Tutorial 4

[Mark Butcher]

Hi all GCC Gurus out there !!

The saga continues... Here's the latest news:
- I am quite convinced that I know what I am doing and have writen a script
especially for my favorite target (the Motorola mcore). I have posted it
seperately (for anyone interested to use or test) so as not to make this
mail too much longer that it already is.
- The script is based on information received from several sources (many
thanks to those who have been giving tips over the previous weeks
(months?))
- The script seems to work fine up to the point where the build of the full
gcc fails to compile *.cc library files
- At the point where it fails, all binutil files for the target are in
/usr/local/bin, including the (simple)gcc for the target
- Newlib has been successfully built and is in /usr/local/mcore
(lib/crt0.o, libc.a etc)

- But something goes wrong in libstdc++ when trying to compile c++ sources
as shown in this extract below

*******************(first part ok to show that things are working as
expected up to the failure)**********************************************

So all seems to be working fine up to this point and I can see no obvious
set up errors (for example libraries or headers not being found).
This leads me to ask a few of questions:
1. Is there some other setting which I have missed (all settings are
visible in mcore build script - in seperate mail) ?
2. Is there really a problem with the source files (I don't really
understand the compilation error at the moment)
3. Is the failing library only needed when compiling c++ programs ?
4. If only the c functionality (not c++) is required, could this library be
simply ignored, or would it be best to compile with only c language option
?

I will try the build process with another target tomorrow (with build times
of 8 hours on the home PC, experimentation is quite slow..)

Any comments from the wise ??

I've seen the 'ldiv_t undeclared' problem more than once before:
http://gcc.gnu.org/ml/gcc/2002-02/msg00644.html
http://gcc.gnu.org/ml/gcc/2002-04/msg00908.html

What I have determined is that if a build failed for some reason,
executing a 'make clean ; make ; make install' for the particular
component doesn't always work since the 'make clean' doesn't remove
the *installed* components, or *all* of the config files, so when the
build occurs, it fails again in the same strange way.

What I have found that works is to: 

1) remove *all* the installed components including binutils, gcc and newlib
2) remove *all* of the object directory structures where the tools were
   built
3) rexecute the script which configures and builds the tools

This is the reason that I pick a directory to hole *everything*
installed by a particularly configured toolchain as well as a seperate
directory to hold all of the object directory structures.  If an error
happens, I just blow away the object directory, the installed
directory, and start over.  Fortunately for me it only takes 15
minutes to build it all over again on Linux.

In your case, you could just change PREFIX and remove
${SRC_ROOT}/BUILD and try again to see if it will complete.

Hope this helps...

No it doesn't.  In fact, my script doesn't work either, using gcc-3.1,
binutils-2.12.1, and newlib-1.10.0, all with the same 'ldiv_t not
declared' while building eh_alloc.cc.  So its not your script...

I'll have to start looking into why my script builds a c++ copmiler
using my modified version of gcc-3.0.4, but failes on gcc-3.1, and
I'll check on whether it works on a stock gcc-3.0.4

Re: Tutorial 4

[Mark Butcher]

Hi Peter

Thanks for your comments. In fact I have got into the habit of trashing
everything before trying a build - yesterday I completely deleted all build
file and the tool directories (like a fresh install) and the error was
identical - this on two differenct computers (using cygwin shell - under
Windows 98 and Window NT).

It looks as though we are more or less in agreement that the build method
is basically correct and like you, being a pure c-programmer (with just a
little c++ experience) it means studying the language some more to
understand the problem.

I would be very interested to know whether the scrips works in a Linux
environment ! It would certainly be interesting if there are some
environment dependencies.

In the meantime I'll get my head down in my "Now I'm going to learn C++
book"...... (just noticed I took it in to the office so it will have to
wait until tomorrow).

Cheers

Mark

PS. I read your posting where you seem to have had an identical problem -
did you not have any response which may aid understanding the root-cause ?
