Question

首先让我描述一下我的文件夹结构

| SourceCode folder
| | Build folder
| | | makefile 
| | | buildrules.mak

| | Integration_Tests folder
| | | Subsystem_1_Test folder
| | | | buildfiles folder
| | | | test.cpp
| | | | makefile

| | Subsystem_1 folder
| | | buildfiles folder
| | | source1.cpp
| | | source2.cpp
| | | source3.cpp
| | | makefile

| | Subsystem_2 folder
| | | buildfiles folder
| | | source4.cpp
| | | source5.cpp
| | | source6.cpp
| | | makefile

因此，build文件夹中的makefile将通过调用较低的makefile来构建所有子系统和集成测试。每个子系统都会创建一个可执行文件，每个子系buildfiles文件夹存储依赖项文件，目标文件和最终可执行代码。这些都是由makefile构建的。

集成测试使用测试下的子系统代码构建，并构建子系统，但在子系统文件夹中本地。每个子系统集成测试的makefile使用vpath来设置子系统文件夹的路径。即，对于子系统1测试，vpath是：

vpath = ../../Subsystem_1

我没有确切的代码在我面前，但编译行基本上定义如下，它位于buildrules.mak中并被所有makefile使用

./buildfiles/%.o : %.cpp
     compile the code

所以我看到的问题是当我构建集成测试时，它应该在技术上构建和链接正常，它似乎是在Subsystem_1 / buildfiles文件夹中找到目标文件并说子系统代码是构建的并且只构建测试的.cpp。

这是一个错误，因为测试已经定义了构建定义，并且需要再次构建子系统以进行正确的测试。

现在如果没有构建子系统1，即没有目标文件，那么我的集成测试将按照预期将目标文件放在本地集成测试buildfiles文件夹中来构建文件。

我相信这是因为在集成测试make文件中设置了vpath。它似乎在subsystem_1文件夹中搜索目标文件，并且不幸地找到它们。

如果我正在构建Subsystem_1文件夹并且测试已经构建，我没有看到任何问题，这可能是因为Subsystem_1中的vpath没有测试路径，不应该这样。

我似乎无法弄清楚如何解决这个本质上是文件路径概率的问题。看来我需要更具体地说明我需要在编译行中匹配哪个buildfiles文件夹，但我没有路径。

我无法使用$（CURDIR）因为这是一条绝对路径而且我被告知我必须使用相对路径。我猜路径有空格和括号有问题。我可能在使用它之前逃脱它们，但有人告诉我必须用相对路径做所有事情。

我在buildrules.mak中有一个变量，它是执行make到buildrules.mak的目录的相对路径。这是通过以下方式完成的：

BUILD_FOLDER_PATH := $(dir $(word $(words $(MAKEFILE_LIST)),$(MAKEFILE_LIST)))

有没有办法解析$（CURDIR）让我到像sourcecod这样的公共文件夹？然后可以做类似的事情：

$(BUILD_FOLDER_PATH)/../[path extracted from $(CURDIR)]/buildfiles

因此，如果$（CURDIR）是c：/ a / b / sourcecode / Integration_Tests / Subsystem_Test，那么我可以从中提取“/ Integration_Tests / Subsystem_Test”以进入上述路径。

如果还有其他方法可以做到这一点，我也愿意接受建议。

谢谢！

“围绕源树路径到达各种文件夹”正是问题所在。

我建议您尝试在buildrules.mak添加一行。在两个include语句之后，靠近顶部，放入
