Installing Compiling Rovergauge on Linux (Mint i386)

[colin.h...@googlemail.com]

Hi

I've got a netbook that would be ideal to run Rovergauge on; I installed a Mint distribution on it for another use and have been trying to get Rovergauge installed.

Its an i386 architecture - I couldn't find an i386 compiled version on the Rovergauge page so I attempted to compile it from the source code.

I have (I think) successfully compiled the libcomm14cux library using the instructions on the github site. - Is there a way to test it?

I don't seem to be able to get the Rovergauge to compile though. I've installed cmake and I believe I have installed the Qt Software Development Kit which were both available as packages in the mint distribution.

I was following the same command steps as for libcomm14cux 

However when I try to compile it, the cmake command fails because it can't find qt5widgets

I'm kind of stuck here. I'm reasonably computer savvy but I wouldn't class myself as a Linux expert so I may be missing something obvious.

If there is another Linux distribution that people have used successfully with Rovergauge I'm quite happy to try that.

Output from cmake command below

Colin (H), I don’t think you need to use cmake. IIRC, you just need to run “qmake”, then “make”.

[colin.h...@googlemail.com]

Thanks

Do you know the command line?

I tried "qmake ."

but it returned 'error in project file'

Sorry, the build instructions are a bit out of date. I'll try to help:

Once you've built libcomm14cux, you should install the library and the read14cux/write14cux executables to the appropriate system directories by running "sudo make install". You should then be able to run "read14cux" from anywhere. When connected to an ECU, you can test it by doing something like reading one of the fuel maps:

read14cux /dev/ttyUSB0 0xC000 128

If that works, then change to the RoverGauge source directory. Create a subdirectory named something like "build" where CMake can put its files. Change into that directory and run "cmake .." to point it back up to the main source directory with CMakeLists.txt. Once this is done, you should make a Makefile that will build the RoverGauge executable.

Thanks Colin

I'll give that a try tonight. Forgive my ignorance - how do I 'make a Makefile that will build the RoverGauge executable.'?

Hi

OK I I downloaded a fresh copy of the zip file and unzipped it to my home directory. created a build folder then in terminal I changed to the build folder and ran the cmake .. command but it still fails complaining about the qt5widgets

This is the output from the cmake command
colin@colin-1015PX ~/rovergauge-0.7.6 $ mkdir build
colin@colin-1015PX ~/rovergauge-0.7.6 $ cd build
colin@colin-1015PX ~/rovergauge-0.7.6/build $ cmake ..

Hmm. I don't have to adjust any environment variables on my Ubuntu 15.04 machine for CMake to find Qt5. Are you sure that you have all the appropriate Qt5 packages installed? On my system, Qt5Core, Qt5Widgets, and Qt5Gui are all available individually. Check that you have something equivalent to the following packages installed:

libqt5core5
libqt5widgets5
libqt5gui5

If you have the required Qt packages, you may need to set one of the environment variables that CMake recommends, such as CMAKE_PREFIX_PATH. On my system, I think this would be /usr/lib/x86_64-linux-gnu/cmake/. (You would need a slightly different path depending on your system architecture.)

[colin.h...@googlemail.com]

Thanks Colin.

I've figured it out. I had all the packages you mentioned so I searched a bit harder for qt5 packages and although I had installed the SDK there was a package called qt5-default that wasn't installed which sets qt5 to be the default qt version. Once I did this the compilation was successful and I've now got a rovergauge program I can execute.

Will try it out tomorrow

All working thanks

Once I figured out that I needed to be in the dialout group to be able to read the usb port it started to work.

Steps I went through (to remind me if I need to reinstall)

User needs to be in the dialout group to access the usb port

setserial is useful for checking if you have access to the serial port (package needs to be installed)
