Host/Target specific installation notes for egcs-1.0.1
No specific installation needs/instructions.
You will need binutils- or newer for exception handling to
The SCO assembler is currently required. The GNU assembler is not up
to the task of switching between ELF and COFF at runtime.
Unlike various prereleases of GCC, that used '-belf' and defaulted to
COFF, you must now use the '-melf' and '-mcoff' flags to toggle
between the two object file formats. ELF is now the default.
Look in gcc/config/i386/sco5.h (search for "messy") for additional
OpenServer-specific flags.
You'll need a patch to fix an egcs bug on this platform. [1]x86

We highly recommend using gas/binutils-2.8 on all hppa platforms; you
may encounter a variety of problems when using the HP assembler.
The HP assembler has major problems on this platform. We've tried to
work around the worst of the problems. However, those workarounds may
be causing linker crashes in some circumstances; the workarounds also
probably prevent shared libraries from working. Use the GNU assembler
to avoid these problems.
The configuration scripts for egcs will also trigger a bug in the
hpux9 shell. To avoid this problem set CONFIG_SHELL to /bin/ksh and
SHELL to /bin/ksh in your environment.
For hpux10.20, we highly recommend you pick up the latest sed patch
from HP. HP has two sites which provide patches free of charge.

Retrieve patch PHCO_12862.
The HP assembler on these systems is much better than the hpux9
assembler, but still has some problems. Most notably the assembler
inserts timestamps into each object file it creates, causing the
3-stage comparison test to fail during a "make bootstrap". You should
be able to continue by saying "make all" after getting the failure
from "make bootstrap".
You absolutely must use GNU sed and GNU make on this platform.
If you try to build the integrated C++ & C++ runtime libraries on this
system you will run into trouble with include files. The way to get
around this is to use the following sequence. Note you must have write
permission to prefix for this sequence to work.
cd objdir
make all-texinfo all-bison all-byacc all-binutils all-gas all-ld
cd gcc
make bootstrap
make install-headers-tar
cd ..
make bootstrap3
It is reported that you may need the GNU assembler on this platform.
You must use GAS on these platforms, the native assembler can not
handle the code for exception handling support on this platform.
These systems don't have ranlib, which various components in egcs
need; you should be able to avoid this problem by installing GNU
binutils, which includes a functional ranlib for this system.
You may get the following warning on irix4 platforms, it can be safely
warning: foo.o does not have gp tables for all its sections.
You must not use GAS on irix6 platforms; doing so will only cause
These systems don't have ranlib, which various components in egcs
need; you should be able to avoid this problem by making a dummy
script called ranlib which just exits with zero status and placing it
in your path.
At least one person as reported problems with older versions of
gnu-make on this platform. make-3.76 is reported to work correctly.
You will need [4]binutils- for a working egcs. It is
strongly recommended to recompile binutils with egcs if you initially
built it with gcc-2.7.2.*.
It has been reported that you might need binutils- for this
platform too. [5]binutils-
