The error message you're seeing in the build log indicates that the build process failed due to a missing header file:
fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory
The unistd.h header is a POSIX header file and is not available on Windows by default, which is why MSBuild cannot find it. This file typically provides access to the POSIX operating system API, and its absence suggests that the code is using POSIX-specific functions that are not available or are named differently on Windows.
To resolve this issue, you have a few options:
Conditional Compilation: If the code that includes unistd.h is not needed on Windows, you can exclude it using preprocessor directives. For example:
#ifndef _WIN32
#include <unistd.h>
#endif
Find Windows Alternatives: If the code in fileProcessor.cpp uses functions from unistd.h (like read, write, close, etc.), you will need to find the equivalent Windows functions and use them when compiling on Windows.
Use a Compatibility Layer: There are libraries like unistd.h for Windows, which provide a compatibility layer for Unix-like functions on Windows. You can include such a library in your project to bridge the gap.
Refactor the Code: If the POSIX-specific code is not essential, you could refactor the code to be cross-platform, avoiding the use of unistd.h altogether.
