Hi, Yesterday, one of GDAL users reported that GDAL CVS does not build with GEOS 2.2.3. I investigated the problem and noticed two issues. The first one is related to GDAL autotools (already fixed). But the second one seems to be related to GEOS itsef.
I downloaded fresh GEOS 2.2.3 release and build it in standard way: $ ./configure $ make $ sudo make install Next, I checkouted GDAL from CVS and tried to build it too. The libgdal library builds and links well, but linking OGR utilities fails with following message: /bin/sh /home/mloskot/tmp/gdal-cvs/gdal/libtool --mode=link g++ ogrinfo.o /home/mloskot/tmp/gdal-cvs/gdal/libgdal.la -o ogrinfo g++ ogrinfo.o -o .libs/ogrinfo /home/mloskot/tmp/gdal-cvs/gdal/.libs/libgdal.so -L/usr/local/lib -L/usr/lib -lpq -lrt -ldl -lpthread /usr/local/lib/libgeos_c.so.1: undefined reference to `geos::WKBReader::read(std::basic_istream<char, std::char_traits<char> >&)' /usr/local/lib/libgeos_c.so.1: undefined reference to `geos::WKBWriter::write(geos::Geometry const&, std::basic_ostream<char, std::char_traits<char> >&)' /usr/local/lib/libgeos_c.so.1: undefined reference to `geos::Point::getCoordinatesRO() const' /usr/local/lib/libgeos_c.so.1: undefined reference to `geos::WKBWriter::WKBWriter(int, int)' collect2: ld returned 1 exit status make[1]: *** [ogrinfo] Error 1 make[1]: Leaving directory `/home/mloskot/tmp/gdal-cvs/gdal/ogr' make: *** [ogr-apps] Error 2 I checked 2.2.3 sources and all calls listed above are declared (.h) and defined (.cpp) properly. It seems to be a problem with -lgeos -lgeos_c linking but I'm not sure. Any ideas?
