Re: [ROOT] use of '#define FOO' in macro

Hi,

sorry for the slow reply! -p invokes the external preprocessor - all
preprocessor macros will already be expanded when CINT sees your code.
It will thus not be able to use it.

Instead, do not use -p, and instead use the following hack. Put in your
Linkdef.h:
extern const bool b1;
#pragma link C++ global b1;

This way, CINT will know that b1 is a variable. And you don't have to
change the CCfits header files.

Cheers, Axel.

Re: [ROOT] Problems compiling root 5.15/04 on Solaris 10

Hi Francesco,

sorry for the late replay; seems like you didn't get an answer after
all? Could you send me the output of gmake install SHELL="/bin/sh -x"?
It's going to be a lot, so better pipe it into a file.

Cheers, Axel.

Hello Axel,

I tried your hack but it did not compile.

$ make
rootcint -f FITS.cxx -c -I/usr/local/include FITSfunctions.h  
FITSLinkDef.h
Syntax error /usr/local/include/CCfits/FITSUtil.h:322:
Warning: Error occurred during reading source files
Warning: Error occurred during dictionary source generation
!!!Removing FITS.cxx FITS.h !!!
Error: rootcint: error loading headers...
make: *** [FITS.cxx] Error 1

I attache four files.
- Makefile
- FITSfunctions.h
- FITSLinkDef.h
- rootfits.cxx

Would you check the files? There may be my mistakes. However
- CFITSIO http://heasarc.gsfc.nasa.gov/docs/software/fitsio/fitsio.html
- CCFITS http://heasarc.gsfc.nasa.gov/fitsio/CCfits/
are needed if you compile my code.

[ROOT] How to make TH1 recalculate stats?


Hello ROOTers,

How do I force ROOT to recompute the mean, RMS, etc. of a histogram  
after a SetBinContent operation?   I had thought that TH1::Rebuild()  
would do it but this seems not to be the case:

root [0] test = new TH1F("test","test",2,0,10)
(class TH1F*)0x7149a00
root [1] test->FillRandom("pol0",1000)
root [2] test->GetMean()
(const Double_t)5.01881719480501509e+00
root [3] test->SetBinContent(2,0)   // the mean should now be 2.5
root [4] test->GetMean()   // but it is not
(const Double_t)5.01881719480501509e+00
root [5] test->Rebuild()      //nothing seems to trigger a recalc  
based on bin contents
root [6] test->GetMean()
(const Double_t)5.01881719480501509e+00
root [7] test->Add(test,1e-5)
root [8] test->GetMean()
(const Double_t)5.01881719480501509e+00
root [9] test->Fill(7,1e-5)
(Int_t)2
root [10] test->GetMean()
(const Double_t)5.01881721461664476e+00
root [11] test->Sumw2()
root [12] test->GetMean()
(const Double_t)5.01881721461664476e+00
root [13] test->Rebuild()

[ROOT] macro works on 5.14.00, fails on 5.15.08; Windows

I tried the latest Root release 5.15.08 on my Windows VM, but my macro 
crashes Root after typing a message to stdout but before displaying its 
GUI dialog box. I get stacktraces for 3 threads, each with 2 or 3 
entries, none of which mention any part of my code at all.

This macro works fine on Root 5.14.00, on Windows, Mac OS, and Linux. I 
have tried 5.15 only on Windows.

This is a 1000-line macro and I can only provide a .tiff image of the 
stacktraces, so I'm not posting them to the list. If anyone wants to 
look at them, respond privately.

This is my HistoRoot.C macro that provides a user-friendly interface to 
constructing histograms from NTuples in Root files. It is in some sense 
a Root implementation of the old HistoScope program.

Hi Tom,

Please send me the stack trace, and if possible the macro.

Cheers,
Bertrand.

[ROOT] h2root script

Hi rooters,
I have to convert some MC samples stored in ntpl files in rootfiles.

Does anybody know where the h2root program puts the information of
"Isthep" (i.e.codes relevant to know whether the particle dacayed or not)?

Thank you very much,
     Danilo Piparo

Re: [ROOT] h2root script

h2root does not know anything about Isthep. If this is a column in your 
ntuple, it should be converted automatically into a branch of a ROOT 
Tree. If this is not teh case
  -indicate which version of ROOT you are using
  -post a small hbook file to be converted

[ROOT] atom error

Hi-
I'm using SSH and X11 on Mac OSX to open a root file on a remote  
server. When I attempt to open a TBrowser, I get an "atom" error.  
Does documentation on errors and their meanings exist somewhere on  
the web?
cheers

Re: [ROOT] atom error

William,

> When I attempt to open a TBrowser, I get an "atom" error.

is a problem with X11 forwarding. Use '-X' or '-Y' as an argument to your
ssh connection. See 'man ssh' for details.

Best regards,
           Wim
