  84                   <p>I experienced the following issues when attempting to build LOS178 with the 3.4.3 toolchain:</p>
  85
  86 <h3>Need to have xcoff cdk</h3>
  87
  88 <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>
  89
  90 <div class="code"><pre>
  91     $ tar -zxpf ../1033-00.cdklinux.tar.gz
  92 </pre></div>
  93
  94 <br>
  95
  96 <h3>Need to get files from ppc.cdksol.tar.gz from sys/miscgcc</h3>
  97
  98 <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>
  99
 100 <div class="code"><pre>
 101     $ tar -zxpf ../bin-image/ppc.cdksol.tar.gz sys/miscgcc
 102 </pre></div>
 103
 104 <br>
 105
 106 <h3>Need to extract 3.4.3 toolchain</h3>
 107
 108 <p>After successfully building 3.4.3 gcc, package it up and then use it to extract here:</p>
 109
 110 <div class="code"><pre>
 111 $ tar -zxpf ../toolchain/toolchain-i686-pc-linux-gnu-powerpc178.tar.gz
 112 </pre></div>
 113
 114 <br>
 115
 116 <h3>Toolchain's cdk/linux-elf-ppc lacks a bin directory</h3>
 117
 118 <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>
 119
 120 <ol>
 121   <li>Create a bin directory in cdk/linux-xcoff.ppc</li>
 122
 123   <li>Create symlinks to ../usr/bin:
 124
 125 <div class="code"><pre>
 126       $ for link in ar as byacc c++ cmp diff diff3 expect flex gcc ld \
 127       > make nm ranlib size strip; do
 128       > ln -s ../usr/bin/$link $link
 129       > done
 130 </pre></div>
 131
 132       Note: Some of these are probably not necessary</li>
 133
 134   <li>Copy the following files from linux-xcoff-ppc/bin -> linux-elf-ppc/bin:
 135
 136 <div class="code"><pre>
 137       $ for file in bison bison.hairy bison.simple coffcorrupt cofflook \
 138       > config crc elflook gnutar gunzip gzcat gzexe gzip install mkbootprep \
 139       > mkimage mktimestamp prepend-crc vctchk yacc zcmp zdiff zforce zgrep \
 140       > zmore znew; do
 141       > cp ../../linux-xcoff-ppc/bin/$file $file
 142       > done
 143 </pre></div>
 144
 145       Note: Some of these are probably not necessary</li>
 146 </ol>
 147
 148 <h3>libgcc.a not present</h3>
 149
 150 <p>The build failed because it was unable to find libgcc.a. The solution was to copy libgcc.a into the right place:</p>
 151
 152 <div class="code"><pre>
 153     $ mkdir lib
 154     $ cp cdk/linux-elf-ppc/usr/lib/gcc/powerpc-lynx-lynxos178/3.4.3/libgcc.a lib
