Re: Thick bindings to a C library and gnattest: suggestions?

[Maurizio Tomasi <ziotom78@gmail.com>]

Many thanks Simon, my problem was that I cannot decide "a priori" when to link statically and when dynamically, but you helped me in devise a solution:

project cfitsio is 
  for Externally_Built use "true";
  for Source_Files use ();
  for Library_Dir use external("CFITSIO_LIB_DIR");
  for Library_Name use "cfitsio";
  for Library_Kind use external("CFITSIO_LINKING");
end cfitsio; 


On my laptop running Linux Mint I have both the static and dynamic versions of CFITSIO, and now I am able to compile them using these commands:

CFITSIO_LIB_DIR=/usr/lib/x86_64-linux-gnu CFITSIO_LINKING=dynamic gprbuild test_driver.gpr

CFITSIO_LIB_DIR=/usr/lib/ CFITSIO_LINKING=static gprbuild test_driver.gpr

So, one of my problems is fully solved!
  Maurizio.
