【已解决】Makefile自定义函数调用出错：unterminated call to function `notdir’: missing `)’. Stop

折腾：

期间，Makefile中尝试自己写函数：

<code>define getCurrentDirAndDirName
# get current folder name
  # support call makefile from anywhere, not only from current path of makefile located
  # MAKEFILE_PATH := $(abspath $(lastword $(MAKEFILE_LIST)))
  # CURRENT_DIR_WITH_SLASH := $(notdir $(patsubst %/,%,$(MAKEFILE_DIR))
  MAKEFILE_LIST_LASTWORD = $(lastword $(MAKEFILE_LIST))
  MAKEFILE_PATH := $(abspath $(MAKEFILE_LIST_LASTWORD))
  MAKEFILE_DIR := $(dir $(MAKEFILE_PATH))
  MAKEFILE_DIR_PATSUBST := $(patsubst %/,%,$(MAKEFILE_DIR))
  MAKEFILE_DIR_NOSLASH = $(MAKEFILE_DIR_PATSUBST)
  CURRENT_DIR_WITH_SLASH = $(MAKEFILE_DIR)
  CURRENT_DIR = $(MAKEFILE_DIR_NOSLASH)
  CURRENT_DIR_NAME := $(notdir $(MAKEFILE_DIR_PATSUBST))
  $(1) := $$(CURRENT_DIR_NAME)
  $(2) := $$(CURRENT_DIR)
endef

$(eval $(call getCurrentDirAndDirName, CURRENT_DIR_NAME, CURRENT_DIR))
echo "CURRENT_DIR_NAME="$(CURRENT_DIR_NAME)
$(info "CURRENT_DIR="${CURRENT_DIR})
</code>

结果调用出错：

<code>../Makefile_common:34: *** unterminated call to function `notdir': missing `)'.  Stop.
</code>

然后去加上echo：

<code>  MAKEFILE_LIST_LASTWORD = $(lastword $(MAKEFILE_LIST))
  echo MAKEFILE_LIST_LASTWORD=$(MAKEFILE_LIST_LASTWORD)

  MAKEFILE_PATH := $(abspath $(MAKEFILE_LIST_LASTWORD))
  echo MAKEFILE_PATH=$(MAKEFILE_PATH)

  MAKEFILE_DIR := $(dir $(MAKEFILE_PATH))
</code>

都无法打印出信息。

难道是自定义函数中，多加了tab，没有开头？

改为：

<code>define getCurrentDirAndDirName
# get current folder name
# support call makefile from anywhere, not only from current path of makefile located
# MAKEFILE_PATH := $(abspath $(lastword $(MAKEFILE_LIST)))
# CURRENT_DIR_WITH_SLASH := $(notdir $(patsubst %/,%,$(MAKEFILE_DIR))
MAKEFILE_LIST_LASTWORD = $(lastword $(MAKEFILE_LIST))
echo MAKEFILE_LIST_LASTWORD=$(MAKEFILE_LIST_LASTWORD)

MAKEFILE_PATH := $(abspath $(MAKEFILE_LIST_LASTWORD))
echo MAKEFILE_PATH=$(MAKEFILE_PATH)

MAKEFILE_DIR := $(dir $(MAKEFILE_PATH))
MAKEFILE_DIR_PATSUBST := $(patsubst %/,%,$(MAKEFILE_DIR))
MAKEFILE_DIR_NOSLASH = $(MAKEFILE_DIR_PATSUBST)
CURRENT_DIR_WITH_SLASH = $(MAKEFILE_DIR)
CURRENT_DIR = $(MAKEFILE_DIR_NOSLASH)
CURRENT_DIR_NAME := $(notdir $(MAKEFILE_DIR_PATSUBST))
$(1) := $$(CURRENT_DIR_NAME)
$(2) := $$(CURRENT_DIR)
endef
</code>

