Hi Jyothsna,

The important part of the message is:

/work/red-clued0/jyothsna/Higgs/bbh120/fileeroLPt.C:5323: undefined
reference to `bbh_anal::Loop(void)'

This indicates that somehow, a member function bbh_anal::Loop() is declared
and used but is not implemented.  Please check your bbh_anal.h and
bbh_anal.C to make sure that they agree is usage and definition of this
member function.

Cheers,
Philippe.

Hi,

When I tried compiling my macro using the command:
gROOT->LoadMacro("bbh_anal.C+")

I get the following error message:
-------------------------
/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../crt1.o: In function
`_start':
/usr/lib/gcc-lib/i386-redhat-linux/2.96/../../../crt1.o(.text+0x18):
undefined reference to `main'
/work/red-clued0/jyothsna/Higgs/bbh120/./fileeroLPt.o: In function
`G__bbh_anal_Loop_6_0__FP8G__valuePCcP8G__parami':
/work/red-clued0/jyothsna/Higgs/bbh120/fileeroLPt.C:5323: undefined
reference to `bbh_anal::Loop(void)'
collect2: ld returned 1 exit status
*** Interpreter error recovered ***
--------------------------

I'm using root version v3_03_07d (KCC_4_0) on Linux-2-4.

I've used the options:

TString comp = gSystem->GetMakeSharedLib();
comp.ReplaceAll(" +K3"," -g");
comp.ReplaceAll(" +K2"," -g");
comp.ReplaceAll(" +K1"," -g");
comp.ReplaceAll(" -O2"," -g");
comp.ReplaceAll(" -O1"," -g");
gSystem->SetMakeSharedLib(comp.Data());

before loading my macro.

Can anyone tell me what does the above error message mean and ofcourse a
soln for it???

Thanks a lot,
Jyothsna
