Question

我已经在Eclipse中构建了一个已经运行的c ++ + wxWidgets应用程序，并使用MSYS构建了wxWidgets。

现在我想尝试不同的IDE，比如CodeLite和Code :: Blocks，但是当我尝试它们时它们没有用，因为我缺少他们想要的build.cfg文件。所以我尝试了一种“干净”的方式，备份了wxWidgets并使用MinGW32-make而不是MSYS再次构建它们。

尝试代码：阻止现在，我得到了很多“未定义的引用”错误，我无法理解我做了什么或设置错误。

我会尝试在此提供所有相关信息：

wxWidgets的路径：

C:\SVILUPPO\TOOLS\wxWidgets

路径变量（相关部分）

PATH=C:\SVILUPPO\TOOLS\MinGW\bin;C:\SVILUPPO\TOOLS\MinGW\libexec\gcc\mingw32\4.8.1;

Mingw v4.8.1，make version

C:\SVILUPPO\TOOLS\wxWidgets>mingw32-make -v
GNU Make 3.82.90
Built for i686-pc-mingw32

wxWidgets构建命令：

C:\SVILUPPO\TOOLS\wxWidgets\build\msw>mingw32-make -f makefile.gcc BUILD=debug UNICODE=1 SHARED=0 MONOLITHIC=1

我还尝试在链接器设置中添加我在arm-linux下构建此代码时必须添加的其他库，但这些库文件不存在（我猜是因为MONOLITHIC选项）：

libwxmsw30ud_core.a
libwxmsw30ud_html.a
libwxmsw30ud_adv.a
libwxbase30ud_xml.a
libwxmsw30ud_richtext.a

最后，我不知道最后应该从Code :: Block链接和调试我的源代码。

Answer 1

您需要链接在构建wxWidgets时创建的libwxexpat.a。

无法使用Code :: Blocks / MinGW
