I suggest to take another look at the corresponding software development history.
The build infrastructures were occasionally updated in the meantime.

elfring@Sonne:~> SP=$(which spatch) && file $SP && du -h $SP

OK.  I don't install Coccinelle in the normal way.  I will check on what
is intended.

Sorry.  This problem has no impact, but I just pushed a commit to github
to solve it.

Yes, I saw scripts/spatch, but that script is not what is installed in
/usr/local/bin.

OK, I did all of those.

Is this expected?

$ ./autogen
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory
cat: VERSION: No such file or directory


spatch is installed in /usr/local/bin/spatch:

$ ll /usr/local/bin/spatch
-rwxr-xr-x 1 root root 15547736 Jun 14 07:32 /usr/local/bin/spatch*

$ file /usr/local/bin/spatch
/usr/local/bin/spatch: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/l, BuildID[sha1]=2b658c12a1a49deae24010b71d22d262988ce041, for GNU/Linux 3.2.0, with debug_info, not stripped


I still get this runtime error:

Python error: No module named coccilib.elems

Yes, I'm aware of this problem.  We're not able to update the home page at
the moment.  This problem is being worked on.

Actually, it is a script, and the fact that you say it is a binary may be
the reason for your python problem.  Normally there is a script
(scripts/spatch) that make install puts in place that refers back to where
your Coccinelle is installed.

OK.  A lot of documentation for a lot of projects seems to omit the sudo,
but I have indeed never understood why.

Maybe try again with make distclean, ./autogen, ./configure, sudo make
install?
