Ada:gnat gprbuild如何在库中链接？

Question

在我正在研究的这个多语言GPRBuild项目中,我有一些c ++库文件(*.a)我需要链接到我的可执行文件.是否有一个gpr属性告诉它将-l -L开关传递给链接器的链接是什么？

Answer 1

在主项目文件中,

package Linker is
   for Default_Switches ("Ada") use ("-L/where/ever", "-lbar");
end Linker;

Answer 2

甚至更好:

Project my_library is
  For externally_built use "true";
  For library_dir use "/where/ever";
  For library_name use "mylibname";
  For source_dirs use (); -- no sources.
  For library_kind use "static";
  -- if it is a static lib .a

  -- for library_kind use "dynamic";
  -- if it is an so.
End my_library;

并在应用程序项目中.用"my_library.gpr";
