I've been out of touch with Hugin for a while, and decided to try building
the sources from the HG depot on the Mac. I updated the dependencies using
MacPorts.
I get the following warning:
#warning LAPACK not available, LU will be used for matrix inversion when
computing the covariance; this might be unstable at times
However, the Mac has LAPACK built in
*LAPACK*
LAPACK provides routines for solving systems of simultaneous
linear equations, least-squares solutions
of linear systems of equations, eigenvalue problems, and singular
value problems. The associated
matrix factorizations (LU, Cholesky, QR, SVD, Schur, generalized
Schur) are also provided, as are
related computations such as reordering of the Schur
factorizations and estimating condition numbers.
Dense and banded matrices are handled, but not general sparse
matrices. In all areas, similar function-ality functionality
ality is provided for real and complex matrices, in both single
and double precision. LAPACK in vecLib
makes full use of the optimized BLAS and fully benefits from
their performance. All the industry stan-dard standard
dard FORTRAN LAPACK entry points are exported from the vecLib
framework. C programs may make calls to
the FORTRAN entry points using the prototypes set out in
"/System/Library/Frameworks/vecLib.frame-work/Headers/clapack.h".
"/System/Library/Frameworks/vecLib.framework/Headers/clapack.h".
work/Headers/clapack.h".
It is optimized using SSE, too.
Has someone already tweaked cmake or something to include this?
