New submission from Alex Stewart <[email protected]>: The version of reflex distributed as http://cern.ch/wlav/reflex-2013-04- 23.tar.bz2 (referenced from http://doc.pypy.org/en/latest/cppyy.html) has a bug in genreflex which does not correctly generate cpp files when classes contain union members.
This bug appears to have been fixed in the Reflex found as part of the latest ROOT distribution (5.34/09), so it is possible to use genreflex from the full ROOT package instead, however: 1) Downloading and building ROOT properly (with Reflex enabled) is more complicated, and it doesn't appear to be designed to be installed anywhere other than in its own source directory (i.e. 'make install' does not put things in the right places to actually run) 2) The ROOT version does not build libcppyy_backend, so it is necessary to download and build both reflex-2013-04-23.tar.bz2 and ROOT, and then use an ugly combination of both to get things to both build and run on the same host. The workaround I have currently come up with is to build/install reflex-2013-04- 23.tar.bz2 (in /usr/local), build ROOT (in its own $ROOTSYS dir), and then: rm -rf /usr/local/lib/python2.7/dist-packages/Reflex cp -a $ROOTSYS/lib/python/genreflex/ /usr/local/lib/python2.7/dist- packages/Reflex (This is obviously an ugly hack, however, and I'm a little bit uneasy about generating source with a version of genreflex which is different than the version of libReflex it's designed to link against (though it seems to work so far)..) It's unclear how the current standalone reflex .tar.bz2 was generated, but would it be possible to create a new one based off of the ROOT 5.34 version to fix this issue? ---------- messages: 6026 nosy: Foogod, pypy-issue priority: bug release: 2.0 status: unread title: cppyy: Need newer genreflex ________________________________________ PyPy bug tracker <[email protected]> <https://bugs.pypy.org/issue1576> ________________________________________ _______________________________________________ pypy-issue mailing list [email protected] http://mail.python.org/mailman/listinfo/pypy-issue
