libjSSC-2.8_armsf.so no such a file
Hi people.
Im getting this ERROR as mango starts up, my installation is on a Linux 3.10.104 with an armv7l:
com.infiniteautomation.mango.io.serial.SerialPortConfigException: /root/.jssc/linux/libjSSC-2.8_armsf.so: cannot open the shared file: No such a file
What is strange is the file it mentions is exactlly there!
Obviosly I cannot open any serial connection ... so
If anyone can provide some help on solving this issue would be grea!
Thanks
Hi fidelg,
It could be a permissions issue. Can you share the result of
ls -l /root/.jssc/linux/
and the user under which Mango is running?
Also check the armsf and armhf text closely. Is it really a soft float device? What's the platform?
Thanks 4 the reply, here u have:
root@odroid-jessie# ls -l /root/.jssc/linux/
total 11
-rw-r--r-- 1 root root 10779 mar 13 17:57 libjSSC-2.8_armsf.so
Im running the mango with the user: admin
And here the result of my lscpu
Architecture: armv7l
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
CPU max MHz: 1824.0000
CPU min MHz: 24.0000
The user "admin" is the user within Mango. I am wondering what the operating system user Mango is running under is.
I expect the answer to be root, because it is autodetecting the path into /root but root can definitely read the file so no permissions issue.
I don't think that's enough information to determine if it's really a hard float or a soft float, but we can be reasonably confident the correct architecture is being detected (edit: actually, I bet the jssc library copies the .so out of itself based on the jvm version, but I don't know) so this is probably just a curiousity. You can figure out that from the list of supported features for a processor core if you cat /proc/cpuinfo
Googling yeilded this thread:
It seems to suggest some people solved their issue by reinstalling java, and one purports to have snagged the armhf.so file out of the jssc jar, placing that into the .jssc/linux/ directory and that solved his problem.
To unzip a jar you can:
cd Mango/lib;
mkdir jssc;
cp jssc-* jssc;
cd jssc;
unzip jssc*;
#Files should now be in libs/linux/ if you need to grab them
