代码块/mingw & Windres 使用 png 资源构建 .dll（VST 插件）时出现问题

我有一个 VST 插件，可以与 VS200X / MSVC 很好地编译。我正在尝试为喜欢该环境的用户制作一个 Codeblocks/MinGW 项目。

当我使用代码块构建 dll 时，它可以在 VST 主机中使用 GUI 运行，直到我开始尝试包含资源（.png 文件）为止，

我将 .rc 文件包含在代码块项目中。我的resource.h 中的资源路径没有空格。

如果我尝试复制构建的 .dll 文件，操作系统会将其锁定。几乎就好像 Windres 没有成功编译资源并保留了文件的句柄 - 尽管从 .dll 的大小来看，资源似乎在那里。如果我尝试通过 GDB 在 vst 主机中运行 dll，它不会遇到任何断点...大概主机无法加载 .dll。

这是代码块 cbp 编译器设置...

原文

I have a VST plugin that compiles fine with VS200X / MSVC. I am trying to make a Codeblocks/MinGW project also for users who prefer that environment.

When I build the dll with codeblocks it works in a VST host, with GUI, until I start trying to include resources (.png files)

I include the .rc file in the codeblocks project. The resource paths in my resource.h don't have spaces.

If i try and copy the built .dll file the OS has it locked. It is almost as if windres is not compiling the resources successfully and retains a handle on the file - although by the size of the .dll it looks like the resources are there. If I try and run the dll in a vst host via GDB it doesn't hit any breakpoints... presumably the host can't load the .dll.

here are the codeblocks cbp compiler settings...
