Hi,
Hello Bhupinder,
I am facing an issue where the recompilation fails when you build for ARM32 architecture on an existing build of ARM64. Even if I do make clean/make distclean before compiling for different architecture it still fails. Steps to reproduce the issue: 1. git clone git://xenbits.xen.org/xen.git <http://xenbits.xen.org/xen.git> xen.git 2. make dist-xen XEN_TARGET_ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu 3. make distclean 4. make dist-xen XEN_TARGET_ARCH=arm32 CROSS_COMPILE=arm-linux-gnueabihf- Compilation fails at step 4. If I manually remove the following files and recompile then compilation is successful: Remove xen/arch/arm/asm-offsets.s Remove xen/arch/arm/xen.lds The same issue happens if you build for ARM32 first and then try to build for ARM64. After removing the 2 files manually, the compilation is successful. I am using the following toolchains: gcc-linaro-4.9-2014.11-x86_64_aarch64-linux-gnu.tar.xz (for ARM64 build) x86_64-gcc-4.9.0-nolibc_arm-unknown-linux-gnueabi.tar.xz (for ARM32 build - https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/) I think probably the above-mentioned two files need to be removed automatically when make distclean is run.
This is expected. You have to use make distclean will only clean the files of the host architecture (e.g x86). For cross-compilation, you will have to do make distclean XEN_TARGET_ARCH=arm64
