fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	48 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	49 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	50 headers don't match the library you are running with, ie the headers might

9597c2e3b9d4 Some doc changes Matt Johnston <matt@ucc.asn.au> parents: 69 diff changeset	54 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	55 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	56 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	57 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	59 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	60 subdirectory (ie zlibincludes), and

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	71 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	72 with --disable-lastlog.

59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	75 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	76 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	77 automatically, however for some systems, this may be incorrect. Some
59d16db56e9f Simple text changes Matt Johnston <matt@ucc.asn.au> parents: 4 diff changeset	78 things to note:

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	80 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	81 make sure that it is.

fe6bca95afa7 Makefile.in contains updated files required Matt Johnston <matt@ucc.asn.au> parents: diff changeset	83 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	85 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	86 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	87 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	88 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	89 PTYs, so it's best to try and get it working.
