Hmm, adding C files into the list of sources should suffice. For example,
the following works for me:
------- mixed.gpr
project Mixed is
for Languages use ("Ada", "C");
for Source_Dirs use (".");
for Source_Files use ("main.adb", "c.c");
for Main use ("main.adb");
end Mixed;
------ main.adb
with Ada.Text_IO; use Ada.Text_IO;
with Interfaces.C; use Interfaces.C;
procedure Main is
function C return Int;
pragma Import (C, C);
begin
Put_Line ("Value:" & Int'Image (C));
end Main;
------ c.c
int c (void)
{
return 123;
}
----------------------------------------------
This should compile under GPS and print
Value: 123
