Hi,
If any of you has experience with writing makefiles, please solve
my problem.
I am writing a makefile, and I have variable TOOL_STATUS.
Suppose I run cmp on two files, I want that the exit status of the
cmp command is saved in TOOL_STATUS. How do I do that.
As make runs each command in a separate sub-shell, that is the
biggest problem. I tried to give,
$(TOOL) File1, File2; override $(TOOL_STATUS) = $?
But it says override command not found.
Here the value of $(TOOL) is cmp.
Actually, I want to run diff command depending on the status of
cmp, i-e only if the exit status is 1, indicating a difference in
the files.
And to save the output to a file. This I have to do for some 100
files.
Can anybody solve this problem.
Regards,
