Question

我在Eclipse C ++项目中向test添加了makefile.targets目标。现在，我希望它是作为我的Debug和Release构建配置的一部分构建的，所以我可以将我的单元测试作为正常构建过程的一部分运行。

我是如何做到这一点的，因为我无法修改自动生成的Debug/makefile和Release/makefile？

下面的伪代码有望回答关于目标添加的问题，另外还讨论了如何在makefile和源代码中使用变量。

我花了一天时间才使用网络资源来解决这个问题，特别是stackoverflow.com和eclipse.org论坛。 CDT的Eclipse文档在某些方面有点模糊。

// pseudo-code for Eclipse version Kepler
if ("Project.Properties.C/C++ Build.Generate Makefiles automatically" == true) {
  // when using the automatically generated makefiles,
  //   use the -include's in the generated Debug/makefile
  cp <your makefile init statements> $(ProjDirPath)/makefile.init
  cp <your makefile definitions>     $(ProjDirPath)/makefile.defs
  cp <your makefile targets>         $(ProjDirPath)/makefile.targets
} else {
  // when using a makefile that you maintain, alter your own makefile
  cp <your makefile targets>         <your makefile>
}
// Additionally, you may want to provide variables for use in the makefile 
//   commands, whether it's your own makefile or the generated one:
//    Note that:
//    - "Preferences.C/C++.Build.Build Variables" and
//      "Project.Properties.C/C++ Build.Build Variables" 
//       are *NOT directly available* to the makefile commands.
//    - "Preferences.C/C++.Build.Environment" variables and
//      "Project.Properties.C/C++ Build.Environment" variables
//      *ARE available* to the makefile commands.
//    - To make "Build Variables" available to the makefile and source files,
//      add an environment variable as shown below. Especially useful are the
//      built-in ones visible when "Show system variables" is checked.

// assign the build system variable "ProjDirPath" as a *user preference*
"Preferences.C/C++.Build.Environment".AddKeyValue("ProjDirPath",
                                                  "${ProjDirPath}"}

// assign the build system variable "ProjDirPath" as a *project property*
"Project.Properties.C/C++ Build.Environment".AddKeyValue("ProjDirPath",
                                                         ${ProjDirPath}")

示例“makefile.init”：

GREP := /bin/grep

示例“makefile.defs”：

ifndef ProjDirPath
  $(error "ProjDirPath" undefined as a "make variable" or "environment variable".)
endif

生成的makefile Debug / src / subdir.mk将依赖项提取到文件$ {ProjDirPath} / Debug / src / $ {ProjName} .d，但是您需要为初始生成依赖项添加额外的目标。您可以为：

添加目标

#include "automated_headers.h"

将目标添加到$ {ProjDirPath} /makefile.targets。

示例“makefile.targets”：

# targets to generate a header file
%/src/automated_headers.h: %/src/generate_headers.py $(external_library_info)
    @echo "Generating $@"
    %/src/generate_headers.py $(extrnal_library_info) $@

src/$(ProjName).o: $(ProjDirPath)/src/automated_headers.h

如果Make Target视图尚未打开，请将其打开。它有一个New Make Target按钮。

或者，在makefile中突出显示目标的名称，右键单击，然后转到Make Targets -> Create...。

编辑：我可能误解了你的问题。如果您希望构建目标，则在单击构建时，转到构建首选项并将其添加到那里。

如何在Eclipse中的构建配置中添加make目标？
