I am building qemu on an old system with python 2.4.3. The latest checkin:
commit 9d34158a5af734e8de0b42b0a7228200c426a8d0 Merge: 8f1ed5f bd80a8a Author: Peter Maydell <peter.mayd...@linaro.org> Date: Mon Sep 7 16:07:47 2015 +0100 Merge remote-tracking branch 'remotes/cohuck/tags/s390x-20150907' into staging caused my qemu build to fail with: File "/scratch/gcc/nightly/src/qemu/scripts/qapi.py", line 947, in cgen raw = re.subn("^.", indent + r'\g<0>', raw, 0, re.MULTILINE) raw = re.subn("^.", indent + r'\g<0>', raw, 0, re.MULTILINE) TypeError: subn() : subn() takes at most 4 arguments (5 given) Now the recent patch did not introduce the use of subn, it just seems to have changed something so that I call it now whereas before I did not. The actual use of subn was introduced with this qemu patch: commit 77e703b861d34bb2879f3e845482d5cf0a3a0ad1 Author: Markus Armbruster <arm...@redhat.com> Date: Wed Jun 24 19:27:32 2015 +0200 qapi: Clean up cgen() and mcgen() It looks like the 5th (optional) argument to subn in python was added with python 2.7 and I am using python 2.4.3. Is the use of the 5th argument on subn needed? And is it intentional that qemu cannot be built without a python 2.7 or later? Steve Ellcey sell...@imgtec.com
