SV DPI: veriusertfs

archive

Hi,

I'm trying to compile C file that contain the following:

#include
#include
#include
#include "veriuser.h"
#include "acc_user.h"
....
....

s_tfcell veriusertfs[] = {
//{userfunction, 0, 0, fio_size32, myfclose, 0, "$myfclose"},
{usertask, 0, 0, 0, myfopen, 0, "$myfopen"},
{usertask, 0, 0, 0, myfclose, 0, "$myfclose"},
...
...
{0} //
};

the problem is that the compiler (gcc c-file.c -c -I /include -o c-file.o) didn't recognize s_tfcell veriusertfs[], I have get the following message:

//372: parse error before "veriusertfs"
//374: warning: braces around scalar initializer
//374: warning: (near initialization for `veriusertfs[0]')
//374: `usertask' undeclared here (not in a function)
//374: initializer element is not constant
//374: (near initialization for `veriusertfs[0]')
//374: warning: excess elements in scalar initializer
//374: warning: (near initialization for `veriusertfs[0]')
//374: warning: excess elements in scalar initializer
...
...

All the include files are exist, what I'm missing?? are the include files too old??

Thanks, Benni.

  • Thank you I forgot to inclode "vxl_veriuser.h".
    Now the C file is compiled but I don't know how to do the link to C function, my C file is:

    int myfopen()
    //myfopen("./filename",FILE *stream),return 0;
    {
    char *filename;
    FILE *fp;

    acc_initialize();
    //filename = (char*)(int)acc_fetch_tfarg(1);
    filename = tf_getcstringp(1);
    fp = fopen(filename, "r" );
    if(fp)
    {
    tf_putp(2, (int)(fp));//return the fp
    acc_close();
    if(DEBUG) io_printf("open the %s success!\n",filename);
    tf_putp(ARG_RET, true); //return the true
    }
    else
    {
    acc_close();
    if(DEBUG) io_printf("open the %s fail!\n",filename);
    tf_putp(ARG_RET, false);
    }
    return 0;
    }

    my SV code for using the C file is:
    initial
    begin
    integer fp;
    $myfopen("./script.txt",fp);
    ....
    end

    I tried to use the DPI-C declaration as the followin:
    import "DPI-C" function myfopen(input char filename, output integer FILE);
    import "DPI-C" function myfopen(input char "./script.txt", output integer FILE);
    import "DPI-C" context function myfopen(input char "./script.txt", output integer FILE);
    import "DPI-C" function int myfopen();

    and more but I have some cpmpilation error.
    Do you have any idea what I should do?

    Thanks in advanced, Benni.
