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
