./pac_hssi_e10: error while loading shared libraries: fpga_hssi.so: cannot open shared object file: No such file or directory when I was following the 10Gbps Ethernet Accelerator Functional Unit Design Example user guide

Dear Sir/Madam,

I am having a software error issue when I was running the example based on the 10Gbps Ethernet Accelerator Functional Unit Design Example user guide.

error was this

./pac_hssi_e10: error while loading shared libraries: fpga_hssi.so: cannot open shared object file: No such file or directory.

I just list what I have done here ,any suggestion is welcome.

There are two PAC CARD inserted in my server

You have new mail in /var/spool/mail/root

Check further information including Pr Interface Id and BMC version

Check hssi information as needed as below

root@fig01 sw]# ls /sys/class/fpga

intel-fpga-dev.0 intel-fpga-dev.1

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.0/

device intel-fpga-fme.0 intel-fpga-port.0 power subsystem uevent

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.0/intel-fpga-fme.0/

altr-asmip2.0.auto bitstream_id cache_size dperf emif_mgmt fpga_manager modalias power revision subsystem uevent

avmmi-bmc.2.auto bitstream_metadata dev driver errors intel-pac-hssi.1.auto ports_num pr socket_id thermal_mgmt version

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.1/

device intel-fpga-fme.1 intel-fpga-port.1 power subsystem uevent

[root@fig01 sw]# ls /sys/class/fpga/intel-fpga-dev.1/intel-fpga-fme.1/

avmmi-bmc.5.auto bitstream_metadata dev driver errors intel-pac-hssi.4.auto ports_num pr socket_id thermal_mgmt version

So we can summary as below

PAC Card 0

3B:00:00

intel-fpga-dev.0

intel-fpga-fme.0

intel-fpga-port.0

intel-pac-hssi.1.auto

PAC Card 1

D8:00:00

intel-fpga-dev.1

intel-fpga-fme.1

intel-fpga-port.1

intel-pac-hssi.4.auto

and further operation will based on above information.

[root@fig01 eth_e2e_e10]# cd sw

[root@fig01 sw]# make

make: Nothing to be done for 'all'.

the reason was I have done make before, but I can confirm relavant files was generated as below

[root@fig01 sw]# sudo sh -c "echo 10 > /sys/class/fpga/intel-fpga-dev.1/intel-fpga-fme.1/intel-pac-hssi.4.auto/hssi_mgmt/config"

./pac_hssi_e10: error while loading shared libraries: fpga_hssi.so: cannot open shared object file: No such file or directory

[root@fig01 sw]#

would you please any other test I can try?

thanks
