# LynxOS with g++.  Defaults to LynxOS Version 4.0.0.  For Version 4.2.0,
# for example, add "VERSION=4.2.0" to your make invocation.

#### NOTE:  It's best to create a file that includes this one, instead
#### of symlinking it.  That way, you can easily override the default
#### configuration.  For example, to configure for a PowerPC target, I
#### use a include/makeinclude/platform_macros.GNU that contains the
#### following lines (without comment markers):
####
####     LYNXTARGET = ppc
####     include $(ACE_ROOT)/include/makeinclude/platform_lynxos.GNU
####
#### Similarly, the default VERSION and HOST_OS settings (see below)
#### can be overridden for your particular platform.

  export VERSION=$(shell uname -r)

  # LynxOS's mkdir needs -f option to prevent it returning error
  # if directory already exists.
  ACE_MKDIR=mkdir -pf
else
  CROSS-COMPILE = 1

  #### The following may need to be customized for your host or target type.
  #### Or, you can source the appropriate (for your shell) Lynx SETUP file
  #### before running "make".
