  50                            <div class="entry-body">
  51                               <p>I experienced the following issues when attempting to build LOS178 with the 3.4.3 toolchain:</p>
  52
  53 <h3>Need to have xcoff cdk</h3>
  54
  55 <p>In order to perform the build the xcoff version of the cdk needs to be untarred. This was obtained from 2.0.0 (98r2) tarball:</p>
  56
  57 <div class="code"><pre>
  58     $ tar -zxpf ../1033-00.cdklinux.tar.gz
  59 </pre></div>
  60
  61 <br>
  62
  63 <h3>Need to get files from ppc.cdksol.tar.gz from sys/miscgcc</h3>
  64
  65 <p>In order to perform the build one needs to extract files from bin-image/ppc.cdksol.tar.gz, specifically the sys/miscgcc area:</p>
  66
  67 <div class="code"><pre>
  68     $ tar -zxpf ../bin-image/ppc.cdksol.tar.gz sys/miscgcc
  69 </pre></div>
  70
  71 <br>
  72
  73 <h3>Need to extract 3.4.3 toolchain</h3>
  74
  75 <p>After successfully building 3.4.3 gcc, package it up and then use it to extract here:</p>
  76
  77 <div class="code"><pre>
  78 $ tar -zxpf ../toolchain/toolchain-i686-pc-linux-gnu-powerpc178.tar.gz
  79 </pre></div>
  80
  81 <br>
  82
  83 <h3>Toolchain's cdk/linux-elf-ppc lacks a bin directory</h3>
  84
  85 <p>Normally under cdk/linux-xcoff-ppc there is both a usr and a bin directory. Some entities are just a symlink back to their counterparts in ../usr/bin (e.g. ld -> ../usr/bin/ld). This bin directory structure is not present after untarring toolchain-i686-pc-linux-gnu-powerpc178.tar.gz. For building purposes the following was done:</p>
  86
  87 <ol>
  88   <li>Create a bin directory in cdk/linux-xcoff.ppc</li>
  89
  90   <li>Create symlinks to ../usr/bin:
  91
  92 <div class="code"><pre>
  93       $ for link in ar as byacc c++ cmp diff diff3 expect flex gcc ld \
  94       > make nm ranlib size strip; do
  95       > ln -s ../usr/bin/$link $link
  96       > done
  97 </pre></div>
  98
  99       Note: Some of these are probably not necessary</li>
 100
 101   <li>Copy the following files from linux-xcoff-ppc/bin -> linux-elf-ppc/bin:
 102
 103 <div class="code"><pre>
 104       $ for file in bison bison.hairy bison.simple coffcorrupt cofflook \
 105       > config crc elflook gnutar gunzip gzcat gzexe gzip install mkbootprep \
 106       > mkimage mktimestamp prepend-crc vctchk yacc zcmp zdiff zforce zgrep \
 107       > zmore znew; do
 108       > cp ../../linux-xcoff-ppc/bin/$file $file
 109       > done
 110 </pre></div>
 111
 112       Note: Some of these are probably not necessary</li>
 113 </ol>
 114
 115 <h3>libgcc.a not present</h3>
 116
 117 <p>The build failed because it was unable to find libgcc.a. The solution was to copy libgcc.a into the right place:</p>
 118
 119 <div class="code"><pre>
 120     $ mkdir lib
 121     $ cp cdk/linux-elf-ppc/usr/lib/gcc/powerpc-lynx-lynxos178/3.4.3/libgcc.a lib
