g++ 3.0.1 and ARM-ELF

[João Cadamuro Junior]

Hello,

I'm trying to compile a simple program with g++ for arm.

My platform is:

host=win2k, SP2, with cygwin-1.3.2
target=arm-elf
gcc_version=3.0.1
library=newlib-1.9.0

The program is:
--------------------------------------------
class complex {
 private:
  int real;
  int imag;
 public:
//  complex() { real = 0; imag=0; }
};

int main (void)
{
    complex a;
    return 0;
}
--------------------------------------------

Te command line is:

arm-elf-g++ -gdwarf-23 -mcpu=arm7tdmi -mlittle-endian -mapcs-32 -v -o
my_first.elf  my_first.cpp

With the class constructor commented, the program compile and link
without problems. But when I add the class constructor in the code, I
get some strange errors, like...

/armtools/lib/gcc-lib/arm-elf/3.0.1/../../../../arm-elf/lib/libstdc++.a(eh_personality.o):
In function `read_encoded_value_with_base':
/src/gcc/gcc-3.0.1/gcc/unwind-pe.h:133: undefined reference to `LLSDA8'

/src/gcc/gcc-3.0.1/libstdc++-v3/libsupc++/eh_aux_runtime.cc:42:
undefined reference to `LLSDA2'
collect2: ld returned 1 exit status


Sounds like stdc++ library is broken and is unable to find the object
with the "this" pointer.

Someone has any idea about this problem???


Thanks in advance,
