如何使用make保持文件同步?

synchronization makefile recursion file

ECHOCMD:=/bin/echo -e
SHELL := /bin/bash

GITIGNORE_SOURCE_PATH := ../.gitignore
GITIGNORE_DESTINE_PATH := ./setup/.gitignore

start_syncing: "${GITIGNORE_DESTINE_PATH}"
    printf '\n'

"${GITIGNORE_DESTINE_PATH}":
    cp -vr "${GITIGNORE_SOURCE_PATH}" ./setup/

"${GITIGNORE_DESTINE_PATH}" 每次我打电话的时候 make ,但它应该只在源文件 ../.gitignore 已修改。

这是建议我在评论中使用的make文件:

ECHOCMD:=/bin/echo -e
SHELL := /bin/bash

GITIGNORE_SOURCE_PATH := ../.gitignore
GITIGNORE_DESTINE_PATH := ./setup/.gitignore

start_syncing: "${GITIGNORE_DESTINE_PATH}"
    printf '\n'

${GITIGNORE_DESTINE_PATH}: ${GITIGNORE_SOURCE_PATH}
    cp -vr "${GITIGNORE_SOURCE_PATH}" ./setup/

运行它,它说:

$ ls -l ../.gitignore
-rwx---r-x+ 1 User None 488 Apr 27 23:23 ../.gitignore
$ ls -l ./setup/.gitignore
-rwx---r-x+ 1 User None 488 Apr 28 07:41 ./setup/.gitignore
$ make
make: *** No rule to make target '"./setup/.gitignore"', needed by 'start_syncing'.  Stop.

解决方案是从目标规则中删除双引号。如果名称上有空格,make除了手动转义空格的值外,别无选择 \


   ECHOCMD:=/bin/echo -e
SHELL := /bin/bash

GITIGNORE_SOURCE_PATH := ../.gitignore
GITIGNORE_DESTINE_PATH := ./setup/.gitignore

start_syncing: ${GITIGNORE_DESTINE_PATH}
    printf '\n'

${GITIGNORE_DESTINE_PATH}: ${GITIGNORE_SOURCE_PATH}
    cp -vr "${GITIGNORE_SOURCE_PATH}" ./setup/
