v.kriging add on install missing BLAS libraries on Windows

[fanfanchart]

Hi,

When installing the add on v.krige and running it, the error message (see below) indicates that

https://grass.osgeo.org/grass74/manuals/addons/ --> Windows log files

--> vector/v.kriging FAILED log

--> ​http://wingrass.fsv.cvut.cz/grass74/x86/addons/latest/logs/v.kriging.log

" #error GRASS GIS is not configured with BLAS (la.h cannot be included) "

This means that the LAPACK/BLAS numerical libraries are apparently not installed/activated on the wingrass server on which the WinGRASS addons are built.

see below: ​https://trac.osgeo.org/grass/browser/grass/branches/releasebranch_7_4/mswindows/osgeo4w/package.sh#L168

for the compilation configuration of winGRASS:

168 LDFLAGS="-L$PWD/mswindows/osgeo4w/lib -lz" ./configure \ 169 --host=$conf_host \ 170 --with-libs="$PWD/mswindows/osgeo4w/lib "\ 171 --with-includes=$OSGEO4W_ROOT_MSYS/include \ 172 --libexecdir=$OSGEO4W_ROOT_MSYS/bin \ 173 --prefix=$OSGEO4W_ROOT_MSYS/apps/grass \ 174 --bindir=$OSGEO4W_ROOT_MSYS/bin \ 175 --includedir=$OSGEO4W_ROOT_MSYS/include \ 176 --without-x \ 177 --with-cxx \ 178 --enable-shared \ 179 --enable-largefile \ 180 --with-fftw \ 181 --with-freetype \ 182 --with-proj-share=$OSGEO4W_ROOT_MSYS/share/proj \ 183 --with-gdal=$PWD/mswindows/osgeo4w/gdal-config \ 184 --with-geos=$PWD/mswindows/osgeo4w/geos-config \ 185 --with-sqlite \ 186 --with-regex \ 187 --with-nls \ 188 --with-freetype-includes=$OSGEO4W_ROOT_MSYS/include/freetype2 \ 189 --with-odbc \ 190 --with-cairo \ 191 --with-postgres \ 192 --with-opengl=windows \ 193 --with-bzlib $conf_opts

and see addon compilation log: (​https://wingrass.fsv.cvut.cz/grass77/x86_64/addons/grass-7.7.svn/logs/v.kriging.log)

open an enhancement ticket to include BLAS into winGRASS.

This issue does not affect v.krige as it serves as a fronted for R.

Replying to martinl:

​msys2 (as building environment) has following packages:

mingw/mingw-w64-openblas 0.3.0-1
An optimized BLAS library based on GotoBLAS2 1.13 BSD, providing optimized blas, lapack, and cblas (mingw-w64)

mingw/mingw-w64-lapack 3.8.0-1
Linear Algebra PACKage (mingw-w64)

or including it in OSGeo4W as we need it then when running GRASSß
