You can get a quote from VICON (https://vicon.com/) for your particular needs. We do support other mocap systems such as OptiTrack or Qualisys. Bitcraze LPS has not been tested with the Crazyswarm, yet.

That is one effective way to bypass the system binary path :-).

Are you running make in eclipse or another ide or in a terminal?

Re: the problem in compiling the crazyflie-firmware in terminal in ubuntu16.04

Just to make sure: are you running make in the same console in which you checked the version of the compiler, or are you using an IDE, Also, in the compiler package there is a 'bin' folder and a 'arm-none-eabi/bin' folder. You need to have the 'bin' folder in your path, not the other one. The 'arm-...

Re: the problem in compiling the crazyflie-firmware in terminal in ubuntu16.04

Have you tried to locate your gcc with "which" and add the path as I proposed? The Crazyflie Makefile will use arm-none-eabi-gcc by default. You can configure which compiler is used by setting the "CROSS_COMPILE" environment variable. Though, if you set the PATH variable as I explained in my last p...

Re: the problem in compiling the crazyflie-firmware in terminal in ubuntu16.04

to find which version of GCC is used by the Makefile you can type "which arm-none-eabi-gcc". To get your version to run you can add its folder to your path first. One solution is to add at the end of the file ~/.bashrc: export PATH=/usr/bin/gcc-arm-none-eabi-7-2017-q4-major/bin/:$PATH Then start a ...

Re: the problem in compiling the crazyflie-firmware in terminal in ubuntu16.04

This warning sometime appears with old version of arm-none-eabi-gcc. It will not happen with the gnu arm toolchain: https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads (this is the one we use in our build servers). Hi,Arnaud accroding your link,i download the latest arm-none-eabi-g...
