[Plplot-general] Ada to AquaTerm

[Marius Amado-A. <ama...@gm...>]

Hello.

I want to plot from Ada to AquaTerm (or to PS/PDF directly).

Is there a five or less steps setup process for this?

Already installed and running on my iBook G4 / Mac OS X 10.4 are:
- GNAT GPL 2007
- AquaTerm application
- AquaTerm "Developer Extras" with their "adapters" (but Ada missing)

Downloaded:
- plplot-5.9.0

Actually I'd be happy with just calling AquaTerm, but I understand
that the only Ada binding is through PLplot (?)

Thanks a lot.

If you want PS directly, then you might want to use the psc PLplot device
driver (no extra external prerequisites, but the hinted Type 1 fonts that this
device driver uses have rather limited glyph selection), psttfc device
driver (liblasi, pango and cairo prerequisites using TrueType fonts with
normally extensive glyphs available, but liblasi does not allow hinting to
be done), or pscairo (pango and cairo prerequisites using TrueType fonts
with hinting). If you want PDF directly, then use pdfcairo (same
prerequisites and font selection as pscairo).

Follow the directions in http://www.miscdebris.net/plplot_wiki/ to build
PLplot.  For the initial configuration stage using the cmake command, and
look carefully at the output for any warnings about missing dependencies
that affect (a) the aquaterm device driver, (b) the psttf device driver, or
(c) the cairo device driver.  Install the needed development versions of
those external libraries and interate using the cmake command (starting with
an empty build directory each time) until all warnings about devices you
care about are gone.  Then proceed with the "make", (optional) "ctest", and
"make install" steps.

Ok, trying this much more than five steps process.

Installed cmake.

Now the example commands don't work by the letter (e.g. file
plplot_cmake does not exist). So the assumptions begin.

Assumption 1. the cmake command

plplot_dir/build_dir>sudo cmake -DCMAKE_INSTALL_PREFIX=/plplot
-DCMAKE_VERBOSE_MAKEFILE=ON -DENABLE_ada=ON ..

This gives some errors and warnings, including

"WARNING: gnat library not found. Disabling ada bindings"

I got GNAT. How do I make it known to cmake?

Thanks.

On my Debian testing system the full pathname of the gnat library is
/usr/lib64/libgnat.so. What is the exact full pathname of the gnat library
on your platform?  Use the CMAKE_LIBRARY_PATH environment variable (as
documented in our Wiki) to inform cmake where the gnat library is located on
your system (assuming it is not in a standard location that CMake already
knows about).

Cmake reports:

...
CMAKE_C_COMPILER CMAKE_C_FLAGS:                 /usr/bin/gcc
CMAKE_CXX_COMPILER CMAKE_CXX_FLAGS:             /usr/bin/c++
...

Assumption 3. these things called FLAGS are not FLAGS but PATHS to the
compilers used by cmake

(My compilers are in /usr/local/ada-4.3/bin/)

No luck.

Giving up on plplus now.

Thanks.

 Good question :-)

 I installed GNAT 4.3 from MacAda.

 It is working fine. The binaries (gcc, gnatmake, etc.) are all in
 "usr/local/ada-4.3/bin"

 Assumption 2. everything GNAT is under "/usr/local/ada-4.3/"

 Assumption 2a. the "gnat library" is there too

 Now there is only 837465 paths to try...

I'm sorry that you haven't been able to get PLplot installed. I have  
two further comments, one for you if you want to keep listening in on  
this thread if it continues, and one for the list:

I'm no expert on installation issues but I've managed to write a bash  
script that gets the job done (with an exception-- see below) on  
Macs. I'd be glad to share it with you or post it to the list so that  
it can get a bit of vetting.

In the script, the value that I use for CMAKE_LIBRARY_PATH is this:

CMAKE_LIBRARY_PATH=/usr/local/ada-4.3/lib/gcc/powerpc-apple- 
darwin8/4.3.0/adalib:\
/Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libblas.dylib:\
/Developer/SDKs/MacOSX10.4u.sdk/usr/lib/liblapack.dylib
export CMAKE_LIBRARY_PATH

There's really no way to know this without asking around--this is  
kind of obscure stuff. The first path is to the GNAT library. The  
other two paths are to Apple's pre-installed numerical libraries,  
BLAS and LAPACK, which are necessary if you want to use the new  
vector-matrix capabilities of Ada 2005--otherwise, you can leave them  
off.

FWIW, yesterday I tried to install PLplot from MacPorts and it failed  
with an obscure MacPorts-related error. I've joined the MacPorts list  
to see what's going on. I think you mentioned that the MacPorts  
installer never finished--FWIW, some of these installations can take  
hours.

Finally (for the list), I have never succeeded in getting Ada to use  
Aquaterm to output PLplot stuff--the build always fails when I enable  
both Ada and Aquaterm. This is an issue that I have set aside to deal  
with other things. Some time back, Hazen Babcock suggested adding  
these lines to my bash installation file but I have not tried them:


export CMAKE_Ada_compiler=/usr/local/ada-4.3/bin/gcc
export GNAT_EXECUTABLE_BUILDER=/usr/local/ada-4.3/bin/gnatmake
export GNAT_LIB=/usr/local/ada-4.3/lib/gcc/powerpc-apple- 
darwin8/4.3.0/adalib/libgnat.dylib
export CMAKE_C_COMPILER=/usr/bin/gcc