结果：问题依旧。

把：

<code>$(1) := $$(CURRENT_DIR_NAME)
$(2) := $$(CURRENT_DIR)
</code>

改为：

<code>$(1) := $(CURRENT_DIR_NAME)
$(2) := $(CURRENT_DIR)
</code>

结果：

问题依旧。

才注意到：

define的函数中，都是 $1，而不是$(1)去访问参数的。

所以改为：

<code>CURRENT_DIR_NAME := $(notdir $(MAKEFILE_DIR_PATSUBST))
$1 := $(CURRENT_DIR_NAME)
$2 := $(CURRENT_DIR)
</code>

结果：

问题依旧。

看起来像是：notdir的问题？

makefile notdir

GNU make: File Name Functions

makefile中wildcard notdir patsubst的简单介绍 – CSDN博客

“$(notdir names…)

Extracts all but the directory-part of each file name in names. If the file name contains no slash, it is left unchanged. Otherwise, everything through the last slash is removed from it.

A file name that ends with a slash becomes an empty string. This is unfortunate, because it means that the result does not always have the same number of whitespace-separated file names as the argument had; but we do not see any other valid alternative.

For example,

$(notdir src/foo.c hacks)

produces the result ‘foo.c hacks’.
”

暂时注释掉notdir试试：

<code>CURRENT_DIR = $(MAKEFILE_DIR_NOSLASH)
# CURRENT_DIR_NAME := $(notdir $(MAKEFILE_DIR_PATSUBST))
# $1 := $(CURRENT_DIR_NAME)
$2 := $(CURRENT_DIR)
endef
</code>

结果：问题依旧。

把34行的，define的函数开始的注释移到函数外面：

<code># get current folder name
# support call makefile from anywhere, not only from current path of makefile located
# MAKEFILE_PATH := $(abspath $(lastword $(MAKEFILE_LIST)))
# CURRENT_DIR_WITH_SLASH := $(notdir $(patsubst %/,%,$(MAKEFILE_DIR))
define getCurrentDirAndDirName
MAKEFILE_LIST_LASTWORD = $(lastword $(MAKEFILE_LIST))
# echo MAKEFILE_LIST_LASTWORD=$(MAKEFILE_LIST_LASTWORD)
$(info "MAKEFILE_LIST_LASTWORD="${MAKEFILE_LIST_LASTWORD})

MAKEFILE_PATH := $(abspath $(MAKEFILE_LIST_LASTWORD))
echo MAKEFILE_PATH=$(MAKEFILE_PATH)

MAKEFILE_DIR := $(dir $(MAKEFILE_PATH))
MAKEFILE_DIR_PATSUBST := $(patsubst %/,%,$(MAKEFILE_DIR))
MAKEFILE_DIR_NOSLASH = $(MAKEFILE_DIR_PATSUBST)
CURRENT_DIR_WITH_SLASH = $(MAKEFILE_DIR)
CURRENT_DIR = $(MAKEFILE_DIR_NOSLASH)
# CURRENT_DIR_NAME := $(notdir $(MAKEFILE_DIR_PATSUBST))
# $1 := $(CURRENT_DIR_NAME)
$2 := $(CURRENT_DIR)
endef
</code>

结果：

可以正常运行了。。。

在此期间出现：

【已解决】Makefile中define自定义函数中打印输出没效果

【总结】

此处的：

<code>define getCurrentDirAndDirName
# get current folder name
...
endef
</code>

的Makefile中出错：

unterminated call to function `notdir’: missing `)’. Stop

的原因是：

define的开始不能包含# xxx的注释

解决办法是：

把# xxx移动到define 自定义函数外部：

<code># get current folder name
# support call makefile from anywhere, not only from current path of makefile located
# MAKEFILE_PATH := $(abspath $(lastword $(MAKEFILE_LIST)))
# CURRENT_DIR_WITH_SLASH := $(notdir $(patsubst %/,%,$(MAKEFILE_DIR))
define getCurrentDirAndDirName
MAKEFILE_LIST_LASTWORD = $(lastword $(MAKEFILE_LIST))
# echo MAKEFILE_LIST_LASTWORD=${MAKEFILE_LIST_LASTWORD}
# $(info "MAKEFILE_LIST_LASTWORD="${MAKEFILE_LIST_LASTWORD})
# print MAKEFILE_LIST_LASTWORD

xxx
endef
</code>

即可。
