[gps-users] GPS and ADA_OBJECT_PATH variables

[Mathieu Dubois]

Hello,

For my project I need to link to the APQ library (this library allow an 
Ada program to connect to a  database).
As required by the installation manual I have set the ADA_INCLUDE_PATH 
and ADA_OBJECTS_PATH to the place where APQ is installed:
$ echo $ADA_OBJECTS_PATH
/home/duboism/adalib
$ echo $ADA_OBJECTS_PATH
/home/duboism/adalib
The variables are set in ~/.bashrc (I work under Ubuntu 10.04).

I can compile and link my program from the command line without problem.

But when I try to compile it from GPS the link fails (note that the 
compilation works so APQ.ads is found):
gnatlink 
/home/duboism/Documents/These/Code/manips/rvg/manips/COLD/Article1/objs/test_bayesian_filtering.ali 
-o 
/home/duboism/Documents/These/Code/manips/rvg/manips/COLD/Article1/test_bayesian_filtering
/usr/bin/ld: cannot find -lapq
collect2: ld returned 1 exit status
gnatlink: error when calling /usr/bin/gcc-4.4
gnatmake: *** link failed.

There are 2 obvious solutions to that:
  1) edit the project file to add the right switch to gnatlink
  2) launch GPS from a shell (where ADA_INCLUDE_PATH and 
ADA_OBJECTS_PATH are set)

I don't want to use solution 1 because then I would need to change the 
project file for use on another computer (eg with a different login).

Solution 2 seems reasonable but I wonder why GPS doesn't take into 
account the ADA_OBJECTS_PATH variable. Is there any way to do that?

Thanks in advance,
Mathieu
