【问题描述】：
我对 C::B 很陌生，只是在构建 wxWidgets 的同时安装了它。我很确定我用 MinGW 构建的 wxWidgets 很好，我能够使用 wxWidgets 中的“minimal.cpp”示例在 C::B 中成功创建一个 wxWidgets 项目。但是，现在我没有创建一个空项目，而是使用在向导中未选中“空项目”来创建程序。使用 wxWidgets 这将创建 2 个源文件和 2 个头文件（用于应用程序和主文件）。当我尝试构建+播放项目时，虽然没有进行任何更改，但我收到此错误：
-------------- Build: Debug in MULLSIMPLE (compiler: GNU GCC Compiler)---------------

说找不到文件？ wxWidgets-3.0.5 实际上在 c:\Program Files/wxWidgets-3.0.5 中，所以也许它找错了地方？或者我错过了设置它的步骤？
这绝对是我安装 C::B、安装 wxWidgets 和创建我的项目所做的一切
1. Installing CodeBlocks
a. Clicked codeblocks-20.03mingw-setup.exe from website, then download started automaticallty from fosshub
b. Ran executable to install and for type of install did "All plugins, all tools, just everything"
-all checkboxes were checked, including
1. Default Install
2. Contrib Plugins
3. C::B CBP2Make
4. C::B Share Config
5. C::B Launcher
6. MinGW Compiler Suite
2. Downloading wxWidgets
a. Clicked "Windows ZIP" from downloads page on website under "Latest Stable Release: 3.0.5"
b. Extracted download to c:\Program Files\wxWidgets-3.0.5
-first file asked for administrator permission, i said "dont ask again" and clicked "continue"
3. Added MinGW to path
a. went into c:\Program Files\CodeBlocks\MinGW\bin and copied that path to PATH environment variables
4. Building wxWidgets
a. opened a terminal with admin privileges and went to c:\Program Files\wxWidgets-3.0.5\build\msw.
b. entered commands as suggested at https://wiki.wxwidgets.org/Compiling_wxWidgets_with_MinGW, except changed
BUILD=release to BUILD=debug:
1. mingw32-make -f makefile.gcc SHARED=1 UNICODE=1 BUILD=debug clean
2. mingw32-make -f makefile.gcc SHARED=1 UNICODE=1 BUILD=debug
c. wxWidgets successfully built (3:38 pm to 4:22pm!)
5. Opened CodeBlocks
a. got message that "After auto-detection, at least one compiler's master path is still empty and therefore invalid.
Inspect the list below and change the compiler's master path later in the compiler options. Select you favourite
default compiler here:"
-There's one compiler listed as detected: GNU GCC Compiler
-With this compiler highlighted, i clicked "Set as default" and then ok.
b. got message CodeBlocks is not default app for C/C++ source files.
-Selected "Yes, associate with C/C++ files"
7. Testing Compiler
-I wasn't sure what to do about "setting compiler master path..." msg earlier, so I just created a new project with type
"Console application", compiled the basic "Hello world" application, ran it, ran fine, so I assume compiler is working?
6. Create new wxWidgets program:
a. Create new project: wxWidgets project
b. Wizard Steps:
PAGE 1:
-Set version: wxWidgets 3.0.x
PAGE 2:
-Named project "MULLSIMPLE" and created directory
PAGE 3:
-Skipped Author info.
PAGE 4:
-Preferred GUI Builder: None
-Application Type: Frame Based
PAGE 5:
-wxWidgets location: C:\Program Files\wxWidgets-3.0.5
-When I hit next, it opens the global variable editor. I don't know how to use this,
so i just hit ok without making any changes. IT asked if i want to save an invalid global var,
i said yes. Now the widgets location in the wizard is a path instead of a global variable,
I assume this is ok for now
PAGE 6:
-By default "Debug" configuration checked, "Release" configuration is unchecked
-make no changes
PAGE 7:
-Under wxWidgets library settings:
-CHECK Use wxWidgets DLL
-UNCHECK wxWidgets built as monolithic
-CHECK enable unicode
-Under Miscellaneous settings:
-UNCHECK create empty project
-CHECK create and use PCH
-Leave configuration input field blank
-UNCHECK Configure Advanced Options
-On next get dialog re PCH default settings, click YES to accept
PAGE 8:
-Didn't select any additional libs to add to project,
just hit finish
8. Try Build and run
-Get the build log error at start of post re: missing files
谢谢

看起来很像 Program Files 中的空间正在吸引您。出于长久以来因痛苦而根深蒂固的偏执，我从不在重要路径中使用空格，所以我不知道引用路径是否应该工作。
-
@user4581301 感谢您的回复。好的，所以如果我将 wxWidgets-3.0.5 目录复制到另一个没有空格的目录，然后在 wxWidgets C::B 向导中更改该目录的位置，那会起作用吗？或者我必须清理然后重建我的整个 wxWidgets 安装
-
我会检查编译器的文档以及用于运行构建的任何 shell，看看他们首先说了什么，但看起来空间确实是问题所在。就我个人而言，我希望这些报价能够奏效。毕竟 2020 年太可怕了。
