[mapserver-dev] hoto add new key in mapfiles

[Martin Kofahl]

Hi Daniel,
no luck when compiling:

g++ ... -o shp2img
./libmapserver.a(mapfile.o): In function `getCharacter': mapfile.c:212: undefined reference to `msyylineno'
./libmapserver.a(mapfile.o): In function `getInteger': mapfile.c:202: undefined reference to `msyylineno'
./libmapserver.a(mapfile.o): In function `getDouble': mapfile.c:189: undefined reference to `msyylineno'
./libmapserver.a(mapfile.o): In function `getString': mapfile.c:176: undefined reference to `msyylineno'
./libmapserver.a(mapfile.o): In function `loadHashTable': mapfile.c:1706: undefined reference to `msyylineno'
./libmapserver.a(mapfile.o):mapfile.c:244: more undefined references to `msyylineno' follow
collect2: ld returned 1 exit status


I did add '#define RESTRICTION 9999' nead the bottom of mapfile.h.
And I did add '<INITIAL>restriction { return(RESTRICTION); }' wight after resolution in maplexer.l. After make clean && make maplexer.c also contains this keyword, but make fails at the end with no other errors before.


I'd like to have a spatial filter at layers basis using polygons which might be derived from another DATA statement or, probably easier, from another layer similar to a postgis tileindex layer. I already got some help from the libgd-people. So far I only played with msDrawLayer, but handling cached label and featureinfos might be required, too.
