From 2de9d74fde42227c3265ec96416e6c8b4db910fa Mon Sep 17 00:00:00 2001 From: Martin Galvan Date: Sun, 18 Dec 2016 00:33:43 +0530 Subject: Add -B to python invocation to avoid generating pyc files Without -B, python invocations may result in generation of pyc files for modules within the source tree, which does not work well when the source tree is read-only. 2016-12-17 Martin Galvan * Rules (python-flags, python-invoke): New. ($(test-printers-out)): Use $(python-flags). --- Rules | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'Rules') diff --git a/Rules b/Rules index 9e02eb7ea7..fe18ce55de 100644 --- a/Rules +++ b/Rules @@ -260,6 +260,12 @@ ifneq "$(strip $(tests-printers))" "" # inside Makeconfig.
