[Gambas-user] Need help getting Gambas to run on an ARM module

[Bruce Cunningham]

I tried installing MonoDevelop today, and it works fine from the same repo.  I ran “apt-get install monodevelop” to install it.  So, it seems other packages in the repo are fine.  I’ve installed several other things from the same repo, and they are all fine.

It’s like the Gambas binaries are broken?  I don’t know who maintains the Gambas builds for the armhf architecture.

yoiur cpu its not mali, the real cpu for you are the https://en.wikipedia.org/wiki/ARM_Cortex-A7

here a table comparison https://en.wikipedia.org/wiki/Comparison_of_ARMv7-A_cores
now lets see the (unfortunatelly) wiki for that:

https://wiki.debian.org/InstallingDebianOn/Allwinner#Installing_on_systems_that_are_not_supported_out_of_the_box

ARMv7-A its the real cpu of you, but the all winner seems has issues on installer, your debian arch must be armhf that was released by firts time with wheeze
please are the debian arch flavor the armhf do you installed? do you used the correct device tree?
also i noted that gambas are not enought tested on arm platforms, inclusivelly in the bugtracker i can see that developers does not have hardware to test... so i think many bugs are still present for arm

Piccoro,

The device is like a Raspberry PI, but uses an Allwinner SOC instead of the Broadcom SOC.  The processor is an ARM Cortex A7 dual core with the Mali400 GPU.

Here is a link to the device:

I hope this helps.

apt-get install gambas3”.  It installs, but will not launch.  If I try to invoke it from the command line, it just hangs.  No error message, just hangs until I do ctrl-C.  I tried to build it from source, but encountered a number of errors, and never could get a full build.
in this case seems the arch are not the same.. please report the exact hardware you are in use, i remenber that in debian theres a new floavor ofr arm devices


So, I found a build of Armbian (xenial) with a GUI that seems to work very well for this board.  Much better OS build.  I installed Gambas with “sudo apt-get install gambas3”, and it installed Gambas 3.8 (ubuntu armhf).  When I launch it, I get “segmentation fault”.  So, I installed all of the dependencies, and checked out version 3.9 from the SVN repository.  It seemed to compile without too many issues (just some warnings that didn’t seem like much).  When I launch that version I get “illegal instruction”.
this confirm that the arch are not same, a possible could be that you are in multiarch mode and try to run a different arch, take in consideration that now in debian we can mix different archs


At this point I figured I would try compiling version 3.6 instead.  In this case, Make fails with “main.cpp:31:21: fatal error QDateTime: No such file or directory. Compilation terminated’.
this its a common qt4 vs qt5 dependency problem the qt installed are incomplete, you must revise packages and disable qt5 modules in gambas, install complete qt4 modules and then setupd with update-alternatives the qt environment correctly


I’m really more of a hardware guy, and I’m trying to build an embedded device based on this module.  I’m a long time vb6/vb.net<http://vb.net> person, and would really like to get Gambas working so as to avoid working in C.
its a common guindows problems, your cup are full of win32 knowlegde..
seems the problem in your case its a very older arm class hardware,

please can you report exact model in use for that?
