Question

我试图调试来自ChatScript开源chat-bot项目的gcc Makefile中的问题：

http://chatscript.sourceforge.net/

以下是我的相关版本号：

Ubuntu 14.04
make version 3.81
gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)

我似乎无法在当前工作目录旁边的另一个目录中找到源文件。如果我将源文件移动到当前目录，它可以正常工作，但如果我把文件放回旧目录，它会抱怨它无法找到它：

make: *** No rule to make target `privatesrc.cpp', needed by `all'.  Stop.

执行 make 时我所在的当前目录是SRC，即 Makefile 所在的目录。 privatesrc.cpp 驻留在一个兄弟目录中，可以通过此相对路径从SRC访问>

../ privatecode / privatesrc.cpp

为了调试这个问题，我想确切地看到每个make目标变量的文件是什么。我使用这两个SO帖子来尝试转储这些值：

How to print out a variable in makefile

Jim Nisby的回答。和

gnu make: list the values of all variables (or "macros") in a particular run

接受的答案。

我创建了这个名为 server_dry_run 的新制作目标，以实现此目的：

server_dry_run: DEFINES+= -DPRIVATE_CODE -DLOCKUSERFILE=1 -DEVSERVER=1 -DEVSERVER_FORK=1 -DDISCARDDATABASE=1
server_dry_run: PGLOAD= -pthread
server_dry_run: INCLUDEDIRS=-Ievserver
server_dry_run: all
server_dry_run: EXECUTABLE=../BINARIES/ChatScript
server_dry_run: CFLAGS=-c -Wall  -funsigned-char  -Wno-write-strings -Wno-char-subscripts -Wno-strict-aliasing 
# Uncomment this line if you want to filter out variables already defined.
# VARS_OLD := $(.VARIABLES)
CUR-DIR := $(shell pwd)
LOG-DIR := $(CUR-DIR)/make-logs
$(info INCLUDEDIRS="$(INCLUDEDIRS)")
$(foreach v,$(filter-out $(VARS_OLD) VARS_OLD,$(.VARIABLES)),$(info $(v) = $($(v))))

但是，INCLUDEDIRS始终显示为空：

INCLUDEDIRS=""

如何查看INCLUDEDIRS的值以便解决此问题？

以下是我的Makefile的全部内容。注意，我确实尝试删除了我在INCLUDEDIRS 分配的值附近添加的引号，但这没有帮助。另外一点数据。如果我做＆＃34;干净＆＃34;我收到错误＆＃34; rm：无法删除`../'：是一个目录＆＃34;，这似乎表明EXECUTABLE目标变量可能不是右
