Erlang/OTP 17.1 is a service release on the 17 track with mostly bug
fixes, but it does contain a number of new features and characteristics
improvements as well.
Some highlights of the release are:
- crypto: Add aes_cfb8 cypher to crypto:block_encrypt and block_decrypt.
- diameter: Add result code counters for CEA, DWA, and DPA.
- erts: The following built in functions in the erlang and binary modules
now bump an appropriate amount of reductions and yield when out of
reductions:
binary_to_list/1, binary_to_list/3, bitstring_to_list/1,
list_to_binary/1,
iolist_to_binary/1, list_to_bitstring/1, binary:list_to_bin/1
- hipe: Handle Maps instructions get_map_elements, put_map_assoc,
put_map_exact in the HiPE native code compiler.
- mnesia: The time for inserting locks for a transaction with large
number of locks is reduced significantly.
- ssh: Option max_sessions added to ssh:daemon/{2,3}.
- stdlib: Add maps:get/3 to maps module. The function will return the
supplied default value if the key does not exist in the map.

To build and use the buildroot stuff, do the following:
1) run 'make menuconfig'
2) select the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) Use your shiny new root filesystem. Depending on which sort of
root filesystem you selected, you may want to loop mount it,
chroot into it, nfs mount it on your target device, burn it
to flash, or whatever is appropriate for your target system.
You do not need to be root to build or run buildroot. Have fun!
Offline build:
==============
In order to do an offline-build (not connected to the net), fetch all
selected source by issuing a
$ make source
before you disconnect.
If your build-host is never connected, then you have to copy buildroot
and your toplevel .config to a machine that has an internet-connection
and issue "make source" there, then copy the content of your dl/ dir to
the build-host.
Building out-of-tree:
=====================
Buildroot supports building out of tree with a syntax similar
to the Linux kernel. To use it, add O=<directory> to the
make command line, E.G.:
$ make O=/tmp/build
And all the output files (including .config) will be located under /tmp/build.
More finegrained configuration:
===============================
You can specify a config-file for uClibc:
$ make UCLIBC_CONFIG_FILE=/my/uClibc.config
And you can specify a config-file for busybox:
$ make BUSYBOX_CONFIG_FILE=/my/busybox.config
To use a non-standard host-compiler (if you do not have 'gcc'),
make sure that the compiler is in your PATH and that the library paths are
setup properly, if your compiler is built dynamically:
$ make HOSTCC=gcc-4.3.orig HOSTCXX=gcc-4.3-mine
Depending on your configuration, there are some targets you can use to
use menuconfig of certain packages. This includes:
$ make HOSTCC=gcc-4.3 linux-menuconfig
$ make HOSTCC=gcc-4.3 uclibc-menuconfig
$ make HOSTCC=gcc-4.3 busybox-menuconfig
