Hello,

i very much like Eigen due to it's ease of use and it would be highly
useful in my current project, which requires a sparse linear solver.

However, whenever I include sparse functionality, e.g., by just adding

#include <Eigen/Sparse>

into my vs2010 project, the optimizing compiler will immediately crash with the message

SparseCore/SparseTranspose.h(48): fatal error C1001: An internal error has occurred in the compiler.

There seems to be no way around this bug, if i comment out the code on this location, the same error message will appear at a different line in the code. The only thing I could figure out was that the compiler probably does not like the template structure.

Any other suggestions?

greetings,
Oliver

Which Eigen version are you using? I remember that MSVC2010 worked fine with the sparse module. Perhaps you could also check whether you have a MSVC2010 with all the available bug corrections.

thanks for the quick reply! I'm using the 3.1.0 alpha version of Eigen.

In the meantime I set up another project in VS2010 which just includes the first simple example program from the Eigen tutorial and included <Eigen/Sparse>. and this time it was compiling alright! i tried to use the same compiler settings as in my main project, but while one compiles, the other crashes.

installing the service pack 1 for VS did not help, he keeps crashing when compiling these nested template classes of the form

class TransposeImpl<MatrixType,Sparse>::InnerIterator

no clue what causes these conflicts ...

i think found the problem! apparently it's the "enable browse" compiler option /FR which causes the compiler to crash with the sparse template classes.

greetings,
Oliver

ok, good to know, this is something we could add in the doc
