vitis hls 2020.2 Pre-synthesis failed, but it didn't prompt any errors. How can I find out the cause of the error and fix it？

Question

#define READ_COL 4
void read_data(kern_colmeta *colmeta
         , int ncols
        , HeapTupleHeaderData *htup
        , cl_char tup_dclass[READ_COL]
        , cl_long   tup_values[READ_COL])
{
        char        *addr ;//__attribute__((unused));
        EXTRACT_HEAP_TUPLE_BEGIN(addr, colmeta, ncols, htup);
        EXTRACT_HEAP_TUPLE_NEXT(addr);
        EXTRACT_HEAP_TUPLE_NEXT(addr);
        EXTRACT_HEAP_READ_32BIT(addr, tup_dclass[3],tup_values[3]); 
        EXTRACT_HEAP_TUPLE_NEXT(addr);
        EXTRACT_HEAP_TUPLE_NEXT(addr);
        EXTRACT_HEAP_TUPLE_NEXT(addr);
        //EXTRACT_HEAP_READ_POINTER(addr,tup_dclass[1],tup_values[1]); 
        EXTRACT_HEAP_TUPLE_NEXT(addr);
        //EXTRACT_HEAP_READ_POINTER(addr ,tup_dclass[2],tup_values[2]);
        EXTRACT_HEAP_TUPLE_END();
}

void accel (char *a, char *b)//, int* o)
{
#pragma HLS INTERFACE m_axi depth=125    port=a
#pragma HLS INTERFACE m_axi depth=1984    port=b
    kern_colmeta col[16];
    memcpy(col, b, sizeof(kern_colmeta)*16);
    HeapTupleHeaderData *htup;
    htup = (HeapTupleHeaderData *)a;
    cl_char tup_dclass[READ_COL];
    cl_long   tup_values[READ_COL];
    read_data(col, 16, htup, tup_dclass, tup_values);
}

The top function is accel(), error occurs in the code when calling EXTRACT_HEAP_READ_32BIT(). C simulation results are normal，but as once try to run synthesis, it faild. error log just like as follows:

Answer 1

I have exactly the same error:

INFO: [HLS 200-111] Finished Command csynth_design CPU user time: 45.76 seconds. CPU system time: 0.94 seconds. Elapsed time: 46.21 seconds; current allocated memory: 194.761 MB.
Pre-synthesis failed.
    while executing
"source ../scripts/ip_v6.tcl"

I would be interested to know how I can track the error source. I also have the same error message if I launch viti_hls GUI.
