[ECOS] gnupro toolkit?

[ECOS] gnupro toolkit?

[Tom Marshall]

I am trying to setup eCos for an x86 target.  I have successfully built the
eCos host tools from CVS and installed them, configured the "pc" target, and
here's what I get when I run make:

i386-elf-gcc [...] /usr/local/ecos/packages/services/memalloc/common/current/src/heapgen.cpp -o heapgeninc.tcl
make[1]: i386-elf-gcc: Command not found
make[1]: *** [heapgeninc.tcl] Error 127

I assume that I need the GNUPro tools for compiling stuff on the target
machine but I can't find them anywhere.

you mean cross compiling to the target machine, right?

Yes .. I assume my normal Linux "gcc" won't work because it's going to build
binaries for Linux/glibc.  If I was compiling for another CPU such as ARM or
SuperH, I would certainly need a cross-compiler for it.  I assume the same
will probably apply for the "pc" target .. if nothing else, for the
different crt0 code, linking and such.

[michael shiloh]

right, just wanted to make sure we're on the same
page.

there are indeed cross versions of all the hostside
tools. i'll hunt through my notes to see how and 
where i got them. 

have you searched the ecos website and the mailing
list archives? i'm pretty sure this is discussed in
one or the other.

you might also look through all the 'latest' ecos
documentation, as they call it: 

  http://sources.redhat.com/ecos/docs-latest/

i seem to recall that in all this body of knowledge
there were conflicting instructions for getting 
and building the cross tools, which is why i want
to search my notes. 

good luck,

michael

ok, here's what i think i did. this is untested from
notes i took when i installed, hopefully any mistakes
will be pretty obvious. note that you need both c and 
c++.

good luck:


get:

    ftp://ftp.gnu.org/gnu/binutils/binutils-2.11.2.tar.gz
    ftp://ftp.keystealth.org/pub/gnu/gcc/gcc-3.0.3/gcc-core-3.0.3.tar.gz
    ftp://ftp.keystealth.org/pub/gnu/gcc/gcc-3.0.3/gcc-g++-3.0.3.tar.gz
    ftp://ftp.keystealth.org/pub/gnu/gdb/gdb-5.1.1.tar.gz

  into /wherever/gcc

untar source:

  mkdir -p /src/binutils /src/gcc /src/gdb

  cd /src/binutils
  tar -zxvf /wherever/gcc/binutils-2.11.2.tar.gz

  cd /src/gcc
  tar -zxvf /wherever/gcc/gcc-3.0.3.tar.gz
  tar -zxvf /wherever/gcc/gcc-core-3.0.3.tar.gz
  tar -zxvf /wherever/gcc/gcc-g++-3.0.3.tar.gz

  cd /src/gdb
  tar -zxvf /wherever/gcc//gdb-5.1.1.tar.gz


1.Configure the GNU Binary Utilities:
  
  mkdir -p /tmp/build/binutils
  cd /tmp/build/binutils
  /bin/rm -rf /tmp/build/binutils/*
  /src/binutils/binutils-2.11.2/configure --target=i386-elf \
  --prefix=/tools \
  --exec-prefix=/tools/H-i686-pc-linux-gnu \
  -v |& tee configure.out 

2.Build and install the GNU Binary Utilities:

  make -w all |& tee make.out 
  make -w install 

3.Configure GCC, ensuring that the GNU Binary Utilities are
at the head of the PATH:

  set path = ( /tools/H-i686-pc-linux-gnu/bin $path )
  mkdir -p /tmp/build/gcc
  /bin/rm -rf /tmp/build/gcc/*
  cd /tmp/build/gcc 
  /src/gcc/gcc-3.0.3/configure --target=i386-elf \
  --prefix=/tools \
  --exec-prefix=/tools/H-i686-pc-linux-gnu \
  --with-gnu-as --with-gnu-ld --with-newlib \
  -v |& tee configure.out

4.Build and install the GNU Binary Utilities:

  make -w all-gcc LANGUAGES="c c++" |& tee make.out
  make -w install-gcc LANGUAGES="c c++" |& tee make.out

Okay so you got the GNU tools directly, not some "GNUPro" thing?  That helps
a lot.  I'll give it a try, thanks.

Actually that does tend to work if you have a Linux host (not Cygwin). Set
CYGBLD_GLOBAL_PREFIX to "" in your eCos configuration and it will use the
native tools. eCos overrides the crt0, linker script etc. We've certainly
had it working like this before.

[ECOS] GNUPro Toolkit ?

[Mont Pierce]

Is the unsupported GNUPro Toolkit still free?

Where can I download it from?

I'm using Win98/ME to develop applications for PowerPC MPC860SAR.


Thanks,
Mont
