How to get candle or grblcontrol installed in raspberrypi

[jvarl]

Hi, in previous post (see #55) I was trying grblcontrol over different pc's. Also I tried to install this friendly program on my raspberry pi without success (see #72).

This time I announce that finally my efforts were crowned with success. I have installed grblcontrol and Candle in my raspi-3b raspbian on two different images, one in the traditional Jessie (2016-05-27-raspbian-jessie.zip image) and another in the new jessie PIXEL. In both cases I used micros-sd memory of 16GB Class 10.

I want to provide information about steps I walked for people interested in getting it and do not know how to achieve it:

• I made an installation of libraries QT5 by native compilation of sources from the git repository cloned on raspbian (to compile source code Denvi, qt5.4 or higher is required). I rely on recommendations found in the QT wiki post “Native Build of Qt5 on a Raspberry Pi”. In my case, obtain QT5 libraries compiled from source required a time of 8 hours in the raspi-3b (mentioned article refers 2 days?). While I followed meticulously and carefully the steps there, trying not to make mistakes, I needed to modify the data about type and amount of binary packages that I installed, because from 56 packages given there only 15 I used to make my 203 proper packages installed, based on tests I did. Do not use the package list in the post nor did the patch give there. Only use “my-package-list”, “sudo apt-get install ”, then “sudo apt-get update”, “sudo apt-get upgrade”.
• Following I give “my-package-list” to install previous to clonate git qt5 sources, init-repository… , configure…, make…, sudo make install… etc.etc.

Pay attention for changes to introduce in files there mentioned. Use “copy-paste” for text on the post and edit every line in your preferred text editor previously to paste it in the terminal command line to be executed. Pay attention using “sudo” were needed and change use permissions for private files.

If you intend compile Candle in qt-creator you must fix two present errors in the source code gave at present as .zip file:

• In frmmain.h you must append the following line:

#include <QGLFormat>

• and in qlwidget.cpp you must append:

#define GL_PROGRAM_POINT_SIZE 100

If it were of interest to get a raspbian image with qt5.7.1 libraries installed and grblcontrol and Candle, please give me to know and I will introduce a link to download (dropbox or google drive). Best regards. JVARL

Has anyone had success installing this on a Raspberry Pi 5? I've tried the pre-built installs and also building from source following the wiki pictorials. The release does run using './Candle2', but the visualizer panel is empty and you see the desktop behind the window through it. I've used the mesa override to get other software to run on the pi5 so I tried: 'sudo MESA_GL_VERSION_OVERRIDE=3.3 ./Candle2' It runs, and now the visualizer is black, but you don't see any USC icon or anything, unlike the post above. Nothing but black when loading a project or changing the colours in settings. Any thoughts? Thanks very much.

@ddllpp Have a look at the forked v1.1.9 release with 64-bit Candle-1.1.9-RPi-aarch64.AppImage and 32-bit Candle-1.1.9-RPi-armhf.AppImage.
