OpenCL bitstream unsigning crashes - Arria 10 PAC Card

[Saikiranbelana]

Hi, I was trying to unsign the compiled aocx file. It crashes by this error:

fpga@fpgaserver2:~/A10_OPENCL/vector_add/bin$ source /home/fpga/inteldevstack/a10_gx_pac_ias_1_2_1_pv/opencl/opencl_bsp/linux64/libexec/sign_aocx.sh -H openssl_manager -i vector_add.aocx -r NULL -k NULL -o vector_add_unsigned.aocx 
The script assumes the PACsign and Intel Acceleration Stack environment is setup. If not run the command : <stack_installation_path>/init_env.sh
hsm_manager=openssl_manager
aocx filename/path=vector_add.aocx

csk_public_key=NULL
output filename/path=vector_add_unsigned.aocx
null=1
openssl hsm_manager_options=openssl_manager

output path =.
output filename =vector_add_unsigned.aocx

For RedHat-based distros, install package openssl-devel.
For Debian-based distros, install package libssl-dev.

I have installed `libssl-dev` and it still causes the same error. I have edited ldconfig to add `libcrypto.so` library too. 

Is there something I'm missing with openssl installation ?

Hi,

Did you happen to install openssl-devel package? please check

I am working on this issue and please share the log file. it helps to duplicate the issue.

Thank you,

Hi Hareesh,

here's my log for OpenSSL and libcrypto

fpga@fpgaserver2:~$ cat /etc/ld.so.conf.d/mylib.conf 
/usr/lib/x86_64-linux-gnu/libcrypto.so.1.1
fpga@fpgaserver2:~$ ldconfig -p | grep libcrypto
        libcrypto.so.1.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1
        libcrypto.so.1.0.0 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0
        libcrypto.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libcrypto.so
fpga@fpgaserver2:~$ openssl version
OpenSSL 1.1.1  11 Sep 2018

I have installed `libssl-dev` package and configured `ldconfig`. 

Thanks & Regards,

Hi @hareesh ,

Please find the attached zip file for vector addition that using for compilation using Inteldevstack. We are using Arria 10 PAC Card.

The compilation takes a long time and is successful but while unsigning the `aocx` file, the terminal session crashes with the error:

Error: Module: openssl.py, Function: __init__, Line: 332
       Failed to find crypto library (libcrypto.so).

please can you suggest a solution to fix the error?

Thank you,

Hi,

-because of my workload, I am taking time. sorry for delaying

[hareesh]

Hi,

sorry for delaying. I am also facing some issues at compile time. I am discoursing with the team mostly today or tomorrow I will try to respond to you with the solution.

[hareesh]

Hi,

sorry I was taken a long time.

 We suspect there might be some issues with the environment setup.. the reason why it's complaining of missing library after some checking.. would recommend you try to initialize the open for acceleration stack and try the compilation again.

https://www.intel.com/content/www/us/en/docs/programmable/683831/1-2-1/initializing-the-environment-for-with.html

above is some quick guide for the mention initialization.
