commit 4c6219dc621d139cd39e8aaca578dd69b9c063d0 Author: Nicolas Vigier boklm@torproject.org Date: Mon Apr 10 16:07:23 2017 +0200

Bug 21907: Fix runtime error on CentOS 6

In Mozilla bug 1324780, support for building with glib 2.28 (the version available in CentOS 6) was added. However we are building on Debian Wheezy which has glib 2.32. We fix that by backing out all glib > 2.28 code paths. --- gfx/harfbuzz/src/hb-glib.cc | 41 ----------------------------------------- gfx/harfbuzz/src/hb-glib.h | 5 ----- 2 files changed, 46 deletions(-)
