Note that such a request might cause a failure if the request cannot be satisfied. -### Pre-built Source Release ### - -The source release is delivered with a lot of platform independent -build results already pre-built. If you want to remove these pre-built -files, invoke `./otp_build remove_prebuilt_files` from the `$ERL_TOP` -directory. After you have done this, you can build exactly the same way -as before, but the build process will take a much longer time. - -> *WARNING*: Doing `make clean` in an arbitrary directory of the source -> tree, may remove files needed for bootstrapping the build. -> -> Doing `./otp_build save_bootstrap` from the `$ERL_TOP` directory before -> doing `make clean` will ensure that it will be possible to build after -> doing `make clean`. `./otp_build save_bootstrap` will be invoked -> automatically when `make` is invoked from `$ERL_TOP` with either the -> `clean` target, or the default target. It is also automatically invoked -> if `./otp_build remove_prebuilt_files` is invoked. - -### Building in Git ### - -When building in a Git working directory you also have to have a GNU `autoconf` -of at least version 2.59 on your system, because you need to generate the -`configure` scripts before you can start building. - -The `configure` scripts are generated by invoking `./otp_build autoconf` in -the `$ERL_TOP` directory. The `configure` scripts also have to be regenerated -when a `configure.in` or `aclocal.m4` file has been modified. Note that when -checking out a branch a `configure.in` or `aclocal.m4` file may change -content, and you may therefore have to regenerate the `configure` scripts -when checking out a branch. Regenerated `configure` scripts imply that you -have to run `configure` and build again. - -> *NOTE*: Running `./otp_build autoconf` is **not** needed when building -> an unmodified version of the released source. - -Other useful information can be found at our github wiki: -<http://wiki.github.com/erlang/otp> - -### make and $ERL\_TOP ### - -All the makefiles in the entire directory tree use the environment -variable `ERL_TOP` to find the absolute path of the installation. The -`configure` script will figure this out and set it in the top level -Makefile (which, when building, it will pass on). However, when -developing it is sometimes convenient to be able to run make in a -subdirectory. To do this you must set the `ERL_TOP` variable -before you run make. - -For example, assume your GNU make program is called `make` and you -want to rebuild the application `STDLIB`, then you could do: - - $ cd lib/stdlib; env ERL_TOP=<Dir> make - -where `<Dir>` would be what you find `ERL_TOP` is set to in the top level -Makefile. - -The Erlang/OTP Documentation ----------------------------- - -### How to Build the Documentation ### - -Before you can build the documentation you need to either [native build][] -or [cross build][] the Erlang/OTP system. After this you can build the -documentation as follows. - - $ cd $ERL_TOP - $ make docs - -The documentation can be installed either using the `install-docs` target, -or using the `release_docs` target. - -* If you have installed Erlang/OTP using the `install` target, install - the documentation using the `install-docs` target. Install locations - determined by `configure` will be used. `$DESTDIR` can be used the - same way as when doing `make install`. - - $ make install-docs - -* If you have installed Erlang/OTP using the `release` target, install - the documentation using the `release_docs` target. You typically want - to use the same `RELEASE_ROOT` as when invoking `make release`. - - $ make release_docs RELEASE_ROOT=<release dir> -#### Build Issues #### +### Running ### -We have sometimes experienced problems with Sun's `java` running out of -memory when running `fop`.

However, if configure does not -automatically enable SMP support, the build is very likely to fail. - -Use `./configure --disable-smp-support` if you for some reason do not -want to have the emulator with SMP support built. - -If SMP support is enabled, support for threaded I/O will also be turned on -(also in the emulator without SMP support). - -The `erl` command will automatically start the SMP emulator if the -computer has more than one logical processor. You can force a start -of the emulator with SMP support by passing `-smp enable` as -command line arguments to erl, and you can force a start of the -emulator without SMP support by passing `-smp disable`. - -GS (Graphic System) -------------------- - -GS now Tcl/Tk 8.4.
