使用 Jobs (Multicore) 标志导致 Makefile 编译失败
Using Jobs (Multicore) Flag Causes Makefile Compilation to Fail
更新：感谢大家的帮助，tripleee的递归建议成功了
flash: clean
sudo $(make) -j8 default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase
nrfjprog -f nrf52 --reset
我注意到有时当我对我的代码进行小改动并使用 make 重新编译时，我的代码会失败。一个快速解决这个问题的方法是做一个干净的构建（删除我的构建目录并重建）。如果我并行化 make 过程 (-j8)，它会在 10 秒内完成编译，所以这是一个可以接受的快速解决方案。
为了自动执行清理过程，我设置了
clean:
ifeq ($(UNAME), Linux)
sudo rm -rf _build
else
@echo os not supported
endif
flash: clean default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase
nrfjprog -f nrf52 --reset
几天前我使用它时它起作用了，但现在当我使用 -j 标签和 >1 个处理器进行编译时它失败了。

这几乎肯定是不对的：
flash: clean default
这告诉 make clean 和 default 目标都需要在调用 flash 目标的配方之前完成。
但是，它完全没有提及 clean 和 default 目标本身之间的任何关系。既然那是真的，如果您使用 -j 选项调用它，make 将可以自由地并行 运行 两个目标（及其先决条件）的配方。
您的 clean 目标与其他构建目标并行 运行 不太可能可靠地工作。
预计到达时间
只有一种方法可以告诉 make 在启动另一个目标之前必须构建一个目标，那就是定义先决条件关系。所以如果你想要求 clean 必须在 default 之前完成，告诉 make 的唯一方法是使用：
default: clean
但是您可能不想这样做，因为这意味着每次您 运行 default 目标时，它将首先 运行 clean 目标.
您可以执行一些复杂的操作，但最简单的操作是使用递归 make 调用。那看起来像这样：
flash: clean
$(MAKE) default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase
nrfjprog -f nrf52 --reset
这首先在 flash 的配方之前强制 clean 到 运行，然后 flash 配方中的第一行调用构建 default目标。
更新：感谢大家的帮助，tripleee的递归建议成功了
flash: clean
sudo $(make) -j8 default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase
nrfjprog -f nrf52 --reset
我注意到有时当我对我的代码进行小改动并使用 make 重新编译时，我的代码会失败。一个快速解决这个问题的方法是做一个干净的构建（删除我的构建目录并重建）。如果我并行化 make 过程 (-j8)，它会在 10 秒内完成编译，所以这是一个可以接受的快速解决方案。
为了自动执行清理过程，我设置了
clean:
ifeq ($(UNAME), Linux)
sudo rm -rf _build
else
@echo os not supported
endif
flash: clean default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase
nrfjprog -f nrf52 --reset
几天前我使用它时它起作用了，但现在当我使用 -j 标签和 >1 个处理器进行编译时它失败了。

这几乎肯定是不对的：
flash: clean default
这告诉 make clean 和 default 目标都需要在调用 flash 目标的配方之前完成。
但是，它完全没有提及 clean 和 default 目标本身之间的任何关系。既然那是真的，如果您使用 -j 选项调用它，make 将可以自由地并行 运行 两个目标（及其先决条件）的配方。
您的 clean 目标与其他构建目标并行 运行 不太可能可靠地工作。
预计到达时间
只有一种方法可以告诉 make 在启动另一个目标之前必须构建一个目标，那就是定义先决条件关系。所以如果你想要求 clean 必须在 default 之前完成，告诉 make 的唯一方法是使用：
default: clean
但是您可能不想这样做，因为这意味着每次您 运行 default 目标时，它将首先 运行 clean 目标.
您可以执行一些复杂的操作，但最简单的操作是使用递归 make 调用。那看起来像这样：
flash: clean
$(MAKE) default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52832_xxaa.hex --sectorerase
nrfjprog -f nrf52 --reset
这首先在 flash 的配方之前强制 clean 到 运行，然后 flash 配方中的第一行调用构建 default目标。
