#### --------------------------------------------------------------------------
#### When cross compiling Erlang/OTP using `otp_build', copy this file and set
#### the variables needed below. Then pass the path to the copy of this file as
#### an argument to `otp_build' in the configure stage:
#### `otp_build configure --xcomp-conf=<FILE>'
#### --------------------------------------------------------------------------
### Note that you cannot define arbitrary variables in a cross compilation
### configuration file. Only the ones listed below will be guaranteed to be
### visible throughout the whole execution of all `configure' scripts. Other
### variables needs to be defined as arguments to `configure' or exported in
### the environment.
### ---- `otp_build' only variables -------------------------------------------
### Variables in this section are only used, when configuring Erlang/OTP for
### cross compilation using `$ERL_TOP/otp_build configure'.
### NOTE! These variables currently have *no* effect if you configure using the
### `configure' script directly.
## erl_xcomp_build - Build system.
## This value will be passed as `--build=$erl_xcomp_build' argument to the
## `configure' script. It does not have to be a full CPU-VENDOR-OS triplet,
## but can be. The full CPU-VENDOR-OS triplet will be created by:
## `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_build'
## If `erl_xcomp_build=guess', the build system will be guessed using:
## `$ERL_TOP/erts/autoconf/config.guess'.
#erl_xcomp_build=
## erl_xcomp_host - Cross host system.
## This value will be passed as `--host=$erl_xcomp_host' argument to the
## `configure' script. It does not have to be a full CPU-VENDOR-OS triplet,
## but can be. The full CPU-VENDOR-OS triplet will be created by:
## `$ERL_TOP/erts/autoconf/config.sub $erl_xcomp_host'
#erl_xcomp_host=
## erl_xcomp_configure_flags - Extra configure flags.
## Extra flags to pass to the `configure' script.
#erl_xcomp_configure_flags=
### ---- Cross compiler and other tools to use --------------------------------
### If the cross compilation tools are prefixed by `<HOST>-' you probably do
### not need to set these variables (where `<HOST>' is what has been passed as
### `--host=<HOST>' argument to `configure').
## CC - C compiler.
#CC=
## CFLAGS - C compiler flags.
#CFLAGS=
## STATIC_CFLAGS - Static C compiler flags.
#STATIC_CFLAGS=
## CFLAG_RUNTIME_LIBRARY_PATH - C compiler runtime library path flag.
## This flag should set a specific runtime library path for the shared
## library at link time. Note that this is actually a linker flag, but it
## needs to be passed via the compiler.
#CFLAG_RUNTIME_LIBRARY_PATH=
## CPP - C pre-processor.
#CPP=
## CPPFLAGS - C pre-processor flags.
#CPPFLAGS=
## CXX - C++ compiler.
#CXX=
## CXXFLAGS - C++ compiler flags.
#CXXFLAGS=
## LD - Linker.
#LD=
## LDFLAGS - Linker flags.
#LDFLAGS=
## LIBS - Libraries.
#LIBS=
### -- Dynamic Erlang Driver linker flags --
### NOTE! Either set all or non of the DED_LD* variables.
## DED_LD - Linker.
#DED_LD=
## DED_LDFLAGS - Linker flags.
#DED_LDFLAGS=
## DED_LD_FLAG_RUNTIME_LIBRARY_PATH - Linker runtime library path flag.
## This flag should set a specific runtime library path for the shared
## library at link time.
#DED_LD_FLAG_RUNTIME_LIBRARY_PATH=
### -- Large file support --
### NOTE! Either set all or non of the LFS_* variables.
## LFS_CFLAGS - Large file support C compiler flags.
#LFS_CFLAGS=
## LFS_LDFLAGS - Large file support linker flags.
#LFS_LDFLAGS=
## LFS_LIBS - Large file support libraries.
#LFS_LIBS=
### -- Other tools --
## RANLIB - `ranlib' archive index tool.
#RANLIB=
## AR - `ar' archiving tool.
#AR=
## GETCONF - `getconf' system configuration inspection tool.
#GETCONF=
### ---- Cross System Root Locations ------------------------------------------
## erl_xcomp_sysroot - Absolute cross system root path.
## The absolute path to the system root of the cross compilation
## environment. Currently, the `crypto', `odbc', `ssh' and `ssl'
## applications need the system root. These applications will be skipped
## if the system root has not been set. The system root might be needed
## for other things too. If this is the case and the system root has not
## been set, `configure' will fail and request you to set it.
#erl_xcomp_sysroot=
## erl_xcomp_isysroot - Absolute cross include system root path.
## The absolute path to the system root for includes of the cross
## compilation environment. If not set, this value defaults to
## `$erl_xcomp_sysroot', i.e., only set this value if the include system
## root path is not the same as the system root path.
#erl_xcomp_isysroot=
