OpenCL bitstream unsigning crashes - Arria 10 PAC Card

Question

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 : &lt;stack_installation_path&gt;/init_env.sh
hsm_manager=openssl_manager
aocx filename/path=vector_add.aocx
root_public_key=NULL
csk_public_key=NULL
output filename/path=vector_add_unsigned.aocx
null=1
openssl hsm_manager_options=openssl_manager 
input path =.
input filename =vector_add.aocx
output path =.
output filename =vector_add_unsigned.aocx
Extracted the filename as vector_add_unsigned 
1. Extracted the bin from the aocx 
2. Extracted the gzip compressed GBS file from the .bin
gzip: temp_vector_add_unsigned.gbs already exists; do you wish to overwrite (y or n)? y
3. Uncompressed .gz it to get the GBS file
Initiating PACSign tool to sign the GBS. This process will take a couple of minutes...
Creating unsigned aocx file by signing a NULL key

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

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 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) =&gt; /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1
        libcrypto.so.1.0.0 (libc6,x86-64) =&gt; /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0
        libcrypto.so (libc6,x86-64) =&gt; /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 &amp; 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?

Regards,
