[Liblas-devel] c liblas problem

[Black, Michael (IS)]

Well -- this little program compiles just fine with "cc -o myprog myprog.c -llas"
Examining liblas.a I see both C and C++ routines in there.
Am I missing something?
 
#include<stdio.h>
#include "liblas/capi/liblas.h"
int main(int argc, char** argv)
{
 int i;
 LASReaderH reader = LASReader_Create(argv[1]);
 LASHeaderH header = LASReader_GetHeader(reader);
 int count=LASHeader_GetPointRecordsCount(header);
 LASPointH point;
 for(i=0;i<count;i++) {
        double x,y,z;
        point = LASReader_GetNextPoint(reader);
        x = LASPoint_GetX(point);
        y = LASPoint_GetY(point);
        z = LASPoint_GetZ(point);
        printf("%f %f %f\n",x,y,z);
 }
 LASReader_Destroy(reader);
 return 0;
}

OK, thanks.

Yes, this command is not enough.
This links only against C++ API, but C API is a separate library.
