在使用wxgtk链接程序时，我得到了未定义的引用。我试过来自其他地方的建议，比如定义unicode宏和--no-as-needed，但都没有解决问题。这些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库应该是两个使用的。
答案 0 :(得分：0)
wxString位于库wxBase中。
您正在链接
-lwx_baseu-2.8-arm-angstrom-linux-gnueabi
我假设是wxBase库。
您可以链接示例程序吗？ （答案：是）因此，请发布您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。
看一下你的'sample'链接命令行，我注意到样本是使用非unicode版本的库编译的，而失败的链接是使用unicode版本。我建议尝试使用unicode构建样本，并且没有测试程序 - 结果应该是提供信息的。
-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
该示例使用 -lwx_base_xml-2.8-arm-angstrom-linux-gnueabi ，但您使用 -lwx_baseu-2.8-arm-angstrom-linux-gnueabi 您是否尝试过改变了吗？
