Freematics Hub for Linux is released

[stanley]

Binary for Ubuntu Linux x64 can be downloaded from https://freematics.com/hub

[cryptographrix]

Is it possible to make a public Docker image of this?

Hey guys,

thanks for this release. I'm trying to run the 32bit version on a raspberry pi 3 with Ubuntu Mate. (Also tried the 64bit version, but the OS is 32bit)
When i try to start by double clicking the "freematicshub" file (which it shows as an executable) nothing happens.

When I try running the the run.sh in the terminal like in the instruction:
$ sudo sh run.sh

i get an error like:

./electron/electron: 1: ./electron/electron: ELF



Ή4
�=4: not found
./electron/electron: 4: ./electron/electron: Syntax error: word unexpected (expecting ")")
./freematicshub: 1: ./freematicshub: Syntax error: word unexpected (expecting ")")


Any ideas?
Thank you in advance!

I'm also interested in a Raspi version

[HonkMcFunk]

Ok, I asked some "smart people" and they explained to me, that although the RasPi is running "Ubuntu" it's not the same (as the underlying architecture is completely different) and so the code for the "standard" Ubuntu won't be able to run.

(Silly me thought, that the OS will "abstract away" those architectural diferences )

Considering freematics HUB is open sourced under GPL license, is it possible to access the code for HUB somewhere ?

Happy New Year everyone,
I attempted to install FreematicsHub on my Ubuntu server, but was unsuccessful. Please help direct me to a resource to get me on track to setup the FreematicsHub on Ubuntu so that I can start using telelogger.

I downloaded and extracted the .zip file with the Freematics repository from GitHub. I did not find a .tar file for Ubuntu mentioned in the installation guide.

I attempted to follow the instructions for Linux https://blog.freematics.com/2018/freema ... ck-system/, but was unable to run or compile teleserver.c. I'm not experienced with compiling from source code, so this is likely a user error. I read the g++ --help, but please direct me to what I'm missing.
From the teleserver folder I used:

Code: Select all

g++ -o teleserver -I httpd -l httpd teleserver.c

It returned the following issues:

I also attempted to follow the screenshot listed under the "On Linux, please build from source code..." https://freematics.com/hub/. Using "sudo sh run.sh" returned the error: "sh: 0: Can't open run.sh" as the file run.sh does not exist in the teleserver folder.

Please let me know where I should turn to get the teleserver up and running. If you need any additional information to point me in the right direction, just let me know.

Thank you,

For anyone that is unfamiliar with compiling from source code and wants to install FreematicsHub for vehicle data logging:
1) Download FreematicsHub from the GitHub repository: https://github.com/stanleyhuangyc/Freematics

2) Extract the .zip file and "cd" into the teleserver folder

Code: Select all

cd teleserver

3) Build teleserver from the source code https://www.howtogeek.com/105413/how-to ... on-ubuntu/
was helpful.
It is very simple to compile FreematicsHub, from the teleserver folder.

Code: Select all

make

Code: Select all

sudo make install

That's all there was too it.

4) Continue with the instructions from Stanley: https://blog.freematics.com/2018/freema ... ck-system/

Code: Select all

./teleserver

Hopefully that saves someone from spending the six hours it took me to figure out how easy it is.
