I am trying to cross-compile for raspberry B/raspberry zero on ubuntu18.04 using crossbuild-essential-armhf. I installed it using :

apt-get install -y crossbuild-essential-armhf

In order to test I am using a simple hello world file hello.c:

#include <stdio.h> 
int main() {
        return 0; 

Using :

arm-linux-gnueabihf-gcc hello.c

The executable crash with segmentation violation, the stack is then :

#0  0x0044f5c2 in ?? ()
#1  0x0040040e in _start ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)

So I tried to build using different commands searching on internet like :

arm-linux-gnueabihf-gcc -marm -march=armv6 hello.c
arm-linux-gnueabihf-gcc -marm -mcpu=arm1176jzf-s hello.c
arm-linux-gnueabihf-gcc -marm -march=armv6 -mfpu=vfp -mfloat-abi=hard hello.c

But the stack is always the same.

Using the "historical" https://github.com/raspberrypi/tools.git is working but this gcc-4.8 compiler is far too old to compile modern code.

Is there a way to produce raspberry B/raspberry zero binaries using a gcc-7 cross compiler ?

  • As far as I'm aware, stock distro cross-compilers are arm7, so you can compile for the multi-core models but not the single core ones. The one from the rpi tools repo, on the other hand, should be good for all of them. – goldilocks May 2 '19 at 18:24
  • @goldilocks: I tried to compile using -marm -march=armv6 but it crash the same. The assembly is different using it. – mpromonet May 2 '19 at 18:27
  • The _start address is different with rpi-tools 000082f0 <_start>, and with crossbuild-essential-armhf 000003fc <_start> – mpromonet May 2 '19 at 18:42
  • You might have a look at gcc -v for both. I think you are right that if it accepted the switch, it must be armv6 capable, but can't hurt to check (-v will list a Target). – goldilocks May 2 '19 at 19:02

Here's what I do for C++

sudo apt-get install build-essential
sudo apt-get install g++-arm-linux-gnueabihf
sudo apt-get install gdb-multiarch

then arm-linux-gnueabihf-g++ -v to test the installation.

After that, open "testing.cpp" and put in

#include <iostream>
using namespace std;

int main() 
    cout << "Hello, World!";
    return 0;


arm-linux-gnueabihf-g++ -O3 -g3 -Wall -c -o -fPIC "hello.o" "hello.cpp"
arm-linux-gnueabihf-g++ -o "hello" hello.o

Check the binary to make sure it's been compiled correctly: file hello should yield hello: ELF 32-bit LSB executable,ARM, EABI5 version 1 (SYSV)... The ARM is what you're looking for. If it's present, you're good to go.

    For C++ I have the same segv, this is why I try to simplify using C. Independently of the option using file I get ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV). I run sudo apt-get install build-essential g++-arm-linux-gnueabihf gdb-multiarch, compile with arm-linux-gnueabihf-g++ -O3 -g3 -Wall -fPIC hello.cpp and it crash the same with your hello.cpp. Are you using ubuntu bionic ? – mpromonet May 2 '19 at 18:19
  • @mpromonet No, I'm not using Ubuntu, I'm on Debian. – user96931 May 2 '19 at 18:35
  • The raspberry I am using is a raspberry pi B+ (BCM2835 revision 0010) – mpromonet May 2 '19 at 18:45
  • you lost me, I am trying to crosscompile to armv6 which is a arm 32 bits, I don't try to compile for x86-64..... – mpromonet May 3 '19 at 19:30

I ran into a similar issue trying to cross-compile code for the Raspberry PI Zero (armv6) using a newer GCC 8.

Current toolchains are often not built with the --with-arch=armv6 flag. This results in binaries which are not compatible with armv6 and therefore you may get Illegal Instruction error.

I created a github repo where you can download a toolchain based on a current GCC version for the Raspi Zero (and also for all the other RasPI)



Using the compiler toolchain from https://sourceforge.net/projects/raspberry-pi-cross-compilers/

For pizero the cross-compiler is available from the link cross-gcc-9.1.0-pi_0-1.tar.gz

This compiler version is :

Using built-in specs.
Target: arm-linux-gnueabihf
Configured with: ../configure --prefix= --target=arm-linux-gnueabihf --enable-languages=c,c++,fortran --with-sysroot=/arm-linux-gnueabihf/libc --with-build-sysroot=/opt/cross-pi-gcc-9.1.0-0/arm-linux-gnueabihf/libc --with-arch=armv6 --with-fpu=vfp --with-float=hard --disable-multilib
Thread model: posix
gcc version 9.1.0 (GCC)

Building with :

arm-linux-gnueabihf-gcc hello.c

build an executable that run on raspberry zero.
