* Use LAPACK_xxxx to transparently (via predefined lapack macros) deal with pre and post 3.9.1 versions.
|
|
* LAPACK 3.9.1 introduces LAPACK_FORTRAN_STRLEN_END and modifies (through preprocessing) the declarations of the following functions used in opencv
|
|
* sposv_, dposv_, spotrf_, dpotrf_, sgesdd_, dgesdd_, sgels_, dgels_
|
|
* which end up with an extra parameter.
|
|
* So we also need to preprocess the function calls in opencv coding by prefixing them with LAPACK_.
|
|
* The good news is the preprocessing works fine whatever netlib's LAPACK version.
