22: NOTE: The code in this file is only called when smartmontools has
23: been compiled on an unrecognized/unsupported platform. This file
24: can then serve as a "template" to make os_myOS.cpp if you wish to
25: build support for that platform.

28: PORTING NOTES AND COMMENTS
29: --------------------------
30:
31: To port smartmontools to the OS of your choice, please:
32:
33: [0] Contact smartmontools-support@lists.sourceforge.net to check
34: that it's not already been done.
35:
36: [1] Make copies of os_generic.h and os_generic.cpp called os_myOS.h
37: and os_myOS.cpp .
38:
39: [2] Modify configure.in so that case "${host}" includes myOS.
40:
41: [3] Verify that ./autogen.sh && ./configure && make compiles the
42: code. If not, fix any compilation problems. If your OS lacks
43: some function that is used elsewhere in the code, then add a
44: AC_CHECK_FUNCS([missingfunction]) line to configure.in, and
45: surround uses of the function with:
46: #ifdef HAVE_MISSINGFUNCTION
47: ...
48: #endif
49: where the macro HAVE_MISSINGFUNCTION is (or is not) defined in
50: config.h.
51:
52: [4] Now that you have a working build environment, you have to
53: replace the 'stub' function calls provided in this file.
54:
55: Provide the functions defined in this file by fleshing out the
56: skeletons below. You can entirely eliminate the function
57: 'unsupported()'.
58:
59: [5] Contact smartmontools-support@lists.sourceforge.net to see
60: about checking your code into the smartmontools CVS archive.

64: Developer's note: for testing this file, use an unsupported system,
65: for example: ./configure --build=rs6000-ibm-aix && make
