Artik710でMonoを動作させるのに問題があります。私はfedora 24のパッケージ "mono-devel"をインストールしました。そしてDNFはすべてが問題ないと言います。 しかし、最小の "Hello world"プログラムをmcsでコンパイルしようとすると、セグメンテーション違反が発生します。
また、PC上でプログラムをコンパイルし、Artik710で "mono hello.exe"を実行しようとすると、セグメンテーションフォルトも発生します。
ちょうど "モノ-V" が動作し、言う：Mono on Artik710

私はこの問題は、64ビットのCortex A-53コアプロセッサ上で32ビットOS（したがって32ビットモノラル）を実行することによって引き起こされると仮定する。ですから、問題は - 32ビットOS上にx64 Monoをインストールする（またはソースコードからビルドする）方法はありますか？それはうまくいくでしょうか？他に何か問題がありますか？ここでのHello worldプログラム（非常に有用ではない）を実行しているGDBからいくつかのスタックトレースは次のとおりです。任意のヘルプ

ありがとう！
注：actualy私の "Hello World" のプログラムをデバッグvalgrindのツールの下
はモノラルで動作します。だから、 "mono /root/Release/HelloWorldArtik.exe"を実行すると、 "Segmentation failed（core dumped）"だけが返されます。私が実行した場合、 "valgrindの--tool = memcheck -v --leak-チェック=フル--smcチェック=すべてが/root/Release/HelloWorldArtik.exeモノ" しかし、リターンは次のとおりです。
