Google map navigation GUI on Raspberry Pi 4

npatil15 · 24 Jun 2020, 04:50

Hello Everyone,

I want to implement google map navigation GUI on Raspberry Pi.

Here I have some options which are known and having expertise to me for implementation like:

Python with Qt
CPP with Qt
Python with Tkinter or any other GUI support library

I have googled some of those and run example codes in windows 10 for understanding its performance, but even if on windows 10 having 32 GB RAM(edited), on running code it showing LLVM out of memory.

So I didn't understand how I can start with this?

Please provide your suggestions.

Thanks.

I don't think it is about your hard disk, it is RAM. Or do you mean RAM instead of "hard disk"?
Do you get this error when compiling project?
Why do you use LLVM?
Which Qt version?

Sorry its typing mistake, its RAM actually.
QT details:
Qt Creator 4.5.0
Based on Qt 5.9.4 (MSVC 2015, 32 bit)

And I dont know about LLVM, where we select it to use it?

@npatil15 I'm not interested in QtCreator version, the question was which Qt version you are using (not QtCreator). So, which Qt version and compiler do you use? Which Qt examples do you try to build?

npatil15 · 24 Jun 2020, 05:13

Qt version: 5.9.4
Tried examples like, mapviewer, logfilepositionsource, places_map
Compiler: Qt 5.9.4 MSVC2015 64 bit, also tried MSVC2017 64 bit

@npatil15 When exactly does this LLVM error occur?
Why do you use such an old Qt version?
Try with the current one.

As soon as I click run, it waits and gives LLVM error.
And the latest Qt version is 5.15, but if the version looks issue then I can try with a new one.

But does the project build or not?

npatil15 · 24 Jun 2020, 06:07

Project build successfully, its run time error

@npatil15 Did you check memory consumption of the app?

Checked memory consumption in Task manager, there is shows RAM usage of 1.6 mb only.
