Re: [edk2-devel] Problems building some Arm platforms (__stack_chk_guard/__stack_chk_fail, _GLOBAL_OFFSET_TABLE_)

Fri, 19 Aug 2022 18:52:04 -0700

I'm using gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1) on Ubuntu 20.04.4, from the Ubuntu repo. 

I'm building it with:


export PACKAGES_PATH=$PWD/edk2:$PWD/edk2-platforms:$PWD/edk2-non-osi
export WORKSPACE=$PWD
export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-

. ./edk2/edksetup.sh
build -p ./Features/Ext4Pkg/Ext4Pkg.dsc -a AARCH64 -b RELEASE -t GCC5


Some of the messages are:

Hi Rebecca,
What EDK2 toolchain are you using? And how is your toolchain configured (or where did you get it from?)? It seems that it's trying to use the stack protector automatically... 

Thanks,
Pedro

    ./Features/Ext4Pkg/Ext4Pkg.dsc is also failing - with errors about

    And I get an error from Andy Hayes' email: "Your message couldn't
    be delivered to the recipient because you don't have permission to

    I have an armplatbld.sh script that goes through and tries to

    I'm think this used to work for these, but I'm getting some
    errors now.

    I'm using edk2-platforms 46686eeb7e78efe603badd86f13777d9fb070fb8
