+++ This issue was initially created as a clone of Issue #127461 +++

A new release, expat 2.2.2, is available:
Comment 1 Jim Jagielski 2017-08-03 01:40:13 UTC
Version 2.2.3 has just been released.
Comment 2 Jim Jagielski 2017-08-03 02:17:55 UTC
See r1803939

You'll probably find that this doesn't build correctly on the old Linux distros that we have to support.  Even CentOS 7 doesn't have a recent enough version of glibc to get good entropy.

The patch in expat-2.2.x.patch will probably need to contain this
modification for Linux:

+.IF "$(OS)"=="WNT"
+.ELIF "$(OS)"=="LINUX"
Comment 4 Don Lewis 2017-08-03 06:13:07 UTC
The Linux build problem appears to be fixed in 2.2.3, which added a fallback to /dev/urandom.  I was able to get trunk to build as-is with 2.2.3 on CentOS 7.
