libg++?

libg++?

[Chip Salzenberg]

Could someone please explain the relationships among libio, libstd++, and
libg++?  And given all the activity in C++, could someone explain why
libg++ hasn't been modified since 14 February 1997 (version 2.8.0b6)?

egcs v970828 builds fine on linux-i586libc1 =)

[Derek Wildstar]

Built the whole dist with CFLAGS='-O6 -mpentium -pipe' CXXFLAGS='-O6 -mpentium
-pipe' LDFLAGS='-m486 -s -Xlinker -n'....the whole package built fine.  I then
went into the gcc dir and built stage1, stage2, stage3 in the normal fashion
to test the compiler.  Everything appears to be working, even with '-O6
-mpentium'.  

On a side note, it may be worth mentioning that XFree86 should _not_ be built
with -O6.  The package builds, but some strange runtime problems pop up...the
most annoying of which is a keyboard mapping problem that causes certain keys
to send characters when they are released instead of when they are pressed.
After rebuilding the package with -O2 the problems went away.  (not saying
this is a compiler problem, just for your reference if you end up building X
;)

The last thing...honest...I was just wondering how up-to-date the
pentium-specific stuff is in egcs (ie if i have 970828, is this reasonably
close to 970821+the pcgg patch)  Since i'm in a pretty good position to
break^H^H^H^H^Htest this stuff on my own system, i'd like to stay as current
as possible.  Going to attempt a couple egcs cross-compiler builds when I get
the time, i'll let you know how things go (ix86-linux->sparc-sunos4.1.4 and
ix86-linux->sparc-linux), and send fixes if i run into any trouble.

keep up the good work =)

We normally pass on basic problems with libf2c exposed by g77 use to
the excellent f2c maintainer so I've done that for comment.  (I don't
think the g77 frontend has any knowledge of such things; burley
probably can't currently read this due to the GNU notwork.)

But it is a very good test bed for egcs. IMHO, anyone who works
on egcs should get the libg++ addon, just for sanity check.

In case you didn't know... libg++ is considered obsolete
(well, *I* consider it obsolete).  Anyway, it's not being
maintained.

If you are talking about the official libg++-2.8.1.1a, it doesn't
matter when you put the stuff into your source tree. Simply rerun
"make all" will correctly configure the new subdirectory and the build 
it.

I guess the same is true with H.J.'s libg++ addons.

You drop librx and libg++ directories in the tope level egcs source
directory along with gcc. Then you build egcs as usual.

If I want to install libg++ with egcs, do I have to put it in before
compiling egcs, or can it be added afterward?

Thanks..

Hi,

can someone point out where is 
separate libg++ for egcs?

IMO, it's perfect Q&A for FAQ and
probably we should keep it (i.e. libg++)
in infrastructure dir.

just a thought...

regards

OK

I use a slightly modified version of libg++-2.8.0b6. The only mods are:
    
    - patch from HJ Lu to fix a bug (shows up only with glibc2? Can't
      remember exactly)
    - replace gxx_includedir with gxx_include_dir to conform to the new
      egcs configure (as of egcs-971127 I believe).

Is anyone working on reconstructing libg++ so that it will work with
egcs?  I realize that it is somewhat officially considered *obsolete*
but we have a bunch of legacy code that, until we get it converted,
depends critically on libg++.

The only parts of old libg++ that I think are that interesting anymore are
the random number classes: there's a nice scheme to generate a variety of
types of random numbers with different distributions.  I think these
originally came from Dirk Grunwald's Awesime project, not from Doug Lea.
Ptolemy used them.

Much of the rest of libg++ I would consider obsolete: String, Complex,
the containers, especially now that we have the SGI hashing classes and
singly linked list.  Just the same, some people still use it, so we can
put it out and call it deprecated.

libio is Per's iostream code (and stdio, but most targets don't use that).
libstdc++ is the rest of the standard library.
libg++ is Doug Lea's old C++ class library.

The libg++ directory hasn't been modified because it doesn't relate to the
standard, and we're not interested in maintaining it anymore (I think;
right, Ulrich?).  Someone else is welcome to take it over.
