Hello,
I have built GCC 4.6.0 on Solaris10/SPARC using following
configuration to make the compiled GCC use GNU ld and as.
The GNU ld and as are from GNU binutils downloaded from SUN free
software. ld version is 2.21
The GCC and related libraries (GMP, MPFR, MPC) are installed in
/lab/home/zuoqi/gcc32/gcc-gnu-ccs
#!/bin/sh
LD_LIBRARY_PATH=/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib
export LD_LIBRARY_PATH
cd /lab/home/zuoqi/gcc32/build-gcc-gnu-ccs
rm -rf *
../gcc-4.6.0/configure ABI=32
--prefix=/lab/home/zuoqi/gcc32/gcc-gnu-ccs --with-gnu-as
--with-as=/usr/local/bin/as --with-gnu-ld --with-ld=/usr/local/bin/ld

--without-cloog --enable-plugin --enable-lto
make -j 64
make check
make install
echo gcc DONE!
After the buiding was done, I set the LD_LIBRARY_PATH to
/lab/home/zuoqi/gcc32/gcc-gnu-ccs/lib.
There's no problem to compile c programs. However, when I tried to
compile c++ programs with std headers, there were errors related to
undefined reference.
The program is hello.cpp as follow:
#include<iostream>
using namespace std;
int main()
{
cout << "hello" <<endl;
return 1;
}
The compile command is : /lab/home/zuoqi/gcc32/gcc-gnu-ccs/bin/g++ hello.cpp
The errors are:
/var/tmp//ccckp3Mi.o: In function `main':
hello.cpp:(.text+0x20): undefined reference to `std::cout'
hello.cpp:(.text+0x24): undefined reference to `std::cout'
hello.cpp:(.text+0x48): undefined reference to
`std::basic_ostream<char, std::char_traits<char>
>::operator<<(std::basic_ostream<char, std::char_traits<char> >&
(*)(std::basic_ostream<char, std::char_traits<char> >&))'
collect2: ld returned 1 exit status
BTW, if I use the default AS and LD path setting for GCC building,
which is /usr/ccs/bin, the as will give following errors. I searched
on the web that the GCC will use the hard-built-in ld first, if there
is any. Then the GCC will use /usr/ccs/bin/as and /usr/ccs/bin/ld even
if the AS and LD enviroment variables are set. So I tried to use GNU
AS and LD in /usr/local/bin while building GCC4.6.0

Would anyone give me some hints about this problem? Thanks a lot!
