Question

我安装了wxWidgets，然后按照说明使用MSYS。完成后，我从一个站点复制了一个样本并将其放在eclipse中的一个项目中。代码是：

#include <wx/string.h>

int main(int argc, char **argv)
{
  wxPuts(wxT("A wxWidgets console application"));
}

但是当我编译时，我得到了这个错误：

**** Build of configuration Debug for project test2 ****

**** Internal Builder is used for build               ****

g++ -O0 -g3 -Wall -c -fmessage-length=0 -osrc\test2.o ..\src\test2.cpp
..\src\test2.cpp:9:23: wx/string.h: No such file or directory
..\src\test2.cpp: In function `int main(int, char**)':

..\src\test2.cpp:13: warning: unused variable 'wxT'
..\src\test2.cpp:13: warning: unused variable 'wxPuts'
Build error occurred, build is stopped

我做错了什么？

我编辑了设置，但我还是得到了这个。没有 - 我还是..

Answer 1

好像你没有设置正确的include目录来查找wx头文件（编译器命令行上没有-I ...）。

你可以在C ++下的CDT项目的项目设置中添加包含目录 - > gt> Settings-＆gt; GNU C ++ - ＆gt; Include目录（或类似我目前没有Eclipse运行所以名称方式不同）。

修改

您已更改“GCC Assembler”包含路径。由于您没有编译汇编程序，因此不使用此部分。您需要在“GCC C ++编译器”路径中编辑包含路径！

也许指南here可能会对您有所帮助，因为您已经构建了这个库，我想您只读了标题为验证wxWidgets库正在工作以后的部分。

将WxWidgets与Eclipse一起用于C ++
