Building GCC for Cortex

[John Hind]

I am trying to follow the tutorial "Building GCC for Cortex", but I am new
to Ubuntu and am running into the sand at Step 1 (the easiest step!). As it
has already taken me several hours of head-banging to get this far, I am
appealing for help!

The problem starts with the "make all" step (for binutils). It terminates
with "make: *** [all] Error 2". A few lines above this there are 5
occurrences of "tc-arm.c: xxxx: error: format not a string literal and no
format arguments".

I have tried the complete procedure to this point several times, with both
the latest release (binutils-2.19.1.tar.bz2) and the recommended one
(binutils-2.19.tar.bz2) always with the same result. This on a fresh
installation of Ubuntu 8.10 Desktop.

Anyone solved this one before or do I need to do some more head-banging?

I got the same problem some time ago. The bug and the fix is descripted
here:

Yes, but after I did that I remembered that gas didn't work properly with
Thumb2 anymore (no idea why), giving some errors about invalid assembler
statements. The only things that seems to work is 2.19.50.

Best,
Bogdan

Hay Ho! I ran into this one (the assembler errors) too. I decided yesterday
to start again with the exact versions recommended by Bogdan, but ran into
the sand again last night and was firmly told to drop it before I gave
myself an aneurism. Not wishing to stoke up the Linux fans out there, I am
beginning to remember why I am a die-hard Windows user. My first Lua build
in VS5 took less than 10 minutes from downloading the sources! I've said it
before and I'll say it again: "Life is too short for command lines!" (Rant
over - now I'll try again)

 

Thanks Bogdan and Joern for your help!

 

Update: I'm still seeing the same problem as last night - "sudo make
install" for newlib terminates Error 2 and further up there are messages
"arm-elf-ranlib: command not found", but typing "arm-elf-ranlib" at the
command prompt prints help information on that command - so it IS there.
This really has me baffled and it did not happen on the last attempt.

 

Any thoughts on this?

Yes: check the eluaproject.net webpage :) It says this (in
http://eluaproject.net/en/Building_GCC_for_Cortex):

On my system, the last line above (sudo make install-gcc) terminated with
errors, because it was unable to find our newly compiled binutils. *If this
happens for any kind of "make install" command*, this is a quick way to
solve it:


 $ sudo -s -H

# export PATH=/usr/local/cross-cortex/bin:$PATH
# make install-gcc
# exit


On the other hand, I agree that trying to compile the binutils/gcc/newlib
combo is a huge PITA, and this it should've been much better by now (given
the fact that the combo is old and widely used), but apparently this is the
best we have for now. On the bright side, once you get the hang of it,
you'll be able to amaze your friends with your newly acquired skills :D

Bogdan

Thanks again Bogdan, I actually got there just ahead of you - remembered the
advice from Ikea "if all else fails, read the instructions - again!"

 

Any idea *why* this works? (And is only needed *sometimes*?) There seems no
obvious connection between the symptoms and the solution! If you are
revising the instructions, might it be better to just do all the operations
requiring sudo this way, or maybe even do the entire process in a root
terminal?

 

I finally made it to the end - now to see if I can build eLua!

 

Any thoughts on running this toolchain in Eclipse? I'd like to get out of
"command line hell" ASAP!

It's not sometimes, it's just on "some systems". I tried to understand why
this happens a while ago, and I think the conclusion was that "sudo" can be
compiled in two ways: to inherit the environment of the calling process, or
not. Apparently, on Ubuntu it is compiled not to inherit the environment of
the calling process, hence the problem.

Sorry, can't help there. I love the command line, and in fact more than 95%
of eLua is written with vim :)

It's not sometimes, it's just on "some systems". I tried to understand why

compiled in two ways: to inherit the environment of the calling process, or
not. Apparently, on Ubuntu it is compiled not to inherit the environment of

For me, sudo worked fine for all the install steps EXCEPT Newlib, and it
worked fine even for Newlib when I was using the later version. I was
impressed by the ease of installation of Ubuntu, but they seem to have
created an even more annoying lock-down system than Vista, and that takes
some doing!

Sorry, can't help there. I love the command line, and in fact more than 95%
of eLua is written with vim :)

Now I'm suspecting you of masochistic tendencies :}

This is indeed strange, and I don't have an explanation for it. Might be a
matter of specifying the full paths in the automatically generated
installation script, this way you won't need a properly set PATH. And maybe
different versions of Newlib do this differently, or don't do it at all and
rely solely on the PATH.

:) Not at all actually, it just happens that "vim" is the most powerful text
editor I know of (on par with Emacs, but I like vim better). And I'm not
even what you'd call an "advanced vim user", but even with my not-so-great
vim knowledge, I can persuade him to perform some very powerfull magic for
my benefit :)

Bogdan
