Hi,
This is the second version of the patch to enable cross building OSv
in multiarch distros. This version updates the second patch to rely on
the newly added boost_base support.
Cover letter from previous version -
Here's a couple of fixes to rely on the compiler to resolve library
locations during the build rather than using hard coded paths in the
build/Makefile when cross compiling. With these, I am able to cross
build OSv for arm64 on Debian using -
$ export CROSS_PREFIX="aarch64-linux-gnu-"
$ ./scripts/build -j8 arch=aarch64 fs=rofs image=native-example
The following steps can be used to setup the environment -
# dpkg --add-architecture arm64
# apt install gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
libboost-system-dev:arm64
As an additional benefit of the patches, it is now also possible to
use CROSS_PREFIX to speed up compilation for both native and cross
scenarios using ccache without messing with symlinks to compiler
binaries -
$ export CROSS_PREFIX="ccache " # native
or
$ export CROSS_PREFIX="ccache aarch64-linux-gnu-
I've tested this on Debian both native and cross. Any additional
testing especially on Fedora / CentOS which do not provide multiarch
would be appreciated.
Thanks,
Punit
