Based on the aarch64 context specified in the original note (system version, /usr/ports versions, and the like). . . The following built fine: =3D=3D=3D>>> The following actions were performed: Re-installation of aarch64-none-elf-gcc-6.3.0 Installation of devel/arm-none-eabi-binutils = (arm-none-eabi-binutils-2.27_5,1) Installation of devel/arm-none-eabi-gcc = (arm-none-eabi-gcc-6.3.0) But devel/arm-none-eabi-gcc492 then conflicts with devel/arm-none-eabi-gcc : =3D=3D=3D> Registering installation for arm-none-eabi-gcc492-4.9.2_2 Installing arm-none-eabi-gcc492-4.9.2_2... pkg-static: arm-none-eabi-gcc492-4.9.2_2 conflicts with = arm-none-eabi-gcc-6.3.0 (installs files into the same place). = Problematic file: /usr/local/bin/arm-none-eabi-c++ *** Error code 70 So to test devel/arm-none-eabi-gcc492 fully requires that any pre-installed devel/arm-none-eabi-gcc first be deleted/removed. There is every indication that absent the conflict devel/arm-none-eabi-gcc492 would have installed just fine and it did build to the point of installing. So the following did not have package problems: devel/aarch64-none-elf-gcc-6.3.0 devel/arm-none-eabi-gcc But that last was given that devel/arm-none-eabi-gcc492 had not been installed. I still have the following to go on aarch64 (cortex-a53): devel/powerpc64-gcc devel/riscv64-gcc devel/sparc64-gcc devel/amd64-gcc I also have armv7 (cortex-a7) attempting: devel/arm-none-eabi-gcc492 devel/amd64-gcc =3D=3D=3D Mark Millard markmi at dsl-only.net
