When check.py is executed, the first call of check_file() (with argument "crypto.h") leads to an infinite loop within the recursive function utils.walkFiles(). The reason is that this function follows symbolic links to directories.
On my system the directory X contains the symbolic link "Y -> ." because X/Z and X/Y/Z shall be accessible for all entries Z without having the Zs twice on the disk. This is necessary because one program assume Z at X/Z and another program at X/Y/Z.
Anyhow, it is not a good practice to follow symbolic links at a directory descent. Because often an infinite loop starts at it is the case for check.py.
Obviously other users already had the same problem, because there is the question https://answers.launchpad.net/hplip/+question/36267 and the source code for walkFiles() contains the following comment:
# if os.path.islink(fullname):
# fullname = os.path.realpath(os.readlink(fullname))
When the comment chars are removed from these lines check.py works perfectly again.
check_file()
/usr/share/hplip/installer/dcheck.py
walkFiles()
/usr/share/hplip/base/utils.py
I found the same problem in my Linux distribution (Slackware 12.0), but when I uncommented the two lines it still did not work. Turns out that in /usr/include/
/usr/
/usr/
/usr/
Instead, I added the following to walkFiles after the assignment of fullname:
if os.path.
# log.debug("link: %s -> %s" % (fullname,
if linkname == ".":
This effectively skips over symbolic links that point to the current root.
This works for me. I've attached a copy of my revised utils.py.
