Hi everyone,
Sorry, I know this topic has been raised quite often already but I’m confused.
First of all, I’m running the ROOT v5.12/00 binary for Mac OS X (PPC) with gcc 4.0.1.
The problem is the following: from the cint command line ‘vector’ works but ‘vector’ does not. More specifically:

W E L C O M E to R O O T * -
* - Version 5.12/00 10 July 2006 *

FreeType Engine v2.1.9 used to render TrueType fonts.
Compiled on 11 July 2006 for macosx with thread support.
CINT/ROOT C/C++ Interpreter version 5.16.13, June 8, 2006
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
rroot [0] vector a
root [1] a
(class vector)49092736
root [2] a.resize(4)
root [3] vector b
root [4] b
(class vector)49097728
root [5] b.resize(4)
Error: Can’t call vector<int,allocator >::resize(4) in current scope (tmpfile):1:
Possible candidates are…
(in vector<int,allocator >)
*** Interpreter error recovered ***
root [6]
Trying vector<Int_t> does not help, typing ‘b.’ and hitting tab tells me ‘Warning in : no dictionary for class vector is available’.
So I’m confused about a few things:
- how come it allows me to instantiate b, if it does not know of such a thing?
- what exactly is built by ‘gmake cintdlls’ (which I guess has been part of the binary build)?
- Where does the information for the cintdlls come from? I downloaded the 5.12/00 source and grepped through all linkdef files. I can find vector in ./base/inc/LinkDef2.h with the familiar syntax:
#pragma link C++ class vector;
But I can only find vector in ./metautils/src/vectorLinkdef.h (where the name metautils makes me wonder if I’m not looking in the wrong place) as
#pragma create TClass vector;
Who can tell me what that does?
Anyway, sorry for the rather long post but I wanted to show that I did dig and tried to find the solution. But I’m stuck.
Thanks for your help,
Jeroen
P.S. I did find this

thread but I’m already running the mentioned binary and Axel’s little test fails for me.
