Eclipse Luno does not load after linking with Opencl Code Builder

I am using Centos 7 to use Opencl Code Builder. I have already downloaded and installed Intel Media Server Studio for Centos 7 OS. To start programming with Opencl, I use Eclipse Luno (Eclipse for Parallel Application Developers version) and the Eclipse IDE is loaded properly. To link with Code Builder, I followed the discussion here. The instructions are

To enable the OpenCL™ API Offline Compiler plug-in for Eclipse* IDE, do the following:

  1. Copy the plug-in *.jar file from $(INTELOCLSDKROOT)\bin\eclipse-plug-in to $(ECLIPSEROOT)\dropins.
  2. On Linux* OS add $(INTELOCLSDKROOT)\bin to LD_LIBRARY_PATH.
  3. Run Eclipse IDE.
  4. Select Window > Preferences.
  5. Switch to the Intel OpenCL dialog and set OpenCL binary directory$(INTELOCLSDKROOT)\bin\. I have already finished 1 and 2. But when I run Eclipse IDE, I have error and IDE stop loading in halfway. The error is "Cannot get machine list. Could not load required libraries. Please make sure to set the correct path under the Code Builder for Opencl preference page". What is wrong with that error? Thanks

I am seeing this behavior too with the latest release.  Hoping to gather more info on complete setup steps and get back to you.

It looks like your OpenCL setup is fine, so you can hopefully proceed with command line.

Thank you so mushc,but, i encounter the same trouble "the error dialog box appeared and I pressed OK,and the  IDE is not loaded and stop loading after that". 

Please let me know what's the else  info you need?

On the other hand,I will try the command line mode.

Thank you.

Hi,Jeffrey

When i try to build the test code as below:

Deleted non public test code submitted by user. *MichaelC 20180724*
 

The ioc64 reports the "Failed to build program...: -11 (CL_BUILD_PROGRAM_FAILURE)"

When i use the command :ioc64 -input=library.cpp -device=gpu

No command specified, using 'build' as default
1 error generated.
OpenCL Intel(R) Graphics device was found!
Device name: Intel(R) HD Graphics
Device version: OpenCL 1.2

Device profile: FULL_PROFILE
/home/sam/CLionProjects/untitled/library.cpp:8:10: fatal error: 'cl.h' file not found

Failed to build program...: -11 (CL_BUILD_PROGRAM_FAILURE)
Build failed!

 

I think maybe i don't set a LD_LIBRARY_PATH cause that.So,i set it in /etc/enviroment as 

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/intel/opencl/SDK/bin"
#export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/x86_64-linux-gnu:/usr/lib64:/usr/local/lib
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/opt/intel/opencl:/usr/lib64:/usr/local/lib"

 

It also report the same log as upside.And,after i add the LD _LIBRARY_PATH line in /etc/environment , i use the command "sudo python sys_analyzer_linux.py -v" to check the system,it reports as below:

Could you help me fix it ?It will help me a lot!

Thanks

Hi Sir,

1) I can implement well at step [1] and [2]  but when I run step [3], there are happen same issue as previous question

     to have error prompt message as below  during start Eclipse.

     "Cannot get machine list. Could not load required libraries. Please make sure to set the correct path under the Code Builder for Opencl preference page"

2)I make sure to have right setting in LD_LIBRARY_PATH and "libKernelBuilderAPI.so" is exist in folder "/etc/alternatives/opencl-intel-tools/lib64".

3) user@user-SKLU-IE1:/etc/alternatives/opencl-intel-tools/lib64$ java -version

A couple of comments in an attempt to provide guidance for users encountering similar issues.

Erickson.LU's post:

ioc64 is for kernel sources, not host programs. In the post, the  host side C++ application is sent through ioc64. This will fail as ioc64 is not a C++ compiler. Use your host compiler (i.e. cl.exe /TC or cl.exe /TP from msvs, icl.exe /TC or icl.exe /TP from Intel... gcc/g++ from GNU, icc/icpc) for your host program.

 

Bill Sung's post:

The codebuilder interface attempts to see dependencies that aren't immediately available on some newer linux distros... See the prerequisites at the gsg page. Take a look at https://software.intel.com/en-us/articles/sdk-for-opencl-gsg:

Step 2: Install the Intel SDK for OpenCL Applications

  • Install oracle-java8-installer
  • Install mono
  • Install the appropriate libicu version (for Intel® Code Builder for OpenCL™ API plugin support)
  • Install dkms and lsb-core for driver support
  • Note: Update tools need to go out to the web. If your system requires a proxy for the web, make sure your environment variables are visible as root user.

libicu tends to be the missing dependency... see the example linked on the page for a suggestion of obtaining it:

curl -O http://launchpadlibrarian.net/201330288/libicu52_52.1-8_amd64.deb
dpkg -i libicu52_52.1-8_amd64.deb

We'll look to create new bringup guidelines for subsequent releases of the SDK.
