Re: [beagleboard] Running Qt gui application on BBB

[Bremenpl]

I think there is a good reason to get one then. If it only had on board memory it would be nearly as cool as beagle.

W dniu 2015-12-15 o 01:21, William Hermans pisze: So just thinking for a minute. A Raspberry PI 2, the new board with quad cores, and 1 GB ram would probably work fairly decent as a build system for the Beaglebones. Granted, something like the X15, of that new nVidia ARM board, or even the Omelex A20 board with SATA would probably be a much better choice if cost is not a problem. By the way, I have no idea what Robert is talking about. You need to ask him.

I thought there would be qt installed and all. Am I missing something again? W dniu 2015-12-15 o 00:54, William Hermans pisze: Not necessarily, but consider this. How much does an embedded systems specialist in your area get paid per hour ? In my area, about 15-20 years ago. The cost of a board like the X15 would have been absorbed in roughly half a day. That is to say, an embedded systems specialist could buy a board for $239 after working roughly half a day. Now take into account that figuring out how to cross compile something like this is a serious headache, and often takes days, if not weeks to get right . . .

W dniu 2015-12-15 o 00:26, William Hermans pisze: I cant change the board right now, it has to be BeagleBone Black. Thats why I need to build on my host. Did you succed on installing QT5.1 and deploying it to BeagleBone Black? Maybe I should use it instead of 4.8.6 if its easier? No one was saying change boards. Use the same board, but use a faster, more powerful ARM board to compile native ARM executable. The reasons are simple. No need to mess with cross compiling, which in many cases is messy, and sometimes near impossible. You don't think Robert spends days, or weeks compiling packages do you ? But why don't we ask Robert. Robert, hey what percentage of the packages you build are compiled native to ARM, from some sort of beefy ARM board? I'm guessing nearly 100% if not 100% but . . .

Hope to get it working in a while if i wont fall asleep on my desk!

AT first I will try to open the app on the BeagleBone Black itself. But after that works I need to figure out how to remote debug while building on beagle instead of cross compile on host. Could you please only clarify my thoughts about it? If gdb-multiarch needs crosscompiled executable, how do I use it if I dont download the executable from target like you said i dont? On BBB you run gdbserver. On your host, you run gdb and then remote connect to your gdbserver. Watch Derrek Molloy’s chapter 7 video I gave you, starting at about 30 minutes.

So lets say I would have a postbuild script on my host, that after each succesfull build would scp over all .h and .c files to BeagleBone Black and build on the target as well (ssh command). But then again, for gdb-multiarch I need to provide an executable on the host. So if I am building on target device, do I need to download the built executable back to host…?

The point is, can I remote debug in this configuration? gdb can communicate over tcp/ip..
