Wxwidgets wxstring未定义引用

在使用wxgtk链接程序时，我得到了未定义的引用。我尝试了其他地方的建议，比如定义unicode宏和——不需要，但都没有解决这个问题。以下是链接器错误的示例：

undefined reference to `wxStringBase::InitWith(wchar_t const*, unsigned int, unsigned int)'
undefined reference to `wxString::mb_str(wxMBConv const&) const'
undefined reference to `operator+(wchar_t const*, wxString const&)'

这是用于链接以下内容的行：

重新排列链接参数并没有改变结果，似乎链接器中使用的两个wx lib应该是已使用的两个。

wxString位于库wxBase中

您正在链接到

-lwx_baseu-2.8-arm-angstrom-linux-gnueabi 

我假设它是wxBase库

你能把示例程序链接起来吗？（回答：是的）因此，请发布用于构建其中一个示例的链接命令，以便与失败的链接命令进行比较

看看“sample”链接命令行，我注意到示例是使用非unicode版本的库编译的，而失败的链接使用的是unicode版本。我建议尝试使用unicode构建示例，而不使用unicode的测试程序-结果应该是有用的

-lwx_base_xml-2.8-arm-angstrom-linux-gnueabi
-lexpat -lwx_gtk2_adv-2.8-arm-angstrom-linux-gnueabi
-lwx_gtk2_html-2.8-arm-angstrom-linux-gnueabi
-lwx_gtk2_core-2.8-arm-angstrom-linux-gnueabi 
-lwx_base-2.8-arm-angstrom-linux-gnueabi

示例使用了-lwx\u base\u xml-2.8-arm-angstrom-linux-gnueabi，但是您使用了-lwx\u baseu-2.8-arm-angstrom-linux-gnueabi您尝试过改变吗？

链接示例程序似乎很好。下面是小部件示例运行时的链接行。将链接更改为使用unicode也可以完成。有趣的是，在编译wxgtk时，我指定使用unicode。不确定非unicode来自何处。base_xml与base是不同的库。以下是我编译的LIB列表：
