Executing the binaries generated by the HCC-Example-Application Segfaults about hcc HOT 14 CLOSED

Are you running with

LD_LIBRARY_PATH=/opt/rocm/lib ./binary

And if not, could you try that?

Following on please post the

results of

ldd ./binary

If you have debug symbols please also post the stack trace.

Have a look at this #197

from hcc.

Hi,
Im trying to complie saxpy.cpp example (All HCC applications segfaults)
I have linked '--amdgpu-target=AMD:AMDGPU:8:0:1' in the complie options. Here are my env variables:

echo $PATH
/opt/rocm/bin:/opt/rocm/hcc/bin:/home/saa/bin:/home/saa/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
echo $LD_LIBRARY_PATH
/opt/rocm/lib ./saxpy

Results of ldd ./saxpy:

ldd ./saxpy
linux-vdso.so.1 => (0x00007fff64b89000)

There were no debugging symbols found to post the stack trace.
Let me know i have to provide further information.

Thank you

from hcc.

Your LD_LIBRARY_PATH should be set like this

export LD_LIBRARY_PATH="/opt/rocm/lib"

You appear to have included the binary in the export which I think makes the variable invalid. I have had numerous segfaults with the saxpy example, but it works for me at the moment when the LD_LIBRARY_PATH has visibility of the hsa-runtime(64).so

Can youi also do a

ls -l /opt/rocm/lib

just to confirm you have the hsa runtime library?

Thanks

from hcc.

So i just set export LD_LIBRARY_PATH=/opt/rocm/lib in my .bashrc file

echo $LD_LIBRARY_PATH
/opt/rocm/lib

./saxpy still segfaults.

I believe i do hsa runtime library!

Can you show me the entire command you used to compile the saxpy example?

And can you confirm that the symlink is valid for /opt/rocm/lib/libhsa-runtime64.so (I'm assuming it is but just to be sure)

from hcc.

i tried the below 2 ways to compile the saxpy example:

• hcc hcc-config --cxxflags --ldflags --amdgpu-target=AMD:AMDGPU:8:0:1 saxpy.cpp -o saxpy
• hcc hcc-config --cxxflags saxpy.cpp -c -o saxpy.cpp.o
  hcc hcc-config --ldflags --amdgpu-target=AMD:AMDGPU:8:0:1 saxpy.cpp.o -o saxpy

Also to confirm the symlink, i typed 'readlink -f /opt/rocm/lib/libhsa-runtime64.so' on the terminal and got the following result,

readlink -f /opt/rocm/lib/libhsa-runtime64.so
/opt/rocm/hsa/lib/libhsa-runtime64.so.1.1.1

from hcc.

PS: i did put hcc-config --cxxflags --ldflags , hcc-config --cxxflags , hcc-config --ldflags in between the two backticks.

from hcc.

Yeah I figured, for sake of sanity consider using the following in future ;)

hcc $(hcc-config --cxxflags --ldflags)

I'm stumped, if you're interested in compiling (I have outstanding issues currently preventing me) with debug symbols you can attempt to use the following script I have put together.

from hcc.

I compiled saxpy like so:

hcc $(hcc-config --cxxflags --ldflags) --amdgpu-target=AMD:AMDGPU:8:0:1 saxpy.cpp -o saxpy

executing ./saxpy is still segfaulting.
What am i missing?
I'm happy to provide any information regarding my system/environment.
Running the executable through gdb says i do not have any debug symbols.

You'll likely have to wait for one of the actual maintainers to respond, sorry.

Thanks @dekken.

Hi,
Sorry to say this, Merlin Falcon boards are not supported by ROCm yet. Please find relevant information here: https://radeonopencompute.github.io/install.html

@bhsomegowda will you pls help me to get some sample input and way to execute those ArrayBandwidth and HCFFT code because when i do it i am getting following error:

### HCC STATUS_CHECK Error: HSA_STATUS_ERROR_INCOMPATIBLE_ARGUMENTS (0x100d) at file:/home/scchan/code/github/hcc-roc-1.4.x/hcc/lib/hsa/mcwamp_hsa.cpp line:2511

and it is refering to a file which doesnt even exist on machine.
