wxWidgets交叉编译 - 错误：数组'_GStaticAssertCompileTimeAssertion_0'的大小为负数

Question

我试图在64位Linux机器上为32位Linux编译静态wxWidgets 3.1库。

我的配置如下：

../configure "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32" --host=i686-pc-linux-gnu --build=x86_64-pc-linux-gnu --disable-shared --enable-unicode
make

该库开始构建，但在中途我收到此错误：

我注意到错误提到了glib和gtk-2.0。 我错过了这些软件包的变体还是我的配置错了？ 我相信我的配置应该是正确的。 我的configure是否有特殊的wxWidgets特定选项？

在寻找答案之后，似乎在64位Linux上对32位Linux进行交叉编译的最佳方法是使用chroot构建环境。 这显然是许多开发人员所做的。

Github上有一些很好的说明。
