The severity code indicates that the project file line prohibits the display of status errors. C1047 object or library file ".Lib" is different from other objects (such as "x64\release\main.obj")

severity Code explain project file That's ok Disable status
error C1047 Object or library file “.\lib\SceneTempCal.lib” Yes use with other objects ( Such as “x64\Release\main.obj”) Created by different compiler versions ; Please regenerate all objects and libraries using the same compiler SceneTest E:\osg\work\ThermalCharacteristics_20220628\SceneTest\LINK 1

One 、 The reason for the error

VS2019 Development , I used it all the time debug Pattern , The code compilation is normal

Recently changed to Release Pattern , This error occurs as soon as you compile ：

LINK : fatal error C1047: Object or library file “.lib” Yes use with other objects ( Such as “x64\Release\main.obj”) Created by different compiler versions ; Please regenerate all objects and libraries using the same compiler

I searched the Internet , be supposed to ：

“ I also encountered this problem these days , Use what others have provided lib, stay vs2019 Next   debug Mode can run , but release Not in mode , The same mistake you made . At first I thought it was lib Are not compatible , Finally, I found this lib stay LTCG Cannot be parsed , Make the following corrections ：

Release In mode -> Configuration properties -> senior -> Whole program optimization -> Use link time code generation Put the default here “ Use link time code generation ” Change it to “ No full program optimization ”. Then you can run .

Generally, it is generated in the lower version lib Can be used by high-level compilers , This is the foundation of compatibility , ha-ha ！”

therefore Change the attribute , Change it to Without full program optimization , Will report another error , I thought I couldn't go on like this , It must have gone somewhere .

Later, it was upgraded VS2019 Well ,

Recompile after upgrade It also suggests this mistake ,

But this time After no full program optimization is removed from the attribute Recompile and pass .

Don't understand , One lib library How can there be such a situation when compiling ？

Make a note of ,
