Running on Linux

[PlutoIsBlack]

I am trying to run this on linux without a Pi can you please help me with how to compile this I am really new to Linux and think I am making some mistake.

[crescentvenus]

I think you should try original gps-sdr-sim, if you haven't tried yet. https://github.com/osqzss/gps-sdr-sim

[PlutoIsBlack]

I have tried it and works fine. I don't understand how you turn on the webui for extracting the lat. longs

[crescentvenus]

Original gps-sdr-sim has -l option which reads static Lat/Lon from command line. I modified the code to read Lat/Lon from a file when you specify a file name instead of static Lat/Lon.

[PlutoIsBlack]

I understand the concept but am unable to open the web ui

[PlutoIsBlack]

can you tell me how to open the web ui

[crescentvenus]

You need to have WWW server such as apache2 on the same PC running modified gps-sdr-sim and hackrf-transfer. And follow https://github.com/crescentvenus/WALB/tree/master/webui

[PlutoIsBlack]

ok thanks i will try and let you know

[PlutoIsBlack]

I configured everything like it said in the link but which file do I run to start the webui

[crescentvenus]

Just access the WWW server you set up using browser chrome. http://ip-youre-WWW-server/LatLon.php

[PlutoIsBlack]

I access it but the ui doesn't open instead it just shows text

[PlutoIsBlack]

if it isn't too much trouble could you please list the steps I should follow to get it working I added the API and updated the directories but still nothing

[crescentvenus]

Have you installed php ?

[PlutoIsBlack]

I got the map to work and ran the simulation but now for some reason it does not use the interactive mode just shows static mode and transmits some weird location

[PlutoIsBlack]

The latlon.txt is not being generated

[crescentvenus]

Well, it may file's permission issue. Can you send me directory list of WWW server. ls -l

[PlutoIsBlack]

really sorry but I don't know how to do it

[crescentvenus]

'ls -l' is one of the basic Linux command. On terminal , type something like "ls -l /var/www/html" .

[PlutoIsBlack]

Here is the list

[crescentvenus]

You have to get administrator authority, '$ sudo -s' Then, '# chown www-data:www-data /var/www/html/webui/*'

[PlutoIsBlack]

still nothing, I can't find any place where LatLong.txt is being created

[crescentvenus]

Check content of LatLon.ini.php.

[PlutoIsBlack]

LatLon.ini.php says that the file is in \tmp but there was no file there

[PlutoIsBlack]

Till now I have setup the server and map is working fine but the lat longs are not being saved

[crescentvenus]

When you click somewhere in the map, the center of the map changes accordingly ?

[PlutoIsBlack]

yes the center moves and marker is placed

[crescentvenus]

How about /var/www/html/webui/LatLon.txt ? It should contain Lat/Lon where you clicked and update every time you clicked.

[PlutoIsBlack]

there is no LatLon.txt file

[crescentvenus]

You can check WWW server log in /var/log/apache2/error.log Is there any error message in that file ?

[PlutoIsBlack]

There are a few error messages

[crescentvenus]

As far as I can tell from error.log, you installed related files in /var/www/html/ but not /var/www/html/webui/. Is that correct ? The 4th line of error.log tells it failed because lack of permission.

[PlutoIsBlack]

How do I give more permission and also now the map has stopped loading

[crescentvenus]

Tell me first, where is the installed directory ?

[PlutoIsBlack]

/var/www/html/webui/

[crescentvenus]

It is odd. error.log is pointing /var/www/html/LatLon.txt.

[PlutoIsBlack]

how was I suppose to install directory?

[crescentvenus]

Install directory does not matter. It must be just consistent through installation and operation. Can you show the result of "ls -l /var/www/html "

[PlutoIsBlack]

also now map is not initializing properly

[PlutoIsBlack]

[crescentvenus]

Well, I suggest you find nearby friend who can figure out the meaning of error.log. The error.log is telling couple of other errors too . Anyway, thank you for your interest of WALB project.

[PlutoIsBlack]

Thanks for all the help

[PlutoIsBlack]

one last thing can you show me a picture of LatLon.txt I would like to see how the data is presented in the file

[crescentvenus]

I will post again if something I came up with.

[crescentvenus]

LatLon.txx is one line simple TEXT file something like below. 45.79737,130.44659,100

[PlutoIsBlack]

LatLon.txt is updating successfully now Thank You so much

[PlutoIsBlack]

now which gps-sim-sdr should I run gps-sdr-sim or gps-sdr-sim_x64

[crescentvenus]

gps-sim-sdr is for raspberry Pi, gps-sdr-sim_x64 is for intel x64 processor.

[PlutoIsBlack]

In the video when you run it gps-sdr-sim it says interactive mode but when I do it, it says static mode

[PlutoIsBlack]

and also how do you start compiling and transmission simultaneously

[crescentvenus]

Naming has history. Is been more than 3 years from initial post. I added interactive function on static location mode of original gps-sdr-sim. I don't understand your question "how do you start compiling and transmission simultaneously" .

[PlutoIsBlack]

or are you transmitting it through GNURadio?
