AWS for Ada的安装问题 [英] Installation issue with AWS for Ada

问题描述

今晚我第一次在Macbook上安装了Ada和AWS。

I installed Ada and AWS on a Macbook for the first time tonight.

安装似乎一切都成功，但是我感觉到AWS并没有t安装到正确的目录。

Everything seemed successful with the installation, but I'm getting the feeling that AWS didn't install to the right directory.

GNAT位于/ usr / local / gnat中。

GNAT is in /usr/local/gnat.

AWS Makefile .conf表示，

The AWS makefile.conf said,

AWS will be installed under $(prefix). Update this variable to point to
the install directory. By default, it is set to the current GNAT root
directory to have AWS project files automatically available.

所以我没有更改目标。

但是当我尝试从系统上除AWS demos文件夹之外的任何地方编译hello_world时，都会出现此错误：

But when I try to compile hello_world from anywhere on the system except the AWS demos folder, I get this error:

~/projects/ada:gnatmake hello.adb
gcc -c hello.adb
hello.adb:1:06: file "aws.ads" not found
hello.adb:2:06: file "aws.ads" not found
hello.adb:3:06: file "aws.ads" not found
hello.adb:4:06: file "aws.ads" not found
gnatmake: "hello.adb" compilation error

如何确保已安装AWS

How can I make sure AWS was installed properly, or move it if it wasn't?

推荐答案

答案（嗯，更多的是对那些知道的人的提示） ）的意思是使AWS项目文件自动可用。

The answer (well, more of a hint to those in the know) lies in the words "to have AWS project files automatically available".

在GNAT上下文中，项目文件表示类型为的文件.gpr 告诉构建器（ gnatmake 或 gprbuild ）在哪里找到源文件，如何编译em，以及在哪里可以找到此项目所依赖的任何库。

In the GNAT context, "project file" means a file of type .gpr which tells the builder (gnatmake or gprbuild) where to find the source files, how to compile them, and where to find any libraries that "this" project depends on.

创建 hello.gpr ：

with "aws";
project Hello is
   for Main use ("hello.adb");
end Hello;

（非常最小）然后

with AWS;
with Ada.Text_IO;
procedure Hello is
begin
   Ada.Text_IO.Put_Line ("AWS version is " & AWS.Version);
end Hello;

与

gprbuild -P hello.gpr

输出

AWS version is 2.10.0w

在 gprbuild 和 gnatmake （ gnatmake 被 gprbuild 取代）；在您安装的GNAT中可能有位于 $ {prefix} / share / doc （子目录）中的信息。

There is on-line information on gprbuild and gnatmake (gnatmake has been superseded by gprbuild); there is probably information in your installed GNAT at (subdirectories of) ${prefix}/share/doc.
