2 (small?) problems

2 (small?) problems

[Thomas Hiller]

Hello,

I encountered 2 problems with the current snapshot (beside some others already 
mentioned on the list).

1)	c++filt is not installed.

2)	Shared libg++ problem.
	I have a problem (also with the normal gcc), when I install the compiler
	in a non-standard place (e.g. /work/egcs). The shared libg++ is not
	found. I had to set the LD_LIBRARY_PATH to include $prefix/lib. Is there
	a portable way to set the shared library path from the compiler ? The
	compiler already issues -L$prefix/lib.
	
Greetings
	Thomas

I'd be happy to provide a patch to make it disappear. Do you want one?

I would be happy to do at least some of this work of sifting through
the RCS files. Are they available somewhere?

Will egcs support MachTen?

[N8TM]

I have been following g77 alpha successfully on MachTen 4.03.  In view of the
interest in merging g77 alpha and egcs work, I'd like to know if egcs can be
made to work on MachTen.  I spent a few hours at it yesterday without
success.

This is somewhat in violation of the ANSI C rules about names. I have a patched version
of gcc 2.7.1 (vax vms) that translates ANSI C names (to those found in the DEC
runtime libraries) in the assembler, this is much like that done by DEC's DECC compiler.

I still have to fix the passing of some attributes via the name prefixing hack used by
gcc vax/vms.

It's about right for daxpy on my pentium.

Hello,

        I have been reading the list and looking at the snapshot over the
weekend, and it seem's clear that I'm a bit lost. Can some one point to me some
reading to do in the hope that I can contribute one day something usefull?

        Utill that day I'll keep reading and trying to play with the snapshot.
Thank's for being their.

What kind of problems did you run into?  If you don't describe them with
enough detail, then we can't help you.
