[Insight-developers] gcc 3.3.1 causing problems with itk::FEM LinearSystemWrapperItpack

[Lorensen, William E (Research)]

Sounds like the code should be fixed. Have you tried your changes locally?
If they work, send Brad the changes.

Subject: [Insight-developers] gcc 3.3.1 causing problems with
itk::FEMLinearSystemWrapperItpack


I know that people are busy with the whole lockdown thing, but ...

I recently built gcc 3.3.1 on Linux, and it is having some problems with 
itkFEMLinearSystemWrapperItpack.cxx, specifically with initializing the 
m_Methods member data.  The compiler error is


.../Insight/Code/Numerics/FEM/itkFEMLinearSystemWrapperItpack.cxx:36: error:

invalid
   conversion from `int (*)(integer*, integer*, integer*, doublereal*, 
   doublereal*, doublereal*, integer*, integer*, doublereal*, integer*, 
   doublereal*, integer*)' to `int (*)(int*, int*, int*, double*, double*, 
   double*, int*, int*, double*, int*, double*, int*)'

I think I know what's going on -- in the latest revision, the f2c typedefs
for 
integer and doublereal were copied from f2c.h into 
itkFEMLinearSystemWrapperItPack, so that f2c.h is only included in the .cxx 
file, and not the .h file.

A laudible goal, but apparently gcc 3.3.1 thinks the typedefs inside the 
itk::LinearSystemWrapperItpack define a different type than the typedefs in 
f2c.h, so the function signatures don't match.

So is the solution to NOT use gcc 3.3.1, or is there a better way to handle 
the type issues?
