Bug#1023653: coccinelle: Picks up wrong Python
Package: coccinelle
Version: 1.1.1.deb-1+b2
Severity: normal
X-Debbugs-Cc: ukleinek@debian.org, nicolas.palix@univ-grenoble-alpes.fr, julia.lawall@inria.fr
Hello,
when I run
/usr/bin/spatch -D report --no-show-diff --very-quiet --cocci-file scripts/coccinelle/api/kfree_mismatch.cocci --no-includes --include-headers --dir . -I ./arch/x86/include -I ./arch/x86/include/generated -I ./include -I ./arch/x86/include/uapi -I ./arch/x86/include/generated/uapi -I ./include/uapi -I ./include/generated/uapi --include ./include/linux/compiler-version.h --include ./include/linux/kconfig.h --jobs 4 --chunksize 1
in the kernel source tree (which is also what
make coccicheck COCCI=scripts/coccinelle/api/kfree_mismatch.cocci
does), I get:
Cannot find Python library
When running that under strace I see it tries to execute "python":
$ strace -f -e execve,openat /usr/bin/spatch -D report --no-show-diff --very-quiet --cocci-file scripts/coccinelle/api/kfree_mismatch.cocci --no-includes --include-headers --dir . -I ./arch/x86/include -I ./arch/x86/include/generated -I ./include -I ./arch/x86/include/uapi -I ./arch/x86/include/generated/uapi -I ./include/uapi -I ./include/generated/uapi --include ./include/linux/compiler-version.h --include ./include/linux/kconfig.h --jobs 4 --chunksize 1

Cannot find Python library

When installing python-is-python3 the spatch command above start to do
something sensible. I'm not entirely sure but I think this is a problem
in the coccinelle binary and not the cocci patch. As coccinelle depends
on python3:any it should better try to call python3 explicitly.
Best regards
Uwe
