Does not compile on Windows

[danvx6]

I'm unable to compile on Windows 10, which seems to be an issue with the library sys/select.h not existing on Windows. Is there an alternative?

In file included from include/Joystick.h:40, from src/Joystick.c:21: include/avr_mock.h:9:10: fatal error: sys/select.h: No such file or directory 9 | #include <sys/select.h> | ^~~~~~~~~~~~~~ compilation terminated. make: *** [Makefile:62: emulator_obj/Joystick.o] Error 1

Have a good day @danvx6 , the alternative is based on using winsock2.h instead of sys/select.h.

Thanks for the hint @sisco0.

I tried substituting winsock2.h in place of sys/select.h but that creates more errors because the functions inside are different. After a google search I found suggestion to change select() to FlushFileBuffers(), but that doesn't seem to work in this case and leaves other errors: c:\mingw\include\winbase.h:1610:42: note: expected 'HANDLE' {aka 'void *'} but argument is of type 'int' 1610 | WINBASEAPI BOOL WINAPI FlushFileBuffers (HANDLE); | ^~~~~~ gcc -o emulator emulator_obj/Joystick.o c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: emulator_obj/Joystick.o:Joystick.c:(.text+0x4f): undefined reference to__WSAFDIsSet@8' c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: emulator_obj/Joystick.o:Joystick.c:(.text+0xb4): undefined reference to select@20' collect2.exe: error: ld returned 1 exit status make: *** [Makefile:58: emulator] Error 1

At this point I may just try to compile in a linux vm since tbh I don't understand what is going on in the program enough to replace these functions with ones available to Windows.

Have a good day, you are obtaining linker errors, you should use -lws2_32 as a linking parameter. Even more, select function is the correct for both headers so no FlushFileBuffers function should be used.

By the way, I recommend you using WSL 2 (Windows Subsystem for Linux) feature of Windows in order to accomplish your task. It is a very convenient approach to integrate Linux under your Windows environment.

Thanks for all the help. I meant I used FlushFileBuffers in place of fsync, my mistake. After following your advice I was able to successfully compile Joystick.hex! Thank you!
