VTM-19.0 not compiling when the macro REUSE_CU_RESULTS is equal to 0.

[dumas]

When VTM-19.0 is compiled with REUSE_CU_RESULTS at 0, several compilation errors appear.

ERROR LOG

COMPILATION ENVIRONMENT

---

OS : CentOS Linux 7 Cores
Compiler : GCC 8.3.1

OTHER TEST

---

The same error appears when compiling using Windows 11 and MSVC 16-19.29.

POTENTIAL FIX

---

In "EncModeCtlr.cpp", line 1874, "

cuECtx.get<bool>(IS_REUSING_CU)" can be wrapped by the macro REUSE_CU_RESULTS.

2. In "EncCfg.h", line 1580, the following code

#if REUSE_CU_RESULTS

ChromaFormat getChromaFormatIdc ( ) const { return m_chromaFormatIDC; }

#else

ChromaFormat getChromaFormatIdc ( ) { return m_chromaFormatIDC; }

#endif

can become

ChromaFormat getChromaFormatIdc ( ) const { return m_chromaFormatIDC; }

With 1. and 2., the compilation completes.
