Erlang/OTP October 15, 2002 LAST MINUTE INFORMATION -- Release of Erlang 5.2/OTP R9B 1. GENERAL ------- 1.1 Installation Guide The installation guide can be found in /doc/installation_guide/part_frame.html 1.2 Java The Java sources where compiled using JDK 1.2.2. 1.3 Disk space An installation of Erlang/OTP needs approximately 110 MB of disk space. 1.4 The package contains HTML documentation. You can also get this documentation preformatted for printing in PDF format from http://www.erlang.se/doc/ This site also contains HTML documentation for older releases as a reference. 1.5 You don't need to recompile your Erlang object file (BEAM files) that was compiled with the R7B or R8B compiler but doing so may give you some performance improvements. 1.6 This release differs from earlier releases in that it contains several unsupported features for tryout. Most notably the sun-sparc-solaris 32 bit version contains support for HiPE native code compiling and loading. All platforms except Windows also contain an emulator using a shared (global) heap. Running 'erl -shared' starts this emulator. Note that no support is given on HiPE or the shared heap emulator, they are delivered for testing purpouses and should not be used in a production environment. Information about HiPE can be found at this site: http://www.csd.uu.se/projects/hipe/ 2. KNOWN BUGS AND PROBLEMS ----------------------- In the 64bit sparc-sun-solaris release, the following applications are still not converted to the 64bit environment: ic (the libraries) ssl erl_interface crypto odbc The 32bit versions can in most cases be used as a replacement. 3. NOTES ABOUT THE SOLARIS VERSION ------------------------------- 3.1 There are two sun-sparc-solaris versions, one for 32bit environment and one built for a 64bit environment (see "KNOWN BUGS AND PROBLEMS" above). If one hasn't special need for the 64bit address space, the 32bit version is in all senses to be preferred. The 64bit version consumes roughly twice the amount of memory and is not performing as well as the 32bit version in terms of speed. 3.2 HiPE native code loading is enabled by default, but compiling to native code is not supported in the sense that our support department can give no help on subjects due to native code compiling. 4. NOTES ABOUT THE WIN32 VERSION ----------------------------- 4.1 Some graphical tools still have problems on Windows. Pman may not start at the first attempt. Some other tools may give some error messages. 5. NOTES ABOUT THE VXWORKS VERSION ------------------------------- 5.1 The platform VxWorks is discontinued in the sense that only the libraries (erl_interface and ic's libraries) are supported. Running the erlang emulator on VxWorks is still possible but it's no longer maintained. The VxWorks release is still packaged as a full release and the emulator runs, but no support will be available for anything but the communication libraries. 6 NOTES ABOUT THE LINUX VERSIONS ----------------------------- 6.1 The following linux distributions/version combinations are supported and tested: i386: RedHat 7.1 x86 updated to kernel 2.4.5, glibc 2.2.2, and jdk 1.3.1_01. To run this Java version with this configuration you also need an older library installed with the RPM "compat-libstdc++-6.2-2.9.0.14.i386.rpm". Powerpc:Montavista Linux 2.1 Kernel 2.4.17, glibc 2.2.3, jdk 1.2.2. (Also tested with Kernel 2.4.18 and glibc 2.2.5) Sparc: Kernel 2.4.19, libc 2.1.3, jdk 1.3.0. 7. APPLICATIONS NOTES ------------------ 7.1 The 'comet' application is no longer part of the Erlang/OTP distribution. It's still available as an unsopported user contribution. 8.
