Linking Error

Hello All, 
I am trying to compile my code and recieving a linking error as mentioned below...


 undefined reference to symbol 'typeinfo for itk::LightObject'
/usr/bin/ld: note: 'typeinfo for itk::LightObject' is defined in DSO /home/vigupta/Software/ITK/build/bin/libITKCommon.so.3.20 so try adding it to the linker command line
/home/vigupta/Software/ITK/build/bin/libITKCommon.so.3.20: could not read symbols: Invalid operation
collect2: ld returned 1 exit status


Has anyone encountered similar errors??
Thanks
Vikash

Re: Linking Error

Looks like your vtk libraries might be corrupt. Did you change c++
compilers recently? Try removing all of the vtk .so's and rebuild vtk.

Re: Linking Error

Hi Bill, 
Thanks for the help.. Well rebuilding ITK helped.. I dont see why they should be corrupt or anything just
because they are old ... :)

Re: Linking Error

Hi Vikash, 
Any chance you forgot to link ITKCommon with your program?

do you have the following line in your cmakelist  
TARGET_LINK_LIBRARIES(HelloWorld ITKCommon)
