vs2019 wxwidgets 示例 hello world -> "wxstrcoll not found"

Question

好像很多人都遇到了这个问题，我似乎找不到解决方案。

按照确切的说明进行操作，下载预编译库，v 3.0.5 - 最新的稳定版本

set wxwin env var
make new 32bit empty project
copy the hello world app into new source file
set additional include
set preproc defintions -> UNICODE & _UNICODE on
set linker libs

构建 ->

Answer 1

不幸的是，您需要手动修改 header 以修复 3.0.5 中使用 MSVS 2019 的构建，并删除 wxNEEDS_DECL_BEFORE_TEMPLATE 中 wx/wxcrt.h 定义之前的 defined(__VISUALC__) || 部分检查=].

FWIW 此问题已在 wx 3.1 中修复了很长时间（~6 年），您可以使用 MSVS 2019 开箱即用地编译 3.1.3 或即将发布的 3.1.4。
