Hello there,
I am currently trying to get into OpenCL Programming for FPGAs. I followed Intels "aocl_c5soc_getting_started" guide (I've got a DE10-Standard). I eventually got the emulation up and running, but i have huge probelms with the cross-compilation of the host aswell as the actual Kernel compilation. I compiled the Kernel with the environment Variables set as described in the guide. aoc -board=c5soc_sharedonly device/vector_add.cl -o bin/vector_add.aocx This command exited after around 30 minutes with 2 warnings and 0 errors. The Image which i downloaded from Terasic already contains a working kernel and executable so i tried to swap out their kernel with mine and it did no longer work. (At this point I was not able to compile the host so I thought to give the swap a try to verify wether the kernel is working correctly) So now onto the Host compiling problem. So i start by setting up the environment variables as before and ran make, which had a warning about libacl_emulator_kernel_rt.so missing. Now that i had the kernel and the host i tried running it on the FPGA and got error message ./host: error while loading shared libraries: libintel_soc32_mmd.so: cannot open
shared object file: No such file or directory I found this guide on Youtube https://www.youtube.com/watch?v=npeuaj-mfvy&index=3&list=rd4pukzi14mly and he switch into the embedded shell for compiling, but after doing so I only got another error Message stating arm-linux-gnueabihf-g++: error trying to exec 'cc1plus':
execvp: file or directory not found which is probably because the cc1plus in the path is a 32bit ELF. Further Information: I am Running in Ubuntu 16.04 and use IntelFPGA OpencSDK 18.0. The Board I use is the Terasic DE10-Standard (Cyclone 5 SoC) Environment Variables are set up as follows $ cat exports
export ALTERAOCLSDKROOT="/home/daniel/intelFPGA/18.0/hld"
export INTELFPGAOCLSDKROOT=$ALTERAOCLSDKROOT
export QUARTUS_ROOTDIR_OVERRIDE="/home/daniel/intelFPGA/18.0/quartus"

$ source exports Thanks and kind regards, Daniel.
