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=yes + +# * `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'.

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. 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'.

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'.
