Invoking 'cerl' like 'cerl -smp' would only start the smp emulator
if default was to start the non-smp emulator, otherwise 'erlexec'
would try to start 'beam.smp.smp'. Furthermore 'cerl -smp disable'
would be handled in the same way as 'cerl -smp'.
|
|
The -frag and -smp_frag options was used to start an (at the time)
experimental build of the emulator. The -shared and -hybrid option
was used to start experimental versions of the emulator with
alternate heap architectures.

Flow control can cause unwanted behaviour of the beam process,
if accidentally hit Ctrl-S (instead of Ctrl-D to detach) the
entire beam may be blocked.
Fix this problem by making it possible to turn off flow
control by setting the environment variable RUN_ERL_DISABLE_FLOWCNTRL.

Michael Santos supplied a very nice patch that did set the annotation level
correctly for gdb when run from cerl in emacs.
The patch adds --annotate=3 to the gdb command line, which makes emacs
parse the gdb output correctly, making the right source code be loaded in
the emacs buffer.
While integrating it, I removed my faulty code trying to do the same with hacky
elisp commands. Michaels way is the right way to do it.
Thanks!

Two related but slightly separate issues: run_erl doesn't support Solaris's
/dev/ptmx device and run_erl didn't load the necessary STREAMS modules so that
to_erl can provide terminal echo of keyboard input. This patch adds ifdef'd
support for Solaris and derivatives to open /dev/ptmx directly since adding
the C99 defines to CFLAGS breaks all kinds of other things in the build. It
also adds ifdef'd ioctl calls to load the necessary STREAMS modules to permit
termios to work.

While attempting to debug odd terminal echo issues on Solaris, I noticed that
run_erl.c will fail to compile due to a typo causing a syntax error.

This problems occurs in some recent versions of Emacs.

of the script
This patch will ensure the Install.src script to exit with the exit code 0
when the execution finished at the end of the script.
Originally from FreeBSD port patch.

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.

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)
