Hello,

I tryied to search roottalk but I did not find any answer on that question.

I have been working with root 3.02/00 recently I changed to Version   3.02/07.
I have root files containing tree created by root 3.02./00 and when I am
trying to open it with the help  of the function in new root it gives an error
message.

treer1(){
gROOT->Reset();
TFile *file= new TFile("../src/15.04.2002.root","READ");
TTree *tree= (TTree*)file->Get("tree");
//TBrowser *br= new TBrowser();
tree->Print();
tree->Show(0);
}

it says:
Root > !!!Dictionary position not recorvered because G__unloadfile() in macro!!!
Function treer1() busy flag cleared

When I am doing the same by my compiled program I have this:

Error in <TStreamerInfo::Build>: TBranch, discarding: Int_t* fBasketBytes, illegal [fMaxBaskets] must be placed before

Error in <TStreamerInfo::Build>: TBranch, discarding: Int_t* fBasketEntry, illegal [fMaxBaskets] must be placed before

Error in <TStreamerInfo::Build>: TBranch, discarding: Seek_t* fBasketSeek, illegal [fMaxBaskets] must be placed before

Error in <TBuffer::CheckByteCount>: object of class TBranch read too few bytes
Warning in <TBuffer::CheckByteCount>: TBranch::Streamer() not in sync with data on file, fix Streamer()
Error in <TBuffer::CheckByteCount>: object of class TBranch read too few bytes

Warning in <TBuffer::CheckByteCount>: TBranch::Streamer() not in sync with data on file, fix Streamer()
Error in <TBuffer::CheckByteCount>: object of class TBranch read too few bytes
*** Break *** segmentation violation

So, how can I open and read files in root 3.02.07 created by the root 3.02.00 ?
Everything worked fine in the old version.

I am working under linux Mandrake 2.2.19-alt2 with gcc-2.96-ipl8mdk for root
3.02.07.
