HELP - GCC Cross Compiler: LD Returns "`_atexit` undefined in fuction `__do_global_ctors'"

[Dominic Clifton]

Hi there..

I'm tying to get a cross-compiler working so that I can code C programs for
a Sega Dreamcast (Hitachi SH4).

I downloaded:

binutils-2.10.tar.gz
gcc-core-2.95.2.tar.gz

uncompressed them to /usr/src/crosscompiler and then did the following
commands:

$ target=sh-elf
$ prefix=/usr/local/crosscompiler
$ i=$prefix/bin
$ PATH=$i:$PATH


$ mkdir build-binutils
$ mkdir build-gcc

$ cd build-binutils
$ ../binutils-2.10/configure --target=$target --prefix=$prefix
$ make all install

$ cd ../build-gcc
$
../gcc-2.95.2/configure --target=$target --prefix=$prefix --without-headers
--without-libs --with-cpu=sh4

Then "vi /gcc/Makefile" and adding "-Dinhibit_libc" to
"TARGET_LIBGCC2_CFLAGS="

$ make LANGUAGES="c" all install

Then I add my new /bin directory with my new binaries to the path

$ PATH=$i:$PATH

Then I'm creating a "test.c" file:

void main ( void) {
}

Then I compile like this:

sh-elf-gcc -ml -Wl,-Ttext,0x8c010000 -nostartfiles -nostdlib -e _main
test.c -o test.elf -lgcc

and it returns:

test.c: In function `main':
test.c:1: warning: return type of `main' is not `int'
/usr/local/crosscompiler/lib/gcc-lib/sh-elf/2.95.2/ml/libgcc.a(__main.o): In
fuction `__do_global_ctors':
__main.o(.text+0x74): undefined reference to `atexit'
collect2: ld returned 1 exit status

How do I fix this ?

I'm guessing I need some form of linker script, but can someone tell me what
I need please ?

I've been trying to get this to work for a week now, it's driving me mad!

Dom

p.s.  I downloaded "newlib-1.8.2.tar.gz" and "make"'d that, but the same
thing
happens. (Which I'd of expected anyway..)
