windows下面编译失败
D:/Programming/InferLLM/src/file.h: In destructor 'inferllm::InputFile::~InputFile()': D:/Programming/InferLLM/src/file.h:36:13: error: 'munmap' was not declared in this scope 36 | munmap(m_mmap_addr, m_size); | ^~~~~~ ninja: build stopped: subcommand failed.
我尝试把mmpap换成了win下的等效函数然后把
if (m_enable_mmap) { int flags = MAP_SHARED; m_mmap_addr = mmap(NULL, m_size, PROT_READ, flags, m_fd, 0); INFER_ASSERT(m_mmap_addr != MAP_FAILED, "mmap failed."); madvise(m_mmap_addr, m_size, MADV_WILLNEED); }
注释掉了结果现在编译报错这个：

the compiler not support target attribute feature，maybe you should change the compiler to clang_cl
