Hey,
I got the same issue as you did trying to compile a simple C++ (11) program
for the frdm-k64f platform on Ubuntu 14.04
The culprit was the arm-none-eabi-gcc package you can download for this
version of Ubuntu is broken.
What worked for me is to fetch it from following ppa:
https://launchpad.net/~terry.guo/+archive/ubuntu/gcc-arm-embedded
However, unlike what's written there, you shall then "install sudo apt-get
install gcc-arm-none-eabi=4.9.3.2015q3-1trusty1"
Mind the difference at the end, when selecting the package...Not trusty13,
but trusty1
You end up getting a working compiler and sysroot, eliminating the error
you mentioned.
Have a great day
Patrick
Hi all,
I am currently trying to run the cpp tests (e.g. tests/cpp11_*) for
stm32f4discovery on ubuntu 14.04 unfortunately all tests I ran failed (see
error log at the bottom of this mail). I highly suspect that this is a
toolchain issue (btw: happens only with stm32f4discovery).
Did I miss something obvious like a missing package (see package list
below)?
Best,
Philipp
