   9 No specific installation needs/instructions.

  11
  12 <p><b>i?86-*-linux*</b><br>
  13 You will need binutils-2.8.1.0.15 or newer for exception handling to work.
  14
  15 <p><b>i?86-*-sco3.2v5*</b><br>
  16 The SCO assembler is currently required.    The GNU assembler is not up
  17 to the task of switching between ELF and COFF at runtime.
  18
  19 <br>Unlike various prereleases of GCC, that used '-belf' and defaulted to
  20 COFF, you must now use the '-melf' and '-mcoff' flags to toggle between
  21 the two object file formats.     ELF is now the default.
  22
  23 <br>Look in gcc/config/i386/sco5.h (search for "messy") for additional
  24 OpenServer-specific flags.
  25
  26 <br>Systems based on OpenServer before 5.0.4 (<code>uname -X</code> will
  27 tell you what you're running) require TLS597 from ftp.sco.com/TLS for
  28 C++ constructors and destructors to work right.
  29
  30 <p><b>hppa*-hp-hpux*</b><br>
  31 We <b>highly</b> recommend using gas/binutils-2.8 on all hppa platforms; you
  32 may encounter a variety of problems when using the HP assembler.
  33
  34 XXX How to make sure gcc finds/uses gas.
  35
  36 <p><b>hppa*-hp-hpux9</b><br>
  37 The HP assembler has major problems on this platform.  We've tried to work
  38 around the worst of the problems.  However, those workarounds may be causing
  39 linker crashes in some circumstances; the workarounds also probably prevent
  40 shared libraries from working.  Use the GNU assembler to avoid these problems.
  41
  42 <br>The configuration scripts for egcs will also trigger a bug in the hpux9
  43 shell.  To avoid this problem set CONFIG_SHELL to /bin/ksh and SHELL to
  44 /bin/ksh in your environment.
  45
  46 <p><b>hppa*-hp-hpux10</b><br>
  47 For hpux10.20, we <b>highly</b> recommend you pick up the latest sed
  48 patch from HP.  HP has two sites which provide patches free of charge.
  49
  50 <br><a href="http://us-support.external.hp.com">US, Canada, Asia-Pacific, and
  51 Latin-America</a>
  52 <br><a href="http://europe-support.external.hp.com">Europe</a>
  53
  54 <p>Retrieve patch PHCO_12862.
  55
  56 <p>The HP assembler on these systems is much better than the hpux9 assembler,
  57 but still has some problems.  Most notably the assembler inserts timestamps
  58 into each object file it creates, causing the 3-stage comparison test to fail
  59 during a "make bootstrap".  You should be able to continue by saying "make all"
  60 after getting the failure from "make bootstrap".
  61
  62 <p><b>m68k-*-nextstep*</b><br>
  63 You absolutely must use GNU sed and GNU make on this platform.
  64
  65 <p>If you try to build the integrated C++ & C++ runtime libraries on this system
  66 you will run into trouble with include files.  The way to get around this is
  67 to use the following sequence.  Note you must have write permission to
  68 <i>prefix</i> for this sequence to work.
  69
  70 <p>cd <i>objdir</i><br>
  71 make all-texinfo all-bison all-byacc all-binutils all-gas all-ld<br>
  72 cd gcc<br>
  73 make bootstrap<br>
  74 make install-headers-tar<br>
  75 cd ..<br>
  76 make bootstrap3<br>
  77
  78 <p><b>m68k-sun-sunos4.1.1</b><br>
  79 It is reported that you may need the GNU assembler on this platform.
  80
  81 <p><b>mips*-sgi-irix4</b><br>
  82 <b>mips*-sgi-irix5</b><br>
  83 You must use GAS on these platforms, the native assembler can not handle the
  84 code for exception handling support on this platform.
  85
  86 <p>These systems don't have ranlib, which various components in egcs need; you
  87 should be able to avoid this problem by installing GNU binutils, which includes
  88 a functional ranlib for this system.
  89
  90 <p>You may get the following warning on irix4 platforms, it can be safely
  91 ignored.
  92 <pre>
  93     warning: foo.o does not have gp tables for all its sections.
  94 </pre>
  95
  96 <p><b>mips*-sgi-irix6</b><br>
  97 You must not use GAS on irix6 platforms; doing so will only cause problems.
  98
  99 <p>These systems don't have ranlib, which various components in egcs need; you
 100 should be able to avoid this problem by making a dummy script called ranlib
 101 which just exits with zero status and placing it in your path.
 102
 103 <p><b>rs6000-ibm-aix*</b><br>
 104 <b>powerpc-ibm-aix*</b><br>
 105 At least one person as reported problems with older versions of gnu-make on
 106 this platform.  make-3.76 is reported to work correctly.
 107
 108 <p><b>powerpc-*-linux-gnu*</b><br>
 109 You will need
 110 <a href="ftp://ftp.yggdrasil.com/private/hjl">binutils-2.8.1.0.17</a> for
 111 a working egcs. It is strongly recommended to recompile binutils with egcs
 112 if you initially built it with gcc-2.7.2.*.
