带筒仓库的g++静态链接问题

Question

我有一些使用筒仓库的示例代码：

#include <silo.h>
#include <iostream>
int main(int argc, char *argv[])
{
    DBfile *dbfile = NULL;
        /* Open the Silo file */
    dbfile = DBCreate("basic.silo" , DB_CLOBBER, DB_LOCAL,"Comment about the data", DB_HDF5);

    if(dbfile == NULL)
    {
        return -1;
    }
    /* Add other Silo calls here. */
    /* Close the Silo file. */
    DBClose(dbfile);
    return 0;
}

我通过macport安装了筒仓库。筒仓港口包括：

Port silo contains:
  /opt/local/include/ioperf.h
  /opt/local/include/pmpio.h
  /opt/local/include/silo.h
  /opt/local/include/silo.inc
  /opt/local/lib/libsiloh5.a
  /opt/local/lib/libsiloh5.la
  /opt/local/lib/libsiloh5.settings 

当我尝试用以下方法编译示例代码时：

g++ functions.cpp /opt/local/lib/libsiloh5.a 

我得到了一大串错误：

Undefined symbols for architecture x86_64:
  "_H5Aclose", referenced from:
      _db_hdf5_Open in libsiloh5.a(silo_hdf5.o)
      _db_hdf5_Create in libsiloh5.a(silo_hdf5.o)

      _db_hdf5_get_comp_var in libsiloh5.a(silo_hdf5.o)
      _copy_dir in libsiloh5.a(silo_hdf5.o)

这条线还在继续。

我做错了什么？

谢谢

您需要在HDF5库中链接。筒仓位于其他低级存储库之上，如PDB、NetCDF和HDF5。
