SE05x - Got "Error: Library sssapisw not found" when trying to install ssscli

James1126 · ‎08-10-2022

Hi Team,

SE05x middelware was successule pre-compiled in my Linux PC (Yocto build); both libsssapisw.so and libsss_engine.so are generated. I am also able to run sample applicatoins ( se05x_xxx) on target machine (i.MX8:running Linux) without any issue.

- ibsssapisw.so and libsss_engine.so are installed in /usr/local/lib in target machine (iMX8)

- Sample applications are installed in /usr/local/bin in target mahcine (iMX8)

I am now managing to use ssscli tool to do more tests but got failure when installing it.

I refer to file:///Z:/build_vmxs5mainecu/tmp/work/aarch64-poky-linux/se05x/4.1.1-r0/simw-top/doc/pycli/doc/pre-... to install ssscli.

Here is my steps

1. I copy folder "pycli" under "simw-top" from my build machine to i.MX8

2. Also copy folder "tool" (including libsssapisw.so) to i.MX8

3. I put these two folders under same directory level. Let's say "/home/root"

4. Run command under "pycli/src"

root@vmxs5mainecu:~/pycli/src# python3 setup.py develop
os.name -->posix
os.environ[LD_LIBRARY_PATH]-->/home/root/tools:.
!!Error: Library sssapisw not found !! Build sssapisw first !!
root@vmxs5mainecu:~/pycli/src# pwd
/home/root/pycli/src
root@vmxs5mainecu:~/pycli/src# ls /home/root/tools/
README.txt libsssapisw.so vs2019Components.vsconfig
root@vmxs5mainecu:~/pycli/src#

I dump LD_LIBRARY_PATH and the path looks good. libsssapisw.so is in the correct location.

I also tried to modify setup.py. It seems .so file is not defined there. But it doesn't help.

else:
    data_files = [(tools_dir, ["libsssapisw.dll",
            "libsssapisw.dylib", "libsssapisw.so"]),]

Thanks.

Hi @James1126 ,

As far as I know, the lib of "libsssapisw.so" should be copied to /usr/local/lib by "make install" command, have you done that when you pre-compiled the MW in your Linux PC (Yocto build)? and have you run the command "ldconfig" after that?

and have you prepared the following steps before install ssscli tool?

Hope that helps,

Have a great day,
Kan

Hi Kan,

libsssapisw.so is correctly copied to "/usr/local/lib" in my target board (iMX8) and there is no problem to execute se05x_xxx sample applications. Also I've installed "func-timeout" module in iMX8.

My question is could I just copy folder "pycli" to iMX8 and install it?

In setup.py, it doesn't really search share lib from /usr/local/lib but folder tools.

tools_dir = os.path.abspath(os.path.dirname(__file__) \
    + os.sep + ".." \
    + os.sep + ".." \
    + os.sep + "tools")

But maybe I got it wrong there.

Hi @James1126 ,

I am wondering if you have built libsssapisw.so successfully , please kindly refer to the following for details.

The difference here is you native compiled sssapisw in Raspi. I cross-compiled it in my Linux PC.

Actually I tried to reproduce your issue here but no success. I have copied both tools and pycil folders into another path, e.g. , /home/pi/test, and tried to install ssscli there, it works anyway. Please kindly refer to the following for details.

BTW, have you run the command ldconfig after "make install"? Have you done it natively or during the cross-compiling? Please kindly clarify.

Hi Kan,

I manually "ldconfig /etc/local/lib" and it still fails to create ssscli.

libsssapisw.so seems to be correctly located.

root@iMX8:~/pycli/src# ldconfig -v

/usr/local/lib:
	libsssapisw.so -> libsssapisw.so
	libsss_engine.so -> libsss_engine.so

ld conf file looks good.

root@iMX8:~/pycli/src# cat /etc/ld.so.conf.d/se05x.conf 
/usr/local/lib

root@iMX8:~/pycli/src# ls ~/tools/
README.txt                 libsssapisw.so             vs2019Components.vsconfig

Is it possible to share your libsssapisw.so with us?

Have a great day,

Hi @James1126 ,

I just reproduced your issue by deleting libsssapisw.so in /usr/local/lib, not the one in tools folder, please kindly refer to the following for details.

root@imx6ulevk:~/se05x_mw_v04.02.00_20220701_151557/simw-top/pycli/src# rm /usr/local/lib/libsssapisw.so
root@imx6ulevk:~/se05x_mw_v04.02.00_20220701_151557/simw-top/pycli/src# python3 setup.py develop
Error: Library sssapisw not found !! Build sssapisw first !!

Please kindly check if it is your case.

Have a great day,
Kan

Hi Kan,

libsssapisw.so exists in /usr/local/lib.

root@iMX8:~/pycli/src# ls /usr/local/lib/
libsss_engine.so  libsssapisw.so

libsssapisw.so is attached for your reference.

Thanks.

Hi @James1126 ,

I just tried the lib from your side, the issue is still there, so I think the root cause is due to libsssapisw.so building, maybe you can try to build it natively and check if it makes a difference.

root@imx6ulevk:~# ls /usr/local/lib/ | grep libsss
libsss_engine.so
libsssapisw.so
root@imx6ulevk:~# ls /usr/local/lib/libsssapisw.so -la
-rw-r--r-- 1 root root 1760800 Jan 6 2022 /usr/local/lib/libsssapisw.so
root@imx6ulevk:~# cd se05x_mw_v04.02.00_20220701_151557/simw-top/pycli/src/
root@imx6ulevk:~/se05x_mw_v04.02.00_20220701_151557/simw-top/pycli/src# python3 setup.py develop
Error: Library sssapisw not found !! Build sssapisw first !!

Alternatively you may try the lib from my side as attached.

Have a great day,
Kan
