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).

8f88f4290b22 document --enable-static in place of STATIC=1 Matt Johnston <matt@ucc.asn.au> parents: 443 diff changeset	27 By default Dropbear adds various build flags that improve robustness

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	41
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	42 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	43 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	44 headers don't match the library you are running with, ie the headers might

72 9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	47 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	48 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	49 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	50 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	51 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	53 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	54 subdirectory (ie zlibincludes), and

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	61 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	62 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	63 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	65 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	66 with --disable-lastlog.

69 59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	68 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	69 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	70 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	71 automatically, however for some systems, this may be incorrect. Some
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	72 things to note:

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	74 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	75 make sure that it is.
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	76
fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	77 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	79 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	80 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	81 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	82 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	83 PTYs, so it's best to try and get it working.
