[Insight-users] Help with compilation issue: expected class-name before '{' token

[Martin Kavec]

Hi,

I would very much appreciate if some could help me with compilation problem I 
have. Perhaps it's a bit late (2.30 am) and I am not able find out myself, 
where is the issue.

I use Gentoo linux, gcc-3.4.5 and ITK-2.6.0. I set up a project, where I 
define a class A (inheriting from itkObject) and class B (inheriting from A). 
In this configuration I am not able to compile a test file for B. If I 
implement everything in A, the code compiles.

Here is the compiler output:

c++ -ftemplate-depth-50 -g -I/opt/ITK_debug/Utilities/vxl/core 
-I/opt/ITK_debug/Utilities/vxl/vcl -I/opt/ITK-2.6.0/Utilities/vxl/core

I also attach the sources and CMakeList.txt.

Thanks in advance.
