to recognize my pgplot library and include file locations (see the attached file). The problem is getting the linker to resolve what it believes to be are missing object files that I suspect are from X11. It seems I can't get cmake to point to my X11 libraries at /opt/X11.

Any thoughts?

[AstroFloyd]

I think this is an issue in your PGPlot installation - the library (libpgplot.a) doesn't seem to be linked against X11. I once found a similar issue with PGPlot in Arch Linux. The solution there was to add the "-lX11" flag to the make command:

$ make FCOMPL=gfortran SHARED_LIB_LIBS="-lpng -lz -lX11" all

(or edit the PGPlot Makefile and add it). Have you installed PGPlot manually or using e.g. Darwin Ports (it can be a pain)? Have you used it (succesfully) elsewhere?

Also, you mention libpgplot.a (the static library) - you should have a libpgplot.dylib (the dynamic or shared library - forget about the .so; my mistake), i.e. in the same dir to make life easier. I remember (from notes) that after the make step above, I had to do:

$ make clean
$ make CFLAGS="${CFLAGS} -fPIC" FFLAGS="${FFLAGS} -fPIC" shared

If this doesn't work, edit the makefile and add the -fPIC flags to the appropriate lines. The target "shared" may actually be called something like "pgplot.so".

I'm having trouble with linking X11 with evtools.

First, I found a procedure to build PGPlot in MacOS X that seems to work
well:

http://mingus.as.arizona.edu/~bjw/software/pgplot_fix.html
http://mingus.as.arizona.edu/%7Ebjw/software/pgplot_fix.html

Second, pointing cmake to /usr/local/lib/pgplot, I get the following

I'm still not able to build a shared PGPlot library.

Any suggestions?

I checked my notes on installing PGPlot and posted them on my blog.

[AstroFloyd]

The instructions you mention to build PGPlot also contain a method to create the shared library:

If for some reason you need to make the libpgplot.so shared object (dynamically loaded) library, you should be able to do this by uncommenting the lines in the .conf file (gfortran_gcc_32.conf or similar) that read SHARED_LIB="libpgplot.so" and SHARED_LD="gcc -shared -o $SHARED_LIB", before running the "makemake" step.

Doing that, and commenting out the other occurences of these two variables, allowed me to generate a shared library using the macos config file using "make shared". The command "ldd libpgplot.so" also shows that the library is linked against libX11.

If you insist on linking statically, the build tools provided with evtools are not going to help, and you'll have to write your own Makefile. The MacOS instructions give some idea how to do this - translated to gfortran and multiple source files:

gfortran -o myprog myprog1.f90 myprog2.f90 /usr/local/lib/pgplot/libpgplot.a /usr/X11/lib/libX11.dylib

My experience is that a .a file should be processed like a .o file, and that the order is important(!)

[astro-boy]

I've be able to rebuild PGPLOT with both shared and static libpgplot
files. I'm now able to successfully build evtools on my MacBook Pro. The
remaining question I have is locating documentation for evtools. I found
a link for ev documentation at
https://www.ualberta.ca/~ivanova1/astro465_2012.html
https://www.ualberta.ca/%7Eivanova1/astro465_2012.html. I can't get to
the documentation at this link, so is there an alternate URL you can
refer me to, or would you send me the documentation as an email attachment?

Thanks for all your help.
