improvements.
Most notable:
Lots of cross compilation improvements. The old cross compilation
support was more or less non-existing as well as broken. Please,
note that the cross compilation support should still be
considered as experimental. Also note that old cross compilation
configurations cannot be used without modifications. For more
information on cross compiling Erlang/OTP see the
$ERL_TOP/xcomp/README file.
Support for staged install using <url
href="http://www.gnu.org/prep/standards/html_node/DESTDIR.html">D
ESTDIR</url>. The old broken INSTALL_PREFIX has also been fixed.
For more information see the $ERL_TOP/README file.
Documentation of the release target of the top Makefile. For more
information see the $ERL_TOP/README file.
make install now by default creates relative symbolic links
instead of absolute ones. For more information see the
$ERL_TOP/README file.
$ERL_TOP/configure --help=recursive now works and prints help for
all applications with configure scripts.
Doing make install, or make release directly after make all no
longer triggers miscellaneous rebuilds.
Existing bootstrap system is now used when doing make install, or
make release without a preceding make all.
The crypto and ssl applications use the same runtime library path
when dynamically linking against libssl.so and libcrypto.so. The
runtime library search path has also been extended.
The configure scripts of erl_interface and odbc now search for
thread libraries and thread library quirks the same way as erts
do.
The configure script of the odbc application now also looks for
odbc libraries in lib64 and lib/64 directories when building on a
64-bit system.
The config.h.in file in the erl_interface application is now
automatically generated in instead of statically updated which
reduces the risk of configure tests without any effect.

It is now possible to increase or decrease the maximum number of atoms
the VM can handle. The default value is 1048576 (1024*1024).

* cf/compile_warning_as_error:
Add option -Werror in erlc(1)
compile: add flag warnings_as_errors to treat warnings as errors
compile.erl: remove trailing whitespace
OTP-8382 The -Werror option for erlc and the compiler option
warnings_as_errors will cause warnings to be treated as errors.
(Thanks to Christopher Faulet.)

Like in gcc, this option treats warnings as errors.

* egil/binary-gc:
Add documentation for binary heap size settings.
Add tracing capabilities for binary virtual heap
Add min heap size start options to beam and erl
Improve binary garbage collection
OTP-8370 The default settings for garbage collection of binaries has been
adjusted to be less aggressive than in R13B03. It is now also
possible configure the settings for binary GC. See the
documentation for spawn_opt/2-5, erlang:system_info/1,
erlang:system_flag/2, process_flag/2-3, erlang:trace/3, and the
documenation for erl for the new command line options +hms and
+hmbs.
|
|
The erl (and beam) start arguments are extended with
the following options:
* +hms Size, sets the default minimum heap size
for processes.
* +hmbs Size, sets the default minimum binary virtual heap
size for processes.
The previous +h Size argument can still be used for backward
compatibility purposes.

The eval call in these scripts was failing for me because the path to
them on my windows machine contained spaces. I also fixed some
copy/paste-os from when (evidently) the mc.sh script was created by
copying the rc.sh script and modifying it.
|
|
* mh/to_erl-error-messages:
to_erl: Include strerror(errno) in error messages
OTP-8325 to_erl will now include the system error string in error messages
to make it easier to understand what the real problem is. (Thanks
to Magnus Henoch.)

to_erl likes to print the message "No running Erlang on pipe ...",
no matter what the problem actually was. The wording might make
you forget that you just need to run to_erl as another user,
for example.
With this change, to_erl will print the system error message
in addition to its own.
Example output:
No running Erlang on pipe pipes/erlang.pipe.5: Permission denied
(wrong user, wrong permissions, etc)
No running Erlang on pipe pipes/erlang.pipe.5: No such device or address
(this actually means "no running Erlang")
No running Erlang on pipe pipes/erlang.pipe: No such file or directory
(not only is there no running Erlang, there are also no pipes at all)

The wx application will only work in the SMP emulator,
so the -wx option for 'dialyzer' must force the -smp
option when starting the emulator.
Make sure that -wx in *any* position on the command
line (not only as the first argument) forces the
SMP emulator.
