NormsIndexesTableType symbol errors

[tmontaigu]

The issue is more related to CloudCompare than this plugin but:

The type NormsIndexesTableType cannot be proberly wrapped to Python.

On linux if its wrapped or used in as an argument / return type at runtime we get such error:

libPythonPlugin.so does not seem to be a valid plugin	(Cannot load library /usr/local/lib/cloudcompare/plugins/libPythonPlugin.so: (/usr/local/lib/cloudcompare/plugins/libPythonPlugin.so: undefined symbol: _ZTI21NormsIndexesTableType))

Inspecting libQCC_DB_LIB.so indeed shows that the symbol is not exported.

nm -gD libQCC_DB_LIB.so  | grep _ZTI21NormsIndexesTableType
# nothing

The fix would be to put QCC_DB_LIB_API to the class:

# qCC_db\include\ccAdvancedTypes.h

// From
class NormsIndexesTableType : public ccArray<CompressedNormType, 1, CompressedNormType> { ... }

// To
class QCC_DB_LIB_API NormsIndexesTableType : public ccArray<CompressedNormType, 1, CompressedNormType> { ... }

However doing this creates link errors on windows about symbols being define multiple times (LNK2005, LNK1169) on std::vector methods

CloudCompare.exe : fatal error LNK1169: un ou plusieurs symboles définis à différentes reprises ont été rencontrés

It seems that It's due (not 100% sure) to the fact that CloudCompare has multiple classes that inherits from std::vector.
But then no idea on how to fix this without refactoring alot of CC's internals
