Re: error building gcc , (simulators and targets...)

[Michael Elizabeth Chastain]

It is happening to multiple people.  It also happened to Johan Vermeire
as well (PR gdb/915).  Johan also got stuck because his MS Win2K + IE
6.0 browser couldn't file a bug report, and then nobody looked at his
mail to gdb-bug@gnu.org.

Preventing PR's with better doco is a good thing, both for the users
and for us.

Better doco will help our direct users, and then our channel partners,
partners, the cross-gcc FAQ people, can uptake our new doco or refer to
it in their doco.  That part won't happen overnight.  The most recent
cross-gcc FAQ I've seen is from 1999!

(Honestly, I think gdb could benefit from lots of re-engineering for
our customer-facing business processes, I'm reading a Patricia Seybold
book and all this goobledygook actually does apply to the gdb project,
in my mind at least).

So I'll write that doco and submit it soon.

This is what I've used.

http://www.sthoward.com/CrossGCC/FAQ-4.html

I feel that all the docs I've read tell me good stuff, but they don't tell 
things "step by step" , like I need , because I'm a real begginner, and I 
can't overcome easily each problem I find.

Thank you!

Re: error building gcc , (simulators and targets...)

I made four directories for building Binutils , GCC , Newlib and Gdb , in this 
order.
They're called:
build-gcc
build-binutils
build-newlib
build-gdb

I made also a folder h8300-elf-gnu to install there.

Sources are contained in miguel/gnu

I made
cd build-newlib
../gnu/binutils/configure --prefix=/h8300-elf-gnu --target=h8300-elf

There's no error message with this , but then I do 

make all

and comes:

miguel@stefan:~/build-binutils > make all
make  all-recursive

What I'm doing wrong?? Why don't I have these headers? should I get other 
fonts?

Thank you!

Same problem.  Try

 ../gnu/configure --prefix=/h8300-elf-gnu --target=h8300-elf

this wouldn't configure not only binutils but the whole gnu? I've made that , 
and seems like the configuration for all the stuff... 
Or , should I do this instead of one configure than one make for binutils , 
that for gcc... Is this the way to configure and Install gnu in one step?

Thanks!!

Yes, you configure everything at once.  Then you can just say "make".

I've just made that , but:
I didn't get an executable looking like h8300-elf-gdb
I ran gdb, but I still have no success with "target sim" command , even though 
this processor should have a built-in simulator.

Thanks again!

That cross-gcc FAQ is dated 1999-12-03!  It's the latest cross-gcc FAQ
that I've ever found.  I don't think anyone is actively maintaining it.

Re: error building gcc , (simulators and targets...)

[msarasa]

Thank you very much for all your support.
As I've said , I'm just a begginner that's why I've probably made a stupid 
error ;-)
Now I finish my day, but as soon as I can I'll tell you more about where 
exactly I've got that FAQ.
Thanks again!
P.S.
What about doc's telling exactly how could I configure, build ... step by step 
, gnu for a specific simulator?? (That could save my ass!! :-D )

I've a feeling that, for this specific case, it isn't GDB's doco, but 
someone elses :-(

Forwarded by request.  Hmm, sounds like the CrossGCC FAQ....

I follow the instructions given in a FAQ that says
"How to configure , build and install GCC as a Cross-compiler"
Right now , I must search where exactly is that, because I've a true mess with 
all the FAQs Howtos and docs, sorry.

What I tried to do is to configure gcc to use with a simulator. 
First I tried to build Binutils, GCC, Newlib and Gdb in a separate path. 
In this FAQ it's said that I must build these four things in four different 
folders, and in the order I've said. 

Any ideas? Gnu docs don't help me too much...

Thank You!!!
Miguel

I agree with Andrew C, I think our doco needs an upgrade.  I volunteer
to write a doco patch.  Of course, whether it's good or not is up to

Re: error building gcc , (simulators and targets...)

[Michael Elizabeth Chastain]

Hi Miguel,

What is the configuration command that you used to configure gdb?

Make sure that it is something like this:

  bash% /berman/migchain/source/gdb-5.3/configure --target=m68k-elf

And not this:

  bash% /berman/migchain/source/gdb-5.3/gdb/configure --target=m68k-elf
                                ^^^^^^^^^^^

If there are two 'gdb' names in your configure command, then you are
configuring only the 'gdb' subdirectory, and not the whole 'gdb-5.3'
package.  This results in a problem like the problem you are seeing.

My bet is, just guessing.  Should we make configure check for a
Makefile in the directory above?

Yep.

Too many posts like this are showing up :-(  This suggests a doco 
problem somewhere?

Miguel,  which documentation were you following when doing this?

I think you ran the wrong configure script.  You need to run the one in
the top level, not the one under gdb/ or binutils/.

error building gcc , (simulators and targets...)

[msarasa]

I'm trying to build gcc for a specific target : m68k for example
as I do:
make all
I get this error message:

What should I do? I'm really a begginer!
The goal of my efforts is to configure gdb to its use with a simulator, in 
order to see what should I do to configure my own undefined simulator for a 
new , not defined processor.
Any ideas would be really wellcomed
What could I read? Or analyze?
Thank you very much.
Miguel
