#HOW TO INSTALL OPENMP ON MAC WINDOWS#
The Ceresīuild system will automatically detect and use it.įor Windows things are much more complicated. Implementation as part of the Accelerate framework. MacOS ships with an optimized LAPACK and BLAS Inside OpenBLAS as it conflicts with use of threads in Ceres. On UNIX OSes other than macOS we recommend ATLAS, which includes BLAS and SuiteSparse, and optionally used by Ceres directly for some Solving sparse linear systems across macOS, iOS et al. OptionalĪs of Xcode 9.0, Apple’s Accelerate framework includes support for
This makes for a simplerīuild process and a smaller binary. Similar to SuiteSparse but simpler and slower. You can customize the searched TBB location SuiteSparseQR was compiled with TBB support and will link to theįound TBB version. If SuiteSparseQR is found, Ceres attempts to find the Intel Glog and is much harder to control and use.
There is nothing preventing the user from doing so, we strongly Miniglog on platforms which already support glog. In an attempt to reduce dependencies, it may be tempting to use
#HOW TO INSTALL OPENMP ON MAC FULL#
Miniglog is supplied for platforms which do not support the full Miniglog that can be enabled with the MINIGLOG build option. To get more and more verbose and detailed information about CeresĬeres also ships with a minimal replacement of glog called logtostderr you can add -v=N for increasing values of N The Ceresĭevelopers use it extensively to observe and analyze Ceres’sĬontrol its behaviour from the command line. Parts of the solve, internal error conditions etc. Information about memory allocations and time consumed in various Glog is used extensively throughout Ceres for logging detailed Please see the documentation for EIGENSPARSE for Ceres can also use Eigen as a sparse linear algebra
