Re: [eigen] Some compilation warning

[Gael Guennebaud <gael.guennebaud@xxxxxxxxx>]

They have been fixed in the devel branch through a significant refactoring of the usage of the Index type. See: http://eigen.tuxfamily.org/bz/show_bug.cgi?id=877

Dear all,

why does the number of rows and columns of a matrix is stored as

"long" instead of "unsigned long" or maybe better yet "size_t" ?

When compiling an application using EIGEN with

clang++ -Weverything -std=c++11

I got many EIGEN related warnings. For example:

SIGN_CONVERSION:

/home/mathieu/opt/eigen/Eigen/src/Core/util/Memory.h:835:26: warning: implicit conversion changes signedness: 'int' to 

'unsigned int' [-Wsign-conversion]

      int ways        = (abcd[1] & 0xFFC00000) >> 22; // B[31:22]

DEPRECATED:

/home/mathieu/opt/eigen/Eigen/src/Core/PlainObjectBase.h:132:5: warning: dynamic exception specifications are deprecated [-Wdeprecated]

    EIGEN_MAKE_ALIGNED_OPERATOR_NEW_IF(NeedsToAlign)

and some other warnings.

Is there an interest in correcting those?
