66AK2H14: libOpenMPAcc.so.1 Not found when executing OpenMP ACC application

Part Number: 66AK2H14

Hi,

I just tried an OpenMP ACC example application on evmK2H, which it is bounded in the latest ProcSDK (Release 03.02.00).

I built OpenMP ACC examples with the following instructions:

cd <proc sdk top>
make openmpacc-examples_clean
make openmpacc-examples
make openmpacc-examples_install DESTDIR=<my nfs filesystem>

After booting linux on the target board (evmK2H), I executed the following command on the target.

cd /usr/share/ti/examples/openmpacc/printf_debug
./printf_debug

Then, I saw the following error:

./printf_debug: error while loading shared libraries: libOpenMPAcc.so.1: cannot open shared object file: No such file or directory

The same error is found on e2e. It looks like a verified answer, but here I could not find the exact answers about missing shared library.

Do you have any suggestions on this problem ?

Naoki

Hi Naoki,

I've forwarded this to the OpenMP experts. Their feedback should be posted here.

Hi,

In the mean time, verify that you have the OpenCL & OpenMPAcc packages installed. Check the following guides:
processors.wiki.ti.com/.../OpenMP_Accelerator_Model_0.3.3
processors.wiki.ti.com/.../OpenMP_Accelerator_Model_Getting_Started

Hi,

processors.wiki.ti.com/.../OpenMP_Accelerator_Model_Getting_Started

This says:
・Ensure the OpenCL package is installed and an OpenCL example has been built and tested
・Ensure the OpenMPAcc package is installed

As for OpenCL, the examples in <ProcSDK top>/example-applications/opencl-examples-1.1.11.0 run correctly on my setup.
On the second part, I'm not sure the exact step for installing OpenMPAcc package. My understanding here is there is no need for additional OpenMPAcc installation because we have one-stop SDK (ProcSDK) for development on K2H.

Best Regards,
Naoki

Hi Naoki,

The OpenMPAcc library should be in /usr/lib directory and /usr/lib/libOpenMPAcc.so.1 points at it, if you list the files (ls -lat) in the directory, how does it look like?

Garrett

Hello Garrett,

Thank you for your reply.

I could not find the library at usr/bin. The following command shows nothing.

cd /usr/lib
ls -lat | grep openmp

Please note the network filesystem I'm using is tisdk-server-rootfs-image-k2hk-evm delivered in ProcSDK Linux Release 03.02.00.

Naoki

So what is problem ? Is the problem no /usr/lib/libOpenMPAcc.so.1 in filesystem by default ? Or no additional installation for OpenMPAcc ?
I'm waiting for your reply.

Best Regards,
Naoki

Naoki,

The libOpenMPAcc.so.1 is in the 'extra' file system: tisdk-server-extra-rootfs-image-k2hk-evm.tar.xz, please switch to it accordingly.

Regards,

Garrett

Thanks, Garrett. The example worked now with that filesystem.
