I'd prefer at least some alternatives. E.g. the following xxd.py
#!/usr/bin/python
import sys
with open(sys.argv[1],"rb") as f:
nextblock = f.read(12)
while 1:
block = nextblock
nextblock = f.read(12)
if block == "":
break
str = ""
for ch in block:
if str == "":
str = " "
else:
str += ", "
if ord(ch) < 10:
str += "0x0" + chr(ord('0')+ord(ch))
elif ord(ch) < 16:
str += "0x0" + chr(ord('a')+ord(ch)-10)
else:
str += hex(ord(ch))
if nextblock != "":
str += ","
print str
python ./xxd.py $< >> $@
does the same thing as
cat $< | xxd -include >> $@
(CCing David as python expert, my python knowledge is limited and
15 years old, not sure how portable this is (python 2 vs. python 3, and
even python 2 minimal versions)).
Thus, perhaps configure could check for python that can handle this,
or xxd, and substitute the right command into the makefile and
only bail out if neither is found?
