我不确定为什么，但突然当我打电话给我的Makefile时，它开始删除所有的目标文件！它不是在删除之前，而是在运行Makefile后最近，这是
我在控制台窗口中获得的内容：
rm OMXCore.o JPEG.o OMXComponent.o Logger.o hello_jpeg.o Locker.o Event.o
<任何想法为什么它是删除我的对象文件？以及如何阻止Make删除它？
更奇怪的是，它并没有在昨天删除它，而且今天一切都开始了，没有我做任何升级或做任何改变！
现在，当我在其中一个src文件中做一个小改动时，现在我必须等待很长时间才能重新生成所有其他目标文件，这不是必需的，它会减慢我的速度。
我确定我在正确的目录中，
我甚至给了make一个完整的路径，以防万一它正在拾取一个不同的Makefile
make -f / my_full_path / Makefile
Makefile运行时，我在另一个终端上执行ls我注意到我正在积累目标文件，如下所示：
-rw-rw-r-- 1 pi pi 1170 Mar 3 19:28 Makefile
-rw-r - r-- 1 pi pi 482052 Mar 3 19:30 OMXComponent.o
-rw-r - r - 1 pi pi 19984 Mar 3 19:30 Event.o
-rw-r - r-- 1 pi pi 14688 Mar 3 19:30 hello_jpeg.o
-rw-r - r - 1 pi pi 162260 Mar 3 19:31 JPEG.o
-rw-r - r-- 1 pi pi 215492 Mar 3 19:31 OMXCore.o
-rw-r - r-- 1 pi pi 76384 Mar 3 19:31 Locker.o
-rw-r - r - 1 pi pi 0 Mar 3 19:31 Logger.o
但是突然之间，所有的目标文件都被删除了！ !!
这里是Makefile命令的输出：

解决方案
文件正在被删除，因为 make 认为它们是中间。当 make 形成一系列规则来生成先决条件时，它会将由中间链创建的所有文件视为中间，然后在创建目标时将其删除。请参阅GNU make手册中的链接规则。
在你的情况中，你可以通过两种方法来防止这种情况：摆脱％。bin 规则，这似乎是错误的，因为它所有 .bin 文件都依赖于固定的目标文件列表，并将其替换为
$（BIN）：$（OBJS）
＃如前
或将目标文件标记为次要：
.SECONDARY：$（OBJS）
Here is the Makefile code:

I am not sure why, but suddenly when I am calling my Makefile, it started deleting all the object files !!! It was not deleting before, but lately after running the Makefile, this is what I get in the console window:
rm OMXCore.o JPEG.o OMXComponent.o Logger.o hello_jpeg.o Locker.o Event.o
Any idea why it is removing my object files? and how to stop Make from deleting it? What is even more strange is that it was not deleting it yesterday, and it all started today, without me doing any upgrades or making any changes!!! Now when I make a small change in one of my src files, now I have to wait a long time for all the other object files to rebuilt again, which is not necessary and it slows me down.
I am making sure that I am in the correct directory, I even gave "make" a complete path, in case if it is picking up a different Makefile
make -f /my_full_path/Makefile
While Makefile was running, I was doing "ls" in a different terminal, and I noticed that I am correctly accumulating object files, as below:
-rw-rw-r-- 1 pi pi 1170 Mar 3 19:28 Makefile
-rw-r--r-- 1 pi pi 482052 Mar 3 19:30 OMXComponent.o
-rw-r--r-- 1 pi pi 19984 Mar 3 19:30 Event.o
-rw-r--r-- 1 pi pi 14688 Mar 3 19:30 hello_jpeg.o
-rw-r--r-- 1 pi pi 162260 Mar 3 19:31 JPEG.o
-rw-r--r-- 1 pi pi 215492 Mar 3 19:31 OMXCore.o
-rw-r--r-- 1 pi pi 76384 Mar 3 19:31 Locker.o
-rw-r--r-- 1 pi pi 0 Mar 3 19:31 Logger.o
But all of a sudden, after everything is built, all the object files get removed !!!
And, here is the output of the Makefile command:
pi@raspberrypi /opt/vc/src/hello_pi/hello_jpeg_v2 $ make -f /opt/vc/src/hello_pi/hello_jpeg_v2/Makefile

解决方案
The files are being removed because make considers them "intermediate". When make forms a chain of rules to produce a prerequisite, it treats all files created by the intermediate chains as "intermediate" and removes then when the target is created. See Chained Rules in the manual for GNU make.
In your case, you can prevent this in two ways: Get rid of the %.bin rule, which seems wrong anyway, because it says that all .bin files depend on a fixed list of object files, and replace it by
$(BIN): $(OBJS)
# as before
or mark the object files as "secondary":
.SECONDARY: $(OBJS)
