CoreCLR 在龙芯上的的二进制包（CoreCLR binary package on Loongson）

[whuanle]

你好，前些天我为了尝试龙芯和 CoreCLR，我写了一篇文章，
https://www.cnblogs.com/whuanle/p/13196860.html
基础库已经基本安装完毕，但是编译速度太慢，所以放弃了最后一步。
龙芯团队已经编译并测试了 CoreCLR，是否可以直接提供编译后的二进制包呢~

编译环境比较复杂，而且编译需要大量时间，二进制包是最理智的方法了~

可以在X86上交叉编译：

ROOTFS_DIR=/home/zhaixiang/chroots/mips64el_loongnix ./build.sh mips64 release cross ignorewarnings

Screenshot from my Fedora 30:

灵珑 9S2A
Linux Loongson 2.6.27.1 #6 Wed Nov 10 16:17:35 CST 2010 mips64 GNU/Linux
Debian GNU/Linux 5.0

Debian上做chroot上很容易： https://wiki.debian.org/chroot

十分感谢您的关注和试用！我们近期会发布构建好的二进制，到时信息会发布在https://github.com/gsvm/loongson-dotnet 和 http://www.loongnix.org 。初期构建出的.NET Core的二进制还基本处于不可用状态，仅供CoreCLR的开发者测试用，需要一段时间的迭代才能达到供.NET Core的用户实用的程度。

交叉编译是个好办法，也可尝试包含了rootfs的现成的镜像：
loongnix:

docker run --rm -v `pwd`:/coreclr -w /coreclr -e ROOTFS_DIR=/crossrootfs/mips64el_loongnix aoqi/dotnet-buildtools:x86_64-ubuntu-16.04-c103199-20180628134544-upstream-cross-mips64el ./build.sh release ignorewarnings mips64 cross skipcrossgen cmakeargs -DOBJCOPY=/crossrootfs/mips64el_loongnix/usr/bin/mips64el-linux-gnuabi64-objcopy

debian:

docker run --rm -v `pwd`:/coreclr -w /coreclr -e ROOTFS_DIR=/crossrootfs/mips64el aoqi/dotnet-buildtools:x86_64-ubuntu-16.04-c103199-20180628134544-upstream-cross-mips64el ./build.sh release ignorewarnings mips64 cross skipcrossgen

Feel free to test with QEMU machine :-)
We're on the way to get TCG/Loongson support and loongson3-virt machine support upstreamed.

@FlyGoat I'm still trying to get a machine for this project. I've read your tutorial about QEMU here: https://wiki.godson.ac.cn/virtual_machine_software:qemu:emulate_loongson

Would the QEMU performance be good enough, or at least acceptable to carry on coreclr work?

Should be enough for testing & debugging purpose. I'm using it with Jenkins to run IonMonkey tests.
But don't expect too much~ You'd better get a machine if possible.
