Building problem PX4 using Ubuntu 64

[Jose Luis]

Hi

I've followed the interaction to install ardupilot in my computer (Ubuntu 64). However, when I build the code (make px4-v2) the following error is returned :

/ardupilot/libraries/AP_RSSI/AP_RSSI.cpp:18:20: fatal error: utility: No such file or directory
#include <utility>

Can anybody help me?

Regards

José Luis

Did you install the correct toolchain version? Try make VERBOSE=1
px4-v2 and check it's using the correct compiler (check compiler
version by passing -v to whatever compiler it's using)

This is probably that missing `git submodule intit` and `git submodule update` issue. I tested this today in a VM and these instructions worked: http://dev.ardupilot.com/wiki/building-px4-for-linux-with-make/

I don't think it's the same issue since in his case it was failing to
build because the toolchain didn't have the <utility> header.

Anyway, if it works for you it's probably something missing in his
setup and not something wrong with the instructions.

Hi,

Got the same problem : 

CXX:     /home/khancyr/Workspace/ardupilot/libraries/AP_RSSI/AP_RSSI.cpp

/home/khancyr/Workspace/ardupilot/libraries/AP_RSSI/AP_RSSI.cpp:18:20: fatal error: utility: No such file or directory

 #include <utility> 

                    ^

compilation terminated.

I use Wily default arm-none-eabi toolchain : http://packages.ubuntu.com/fr/wily/devel/gcc-arm-none-eabi and Lubuntu 15.10

Could you try using the supported toolchain instead?

Hummmm 

here is the error ...

So default Ubuntu 15.10 Toolchain doesn't work ...  http://packages.ubuntu.com/fr/wily/devel/gcc-arm-none-eabi

Trying the one from diydrone website is working .

The one from Terry Guo ppa is also working : https://launchpad.net/~terry.guo/+archive/ubuntu/gcc-arm-embedded ( using sudo apt-get install gcc-arm-none-eabi=4.9.3.2015q3-1wily1) (It is faster than download from dyidrone website)

I just see that gcc-arm-embedded changed their ppa (https://launchpad.net/gcc-arm-embedded/+announcement/13824)

And interresting fact : it build and works though it is not recommended 

gcc-5
