Cross building for arm64 on x64 host issues #94
Comments
|
How about the below? $ source /opt/poky/3.1.15/environment-setup-aarch64-poky-linux
$ export CC=${CLANGCC}
$ export CXX=${CLANGCXX}
$ flutter-elinux build elinux --target-arch=arm64 --target-compiler-triple=aarch64-poky-linux |
Yes I did those. |

Hi Matsubayashi, Commands Run: Failed to cmake build: In file included from If I use the "--system-include-directories" option (https://github.com/sony/flutter-elinux/wiki/Building-flutter-apps#troubleshooting), it gives a different error.

Could you use $ sudo mv /opt/poky/3.1.16/sysroots/x86_64-pokysdk-linux/usr/bin/ld /opt/poky/3.1.16/sysroots/x86_64-pokysdk-linux/usr/bin/ld.x86_64
$ sudo cp -a /opt/poky/3.1.16/sysroots/x86_64-pokysdk-linux/usr/bin/aarch64-poky-linux/aarch64-poky-linux-ld /opt/poky/3.1.16/sysroots/x86_64-pokysdk-linux/usr/bin/ld$ source /opt/poky/3.1.15/environment-setup-aarch64-poky-linux
$ export CC=${CLANGCC}
$ export CXX=${CLANGCXX}
$ flutter-elinux build elinux --target-arch=arm64 --target-compiler-triple=aarch64-poky-linux --target-sysroot=/opt/poky/3.1.16/sysroots/aarch64-poky-linux |

Also, I updated Case 2: Use Yocto SDK. |

I'll close this issue, but please let me know if you have still any problems. |

Hi Matsubayashi, This command "flutter-elinux build elinux --target-arch=arm64 --target-compiler-triple=aarch64-poky-linux --target-sysroot=/opt/poky/3.1.16/sysroots/aarch64-poky-linux" works. It is strange that I tried that command before and it didn't work with the exact same steps. Probably now it works because my Poky version is now 3.1.16? Anyways, Thanks for your help :) |

It sounds nice. You're welcome. |
Hi @HidenoriMatsubayashi ,
I followed the guide in https://github.com/sony/meta-flutter to cross build using Yocto sdk (Skipped Cross-building using bitbake section). Everything succeeded. Then, I ran "source /opt/poky/3.1.15/environment-setup-aarch64-poky-linux" , "export CC=${CLANGCC}" and "export CXX=${CLANGCXX}". After that, I tried to run "flutter-elinux build elinux --target-arch=arm64
--target-compiler-triple=aarch64-poky-linux --system-include-directories=/usr/aarch64-linux-gnu/include/c++/9/aarch64-linux-gnu -v" in https://github.com/sony/flutter-elinux/wiki/Building-flutter-apps#case-2-use-yocto-sdk.
But it gave me the following errors:

Followed the instructions in sony/flutter-embedded-linux#4 (comment) to disable the compiler test for C and C++, set the target architecture and swap the x86_64 and the ARM64 linker as the Yocto SDK is using the wrong linker.
