SysInfo cannot be compiled in Alpine Linux:
/home/buildbot/dvlp/cpp/code/upp/git/bazaar/SysInfo/SysInfo.cpp:1739:3: error: no matching function for call to 'reboot'
                reboot(0xfee1dead, 672274793, 0xCDEF0123);
                ^~~~~~
/usr/include/sys/reboot.h:15:5: note: candidate function not viable: requires 1 argument, but 3 were provided
int reboot(int);
    ^
/home/buildbot/dvlp/cpp/code/upp/git/bazaar/SysInfo/SysInfo.cpp:1749:3: error: no matching function for call to 'reboot'
                reboot(0xfee1dead, 672274793, 0x01234567);
                ^~~~~~
/usr/include/sys/reboot.h:15:5: note: candidate function not viable: requires 1 argument, but 3 were provided
int reboot(int);

The problem is here:
#if __GNU_LIBRARY__ > 5
		reboot(0xCDEF0123);
#else
		reboot(0xfee1dead, 672274793, 0xCDEF0123);
#endif

Alpine Linux is built around musl libc and __GNU_LIBRARY__ is undefined in it.

Thank you Novo

I have uploaded a fix. I do not know if Shutdown() function will work in Alpine Linux, but at least I hope it compiles now.


Best regards

There is another similar place to fix:
/home/buildbot/dvlp/cpp/code/upp/git/bazaar/SysInfo/SysInfo.cpp:1751:3: error: no matching function for call to 'reboot'                                                                           reboot(0xfee1dead, 672274793, 0x01234567);                                                                                                                                         ^~~~~~                                                                                                                                                             /usr/include/sys/reboot.h:15:5: note: candidate function not viable: requires 1 argument, but 3 were provided                                                                      int reboot(int);

There is a slightly different problem: it wont compile on Mac:
/Users/ssg/dvlp/cpp/code/upp/git/bazaar/SysInfo/SysInfo_in.h:48:11: fatal error: 'X11/Xlib.h' file not found
        #include <X11/Xlib.h>
                 ^~~~~~~~~~~~
1 error generated.

I believe it is supposed to compile on Mac because I see this:
#ifndef PLATFORM_OSX
	#include <sys/vfs.h>
#endif

I cannot answer. AFAIK SysInfo has never been tested in Mac.

EDIT: If you may confirm that it does not compile in Mac, I will add an explicit error message. Thank you.

It doesn't compile on Mac at this time.
X11/Xlib.h is not available on Mac.
