ADA图书馆GPR项目:为什么gprinstall不工作?

在玩了之后 Install 包选项和命令行,我终于实现了一些事情:

1. 这个 for Mode use "dev" gpr文件中的选项使 gprinstall 工具完全麻木。起初,我在adacore上找不到可靠的文档( http://docs.adacore.com/gprbuild-docs/html/gprbuild_ug/gnat_project_manager.html#installing-a-library-with-project-files ) 但这里有点清楚 https://docs.adacore.com/gprbuild-docs/html/gprbuild_ug/companion_tools.html#installing-with-gprinstall
2. gprinstall默认复制所有源( -a 默认激活)。您可以使用命令行开关更改它 -m .
3. 中指示的文件夹 Install_Root := "../INSTALL_BUILDS/"; 从gnat bin路径开始计算(由于环境变量: PATH=E:\DEV\GNAT\2017\bin;... )
4. 由安装包选项诱导的文件夹层次结构适用于多个gprinstall传递。我在下面的评论部分指出了生产的GPR选项。

使用这些GPRS:

library project LibA is
   for Source_Dirs       use ("src") & InterfaceA.Interface_Files;
   for Object_Dir        use "obj";
   for Library_Name      use project'Name;
   for Library_Dir       use "Library";
   for Library_Ali_Dir   use "Library_Ali";
   for Library_Src_Dir   use "Public_Interfaces";
   for Library_Interface use (InterfaceA.Interface_Name);
   for Library_Kind      use "static";

   package Install extends Production_Options.Install is
      for Prefix use Production_Options.Install.Install_Root_Libs;

      -- makes gprinstall silent and numb in --dry-run mode ?!
      -- for Mode use "dev";
      for Side_Debug use "true";
   end Install;
   -- various renames of Productions_Options
end LibA;

project Production_Options is
   package Install is
      Install_Root := project'Project_Dir & "../INSTALL_BUILDS/";
      Install_Exe  := "EXECUTABLES/";
      Install_Libs := "LIBS/";
      Install_Root_Exe  := Install_Root & Install_Exe;
      Install_Root_Libs := Install_Root & Install_Libs;
      for Prefix         use Install_Root;
      for Exec_Subdir    use "EXE";
      for Lib_Subdir     use "BIN";
      for Ali_Subdir     use "ALI";
      for Sources_Subdir use "SRC";
      for Project_Subdir use "GPR";
      --
      -- |                      with my settings: |_INSTALL_BUILDS
      -- |_Prefix                                   |_LIBS
      --      |_Exec_Subdir                           |_Exec_Subdir
      --        |_liba                                  |_liba would contain exe if it was an exe project
      --      |_Lib_Subdir                            |_Lib_Subdir
      --         |_liba                                 |_liba contains the .a file
      --      |_Ali_Subdir                            |_Ali_Subdir
      --        |_liba                                  |_liba contains the ali files
      --      |_Sources_Subdir                        |_Sources_Subdir
      --         |_liba                                 |_liba contains the src files
   end Install;
end Production_Options;

命令 gprinstall -m --dry-run -p -f -P LibA.gpr 现在工作正常。

以下是您可能获得的输出:

E:\DEV\Projets\Ada\LibA>gprinstall -d -m -p -f -P LibA.gpr
Install project LibA
cp E:\DEV\Projets\Ada\InterfaceA\src\InterfaceA.ads E:\DEV\GNAT\INSTALL_BUILDS\LIBS\SRC\liba\interfacea.ads
cp E:\DEV\Projets\Ada\LibA\Library_Ali\interfacea.ali E:\DEV\GNAT\INSTALL_BUILDS\LIBS\ALI\liba\interfacea.ali
cp E:\DEV\Projets\Ada\LibA\Library\libliba.a E:\DEV\GNAT\INSTALL_BUILDS\LIBS\BIN\liba\libliba.a

Project E:\DEV\GNAT\INSTALL_BUILDS\LIBS\GPR\liba\LibA.gpr would be installed
