With gcc2.2.2 using g++ one did not have to tell g++
where libg++ was. Under gcc2.3.1 which I just installed
it appears that g++ wants you to tell it where libg++ is
with a -L. Is this true or did I screw up the install.

I just built gcc the same way I have in the past on a decstation.
Nothing fancy.

From the final link of a trivial C++ program: g++ -v -o foo foo.C

2.2.2
 /usr/local/gnu/lib/gcc-lib/mips-dec-ultrix/2.2.2/ld -EL -o foo /usr/lib/crt0.o -L/usr/local/gnu/lib -L/usr/local/gnu/lib -L/usr/local/gnu/lib/gcc-lib/mips-dec-ultrix/2.2.2 -L/usr/lib/cmplrs/cc -L/usr/lib/cmplrs/cc -L/usr/local/gnu/lib foo.o -lg++ -lgcc -lc -lgcc

(Note the -L statements are correct for my installation)

2.3.1
/usr/local/gnu/lib/gcc-lib/mips-dec-ultrix/2.3.1/ld -EL -o foo /usr/lib/crt0.o /usr/tmp/cca186051.o -lg++ /usr/local/gnu/lib/gcc-lib/mips-dec-ultrix/2.3.1/libgcc.a -lc /usr/local/gnu/lib/gcc-lib/mips-dec-ultrix/2.3.1/libgcc.a
ld:
Can't locate file for: -lg++
collect: /usr/bin/ld returned 1 exit status

(Note the changed system of direct paths to libgcc and no -L/usr/local/gnu/lib)

If I add a -L/usr/local/gnu/lib it all works fine, my question is
how do I get back the older more convenient "autolink" if you will.
Or, do I need to do something special with my install that I didn't
have to do under gcc2.2.2?

  I have found the same problem for an RS/6000, AIX-3.1.6. I patched g++ and c++
as a work around, but from glancing at gcc.c, it looks like something is broken
in the add_prefix() function, used at line 3296.

  The simple (yet brain dead :) fix is to hard code the library in g++ and c++,
like this:

*** ./c++_orig	Thu Nov  5 07:02:18 1992
--- ./c++	Thu Nov  5 07:02:45 1992
***************
*** 25,29 ****
  quote=
  # $library is made empty to disable use of libg++.
! library=-lg++
  numargs=$#
  
--- 25,29 ----
  quote=
  # $library is made empty to disable use of libg++.
! library="-L/stor/gnu/aix/lib -lg++"
  numargs=$#
  

    Cheers,
