problems building a crosscompiler

problems building a crosscompiler

[Michael Wisse]

Hallo !

I try to build a crosscompiler for a LEGO-RCX (with Hitachi H8300
microcontroller).
with help of instructions from legOS.sourceforge.net. 

I use suse linux 6.4 and downloaded binutils2.10.1 and
gcc2.95.2. Configuring and Building of binutils2.10.1 seemed to work
fine on my system with:

 ../binutils-2.10.1/configure --target=h8300-hitachi-hms
--prefix=/usr/local/crossgcc
--exec-prefix=/usr/local/crossgcc/h8300-hitachi-hms   

I couldn't see any errors from the make process.


I configured gcc for hitachi8300 with following:

 ../gcc-2.95.2/configure --target=h8300-hitachi-hms
--prefix=/usr/local/crossgcc
--exec-prefix=/usr/local/crossgcc/h8300-hitachi-hms --with-newlib
--enable-target-optspace 2

" make -i cross LANGUAGES="c c++"  produces many warnings and errors:

./fixinc.sh: cd:
/usr/local/crossgcc/h8300-hitachi-hms/h8300-hitachi-hms/sys-inc
lude: Datei oder Verzeichnis nicht gefunden

Probably the warnings can be ignored, but make doesn't find include
files. First line says, that an include directory can't be found.

Must I edit the Makefile to include a directory? 
Didn't building of binutils worked correct, so that an include directory
is missing?

I don't know. I have no experiences with building a cross compiler and I
would be glad, if someone could give me an advice.

  It happens every now and again.  Most people believe it's a sign of
faulty memory or perhaps a dodgy hard drive read/write messing up your
swap space.  I used to get it quite a lot under cygwin, on two different
PCs, but it doesn't seem to happen so much these days, with newer versions
of the cygwin dll, so I'm not 100% sure that there may not be two different
problems going on.

  In any case, retrying the make usually works; sometimes it will just get
to the same point over and over and fail every time, in which case shutting
down and restarting your computer will usually get it to work next time.
I suspect some kind of race condition or uninitialized memory problem may
also exist but nobody's ever been able to track it down since it usually
disappears the moment you run make under the debugger.  So it isn't worth
worrying about very much.

Hallo Yves!

Yes it helped, thanks.  

I was unsure, if I should build newlib, but it's not necessary.
Additionally I had to add --with-headers to gcc-configuration.
(Perhaps someone has the same problem again.)

Curios was, that I had to make the crosscompiler twice (without "make
clean" in beetween), before the make process finished without errors.
While the first run, there always (I did make and make clean sometimes
to reproduce the error) was an error: 
gcc: Internal compiler error: program cc1 got fatal signal 11
 
Has anyone an idea?


Greetings to Scotland and best regards.

There are linuxes out there that talk german? wow.

I don't know about the warnings.
For the rest, you need to add the header files of the library you
use. 

Assuming you use newlib, go in gcc-2.95.2 and add the links:
ln -s ../newlib-1.8.2/newlib newlib
ln -s ../newlib-1.8.2/libgloss libgloss

Then reconfigure and make should work okay.

Hope I'm right and that helps (heck, I'm new at that too :-)
