These variables currently have *no* effect if you configure using ## the `configure' script directly. # * `erl_xcomp_build' - The build system used. 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 $erl_xcomp_build'. If set to `guess', # the build system will be guessed using # `$ERL_TOP/erts/autoconf/config.guess'. erl_xcomp_build=guess # * `erl_xcomp_host' - Cross host/target system to build for. 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=`arch`-apple-iossimulator # * `erl_xcomp_configure_flags' - Extra configure flags to pass to the # `configure' script. erl_xcomp_configure_flags="--without-termcap --without-wx \ --without-javac --without-odbc \ --without-debugger --without-observer --without-cdv --without-et \ --enable-builtin-zlib --enable-static-nifs --enable-static-drivers" ## -- Cross Compiler and Other Tools ------------------------------------------- ## If the cross compilation tools are prefixed by `-' you probably do ## not need to set these variables (where `' is what has been passed as ## `--host=' argument to `configure'). ## All variables in this section can also be used when native compiling. export XCOMP_SDK=iphonesimulator export XCOMP_SDKROOT=`xcrun -sdk $XCOMP_SDK --show-sdk-path` export XCOMP_ARCH="-arch `arch`" # * `CC' - C compiler.

AR="xcrun -sdk $XCOMP_SDK ar" # * `GETCONF' - `getconf' system configuration inspection tool. `getconf' is # currently used for finding out large file support flags to use, and # on Linux systems for finding out if we have an NPTL thread library or # not. #GETCONF= ## -- Cross System Root Locations ---------------------------------------------- # * `erl_xcomp_sysroot' - The absolute path to the system root of the cross # compilation environment. Currently, the `crypto', `odbc', `ssh' and # `ssl' applications need the system root. These applications will be # skipped if the system root has not been set. The system root might be # needed for other things too. If this is the case and the system root # has not been set, `configure' will fail and request you to set it. erl_xcomp_sysroot=$XCOMP_SDKROOT # * `erl_xcomp_isysroot' - 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, and Bug Tests ------------------------------------------ ## These tests cannot (always) be done automatically when cross compiling. You ## usually do 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_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. # This is currently only used by unsupported features. #erl_xcomp_after_morecore_hook= # * `erl_xcomp_bigendian' - `yes|no'. No default. 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. Since no default # value is used, `configure' will try to figure this out automatically. #erl_xcomp_bigendian= # * `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_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_dlsym_brk_wrappers' - `yes|no'. Defaults to `no'. If `yes', the # target system must have a working `dlsym(RTLD_NEXT, )' 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. This is currently only used by unsupported features. #erl_xcomp_dlsym_brk_wrappers= # * `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_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_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_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 typically less than # 2.2) used these signals and made them unusable by the ERTS. #erl_xcomp_linux_usable_sigusrx= # * `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_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'.
