Intel Graphics Compiler Failed Build

[gija92]

Hello,

I want to use the Intel Compute Runtime for OpenCL and now installing the dependencies gmmlib and the igc. GmmLib was successful but igc return errors while make [-j'nproc'], that llvm::SmallSet and llvm::AttributeSet are not declared but acutally can be found in the "workspace"-directory.

I'm following the constructions but don't know how to solve the problem.

For more Details:
I am using an Minnowboard Max with Intel Atom E3825 CPU and already installed LLVM/Clang 4.0. before I build the IGC

Hope some of you guys can help me

Hi,

Can you give more details of your system (OS, gcc version etc.)?

[gija92]

@astojano sure ^^
OS: Linux Ubuntu 16.04 (created with yocto project)
GCC: version 6.4.0
LLVM/Clang: 4.0
CPU: Intel Atom E3825

Background: I want to set OpenCL driver for the Intel CPU and GPU for application which is based on OpenCL. Therfore the aim is to type command clinfo and see the CPU and GPU as OpenCL devices

Thanks

We'll try to reproduce and fix the problem, but for now we don't have your hardware so we focus on desktop PC.

Could you try to use previous version of GCC? We currently use GCC 5.4.0 on Ubuntu 16.04 in our CI system.

@astojano
alright I will give it a try.
Thanks :)

Does older version of GCC work for you?

I downloaded latest code, but couldn't reproduce the issue on my system with Ubuntu 18.04 LTS, gcc 7.3.0. Do you see SmallSet code in llvm_source?

@iwwu
I'm trying to re-install GCC 6.4..0 but failed so I now build a new Image with yocto and try it again.
I'm using a Yocto-Image for the Minnowboard with GCC 6.4.0.

Just to avoid misunderstandings. Am I right that I have to follow the steps directly on the minnowboard?
Or can I build the "workspace" in Ubuntu 16.04 (virtualbox). and create a binary which I can afterwards run on the board?

[astojano]

Give a try to older version of GCC like 5.4.0.

If you build a binary in appropriate architecture on virtual machine the binary should works fine on board.

@astojano
Thanks I will try it. :)

@gija92 Did this suggestion work. Can this issue be closed?

[gija92]

No unfortunately not. I installed a new ubuntu version instead of using a yocto image.
