Details:
I need to put in Makefile printf command to write 4 special bytes to the
file.
printf '\x00\x00\x8f\x60' > generated_file.bin
But I've met with a problem. This command works as expected if run it from the
command line. But, in Makefile, it produces the wrong result.
MakeFile content (simplified to demonstrate the issue):
generated_file:
printf '\x00\x00\x8f\x60' > generated_file.bin
Steps of how to run and get result:
$ make
printf '\x00\x00\x8f\x60' > generated_file.bin
$ hexdump generated_file.bin
0000000 785c 3030 785c 3030 785c 6638 785c 3036
0000010
$ cat generated_file.bin
\x00\x00\x8f\x60
The expected result is:
$ printf '\x00\x00\x8f\x60' > generated_file.bin
$ hexdump generated_file.bin
0000000 0000 608f
0000004
The version of used make tool is 4.1.
