[ECOS] Building a toolchain for LEON

[ECOS] Building a toolchain for LEON

[Michele Portolan]

Does anyone knows how to build a toolchain for running eCos on the LEON
processor?
I do not seem able to find the correct TARGET for the "configure"
command....
Thanks,

Portolan Michele

Have you tried:

http://www.gaisler.com/leccs.html

Precompiled binaries and some documentation.

Thank you for the hint.
I tried with leccs but it just doesn't seem to want to work!
I followed all instructions, but in /opt/rtems/bin all files all called
something like "sparc-rtems-gcc" and are therefore not used. I created
simbolic links for all of them (like "ln sparc-rtems-gcc gcc") and put
/opt/rtems/bin at the head of my path.
Then, ecos/configure runs just nice, recognizing both C and C++ compilers as
cross-platform, but make stops at the very first compilation
(ecos/host/infrs/asser.cxx) saying:

in function 'void default_handler(const char *, unsigned int, const char
*)':
ecos/host/infrs/asser.cxx:254: implicit declaration of function 'int
mkstemp(...)'
ecos/host/infrs/asser.cxx:260: implicit declaration of function 'int
close(...)'

I'm using Cygwin under WIN98

Thank you very much,

Michele Portolan

I don't know what you're trying to do here but it looks wrong to me. Try to
do the following.

'sparc-rtems' is the correct toolchain to use for Leon, which I guess is
what 'leccs' gives you. Put the appropriate 'bin' directory in your path.
Don't do any symbolic links.
Don't run 'configure'
Make sure ECOS_REPOSITORY environment variable is set correctly to point to
the root of the eCos source tree 'packages' directory
Put the location of the command line 'ecosconfig' tool in your path.
Do the following (using command line tools) in a clean directory:

ecosconfig new leon
ecosconfig tree
make

[ECOS] R: [ECOS] R: [ECOS] Building a toolchain for LEON

[Michele Portolan]

Shouldn't I compile and install eCos sources before?
Up to now I have just the cvs repository and I am trying to compile and
install it, I don't have a ecosconfig yet.
Is my error trying to use the cross-compiler gcc instead of the classical
pre-installed one?
Sorry for all these silly question, but I am stilla beginner, as you should
have noticed!

RE: [ECOS] R: [ECOS] R: [ECOS] Building a toolchain for LEON

[Robert Cragie]

> Shouldn't I compile and install eCos sources before?

'Installing' eCos sources is simply unzipping a snapshot or getting it from
CVS. The 'packages' subdirectory then becomes your 'repository'. The command
line configuration tool builds a set of Makefiles for your target. Then you
simply run 'make' to build the target library, which you then link with your
application - the Makefiles will pick the appropriate sources from the
repository.

You can either build the configuration tool yourself using native gcc or
download a pre-built binary - I have always used a pre-built binary on
Linux. Alternatively you can use the GUI based configuration tool. See the
website for more details.

> Up to now I have just the cvs repository and I am trying to compile and

That's where you're going wrong. Reading 'configure.in' and 'README.host'
may help you understand more.

> Is my error trying to use the cross-compiler gcc instead of the classical
> pre-installed one?

You only need the native compiler to build the configuration tools (as
mentioned, you can alsoget these prebuilt from the eCos website). You need
the cross-compiler when you run 'make' as I have described.

Hope this helps

[ECOS] R: [ECOS] R: [ECOS] R: [ECOS] Building a toolchain for LEON

[Michele Portolan]

Thank you very much, without you I would have never got a hang on those
things!
I was really "drowned" by all those READMEs and documentations contradicting
one with the other
General informations like that are really diffucult to find, they are always
taken for granted.
