oneAPI on DevCloud fails on building for FPGAs

Hi,

I have access to Intel DevCloud to try oneAPI. and I use `qsub -I` to open interactive terminal

I tried to make FPGA examples from BaseKit-code-samples , but `make fpga` shows an error

```

[ 50%] Linking CXX executable ../triangular_loop.fpga

aoc: Quartus is not on the path!

aoc: Is it installed on your system and quartus bin directory added to PATH environment variable?

/home/u34315/tmp/triangular_loop-a503a1.o: file not recognized: File truncated

clang++: error: fpga compiler command failed with exit code 1 (use -v to see invocation)

clang++: error: linker command failed with exit code 1 (use -v to see invocation)

make[2]: *** [src/CMakeFiles/triangular_loop.fpga.dir/all] Error 2

make[1]: *** [src/CMakeFiles/fpga.dir/rule] Error 2

Makefile:183: recipe for target 'fpga' failed

make: *** [fpga] Error 2

```

If I source

init_opencl.sh

from different pre-installed quartus version I get version incompatibility error.

Could you please tell me which script should I source exactly to be able to use installed PAC on the DevCloud?

Also `aocl diagnose all` shows this message:

Hi,
I have try to run compile the with FPGA emulator and hardware with the command as below:
ssh decloud
git clone https://github.com/intel/BaseKit-code-samples.git
qsub -I -l nodes=1:fpga:ppn=2 -d .
cd BaseKit-code-samples/DPC++Compiler/vector-add/
vi build_fpga_emu.sh
#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
make fpga_emu -f Makefile.fpga
vi run_fpga_emu.sh
#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
make run_emu -f Makefile.fpga
vi build_fpga_hw.sh
#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
make hw -f Makefile.fpga
vi run_fpga_hw.sh
#!/bin/bash
source /opt/intel/inteloneapi/setvars.sh
make run_hw -f Makefile.fpga
qsub -I -l nodes=1:fpga:ppn=2 -d . build_fpga_emu.sh
qsub -I -l nodes=1:fpga:ppn=2 -d . run_fpga_emu.sh
qsub -I -l nodes=1:fpga:ppn=2 -d . build_fpga_hw.sh
qsub -I -l nodes=1:fpga:ppn=2 -d . run_fpga_hw.sh

I have saw the output is success by using command "cat".
I will check internally with the related information again.
Thanks

  In this scripts I see how you assign a particular node on devcloud for FPGA execution. Apparently not all nodes on the devcloud have FPGA hardware and required tools, you assign nodes with fpga property:
  qsub -I -l nodes=1:fpga:ppn=2 -d .
  I rewrote my scripts modifying qsub as above .
  I can compile and run applications on devcloud FPGAs now.
  Thank you.

Hi,
I am glad that the script can help you out from the problem.

Hi,
May I know which link you are referring?
Also, I would like to know which toolkit you are using on DevCloud?
Can you list flow and command you have used?
Thanks

Hi,
According to https://www.intel.com/content/www/us/en/programmable/products/boards_and_kits/dev-kits/altera/acceleration-card-arria-10-gx/getting-started.html, Intel PAC with Arria 10GX FPGA have used v17.1.1 BSP.
I have to check internally about the version used in DevCloud.
Thanks

@MeiYanL_Intel
Yes, there is written:
Intel Quartus Prime Pro Edition Software Version: 17.1.1
Open Programmable Acceleration Engine (OPAE) Version: 1.1.2-1
it seems devCloud FPGA toolkits are wrongly installed. and I don't have sudo access to regenerate the OpenCL BSP for newer versions of quartus. So probably another minor version of quartus 17 (maybe 17.1.1) is able to get along with opencl FPGA SDK .
Also it seems at least in my case OPAE is not installed.
Could you please let me know when the issue is resolved?
