Dear GSL, I recently needed to modify my code to include a definition for size_t, via #include <cstddef> as this was not available on a Debian Sid builder, when using gsl_spmatrix.h [1].
I believe more recent versions of GCC have been reducing the header scope, as this builds on Debian stable and testing without any difficulties. I have not spun up a sid image to be able to do test this locally, as this occurred within a cowbuilder environment. diff --git a/src/backend/filters/spatialAnalysis.cpp b/src/backend/filters/spatialAnalysis.cpp index 2453cbe..91faebf 100644 --- a/src/backend/filters/spatialAnalysis.cpp +++ b/src/backend/filters/spatialAnalysis.cpp @@ -15,6 +15,10 @@ * You should have received a copy of the GNU General Public License * along with this program.
