Error cling::DynamicLibraryManager::loadLibrary() while compiling in root 6.08,

ROOT

Hi,

I am having following problem (errors) while compiling my code in root 6.08, was working fine in root 5.34/36.

root [0] .L BCR_PDF.C+
Info in TUnixSystem::ACLiC: creating shared library /home/iwsatlas1/ritu/highxp/./BCR_PDF_C.so

Any idea what is happening?

Can you post a script reproducing this problem ?

Hi,

Please find attached.

Ritu.

BCR_PDF.C (10.5 KB)

BCR_PDF.h (2.69 KB)

I tried your macro with 6.14. I had only to change:

#include <BCR_PDF.h>

into:

#include "BCR_PDF.h"

Then it works for me…

Hi Again,

Yes it did work for me.

But now if I include these files in a simple .C and .h files created using MakeClass, it is not compiling and giving following errors, it use to somehow work in earlier versions.

Could you please have a look?

the errors are:

//========================================================

Also if I just comment out ClassImp(BCR_PDF) line in BCR_PDF.h file, it atleast compiles, but is there

any other better way to do it?

To compile I used the command

root [0] .L highx_p.C+

The files are attached for your reference.

highx_p.C (1.49 KB)

highx_p.h (74.3 KB)

Simply remove ClassImp(BCR_PDF);; it’s not needed, neither for ROOT 5 nor 6.

Hi Axel,

I commented the line ClassImp(BCR_PDF);

But I got the errors after I did
.L highx_p.C+
//================================================================

//========================

And if I load BCR_PDF.C via .L BCR_PDF.C+

I get errors stating redefinition of every function that is in BCR_PDF

8 
.L BCR_PDF.C+
.L highx_p.C+

should work, if not, please paste the error message.
