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

21 PORTING NOTES AND COMMENTS
22 --------------------------
23
24 To port smartmontools to the OS of your choice, please:
25
26 [0] Contact smartmontools-support@listi.jpberlin.de to check
27 that it's not already been done.
28
29 [1] Make copies of os_generic.h and os_generic.cpp called os_myOS.h
30 and os_myOS.cpp .
31
32 [2] Modify configure.in so that case "${host}" includes myOS.
33
34 [3] Verify that ./autogen.sh && ./configure && make compiles the
35 code. If not, fix any compilation problems. If your OS lacks
36 some function that is used elsewhere in the code, then add a
37 AC_CHECK_FUNCS([missingfunction]) line to configure.in, and
38 surround uses of the function with:
39 #ifdef HAVE_MISSINGFUNCTION
40 ...
41 #endif
42 where the macro HAVE_MISSINGFUNCTION is (or is not) defined in
43 config.h.
44
45 [4] Now that you have a working build environment, you have to
46 replace the 'stub' function calls provided in this file.
47
48 Provide the functions defined in this file by fleshing out the
49 skeletons below.
50
51 [5] Contact smartmontools-support@listi.jpberlin.de to see
52 about checking your code into the smartmontools CVS archive.

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