[Gdal-dev] gdal config icluding xerces

[Daniel Isenegger]

Hi
after some problems with installing Xerces in default paths, i think i 
overcome (with the patient help of Frank) this problems (now it seems 
that gdal finds the Xerces libs and includes), at least i got a new 
error message (:-)

checking for Xerces C++... requested, but compile or link fails!

./configure --with-grass=/usr/local/grass-5.7.0 
--with-pg=/usr/local/pgsql/bin/pg_config --with-xerces 
--with-odbc=/usr/local/lib --with-static-proj4=/usr/lib/libproj.so | tee 
configure_disen.log


g++ -I/usr/local/include/xercesc -o conftest conftest.cpp 
-L/usr/local/lib -lxerces-c -L/usr/local/grass-5.7.0 
-L/usr/local/grass-5.7.0/lib -lgrass5 -lz -lm -ldl

/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../../../i586-suse-linux/bin/ld: 
cannot find -lgrass5
collect2: ld returned 1 exit status

what i don't understand here:
is still Xerces causing the problem or is it grass

for info:
grass57 installed in /usr/local/grass-5.7.0 (as indicated in 
config-statement)

Thanks Dani
