C++ program

Xiaowen Wu_1 — Tue, 26 Jul 2005 19:38:01 GMT

I used g++ (version 3.1) to compile a simple helloworld.cpp program. I used -static for the link flags.

#include
#include

int main(int argc, char *argv[])
{
std::string str1 = "hello world";
printf("Hello World \n");
std::cout << "Hello World" << std::endl;
std::cout << str1 << std::endl;
return(0);
}

The program works fine on the machine which have gcc installed, but when I copied the program to another HP-UX machine, which don't have g++ installed, it got a memory falut

# ./he
Hello World
Memory fault(coredump)

and ldd show not missing dynmaic lib.
# ldd he
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2

Does anybody know how to resolve this problem ?

Thank you very much

These are some system libraries.

Check in your new system whether you have those files in /usr/lib.

It also looks like library incompatibility problem.
You might be having a different version of libs in your new machine, something like
libc.1

Both machine have the same version of OS, and seems to both have libc.2 and libdld.2

Which system library need to be verified ?
