I am trying to compile a program with gnat, and am running into some
funny issues with naming.
I have two sets of files, with different naming conventions. One set,
a part of ORBexpress, follows the .ads/.adb convention. I don't have
the .adb files; instead I have the corresponding .ali and .o files.
The other set of files, part of software that I'm trying to get to
compile under gnat, follows the .1.ada/.2.ada convention.
I would like, insofar as possible, to (a) retain the .1.ada/.2.ada
convention for the files that follow that convention already [we have
thousands of files, and renaming them, even with gnatchop, would be
unpleasant]; and (b) use gnatmake for compilation [other developers I
work with would eventually like to use GPS for building files, and GPS
uses gnatmake].
I have tried creating two project files for this naming scenario;
these appear below. The first project file, ois.gpr, uses the
.ads/.adb convention. The second file, for my code, "withs" ois.gpr
and uses the .1.ada/.2.ada convention.
When I compile using gnatmake, I get the following error messages
(this is an excerpt; the full output of gnatmake appears below):
gnatmake: "corba.2.ada" not found
gnatmake: "corba-boa.2.ada" not found
gnatmake: "corba-command_line.2.ada" not found
gnatmake: "corba-orb.2.ada" not found
gnatmake: "corba-impl.2.ada" not found
gnatmake: "corba-impl-servant.2.ada" not found
gnatmake: "corba-request.2.ada" not found
gnatmake: "corba-serverrequest.2.ada" not found
gnatmake: "corba-stream.2.ada" not found
gnatmake: "corba-stream-time_optimized.2.ada" not found
gnatmake: "corba-object.2.ada" not found
gnatmake: "corba-object-helper.2.ada" not found
gnatmake: "corba-impl-server.2.ada" not found
It would appear that gnatmake is interpreting my project files to
mean: always use the .1.ada/.2.ada convention. When I "with" ois.gpr,
the second project file, gnatmake does not understand this to mean:
use the .ads/.adb convention for the ORBexpress files.
Is there any way to inform gnatmake to use the .1.ada/.2.ada
convention for my code, and the .ads/.adb convention for the
ORBexpress files?
I am using gnatpro 3.16a1.
Thanks,
Ben
