Intel HLS not working with HLS/ac_int.h

Altera_Forum · ‎03-07-2018

Hello, I am trying to get a simple program working, but I can't seem to compile it with i++.

I traced the error back to this include line. If I comment it, I have a hello world program working, but otherwise, it fails to compile.

# include "HLS/ac_int.h"

Here is the full code:

#include "HLS/stdio.h"# include "HLS/ac_int.h"
int main(void)
{
        printf("Hello World");
        return 0;
}

From the errors below, I would think that I am missing some header files, but I don't know which ones or where I can find these files. I am running in CentOS 7

I am running this command:

$ i++ -v -o test -march=x86-64 main.cpp

and receiving this output:

Target FPGA part name: 10AX115U1F45I1SG

Target FPGA family name: Arria 10

Target FPGA speed grade: -2

Any help would be appreciated.

Hi,

HLS Compiler not is supported on CentOS 7 may because of this you may get this error.

The code works fine on windows 10.
