Hello!

The undefined variable LINUX_DYNAMIC_LINKER, included in the Variable LINK_SPEC
in the file gcc-4.2.1/gcc/config/arm/linux-elf.h lines 56-68 causes an error
during compilation of gcc-4.2.1/gcc/gcc.c at line 740. The error was:

path/gcc-4.2.1/gcc/gcc.c:740: error: expected ‘,’ or ‘;’ before
‘LINUX_DYNAMIC_LINKER’

Defining this variable fixed the compilation problem. 

I assume, a reasonable value would be e.g.

#define GLIBC_DYNAMIC_LINKER "/lib/ld-linux.so.2"
#define LINUX_DYNAMIC_LINKER GLIBC_DYNAMIC_LINKER

and will solve this problem at once. I looked up, how this variable was defined
in other architecture header files e.g. at
gcc-4.2.1/gcc/config/alpha/linux-elf.h. There is the dynamic linker of uClibc
("/lib/ld-uClibc.so.0") used as well. Maybe it is more reasonable to use the
same definition like in the alpha header file.

Also, there is another bug, caused by the undefined funcion or macro 
LINUX_TARGET_OS_CPP_BUILTINS() in the same file
(gcc-4.2.1/gcc/config/alpha/linux-elf.h) line 73, which caused a compilation
error in file gcc-4.2.1/gcc/c-cppbuiltin.c line 559: The error was:

c-cppbuiltin.o: In function `c_cpp_builtins':
path/gcc-4.2.1/gcc/c-cppbuiltin.c:559: undefined reference to
`LINUX_TARGET_OS_CPP_BUILTINS'

Before I posted this bug, I had a look at the current development tree snapshot
  (file gcc-4.3-20070803.tar.bz2) and found the same header file. (with minor
change in commentaries)

The configuration was:

configure --prefix=/prefix --build=i686-pc-linuc-gnu --host=i686-pc-linuc-gnu
--target=arm-none-uclinux --disable-nls --disable-shared --enable-languages=c
--disable-threads --disable-tls --with-sysroot=/prefix/sysroot --with-gnu-as
--with-gnu-ld --without-headers

Best regards

LINUX_DYNAMIC_LINKER et al are defined in gcc/config/linux.h and the correct
definition must reach this case. Looking at the config parameters for --host
and --build , I can spot a typo of linuc-gnu instead of linux-gnu. That might
be one reason why the build isn't working for you . 

arm-linux-gnueabi is a standard build and I bootstrap it regularly and many
folks use crosstool to build such a cross configuration. You might consider
using this for your purposes. 

Can you check with a 4.3 toolchain or a compiler of recent vintage with the
correct parameters to --build , --host . Please also indicate the host platform
on which you were trying this.

Does this mean the target "arm-none-uclinux" is unsupported?

I checked again, using (binutils-2.17 and) gcc-4.3.3 from mirror site
ftp://ftp.gwdg.de/pub/misc/gcc/releases/gcc-4.3.3/gcc-4.3.3.tar.bz2

Configuration was:

./configure --prefix=/prefix --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu
--target=arm-none-uclinux --disable-nls --disable-shared --enable-languages=c
--disable-threads --disable-tls --with-sysroot=/prefix/sysroot --with-gnu-as
--with-gnu-ld --without-headers

I can confirm, that fixing my typo resolved the above issues. But I get several
other errors. I guess this is a different issue?!

that must be a different issue . I'd suggest you file a fresh bug entry for
that as well as consider using the new ABI with arm-uclinux-eabi if you need
to.

Thanks.
