72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	3 - Edit options.h to set which features you want.
9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	4 - Edit debug.h if you want any debug options (not usually required).

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	6 (If using a non-tarball copy, "autoconf; autoheader")

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	8 ./configure (optionally with --disable-zlib or --disable-syslog,
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	9 or --help for other options)

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	11 Now compile:

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	15 And install (/usr/local/bin is usual default):

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	19 (you can leave items out of the PROGRAMS list to avoid compiling them. If you
9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	20 recompile after changing the PROGRAMS list, you MUST "make clean" before

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	23 See MULTI for instructions on making all-in-one binaries.

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	25 If you want to compile statically, add "STATIC=1" to the make command-line.

9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	27 Binaries can be strippd with "make strip"

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	29 ============================================================================
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	30
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	31 Compiling with uClibc:
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	32
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	33 Firstly, make sure you have at least uclibc 0.9.17, as getusershell() in prior
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	34 versions is broken. Also note that you may get strange issues if your uClibc
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	35 headers don't match the library you are running with, ie the headers might
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	36 say that shadow password support exists, but the libraries don't have it.

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	38 Compiling for uClibc should be the same as normal, just set CC to the magic
9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	39 uClibc toolchain compiler (ie export CC=i386-uclibc-gcc or whatever).
9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	40 You can use "make STATIC=1" to make statically linked binaries, and it is
9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	41 advisable to strip the binaries too. If you're looking to make a small binary,
9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	42 you should remove unneeded ciphers and MD5, by editing options.h

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	44 It is possible to compile zlib in, by copying zlib.h and zconf.h into a
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	45 subdirectory (ie zlibincludes), and
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	46
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	47 export CFLAGS="-Izlibincludes -I../zlibincludes"

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	50 before ./configure and make.
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	51
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	52 If you disable zlib, you must explicitly disable compression for the client -
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	53 OpenSSH is possibly buggy in this regard, it seems you need to disable it
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	54 globally in ~/.ssh/config, not just in the host entry in that file.
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	55
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	56 You may want to manually disable lastlog recording when using uClibc, configure
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	57 with --disable-lastlog.

69 59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	59 One common problem is pty allocation. There are a number of types of pty
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	60 allocation which can be used -- if they work properly, the end result is the
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	61 same for each type. Running configure should detect the best type to use
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	62 automatically, however for some systems, this may be incorrect. Some
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	63 things to note:

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	65 If your system expects /dev/pts to be mounted (this is a uClibc option),
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	66 make sure that it is.
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	67
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	68 Make sure that your libc headers match the library version you are using.
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	69
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	70 If openpty() is being used (HAVE_OPENPTY defined in config.h) and it fails,
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	71 you can try compiling with --disable-openpty. You will probably then need
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	72 to create all the /dev/pty?? and /dev/tty?? devices, which can be
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	73 problematic for devfs. In general, openpty() is the best way to allocate
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	74 PTYs, so it's best to try and get it working.
