Hi,

I found the problem. HP linker default linkinge ist
dynamic and it try to link main.o with libstdc++.sl.
However the installed shared version of libstdc++ 
does not go with the installed gcc version. 
(latest installed gcc was configured with "--disable-shared")
After forcing a static linking (with -aarchive,-lstdc++)
all was fine.

Thomas

Hi,

I did now a : 
1) g++ -c main.cpp
2) g++ -W,l -v main.o

to get more linker output and I see:

gcc was built with "--disable-shared" so the linker does not try link against the shared
libraries, but how can I verify that stdc++ library used is the wrong one ?

BTW, on another HPUX a gcc3.2 is running built without the "--disable-shared" option
and the program build fine.

I did further a:

nm main.o | grep stringstream 
and got
U _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEEC1ESt13_Ios_Openmode
U _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEED1Ev

Now I did a:

my_host(my_user):/usr/local/lib> nm libstdc++.a | grep _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEED1Ev    
00000000 T _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEED1Ev

my_host(my_user):/usr/local/lib> nm libstdc++.a | grep _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEEC1ESt13>
00000000 T _ZNSt18basic_stringstreamIcSt11char_traitsIcESaIcEEC1ESt13_Ios_Openmode

The symbols are found. What do I misunderstand ?

On another HPUX with gcc 3.2 the small progam
compiles/run fine.
So I think it is a installation problem. How can I 
verify what is the broken component ?
