I don't understand how to build EPICS for MVME3100. I have no problem
with mcp750, mvme2100, 68040, or 68060. I am trying to build EPICS
3.14.11 and am using vxWorks 5.5.1 with Tornado 2.2.1. If I put
vxWorks-mpc8540 in my list of CROSS_COMPILER_TARGET_ARCHS, I get
compile errors which I traced to ARCH_DEP_CPPFLAGS which is set to
-DCPU=PPC32 which the compiler does not recognize. If I change that to
ARCH_DEP_CPPFLAGS = -DCPU=PPC85XX, then I no longer get compile
errors, but EPICS will not load due to a lot of undefined symbols. I
talked to WRS about this problem and was advised that I was using the
wrong compiler. When I use Tornado to build vxWorks, Tornado uses
/home/als2/devel/vxWorks/tornado2.2.1-ppc/host/gnu/3.3/sun4-solaris2/bin/ccppc,
but when building EPICS, the EPICS build system uses
/home/als2/devel/vxWorks/tornado2.2.1-ppc/host/sun4-solaris2/bin/ccppc,
so, apparently, the EPICS build system does not automatically setup to
use the correct tools when specifying the target
vxWorks-mpc8540. What needs to be done to make this work right? Thanks.
