I was able to compile PLplot with both Ada and Aquaterm. I have (or
at least I believe I have) installed Ada from www.macada.org using
the GnatPPC-4.3.dmg installer. I say I believe since I did this a
while ago and while I seem to have ada on my computer and I also have
this installer I've forgotten whether I actually used this installer
to install ada. Anyway.
The approach is to use the ada gcc *only* for compiling the ada
bindings. All my ada stuff is in /usr/local/ada-4.3, so I set:
CMAKE_Ada_compiler= /usr/local/ada-4.3/bin/gcc
GNAT_EXECUTABLE_BUILDER = /usr/local/ada-4.3/bin/gnatmake
GNAT_LIB = /usr/local/ada-4.3/lib/gcc/powerpc-apple-darwin8/4.3.0/
adalib/libgnat.dylib
(CMAKE_C_COMPILER is /usr/bin/gcc)
This will compile for me (OS-X 10.4, gcc 4.0.1), but the linking is
messed up in that the paths to the necessary ada libraries are not
correct:
examples/ada : otool -L x01a
x01a:
libplplotadad.0.0.0.dylib (compatibility version 0.0.0,
current version 0.0.0)
/Users/hbabcock/Documents/OpenSource/PLplot/plplot-CBS-1/src/
libplplotd.9.dylib (compatibility version 0.0.0, current version 0.0.0)
/usr/lib/libltdl.3.dylib (compatibility version 5.0.0,
current version 5.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 88.1.10)
/Users/hbabcock/Documents/OpenSource/PLplot/plplot-CBS-1/lib/
csa/libcsirocsa.0.dylib (compatibility version 0.0.0, current version
0.0.0)
/Users/hbabcock/Documents/OpenSource/PLplot/plplot-CBS-1/lib/
nn/libcsironn.0.dylib (compatibility version 0.0.0, current version
0.0.0)
/usr/local/lib/libqhull.5.dylib (compatibility version
6.0.0, current version 6.0.0)
libgnat-4.3.dylib (compatibility version 0.0.0, current
version 0.0.0)
/usr/local/lib/libgcc_s.1.dylib (compatibility version
1.0.0, current version 1.0.0)
Note that libplplotadad.0.0.0.dylib and libgnat-4.3.dylib do not have
any path information in front of them, unlike all the other
libraries. You can run the examples if you provide symlinks to these
libraries in the examples folder and I checked that you can in fact
use the aquaterm device with the ada examples.
Obviously it would better to have the correct path information with
the libraries.
