Hello!   We just installed the gcc-2.2.2 and libg++-2.1.  I have a program which
were successfully compiled and linked under Sun C++ 2.0.  gcc-2.2.2 compiled this
code but not linked successfully. (We are not using GNU ld, I think).

Two things happened at the linkage time:

1. I have the following error message.
$ g++ -g -O -L../test -o prog prog.o -Bstatic -ltest -lg++ -lm  
ld: -ltest: expected libx.so(.major.minor.xxx)

collect: /usr/bin/ld returned 4 exit status
/usr/local/bin/gcc: file path prefix `static' never used


2. If I explicitly specify my own library libtest.a as:
$ g++ -g -O -o prog prog.o -Bstatic ../test/libtest.a -lg++ -lm
ld: Undefined symbol 
   _setprecision 
collect: /usr/bin/ld returned 1 exit status
/usr/local/bin/gcc: file path prefix `static' never used

This looks like libg++-2.1 still does not have the setprecision member function
for ostream.

I would appreciate your help in these two problems.

setprecison is not a member function, it is an io manipulator.
libg++-2.1 *does* have ios::precision(int) which can be used instead.

libg++-2.3 will have setprecision, and a complete template-based
iomanip.h (assuming a suitable fixed g++ is released before then).
