如何解决在MacOS上为ARM交叉编译druid
我正在尝试使用MacBook Pro为树莓派3B模型交叉编译linebender/druid hello-world。我正在使用rustembedded-cross项目及其 armv7-unknown-linux-gnueabihf 链也可以做到这一点。然后我意识到这是行不通的，可能是因为所使用的工具链没有 gtk-3 （Druid的先决条件）。没问题，您可以扩展image并提供交叉配置以告诉它使用它。从那里我安装了gtk3.0和libgtk-3-dev。
这失败了，因为gtk的版本略低于要求，因此我重建了工具链image，并将其ubuntu的基本映像提高到了18。
已编译！但是，它没有链接。链接器失败，并显示以下错误。
如果我跑步
pkg-config --libs gtk+-3.0
我收到
-lgtk-3 -lgdk-3 -lpangocairo-1.0 -lpango-1.0 -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0
我的问题是：为什么会发生这种情况，我该如何解决？
