###
### ----------------------------------------------------------------------------
### When cross compiling Erlang/OTP, copy this file and set the variables
### needed below. Then pass the path to the copy of this file as an argument
### to "eval `otp_build env_cross <absolute path to erl-xcomp.conf file>`".
### ----------------------------------------------------------------------------
### ----------------------------------------------------------------------------
### Variables in the following section *have* to be set.
###
##
## Target system. The value will be passed as '--host' argument to the configure
## script. It does not have to be a full CPU-VENDOR-OS tripplet, but can be. The
## full CPU-VENDOR-OS tripplet will be created by:
## $ERL_TOP/erts/autoconf/config.sub $erl_xcomp_host
##
erl_xcomp_host=
### ----------------------------------------------------------------------------
### To override the configure flags for a special target system, You
### can set this variable which overrides configure parameters on the
### command line and instead uses the specified options. The variable
### leaves the build-host system untouched.
### ----------------------------------------------------------------------------
erl_xcomp_configure_flags=
###-----------------------------------------------------------------------------
### You can specify a specific CC or LD for the build target (the cross
### compiler) here along with magic CFLAGS and/or LDFLAGS if needed
### ar and ranlib might also be specified if needed.
###-----------------------------------------------------------------------------
erl_xcomp_cc=
erl_xcomp_ld=
erl_xcomp_cflags=
erl_xcomp_cpp=
erl_xcomp_ldflags=
erl_xcomp_ranlib=
erl_xcomp_ar=
###-----------------------------------------------------------------------------
### The ded_ls and ded_ldflags variables control linking of dynamically loaded
### erlang drivers. On i.e. Linux these are set to
### $(CC) and "-shared" respectively, but other OS'es might need other
### programs and flags to build a dynamic library.
### erl_xcomp_ded_ld_runtime_library_path is the flag to set a
### specific runtime library path for the shared library at link time,
### usually this should be left empty.
###-----------------------------------------------------------------------------
erl_xcomp_ded_ld=
erl_xcomp_ded_ldflags=
erl_xcomp_ded_ld_runtime_library_path=
###
### 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.
###
##
## 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)
## 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 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)
## 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 - 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=
##
## 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=
