# VxWorks 7

# Building ACE for VxWorks 7
#
# Unlike earlier versions, VxWorks 7 requires a VSB before application code
# can be compiled (either kernel mode or RTP).  See the VxWorks documentation
# for information on creating a VSB (VxWorks Source Build).
#
# Create the file ace/config.h containing #include "ace/config-vxworks.h"
# Create the file include/makeinclude/platform_macros.GNU containing...
# VSB_DIR = <<absolute path to the VSB directory for the target system>>
# TOOL = gnu
# HOST_ROOT = <<location of host tools if using tao_idl, etc.>>
# << add other build settings here (debug, optimize, inline, rtp) >>
# include $(ACE_ROOT)/include/makeinclude/platform_vxworks.GNU
#
# Use the wrenv script for your host system to start a VxWorks development shell
# and build ACE from that shell using the normal procedure (set ACE_ROOT,
# generate makefiles if necessary, etc.).
#
# Not all configurations supported on VxWorks 6.x have been brought forward
# to this file.  If you are building a configuration that has not yet been
# attempted on VxWorks 7, this file may need to be changed.
