不能 link wxWidgets 应用程序与 Code::Blocks / MinGW

Question

我有一个在 Eclipse 中构建的已经运行的 c++ + wxWidgets 应用程序，其中 wxWidgets 使用 MSYS 构建。

现在我想尝试不同的 IDE，例如 CodeLite 和 Code::Blocks，但是当我尝试它们时它们不起作用，因为我缺少它们想要的 build.cfg 文件。所以我尝试了 "clean" 方法，备份了 wxWidgets 并使用 MinGW32-make 而不是 MSYS 再次构建它们。

现在尝试 Code:Block，我遇到了很多 "undefined reference" 错误，而且我不明白我做了什么或设置错了什么。

我会尽量在这里提供所有相关信息：

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\mingw32.8.1;

Mingw v4.8.1, make 版本

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

Code::Block 构建日志：

我还尝试在 linker 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 '导致 MONOLITHIC 选项）：

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

最后，我不知道我最终应该如何 link 并从 Code::Block 调试我的源代码。

Answer 1

您需要 link 和 libwxexpat.a ，它是在您构建 wxWidgets 时创建的。

不能 link wxWidgets 应用程序与 Code::Blocks / MinGW

Can't link wxWidgets app with Code::Blocks / MinGW

c++

linker

wxwidgets

mingw

codeblocks
