Cross compiling for VxWorks/PowerPC Target from a Linux/x86 Machine

Cross compiling for VxWorks/PowerPC Target from a Linux/x86 Machine

[Arun Prasad Velu]

Hello,

I'd like to know how feasible is it to cross compile for a VxWorks/PowerPC
Target from a Linux/x86 Machine?
If there was any attempt earlier, I'd like to know about it (basically to
get the source compiled for VxWorks/PowerPC from Linux/x86 machine).
Any pointer on how to go about it would also be appreciated.

Thanks and Regards
Arun

You can get the gcc toolchain that WR is using, it is GPL and Wind River
will provide it free to people they've distributed the binaries to --
which should be everyone who's also bought a valid VxWorks library
license. If you want to use your off-the-shelf gcc it may be somewhat
tricky to configure your gcc just like it is in Tornado, but on an
existing Tornado installation (even on Windows) you can probably get gcc
to cough up most of the details of how it was configured if you want to
build your own cross-toolchain.

VxWorks AE has supported Linux cross-development hosts for quite some time.

VxWorks 6.0 (soon in beta) supports Linux development hosts (official
support for Red Hat Enterprise Linux 3 although it probably will work
with some tweaking on other distributions). Details at
http://www.windriver.com/announces/02232004b.html. It also is integrated
with Wind River Workbench, which uses Eclipse as an IDE framework for
the cross-toolchain, debugger, code browsing -- although it's still easy
to use the cross-toolchain from a command line build (that's what many
VxWorks architecture engineers do - we edit target/config/bsp/config.h
and fire off make). You also have your choice of two toolchains, gcc or
Wind Power Compiler.

I haven't tried mixing objects from another gcc toolchain, say DENX,
with objects from WR, but I don't see why (in principle) they wouldn't
work, although I'd expect caveats with specific assembler opcodes, link
operations, and especially C++ interoperation (the gcc and wpc
toolchains do not intermix C++ objects).

Cheers,
James

This is a bit dated, but may still hold some interesting bits for you:

I think http://vxtools.sourceforge.net/ is a good starting point.
The project is an attempt to make open source vxworks tools running on Linux
and have the link to the vxworks compiler sources.

A co-worker get the cross compiler source from WindRiver and built it under linux.  I wasn't involved and don't know any answers, but he said it was straight forward.  Note that "straight forward" does _not_ mean effortless, depending on your level of expertise, this will take between a day and forever, probably averaging 3-5 days.  This gets you everything you need to compile and link.

WindRiver's proprietary tools (their debugger and configuration system) aren't included, so you have to create your configuration (or at least an initial configuration) using their Windows/Solaris tools -- this produces prjConfig.h (IIRC) configuration file which you then copy to your linux platform and which you can edit by hand if you wish to reconfigure without Windows.  You can use gdb to debug (takes some effort to understand how to make it work) or use other methods (e.g. print statements) -- I generally use print statements.

Building on linux is vastly superior to the gross bloated IDE, but I'm biased -- I hate IDEs.
