9301,Error when attempting to boot strap boost,Ben Key <BKey76@…>,,"Error when attempting to bootstrap boost

Hello,

I am getting the following error when attempting to run ""bootstrap.bat mingw.""

Building Boost.Build engine
builtins.c: In function 'builtin_readlink':
builtins.c:1879:39: error: 'FSCTL_GET_REPARSE_POINT' undeclared (first use in this function)
     int okay = DeviceIoControl(hLink, FSCTL_GET_REPARSE_POINT, NULL, 0, &buf, sizeof(buf), &n, NULL);
                                       ^
builtins.c:1879:39: note: each undeclared identifier is reported only once for each function it appears in

Failed to build Boost.Build engine.
Please consult bootstrap.log for further diagnostics.

This error does not happen with MSVC but it does happen with MinGW.

For both MinGW and MSVC, FSCTL_GET_REPARSE_POINT is defined in winioctl.h. However, this header file is not directly included in builtins.c. Only Windows.h is directly included in builtins.c.

This compiles for MSVC because winioctl.h is included by winscard.h which is in turn included by Windows.h. But winscard.h does not even exist in the MinGW header files and the MinGW version of Windows.h does not include winioctl.h. Thus winioctl.h is not indirectly included as it is in MSVC.

The solution is obvious. Do not assume that the header fill will be indirectly included as a side effect of including Windows.h. Instead modify builtins.c to directly include winioctl.h. With this one line change the error is resolved.",Bugs,closed,Boost 1.55.0,Building Boost,Boost Development Trunk,Showstopper,fixed,,
