Problem with a symbol lookup [message #5016] Tue, 04 September 2007 13:05 Go to next message

Hi everybody.

I have a problem with my mvd code.

First of all: It Compiles.

When running the macro (calling the MvdRecoTask("Simple") ) it crashes with 
/data_hilbert/Software/fairroot/cbmsoft/tools/root/bin/root.exe: symbol lookup error: /home/ralfk/Pandaroot/build/lib/libMvdReco.so: undefined symbol: _ZN12MvdCalcStrip20CalcStripPointOnLineEdR8TVector2


This happens in the SimpleHitmaker.cxx, where I want to access the MvdCalcStrip::CalcStripPointOnLine() function. There is a similar calling with the MvdCalcFePixel and this works.

The thing is that I have the class MvdCalcStrip compiled into the library libMvd.so and my SimpleHitMaker is inside the libMvdReco.so. If I look inside the libraries I find this:
ralfk@pktw61:~/Pandaroot/pandaroot/macro/mvd/Ralf> nm ../../../../build/lib/libMvdReco.so | grep _ZN12MvdCalcStrip20CalcStripPointOnLineEdR8TVector2
         U _ZN12MvdCalcStrip20CalcStripPointOnLineEdR8TVector2
ralfk@pktw61:~/Pandaroot/pandaroot/macro/mvd/Ralf> nm ../../../../build/lib/libMvd.so | grep _ZN12MvdCalcStrip20CalcStripPointOnLineEdR8TVector2
0002ff20 T _ZN12MvdCalcStrip20CalcStripPointOnLineEdR8TVector2

It means the Function is undefined inside the LibMvdReco and it is there inside the LibMvd. I think there should be no Problem at all.
And I did load both libraries in the needed order.

Any Ideas?

Regards, Ralf.

Hallo Ralf,

can you commit these classes and the macro to SVN so I can reproduce this error!

Mohammad

Hi,

I committed my changes and the macros. To get the data please run in pandaroot/macros/mvd/Ralf the runsim.C and rundigi.C first before the runreco.C.

Thanks,
Ralf.

Hallo Ralf,

after SVN update I get your code, runsim.C and rundigi.C go without problems, but thr runreco.C crashes in the MvdDigiStrip::GetDetName() method, which should only return a TString?? Any way I did not see the problem with symbol lookup at all, So may be you should make clean and then re-make again!

the output of simreco.C :

Ok, well.

I found another strange error before calling the function and so it doesn't appear anymore.
Now I get some segfaults which are surely my own mistakes.

Cheers, Ralf.

Edit:
Yes, Now I somehow crashed my pointers to my data 
MvdDigiStrip::GetDetName (this=0x71)

I'll follow this...

Thanks for helping. Ralf.
