Error thrown when compiling write_rect2d.c code

[Chunhui92]

Dear developer,

I am trying to generate a .silo file using SILO functions DBPutQuadmesh, DBCreate, etc. The code is as below:

#include <silo.h>
#include <stdio.h>

void
write_rect2d(DBfile *dbfile)
{
    /* Write a rectilinear mesh. */
    float x[] = {0., 1., 2.5, 5.};
    float y[] = {0., 2., 2.25, 2.55,  5.};
    int dims[] = {4, 5};
    int ndims = 2;
    float *coords[] = {x, y};
    DBPutQuadmesh(dbfile, "quadmesh", NULL, coords, dims, ndims,
                  DB_FLOAT, DB_COLLINEAR, NULL);
}

int
main(int argc, char *argv[])
{
    DBfile *dbfile = NULL;
    /* Open the Silo file */
    dbfile = DBCreate("rect2d.silo", DB_CLOBBER, DB_LOCAL,
        "2D rectilinear mesh", DB_HDF5);
    if(dbfile == NULL)
    {
        fprintf(stderr, "Could not create Silo file!\n");
        return -1;
    }

    /* Add other Silo calls here. */
    write_rect2d(dbfile);

    /* Close the Silo file. */
    DBClose(dbfile);
    return 0;
}

The code was compiled with the command:
g++ -I/path/to/silo410/include write_rect2d.c -L/path/to/silo410/lib

and an error was thrown:

/tmp/ccaXtaW8.o: In function `write_rect2d(DBfile*)':
write_rect2d.c:(.text+0xe0): undefined reference to `DBPutQuadmesh'
/tmp/ccaXtaW8.o: In function 'main':

write_rect2d.c:(.text+0x183): undefined reference to `DBClose'
collect2: error: ld returned 1 exit status

Did I make some mistakes for compiling? Thank you!

Sorry for the naive question, it is solved by linking to libsilo.a
