这个错误的解决方法很简单，哪个cpp文件产生了这些错误，就在该文件中加入下面一行头文件：
#include <windows.h>
加入了上面这行声明后，可能会引发另外一个错误：
1>selectionTransformTool.cpp(209): error C2589: ‘(‘ : illegal token on right side of ‘::‘ 1>selectionTransformTool.cpp(209): error C2059: syntax error : ‘::‘ 1>selectionTransformTool.cpp(210): error C2589: ‘(‘ : illegal token on right side of ‘::‘ 1>selectionTransformTool.cpp(210): error C2059: syntax error : ‘::‘
发生这个错误的地方一般会调用max或者min函数，原因是windows.h里面将max和min定义成了宏，我们只需在#include <windows.h>这行前面加上下面这行即可：
#define NOMINMAX
如果Qt中使用了OpenGL模块，可能会出现下面这行错误：
1>cloudEditorWidget.obj : error LNK2019: unresolved external symbol _gluPerspective@32 referenced in function "protected: virtual void __thiscall CloudEditorWidget::resizeGL(int,int)" (?resizeGL@CloudEditorWidget@@MAEXHH@Z)
解决方法是在项目Properties -> Linker -> Input 中加入：
GLu32.lib
还有如果用了Qt的UI，可能会有如下的错误：
1>cloudEditorWidget.obj : error LNK2019: unresolved external symbol "public: static struct QMetaObject const CloudEditorWidget::staticMetaObject" (?staticMetaObject@CloudEditorWidget@@2UQMetaObject@@B) referenced in function "public: static class QString __cdecl CloudEditorWidget::tr(char const *,char const *)" (?tr@CloudEditorWidget@@SA?AVQString@@PBD0@Z) 1>cloudEditorWidget.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall CloudEditorWidget::metaObject(void)const " (?metaObject@CloudEditorWidget@@UBEPBUQMetaObject@@XZ) 1>cloudEditorWidget.obj : error LNK2001: unresolved external symbol "public: virtual void * __thiscall CloudEditorWidget::qt_metacast(char const *)" (?qt_metacast@CloudEditorWidget@@UAEPAXPBD@Z) 1>cloudEditorWidget.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall CloudEditorWidget::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@CloudEditorWidget@@UAEHW4Call@QMetaObject@@HPAPAX@Z) 1>denoiseParameterForm.obj : error LNK2019: unresolved external symbol "public: static struct QMetaObject const DenoiseParameterForm::staticMetaObject" (?staticMetaObject@DenoiseParameterForm@@2UQMetaObject@@B) referenced in function "public: static class QString __cdecl DenoiseParameterForm::tr(char const *,char const *)" (?tr@DenoiseParameterForm@@SA?AVQString@@PBD0@Z) 1>denoiseParameterForm.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall DenoiseParameterForm::metaObject(void)const " (?metaObject@DenoiseParameterForm@@UBEPBUQMetaObject@@XZ) 1>denoiseParameterForm.obj : error LNK2001: unresolved external symbol "public: virtual void * __thiscall DenoiseParameterForm::qt_metacast(char const *)" (?qt_metacast@DenoiseParameterForm@@UAEPAXPBD@Z) 1>denoiseParameterForm.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall DenoiseParameterForm::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@DenoiseParameterForm@@UAEHW4Call@QMetaObject@@HPAPAX@Z) 1>mainWindow.obj : error LNK2019: unresolved external symbol "public: static struct QMetaObject const MainWindow::staticMetaObject" (?staticMetaObject@MainWindow@@2UQMetaObject@@B) referenced in function "public: static class QString __cdecl MainWindow::tr(char const *,char const *)" (?tr@MainWindow@@SA?AVQString@@PBD0@Z) 1>mainWindow.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall MainWindow::metaObject(void)const " (?metaObject@MainWindow@@UBEPBUQMetaObject@@XZ) 1>mainWindow.obj : error LNK2001: unresolved external symbol "public: virtual void * __thiscall MainWindow::qt_metacast(char const *)" (?qt_metacast@MainWindow@@UAEPAXPBD@Z) 1>mainWindow.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall MainWindow::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@MainWindow@@UAEHW4Call@QMetaObject@@HPAPAX@Z) 1>statisticsDialog.obj : error LNK2019: unresolved external symbol "public: static struct QMetaObject const StatisticsDialog::staticMetaObject" (?staticMetaObject@StatisticsDialog@@2UQMetaObject@@B) referenced in function "public: static class QString __cdecl StatisticsDialog::tr(char const *,char const *)" (?tr@StatisticsDialog@@SA?AVQString@@PBD0@Z) 1>statisticsDialog.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall StatisticsDialog::metaObject(void)const " (?metaObject@StatisticsDialog@@UBEPBUQMetaObject@@XZ) 1>statisticsDialog.obj : error LNK2001: unresolved external symbol "public: virtual void * __thiscall StatisticsDialog::qt_metacast(char const *)" (?qt_metacast@StatisticsDialog@@UAEPAXPBD@Z) 1>statisticsDialog.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall StatisticsDialog::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@StatisticsDialog@@UAEHW4Call@QMetaObject@@HPAPAX@Z) 1>G:\xiaochen\projects\qt\Qt4PCLEditor\Win32\Release\\Qt4PCLEditor.exe : fatal error LNK1120: 16 unresolved externals
解决方法是将项目所有的头文件加入Headers中，并且在visual studio上加载正确版本的Qt Add-in。
Qt 4.8.6 PCL 1.8.0 VS 2010 联合编译常见错误
