From 6995883a9b6f5260977d448a6ba044013d68b935 Mon Sep 17 00:00:00 2001 From: Vadim Kochan Date: Sun, 22 Nov 2015 21:09:39 +0200 Subject: cpp: Use /tmp folder for output files There might be a case when input file is located in read-only directory and cpp fails when it tries to create output file there, so use /tmp folder for that as usually it should be writeable for any user.
