the compilation time prompts: The object allocated on the heap may not be aligned 64

[lovecomputer888]

After using the following statement ReaderWriterQueue<int> q(100); , the compilation time prompts: The object allocated on the heap may not be aligned 64, I use MSVC（ver2022,c++14） to develop， how to solve it?

Can you post the full error message?

This code:dataQueue = new moodycamel::ReaderWriterQueue(1024); This is message: C4316 “moodycamel::ReaderWriterQueue<quint8,512>”: 在堆上分配的对象可能不是对齐 64

I have the same warning when use std::make_shared to create a object of moodycamel::BlockingReaderWriterQueuestd::string , or use std::make_shared to create a object who has an attribute of moodycamel::BlockingReaderWriterQueuestd::string。

For objects allocated on the heap this can be normal. It's not a problem if the alignment to 64 is not respected, it's just a hint to potentially improve performance. You can define MOODYCAMEL_MAYBE_ALIGN_TO_CACHELINE before including the header to remove the alignment and silence this warning, if you like.
