```

I've installed, and re-installed the tools, including Modelsim. I've tried starter and FPGA edition (no license though).

I've sourced init_hls.sh of course. Here is my PATH and LD_LIBRARY_PATH

```

LD_LIBRARY_PATH=/home/edhenderson/intelFPGA_pro/20.1/gcc/lib64:/home/edhenderson/intelFPGA_pro/20.1/hls/host/linux64/lib:/home/edhenderson/intelFPGA_pro/20.1/modelsim_ae/gcc-4.7.4-linux/lib

PATH=/home/edhenderson/intelFPGA_pro/20.1/modelsim_ase/bin:/home/edhenderson/intelFPGA_pro/20.1/qsys/bin:/home/edhenderson/intelFPGA_pro/20.1/gcc/bin:/home/edhenderson/intelFPGA_pro/20.1/hls/bin:/home/edhenderson/intelFPGA_pro/20.1/qsys/bin:/home/edhenderson/intelFPGA_pro/20.1/quartus/bin:/home/edhenderson/intelFPGA_pro/20.1/quartus/sopc_builder/bin:/home/edhenderson/bin:/home/edhenderson/bin/:/home/edhenderson/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

```

I've tried adding that last part of LD_LIBRARY_PATH: /home/edhenderson/intelFPGA_pro/20.1/modelsim_ae/gcc-4.7.4-linux/lib

but does not help or hurt.

Hi

Would like to know whether you were able to run the compile on any other version of HLS,

Can you try the same with 19.1 version also , so that we can rule out any version specific issues , and also rule out any issue with the setup.

Thanks and Regards

Anil

Hi ,

Please let us know whether by using 19.1 version of HLS this issue is resolved.

Thanks and Regards

Anil
