[okl4-developer] can't find some MACROS

[Carl van Schaik]

Hi Charles,

The tcb_layout.h and asmsysms.h files are autogenerated during the build
and should be in the build/pistachio directory.
These headers contain offsets into structures so that assembly code can
access C/C++ datastructures.

Since you seem to be having a problem compiling these files... MKASMSYM
is failing, leads me to think you have got the buildsystem or compiler
setup confused. What I think is happening is that the build system
should compile a asmsysm.c file to a assembly file, but should not do an
assemble stage.  It looks like for you its trying to run the assembler
over this file.

The asmsyms stuff is built with the AsmFile function in tools/build.py

this in turn uses  ASMCOM
in tools/toolchains.py for me, i see the line:
        self.dict["ASMCOM"] = "$CC -S $CC_PLAT_FLAGS $CPPFLAGS
$_CPPDEFFLAGS $_CPPINCFLAGS -c -o $TARGET $SOURCES"

... the "-S" flag is what causes the compiler to stop after outputting
the compiled assembly source

I hope this helps
