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:

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
