How do I add a make target to a build configuration in Eclipse?
提问by Josh Glover
I've added a testtarget to makefile.targetsin an Eclipse C++ project. Now, I want it to be built as part of my Debug and Release build configurations so I can have my unit tests run as part of the normal build process.
我在 Eclipse C++ 项目中添加了一个test目标makefile.targets。现在，我希望将它构建为我的调试和发布构建配置的一部分，以便我可以将我的单元测试作为正常构建过程的一部分运行。
How do I do this, given that I cannot edit the auto-generated Debug/makefileand Release/makefile?
鉴于我无法编辑自动生成的Debug/makefile和，我该怎么做Release/makefile？

The pseudo-code below hopefully answers the question about target addition, and additionally addresses how to use variables in the makefile and source code.
下面的伪代码有望回答有关目标添加的问题，并另外解决了如何在 makefile 和源代码中使用变量。
It took me a day to figure this out using web resources, especially stackoverflow.com and eclipse.org forums. The Eclipse documentation for CDT is a bit vague on some points.
我花了一天的时间使用网络资源，尤其是 stackoverflow.com 和 eclipse.org 论坛来解决这个问题。CDT 的 Eclipse 文档在某些方面有点含糊。
// 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}")
An example "makefile.init":
一个例子“makefile.init”：
GREP := /bin/grep
An example "makefile.defs":
一个例子“makefile.defs”：
ifndef ProjDirPath
$(error "ProjDirPath" undefined as a "make variable" or "environment variable".)
endif
The generated makefile Debug/src/subdir.mk extracts dependencies into the file ${ProjDirPath}/Debug/src/${ProjName}.d, but you need to add an extra target for initial generation of a dependency. You could add a target for an:
生成的makefile Debug/src/subdir.mk 将依赖提取到文件${ProjDirPath}/Debug/src/${ProjName}.d 中，但是您需要为初始生成依赖添加一个额外的目标。您可以为以下对象添加目标：
#include "automated_headers.h"
by adding targets to ${ProjDirPath}/makefile.targets.
通过向 ${ProjDirPath}/makefile.targets 添加目标。
An example "makefile.targets":
一个例子“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

Open the Make Targetview if it's not already open. It has a New Make Targetbutton.
打开Make Target查看，如果它不是已经打开。它有一个New Make Target按钮。
Alternatively, highlight the name of the target in the makefile, right click, and go to Make Targets -> Create....
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...。
Edit: I may have misunderstood your question. If you want the target to be built, when you click build, go to the build preferences and add it there.
编辑：我可能误解了你的问题。如果您希望构建目标，当您单击构建时，转到构建首选项并将其添加到那里。
