Hi.
Here are the relevant details about the setup:
SunOS 4.1.4
gcc 2.7.2.2
tcp wrappers 7.5
egd 0.6 (doesn't really come into play at compile time)
The following only pertains to the compilation (and linking) stage.
Code and patches are SunOS specific.
-- The following functions are missing in SunOS: strerror, atexit,
memmove. I wrote simple replacements in term of on_exit and bcopy and
linked them without problem when necessary. (See code at end of
mail.)
-- The mail directory could not be deduced from any header file. In
addition, the MAIL environment variable was also not defined when
running configure. As a consequence, MAIL_DIRECTORY was just
#undef'ined in config.h and compilation of sshd.c failed. I recommend
adding and documenting an explicit --maildir configure option.
-- In packet.c, some IP TOS related constants are undefined. I
assumed the associated setsockopt calls were optional, but I may be
wrong. (See patch at end of mail.)
-- In ssh-agent.c, optind needs to be declared explicitly (it is not
in any header file). (See patch at end of mail.)
-- In scp.c, the SA_RESTART constant is undefined. SunOS is already
based on BSD signal semantics; do they also apply when using signal
functions from the POSIX interface? (See patch at end of mail.)
That's it for now.
