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	19 (you can leave items out of the PROGRAMS list to avoid compiling them. If you

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	26

b24730e11c83 add note about compiling for 386 Matt Johnston <matt@ucc.asn.au> parents: 72 diff changeset	32 CFLAGS=-DLTC_NO_BSWAP so that libtomcrypt doesn't use 486+ instructions.

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	37
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	38 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	39 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	40 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	41 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	43 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	44 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	45 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	46 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	47 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	49 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	50 subdirectory (ie zlibincludes), and

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	55 before ./configure and make.

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	57 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	58 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	59 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	61 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	62 with --disable-lastlog.

69 59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	64 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	65 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	66 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	67 automatically, however for some systems, this may be incorrect. Some
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	68 things to note:

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	70 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	71 make sure that it is.
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	72
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	73 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	74
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	75 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	76 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	77 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	78 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	79 PTYs, so it's best to try and get it working.
