Bash 使用GNU Make递归复制文件

bash makefile

Bash 使用GNU Make递归复制文件,bash,makefile,gnu-make,Bash,Makefile,Gnu Make,我得到了一个存储我的项目资产的目录，比如： +-- assets | +-- styles | | +-- child | | | +-- child.css | | +-- main.css | +-- font.ttf | +-- image.png 如您所见，它们是几种文件类型（这只是一个示例，可能有更多类型），并且树的深度可能会有所不同 如何将所有这些文件复制到单个（平面）位置？大概是这样的： +-- assets | +-- child.c

我得到了一个存储我的项目资产的目录，比如：

+-- assets
|   +-- styles
|   |   +-- child
|   |   |   +-- child.css
|   |   +-- main.css
|   +-- font.ttf
|   +-- image.png
如您所见，它们是几种文件类型（这只是一个示例，可能有更多类型），并且树的深度可能会有所不同

如何将所有这些文件复制到单个（平面）位置？大概是这样的：

+-- assets
|   +-- child.css
|   +-- font.ttf
|   +-- image.png
|   +-- main.css
我尝试使用模式规则，但我对GNU Make非常陌生，所以似乎什么都不管用

我使用Bash globstar功能获得了源文件的递归列表，并通过Make的字符串操作函数对其进行了修改：

BR_ASSETS := /home/user/project/assets/
BR_APP_ASSETS := /home/user/project/build/assets/

SOURCES := $(shell ls $(BR_ASSETS)**/*.*)
TARGETS := $(addprefix $(BR_APP_ASSETS),$(notdir $(SOURCES)))
接下来呢

非常感谢

all:
.PHONY: all

BR_ASSETS := /home/user/project/assets/
BR_APP_ASSETS := /home/user/project/build/assets/

SOURCES := $(shell find $(BR_ASSETS) -type f)
$(info SOURCES=$(SOURCES))
TARGETS := $(addprefix $(BR_APP_ASSETS),$(notdir $(SOURCES)))

# Generate rules to map sources into targets
$(foreach s,$(SOURCES),$(foreach t,$(filter %$(notdir $s),$(TARGETS)),$(info New rule: $t: $s)$(eval $t: $s)))

# All targets have the same recipe.
$(TARGETS):; $(if $(wildcard $(@D)),,mkdir -p $(@D) &&) cp $^ $@

all: $(TARGETS)
clean:; rm -rf $(BR_APP_ASSETS)
.PHONY: clean
