My new gpr file, given below, has been generated by the GPS 2.1.0
project wizard.
I'll not copy here the build output since it's pretty long but mainly it
shows :
- that all Ada files are compiled correctly
- no C file are compiled (nor library built)
- bind works without error
- link fails with 'undefined reference to ...' messages related to all
imported C functions that should have been compiled previoulsy.

In fact, my question was more general, since it happens not only for
this project, but for all I try to build of the same kind (i.e.
containing Ada + C sources) :
1) isn't GPS supposed to work as I remember ('automatically' compile Ada
files with gnatmake, C files with gcc, bind and link it all)?
2) if it is, what are the topics to select in the project wizard to
achieve it (the only relevant I found are language and source
directories selection)
Thanks in advance
