How to Compile A Program ?

[IBNU1]

Hi,
I'm trying to compile a program using your interface by running the GCC compiler on it and I keep getting this list of errors that i'm not really sure how to solve. What instructions and options do I need to configure with my compiler in order to get software properly with this frame work ?

Hi @IBNU1

Can you share the steps you have followed to reproduce the issue?

Cheers,
Leon

[IBNU1]

Sure @lleon95 , I followed the standard installation instructions and ran the example program from the buildir which ran fan. Then in a seperate directory under root I typed up this code to use my own IP. All of this was being done on a Kria Kv260 board.

`#include <cynq/cynq.hpp>
#include <cstdint>
#include <cynq/accelerator.hpp>
#include <cynq/datamover.hpp>
#include <cynq/hardware.hpp>
#include <cynq/memory.hpp>
#include <iostream>
#include <memory>
#include <string>


// Configure the FPGA
int main(){
using namespace cynq;
auto kArch = HardwareArchitecture::UltraScale;
auto platform = IHardware::Create(kArch, "euler_test.bit");
int x1 = 1;
int y1 = 2;
int x2 = 4;
int y2 = 5;
// Extract the accelerator (IP Core) and DMA
// Addresses are given by the design
const uint64_t accel_addr = 0xb0000000; //get this value from the the Vivado program
auto accel = platform->GetAccelerator(accel_addr);
int test_output = 0;
printf("The Value of the output data is %d",test_output);
return 0;
}
`

I then tried to compile this code by entering GCC test.cpp and it returned me the above error.

[lleon95]

Alright,

Are you compiling it using?

g++ -o test test.cpp `pkg-config --cflags --libs cynq`

the pkg-config --cflags --libs cynq captures all the flags required for linking. It usually adds: -lcynq

[IBNU1]

Thanks so much, got it working.

[lleon95]

Perfect :) Glad it worked.
