Minimal changes were done to these files, basically removing static keywords for the functions getSRSbySRID, getSRIDbySRS and circ_tree_distance_tree_internal so that they can be called by MobilityDB.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>The basic idea of the build is that if a PostGIS version less than 3.0 is found, then library liblwgeom.so is loaded.

Indeed, I first built PostGIS 3.1.3 in my machine and therefore this build generated the right parameters for the files postgis_config.h and postgis_revision.h that are embedded in MobilityDB/postgis. This concerns in particular the setting of the machine endian constant. Therefore, we need to replicate in MobilityDB some of the configuration PostGIS makes in order to produce the right postgis_config.h and postgis_revision.h according to the machine characteristics at hand. I will work on that in the forthcoming days.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Esteban<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div></div></div></div></div></body></html>