### ---- Optional feature, or bug tests ---------------------------------------
### These tests cannot (always) be done automatically when cross compiling. You
### usually does not need to set these variables. Only set these if you really
### know what you are doing.
### Note that some of these values will override results of tests performed
### by `configure', and some will not be used until `configure' is sure that
### it cannot figure the result out.
### The `configure' script will issue a warning when a default value is used.
### When a variable has been set, no warning will be issued.
## erl_xcomp_bigendian - yes|no
## If `yes', the target system must be big endian. If `no', little endian.
## This can often be automatically detected, but not always. If not
## automatically detected, `configure' will fail unless this variable is
## set. No default value is used, i.e., `configure' will try to figure
## this out automatically.
#erl_xcomp_bigendian=
## erl_xcomp_linux_clock_gettime_correction - yes|no (defaults to `yes' on
## Linux; otherwise, `no')
## If `yes', `clock_gettime(CLOCK_MONOTONIC, _)' on the target system must
## work. This variable is recommended to be set to `no' on Linux systems
## with kernel versions less than 2.6.
#erl_xcomp_linux_clock_gettime_correction=
## erl_xcomp_linux_nptl - yes|no (defaults to `yes' on Linux; otherwise, `no')
## If `yes', the target system must have NPTL (Native POSIX Thread Library).
## Older Linux systems have LinuxThreads instead of NPTL (Linux kernel
## versions typically less than 2.6).
#erl_xcomp_linux_nptl=
## erl_xcomp_linux_usable_sigusrx - yes|no (defaults to `yes')
## If `yes', the `SIGUSR1' and `SIGUSR2' signals must be usable by the ERTS.
## Old LinuxThreads thread libraries (Linux kernel versions less than 2.2)
## used these signals and made them unusable by the ERTS.
#erl_xcomp_linux_usable_sigusrx=
## erl_xcomp_linux_usable_sigaltstack - yes|no (defaults to `yes' on Linux;
## otherwise, `no')
## If `yes', `sigaltstack()' must be usable on the target system.
## `sigaltstack()' on Linux kernel versions less than 2.4 are broken.
#erl_xcomp_linux_usable_sigaltstack=
## erl_xcomp_poll - yes|no (defaults to `no' on Darwin/MacOSX; otherwise, `yes')
## If `yes', the target system must have a working `poll()' implementation
## that also can handle devices. If `no', `select()' will be used instead of
## `poll()'.
#erl_xcomp_poll=
## erl_xcomp_kqueue - yes|no (defaults to `no')
## If `yes', the target system must have a working `kqueue()' implementation
## that returns a file descriptor which can be used by `poll()' and/or
## `select()'. If `no' and the target system has not got `epoll()' or
## `/dev/poll', the kernel-poll feature will be disabled.
#erl_xcomp_kqueue=
## erl_xcomp_putenv_copy - yes|no (defaults to `no')
## If `yes', the target system must have a `putenv()' implementation that
## stores a copy of the key/value pair.
#erl_xcomp_putenv_copy=
## erl_xcomp_reliable_fpe - yes|no (defaults to `no')
## If `yes', the target system must have reliable floating point exceptions.
#erl_xcomp_reliable_fpe=
## erl_xcomp_getaddrinfo - yes|no (defaults to `no')
## If `yes', the target system must have a working `getaddrinfo()'
## implementation that can handle both IPv4 and IPv6.
#erl_xcomp_getaddrinfo=
## erl_xcomp_gethrvtime_procfs_ioctl - yes|no (defaults to `no')
## If `yes', the target system must have a working `gethrvtime()'
## implementation and is used with procfs `ioctl()'.
#erl_xcomp_gethrvtime_procfs_ioctl=
## erl_xcomp_clock_gettime_cpu_time - yes|no (defaults to `no')
## If `yes', the target system must have a working `clock_gettime()'
## implementation that can be used for retrieving process CPU time.
#erl_xcomp_clock_gettime_cpu_time=
## erl_xcomp_after_morecore_hook - yes|no (defaults to `no')
## If `yes', the target system must have a working `__after_morecore_hook'
## that can be used for tracking used `malloc()' implementations core memory
## usage.
#erl_xcomp_after_morecore_hook=
## erl_xcomp_dlsym_brk_wrappers - yes|no (defaults to `no')
## If `yes', the target system must have a working `dlsym(RTLD_NEXT, <S>)'
## implementation that can be used on `brk' and `sbrk' symbols used by the
## `malloc()' implementation in use, and by this track the `malloc()'
## implementations core memory usage.
#erl_xcomp_dlsym_brk_wrappers=
