RE: ROOT Stable And 5-D Vector

Hi Chris,

The problem that some of the name produced are too long for some of the fixed length buffer internal to CINT (yes we are working on removing those). To work-around the problem you need to recompile ROOT with the CPP macro   G__LONGBUF
defined (better yet modify G__ci.h to contained #define G__LONGBUF).

Subject: [ROOT] ROOT Stable And 5-D Vector

I'm not sure if this has been discussed before but here goes. I am able to easily compile things so that they can be loaded into root as shared libraries. However, if I use a vector of dimensions greater than 4, such as this:
  vector <vector <vector <vector <vector <float> > > > > flt_1; I cause rootcint to segfault when it's generating the dictionaries:
[chris_at_odin root]$ make

Generating dictionary VhistDict.cxx...

Info: Class Vhist: Streamer() not declared
make: *** [VhistDict.cxx] Segmentation fault
make: *** Deleting file `VhistDict.cxx'

[chris_at_odin root]$ rootcint -f VhistDict.cxx -c Vhist.h
Segmentation fault

Once again, this is on version 4.04/02, one of the prebuilt ones for RH9. Can
anyone else tell me if they get the same problems on other builds. This is the
only install I have of root that I know is working properly!

Note: I do seem to be able to load this library inside of root: .L Vhist.cpp++
and it seems to work fine. Received on Mon May 23 2005 - 21:13:18 MEST
