HelloWorld Problems

["X X" <x1x82 at hotmail dot com>]

Hello Community,

I am having problems compiling a simple HelloWorld program using GNU GCC. I
can't seem to use the -G, -symbolic, or -shared switches (which I don't
really need for my simple program, but do need for something a bit more
robust)...

The Specs...

OS: Solaris7
COMPILER: GNU gcc 2.95.3 (from sunfreeware.com)
LINKER: GNU ld 2.11.2 (with BFD 2.11.2) (from sunfreeware.com)

LD_LIBRARY_PATH=/usr/local/lib

The Program...

#include <iostream.h>

int main(int argc, char** argv)
{
cout << "HELLO WORLD!" << endl;
return 0;
}

The compiles (and the results)...

FIRST COMPILE

[/]$g++ -c -o HelloWorld.o HelloWorld.cpp

The above is successful and produces HelloWorld object file

[/]$g++ -o HelloWorld HelloWorld.o

The above is successful and produces HelloWord executable file

[/]$HelloWorld
HELLO WORLD!

The above is successful and outputs HELLO WORLD! on the console.

[/]$ldd HelloWorld
libstdc++.so.2.10.0 => /usr/local/lib/libstdc++.so.2.10.0
libm.so.1 => /usr/lib/libm.so.1
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1

SECOND COMPILE

[/]$g++ -c -o HelloWorld.o HelloWorld.cpp

The above is successful and produces HelloWorld object file

[/]$g++ -G -o HelloWorld HelloWorld.o

The above is successful and produces HelloWord executable file

[/]$HelloWorld

The above is NOT successful. It just hangs...

[/]$truss -f HelloWorld
18643:  execve("HelloWorld", 0xFFBEF83C, 0xFFBEF844)  argc = 1

and it just hangs.

[/]$ldd HelloWorld
libstdc++.so.2.10.0 => /usr/local/lib/libstdc++.so.2.10.0
libm.so.1 => /usr/lib/libm.so.1
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1

THIRD COMPILE

[/]$g++ -c -o HelloWorld.o HelloWorld.cpp

The above is successful and produces HelloWorld object file

[/]$g++ -shared -o HelloWorld HelloWorld.o

The above is successful and produces HelloWorld executable file

[/]$HelloWorld
Segmentation Fault(coredump)

The above is NOT successful. It immediately core dumps with a segmentation
fault...

[/]$truss -f HelloWorld
18659:execve("HelloWorld", 0xFFBEF83C, 0xFFBEF844)  argc = 1
18659:  Incurred fault #6, FLTBOUNDS  %pc = 0x00000008
18659:    siginfo: SIGSEGV SEGV_MAPERR addr=0x00000008
18659:  Received signal #11, SIGSEGV [default]
18659:    siginfo: SIGSEGV SEGV_MAPERR addr=0x00000008
18659:      *** process killed ***

[/]$ldd HelloWorld
libstdc++.so.2.10.0 => /usr/local/lib/libstdc++.so.2.10.0
libm.so.1 => /usr/lib/libm.so.1
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1

FOURTH COMPILE

[/]$g++ -c -o HelloWorld.o HelloWorld.cpp

The above is successful and produces HelloWorld object file

[/]$g++ -symbolic -o HelloWorld HelloWorld.o

The above is successful and produces HelloWorld executable file

[/]$HelloWorld
Segmentation Fault(coredump)

The above is NOT successful. It immediately core dumps with a segmentation
fault...

[/]$truss -f HelloWorld
18659:execve("HelloWorld", 0xFFBEF83C, 0xFFBEF844)  argc = 1
18659:  Incurred fault #6, FLTBOUNDS  %pc = 0x00000008
18659:    siginfo: SIGSEGV SEGV_MAPERR addr=0x00000008
18659:  Received signal #11, SIGSEGV [default]
18659:    siginfo: SIGSEGV SEGV_MAPERR addr=0x00000008
18659:      *** process killed ***

[/]$ldd HelloWorld
libstdc++.so.2.10.0 => /usr/local/lib/libstdc++.so.2.10.0
libm.so.1 => /usr/lib/libm.so.1
libc.so.1 => /usr/lib/libc.so.1
libdl.so.1 => /usr/lib/libdl.so.1
/usr/platform/SUNW,Ultra-5_10/lib/libc_psr.so.1

Again, I am having trouble using the -G, -shared, or -symbolic switches. I
do admit that I am not a compile person and have limited understanding of
the switches I am using, so hopefully my mistake will be silly.

Thanks Community!
