This sounds reminiscent of wanting to build for two different target
architectures?
We need to build for M68K and PPC target architectures and achieve this
by overriding the Tornado directory (if necessary) and the compiler line
in the CONFIG_SITE.Vx.$(T_A) files. For example:
------------------------------------------------------------------------
# $Id: CONFIG_SITE,v 1.4 1999/03/08 20:09:07 epics Exp $
.
(lots omitted)
.
VX_DIR_YES=/usr/local/vw/m5.3.1.base
------------------------------------------------------------------------
------------------------------------------------------------------------
# $Id: CONFIG_SITE.Vx.mv177,v 1.1 1998/10/21 21:31:37 epics Exp $
# This avoids having to define GCC_EXEC_PREFIX environment variable
GCC = GCC_EXEC_PREFIX=$(GNU_LIB)/gcc-lib/ $(GNU_BIN)/cc$(CMPLR_SUFFIX) -nostdinc
------------------------------------------------------------------------
------------------------------------------------------------------------
# $Id: CONFIG_SITE.Vx.mv2304,v 1.1 1999/03/08 20:09:55 epics Exp $
# For PPC Tornado, use appropriate VxWorks version
VX_DIR_YES=/usr/local/vw/m5.3.1.ppc
# This avoids having to define GCC_EXEC_PREFIX environment variable
GCC = GCC_EXEC_PREFIX=$(GNU_LIB)/gcc-lib/ $(GNU_BIN)/cc$(CMPLR_SUFFIX) -nostdinc
------------------------------------------------------------------------
