Question

我有一个项目目录结构如下：

Source-----------------
---Project1------------
-----------Project1_vA-
-----------Project1_vB-
---Project2------------
-----------Project2_vA-
-----------Project2_vB-
---Project3------------
-----------Project3_vA-

我正在尝试在所有子目录中为递归构建lib编写makefile：

DIRS    := $(dir $(wildcard $(LOCAL_PATH)/*/));
$(info $(DIRS))     

for item in $(DIRS); do \
    $(info sublib)      \
    $(info $(item))         \
    if [[ "$item" == "$LOCAL_PATH/glm/" ||      \
    "$item" == "$LOCAL_PATH/common/" ]]     \
    then                            \
        continue;                                                               \
    fi                                                                          \

    SUBDIRS := $(dir $(wildcard $(item)/*/))                            \
    $(info $(SUBDIRS))                                                          \
    for subitem in $(SUBDIRS); do                                       \
        include $(CLEAR_VARS)                                                   \
        $(info $(subitem))                                                      \
        LOCAL_MODULE            := $(subitem)                                           \                                       \
        LOCAL_CFLAGS            := -g -fexceptions                              \
        LOCAL_ARM_MODE          := arm                                          \
        LOCAL_SRC_FILES         := $(subitem)/*.cpp                             \
                                $(subitem)/main.cpp                             \
        LOCAL_SHARED_LIBRARIES  := common                                           \
        LOCAL_LDLIBS            := -llog -lGLESv2   \
        include $(BUILD_SHARED_LIBRARY)                                         \
    done;                                                                       \
done;

但是，循环块中的错误 - $(info $(item)) - 显示空格。

$(info $(DIRS)) - 显示"Source/Project1/ Source/Project2/ Source/Project3/;"

请帮助。

使用find怎么样？

DIRS := `find . -type d`
PROJECT_DIRS := $(filter ...,$(DIRS))
NON_PROJECT_DIRS := $(filter-out ...,$(DIRS))

.PHONY: $(DIRS)

$(PROJECT_DIRS): $(NON_PROJECT_DIRS)
    ... rules for making projects ...

$(NON_PROJECT_DIRS):
    ... rules for making sub dirs ...

递归搜索子目录
