Hi,

I am getting following linker errors using g++

***`__static_initialization_and_destruction_0'
***iostream:76: undefined reference to `std::ios_base::Init::Init()'
***iostream:76: undefined reference to `std::ios_base::Init::~Init()'

GNU/Linux using g++

.\Objects\main.o: In function 
`__static_initialization_and_destruction_0':

/cygdrive/c/Hitex/GnuToolPackageArm/bin/../lib/gcc/arm-hitex-elf/4.1.1/. 
./../../../include/c++/4.1.1/iostream:76:  undefined reference to 
`std::ios_base::Init::Init()'

/cygdrive/c/Hitex/GnuToolPackageArm/bin/../lib/gcc/arm-hitex-elf/4.1.1/. 
./../../../include/c++/4.1.1/iostream:76:  undefined reference to 
`std::ios_base::Init::~Init()'

It is a very simple C++ code which is not using any special C++ 
features.
The code compiles,links and runs fine when <iostream> is "NOT" included 
in the main.cpp file.

but as soon as <iostream> is included in the main.cpp file, the code 
compiles, but the above linker error is generated.

Any help is appreciated!!!
Thanks!

You are not linking against the C++ runtime (libstdc++), which would 
provide you with your missing symbols.

It is recommended to use g++ itself (arm-hitex-elf-g++ in your case) for 
linking. This ensures that all necessary runtime libraries are included 
automatically. If you want to provide parameters to the linker itself 
(like -nostartfiles or -Map in your case), you can do this using the 
"-Wl,..." parameter to g++, for example "-Wl,-nostartfiles".
