egcs-971105 on Openserver 5.04

[jwj at dde dot dk (Jesper Wolf Jespersen)]

I  have  a  few  problems  with egcs on SCO Openserver 5.04 and would
like a bit of advice from the experts.

This  posting  is  a  bit  long,  I  hope  its  not just a waste of
bandwidth :-)

This  is  now  the  third  complete  snapshot  i  have downloaded and
compiled,  with  the  best results yet, but still I cannot complete a
make check from the top directory.

I  havent  been able to find any readme files on how to setup egcs on
my  machine  so I have been doing a bit of guessing along the way. Of
course  I  have  been  following  the discussion in this maillist and
have found some of the conversations quite helpfull.

To  test  my egcs I have built a dejagnu from the 971028 snapshot. It
reports  an  error in the tcl filename-14.1 test, but otherwise shows
no  problem.  It  complains that it cannot find a global config and a
global tool init file. I hope the defaults suffice for testing egcs.

Now  after  building  egcs  i  run  the  make check from the egcs top
directory.  Unfortunately  the  test  stops in libstdc++ and does not
continue to test the rest.
Here is the output of the libstdc++ test:
---

Looking into the log file gives this report for tcomplex.cc:

for tvector.c I get the following result:

A  very  strange  thing  is  that the coff version of this test gives
the follong result:

I  dont  know  how  to  make  the  gcc and g++ tests for both ELF and
COFF, I hope somebody here can tell me how to do those.


One  other  observation  I  made is that the COFF part of libio still
is  being  ELF  compiled.  Sorry  I  dont  know  what  to  do  to the
configure  scripts  to change this, I just put -mcoff in the Makefile
in that directory.


If  it  is  possible to generate a shared version of the ELF librarys
I  would  like  to  know  how.  The  Skunkware  97 version og GCC has
shared libraries, but I dont know how they were made. 
Is this possible ?

I  realy  thing  the  egcs initiative is an improvement its the first
version  of  gcc  that compiles out of the box on SCO Openserver, and
it seems quite a few things have improved over gcc version 2.7.2.

Thanks to all of you.
