Help with H2ROOT

ROOT
1

Hi,
I don’t know if my problem is a mistake in building or a bad use of the command h2root or a bug in my file.
I have compiled the latest svn version of root in a Scientific Linux 5.3 32 bit OS where it is already compiled and installed cernlib 2005, icc ver 11 and ifort ver 11. My machine is a dual core Dell T110.

I used:

and

all works fine but h2root is giving me some error messages.

I want to convert this file: http://www.webalice.it/strano.evd/dummy.hbook with lrec=4096

If i wrote:

It returns:

RZIODO. Error at record = 2 LUN = 1007 IOSTAT = -1 RZOPEN. Error in the input file Cannot open fileHROPEN 0 Error on hropen was 3 Converting directory //example TFile** prova.root HBOOK file: dummy.hbook converted to ROOT TFile* prova.root HBOOK file: dummy.hbook converted to ROOT

and creates an empty root file.

If I don’t specify some parameters:

It crashes:

[code] RZOPEN. Cannot determine record length - EXCHANGE mode is used.

Hi,

Which version of ROOT are you using? With the trunk I am able to read your file fine with: $ h2root dummy.hbook prova.root 1 1 0 RZOPEN. Cannot determine record length - EXCHANGE mode is used. Converting directory //example TFile** prova.root HBOOK file: dummy.hbook converted to ROOT TFile* prova.root HBOOK file: dummy.hbook converted to ROOT KEY: TH1F h10;1 exp(7.65084) KEY: TH1F h100;1 sin(x)/x $ h2root dummy.hbook prova.root RZOPEN. Cannot determine record length - EXCHANGE mode is used. Converting directory //example TFile** prova.root HBOOK file: dummy.hbook converted to ROOT TFile* prova.root HBOOK file: dummy.hbook converted to ROOT KEY: TH1F h10;1 exp(7.65084) KEY: TH1F h100;1 sin(x)/xThus I am guessing that your record length might not be 4096 (I think it is 1024) and that you either have a build error or an older version of ROOT.

Cheers,
Philippe.

I can reproduce the problem with icc11 on my MAC. I am aware of alignment problems with this compiler.
Not sure that this can be fixed in the short term. I can convert your file on all other systems.

Thanks.

I have replaced the libminicern.so file with the precompiled one in the Dev 5.27/04 version and all worked. I think there is a problem about compiling this file in my enviroment.
