- General Information
- ~~~~~~~~~~~~~~~~~~~
- To compile this you need a couple things
- - A working POSIX system with working POSIX gcc, g++, make (GNU),
- ar, sh, awk and sed in the path
- - GNU Make 3.74 or so, -- normal UNIX make will NOT work
- * Note 3.77 is broken.
- - A working ANSI C++ compiler, this is not g++ 2.7.*
- g++ 2.8 works OK and newer egcs work well also. Nobody has tried it
- on other compilers :< You will need a properly working STL as well.
- - A C library with the usual POSIX functions and a BSD socket layer.
- If you OS conforms to the Single User Spec then you are fine:
- http://www.opengroup.org/onlinepubs/7908799/index.html
- Guidelines
- ~~~~~~~~~~
- I am not interested in making 'ultra portable code'. I will accept patches
- to make the code that already exists conform more to SUS or POSIX, but
- I don't really care if your not-SUS OS doesn't work. It is simply too
- much work to maintain patches for dysfunctional OSs. I highly suggest you
- contact your vendor and express intrest in a conforming C library.
- That said, there are lots of finniky problems that must be delt with even
- between the supported OS's. Primarily the path I choose to take is to put
- a shim header file in build/include that transparently adds the required
- functionality. Patches to make autoconf detect these cases and generate the
- required shims are OK.
- Current shims:
- * C9x integer types 'inttypes.h'
- * sys/statvfs.h to convert from BSD statfs to SUS statvfs
- * rfc2553 hostname resolution (methods/rfc*), shims to normal gethostbyname.
-
- The only completely non-shimed OS is Linux with glibc2.1
- Platform Notes
- ~~~~~~~~~~~~~~
- Debian GNU Linux 2.1 'slink'
- Debian GNU Linux 'potato'
- * All Archs
- - Works flawlessly
- - You will want to have debiandoc-sgml and yodl installed to get
- best results.
- - No IPv6 Support in glibc's < 2.1
- Sun Solaris
- SunOS cab101 5.7 Generic_106541-04 sun4u sparc
- - Works fine
- - Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
-
- HP-UX
- HP-UX nyquist B.10.20 C 9000/780 2016574337 32-user license
- - Evil OS, does not conform very well to SUS
- 1) snprintf exists but is not prototyped, ignore spurios warnings
- 2) No socklen_t
- 3) Requires -D_XOPEN_SOURCE_EXTENDED for h_errno
- Items 2 and 3 have to be fixed by hand. Insert this into
- build/include/netdb.h:
-
- #define _XOPEN_SOURCE_EXTENDED
- #define socklen_t size_t
- #include_next <netdb.h>
-
- A similar techinque can be used for snprintf/vsprintf if you dislike
- the warnings
- - Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
