Required utilities
------------------
These are the tools you will need in order to unpack and build Erlang/OTP.
- Unpacking
- ---------
-
- GNU unzip, or a modern uncompress.
-
- A TAR program that understands the GNU TAR format for long
- filenames (such as GNU TAR).
-
-
- Compiling
- ---------
-
- GNU make
-
- GNU C compiler
-
- Perl 5
-
- GNU m4 If hipe (native code) support is enabled.
-
- ncurses (Or termcap or termlib.) The development headers and
- libraries are needed, often known as ncurses-devel.
- (Use --without-termcap to build without any of these
- libraries. Only the old shell (without any line
- editing) can be used.)
-
- OpenSSL Optional, but needed for building the Erlang/OTP
- applications 'ssl' and 'crypto'. You need the
- "development package" of OpenSSL, i.e. including
- the header files. For building the application 'ssl'
- the OpenSSL binary command program 'openssl' is also
- needed.
-
- At least version 0.9.7 of OpenSSL is required.
-
- Sun Java jdk-1.5.0 Or higher. Optional but needed for building
- the Erlang/OTP application 'jinterface' and parts
- of 'ic' and 'orber'. We have also tested
- IBM's JDK 1.5.0.
-
- X Windows Optional, but development headers and libraries
- are needed to build the Erlang/OTP application 'gs'
- on Unix/Linux.
-
- sed There seem to be some problems with some of the
- 'sed' version on Solaris. Make sure "/bin/sed"
- or "/usr/bin/sed" is used on the Solaris platform.
-
- Flex Optional, headers and libraries are needed to
- build the flex scanner for the megaco application
- on Unix/Linux.
-
-
- Installing
- ----------
-
- An 'install' program that can take multiple file names.
