HLS compilation issues

[Liyen]

Hello,

    I installed Quartus Lite 18.1 and came with HLS compiler 18, I tried to

compile the QRD example but encountered following build errors, I think

these are related to incompatible glibc version used to build HLS i++  and

the one installed on my system, could you please advise how to work

around such problems? much appreciate for support

g++ --version

Hi @Liyen

Thank you for posting in Intel community forum and hope all is well.

Suspecting as per mention the gcc seems to be incompatible version, recommende version of gcc for version 18 is 4.4.7.

Hence would suggestion to reinstall the correct gcc version by following the instruction in the link below:

- https://cdrdv2-public.intel.com/705011/ug-hls-getting-started-18-1-1-683680-705011.pdf

Hope that clarify.

Best Wishes

Hi Boon,

    much appreciate for responding to my questions, in fact, per wonderful know-how folks who were so nice to describe their kindness, these issues are all cleared but left some intrinsic GUI issues of modelsim which

were known decades ago, perhaps they didn't think that matter, this is okay.

     the problem is still strange, that why modelsim looks into a directory under root, / , which wasn't installed

by modelsim starter edition installer, for all the required packages? but it behaved properly after clean up

several issues of init, config files under my personal home. thank you very much for all endeavors.

     To be honest to you, the reason I dived into intel FPGA device development was for, complex project work

like open-cv, gnu-radio, and adas/ ai types, I'd believe besides intrinsic HDL works, there are also critical HLS

development, but I don't find something like xf-opencv from xilinx that was offered by altera/intel? I wonder

if you could advise some professional (open source is preferred) HLS project works based upon altera/intel

FPGA development packages? thank you

HI Boon,

   Much appreciate for the advice, it did solve my problem to launch i++, however, I immediately ran into

another issue with, this time, Modelsim starter edition, below is the error prompted either I ran in the

terminal or thru Quartus interface, I understood these were emitted from libtcl, the issue is that

/mtitcl/vsim wasn't part of Modelsim_ase setup during Quartus installation, and I don't see how/where

I can modify this path to lead to correct location (I found pkgIndex.tcl provided uch info), could you

please help me on this one as well? much appreciate

linux$ vsim

Error in startup script: can't find package Msg
   while executing
"package require Msg"
   invoked from within
"ncFyP12 -+"
   (file "/mtitcl/vsim/vsim" line 1)

Hi @Liyen,

Good to know that you managed to run i++ now.

As for the modelsim issues, to check you have installed modelsim starter edition you mention?

And based on the error it seems like a missing files/library, and you mention you are able to find the required files and modify the path accordingly?

Does that help on fixing the issues?

Hi @Liyen,

Good to know that the complier gcc version issues has been fixed.

For the modelsim issues we do have a better experiences team supporting that as link below:

- https://community.intel.com/t5/Intel-FPGA-Software-Installation/bd-p/fpga-software-installation-licensing

Perhaps if you can provide more details on the errors and logs that would be better for us to dig deeper into the strange issues.

As for the example project for HLS, upon installation there will be included in the following path below:

- <quartus_installdir>/hls/examples/<design_example_name>

Hope that clarify
