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:

+** NOTICE **
+The C++ global constructors do not link correctly when using non-shared
+libaries. This is probably the correct behavior of the linker, but I have
+not yet had time to devise a work around for it. The correct thing to
+do is add a reference to debSystem in apt-pkg/init.cc,
+assert(&debSystem == 0) would be fine for instance.
Guidelines
~~~~~~~~~~
required shims are OK.
Current shims:
- * C9x integer types 'inttypes.h'
- * sys/statvfs.h to convert from BSD/Linux statfs to SUS statvfs
+ * C99 integer types 'inttypes.h'
+ * sys/statvfs.h to convert from BSD/old-glibc statfs to SUS statvfs
* rfc2553 hostname resolution (methods/rfc*), shims to normal gethostbyname.
+ The more adventerous could steal the KAME IPv6 enabled resolvers for those
+ OS's with IPv6 support but no rfc2553 (why?)
+ * define _XOPEN_EXTENDED_SOURCE to bring in h_errno on HP-UX
+ * socklen_t shim in netdb.h if the OS does not have socklen_t
The only completely non-shimed OS is Linux with glibc2.1, glibc2.0 requires
-all three shims.
+the first three shims.

Debian GNU Linux 2.1 'slink'
Debian GNU Linux 'potato'
+Debian GNU Linux 'woody'
* All Archs
- Works flawlessly
- - You will want to have debiandoc-sgml and yodl installed to get
+ - You will want to have debiandoc-sgml and docbook2man installed to get
best results.
- - No IPv6 Support in glibc's < 2.1

Sun Solaris
SunOS cab101 5.7 Generic_106541-04 sun4u sparc
+ SunOS csu201 5.8 Generic_108528-04 sun4u sparc
- Works fine
- Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
OpenBSD
OpenBSD gsb086 2.5 CMPUT#0 i386 unknown
- - Works fine
- - OS needs 'ranlib' to generate the symbol table after 'ar'..
- - Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
-
+ OpenBSD csu101 2.7 CMPUT#1 i386 unknown
+ - OS needs 'ranlib' to generate the symbol table after 'ar'.. (not using
+ GNU ar with the gnu tool chain :<)
+ - '2.5' does not have RFC 2553 hostname resolution, but '2.7' does
+ - Testing on '2.7' suggests the OS has a bug in its handling of
+ ftruncate on files that have been written via mmap. It fills the page
+ that crosses the truncation boundary with 0's.

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
- configure attempts to detect items 2 and 3, and tries to fix them. If
- not, you can add the following into(patches welcome to configure.in)
- 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
+ configure should fix the last two (see above)
- Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
