Run the DOS prompt as administrator Run the init.hls.bat Compile the file from the SAME DOS prompt...i.e. don't close the DOS prompt. Re-run the init_hls.bat every time. Regards Konrad Re: hls installation and getting started Screen shot of the init_hls.bat ps. I also have quartus 19.1 installed on my C:\ drive in the standard location...I opened and closed it prior to running to ensure it was the last version run, but the init_hls.bat seems to still pick up on the older version, Regards Konrad Re: hls installation and getting started Hi, I have VS 2010 Pro available at work but not at home. I have installed HLS 21.2 PRO. Does this need a license or is it OK with Quartus Lite? From what I have read it seems the HLS Pro is OK without Quartus Pro. Anyway, when I run the tools they are still pointing to the HLS 19.1 compiler. The init_ .bat ran OK. regards Konrad Re: hls installation and getting started I do not know how to set the Visual Studio environment. Visual studio is on my C:\ drive as a standard install (comunity free version) C:\Program Files (x86)\Microsoft Visual Studio\2017\Community Regards Konrad Re: hls installation and getting started The installation had left all folders as read-only and I reset them to full access read/write. I now have a compile error:- Regards Konrad Re: hls installation and getting started But as you can see from the second screen shot it is not working, the compiler comes up with permission errors. Something is not set up correctly, regards Konrad Re: hls installation and getting started ooops...administrator rights. I am trying to learn this at home. At work I have a 4 year old project I did in Altium that needs updating. This is mostly VHDL with some Altera IP FIR filters, but uses the Altium c to hardware compiler to do floating point math. The math is just float multiply/divides for a fast ARC2TAN. This worked great with Altium, but they no longer support FPGA development. regards Konrad Re: hls installation and getting started I get the following when trying an example, this is my home computer where I have full administor rights, Windows 10 Re: hls installation and getting started Re: hls installation and getting started btw, D:\Altera\ is where an older copy of Quartus is installed, 😧 being a hard drive. C:\Program Files (x86)\Microsoft Visual Studio\2017\Community is where Visual Studio is
