Intel HLS not working with HLS/ac_int.h

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.
