Hi All,
I've built the arm-elf tool chain with the following
gcc 3.0.2 release
binutil 2.11.92.0.7
newlib-1.9.0
When I build the following C++ program I get undefined reference to
_gxx_personality_sj0
file t.hpp
| Код |
class foo
{
public:
foo(void);
~foo(void);
void test(void);
}
|
file t.cpp
| Код |
#include "t.hpp"
foo::foo(void)
{;}
foo::~foo(void)
{;}
void foo::test(void)
{;}
|
file tt.cpp
| Код |
#include "t.hpp"
int main(void)
{
foo k;
while(1)
k.test();
}
|
If all the files listed are place in the same source file I don't get the
undefined reference to _gxx_personality_sj0.
Any suggestions?
