VTM 7.0rc1 fails to build under Visual Studio

[jonathang]

Attempting to build under Visual Studio 2019 (CMakeLists.txt opened directly from Visual Studio) fails with the following linker errors:

C:\Software\EncApp.cpp.obj : error LNK2019: unresolved external symbol "public: __cdecl EncTemporalFilter::EncTemporalFilter(void)" (??0EncTemporalFilter@@QEAA@XZ) referenced in function "public: void __cdecl EncApp::encode(void)" (?encode@EncApp@@QEAAXXZ)

The build error is introduced by commit fe8e3e68fef2be5973662b601b5035987bfc4cbd: Merge branch 'JVET-O0549_ENCODER_ONLY_FILTER' into 'master'

I was not able to recreate this problem using Visual Studio 2019 16.3.7. I opened "File->Open->CMake" and it built just fine.

Looks like this isn't a clean build. When source files are added the cmake cache should be cleared before building.

You are right, I did not clear my cmake cache. It was achieved by "Project->CMake Cache->Delete Cache". Thanks!

Please close the ticket.
