How does InstallBuilder know Mac OS X 10.5 (32-bit) vs 10.6 (64-bit) We have a single BitRock installer xml file that needs to support both 32-bit and 64-bit Mac OSX. That is, we need to copy 64-bit library if we install our application on a 64-bit Mac OSX, or 32-bit library, if we install on 32-bit Mac OSX. In both cases, we call platform “osx”. We just pull respective libraries from different origins, either 64-bit subfolder, or 32-bit subfolder on our source platform. Destination folder is the same for both platforms.

How will BitRock know if we need to copy a library from 32-bit source, or from 64-bit source during runtime?

The xml code that does this is as follows:

--32-BIT Part ---

<component> <name>macosx105files</name> <description>Mac OS X 10.5 Files</description> <folderlist> <folder> <description>Mac configuration folder for MacOS 10.5</description> <destination>${installdir}/modules/lib</destination>

                <platforms>osx</platforms>
                <distributionFileList>
                    <distributionFile>
                                               <origin>../MacOSX/OSX_10.5/libusb-1.0.0.dylib </origin>
                    </distributionFile>
    </distributionFileList>
          </folder>
        </folderList>
    </component>

--64-BIT Part --

 <component>
        <name>macosx106files</name>
        <description>Mac OS X 10.6 and Later Files</description>
        <folderList>
            <folder>
                <description>Mac configuration folder - for MacOS 10.6 and later</description>
                   <folderList>
            <folder>
      <description>Mac configuration folder for MacOS 10.6+</description>
    <destination>${installdir}/modules/lib</destination>

                <platforms>osx</platforms>
                <distributionFileList>
                    <distributionFile>
                                               <origin>../MacOSX/OSX_10.6/libusb-1.0.0.dylib </origin>
                    </distributionFile>
    </distributionFileList>
          </folder>
        </folderList>
    </component>

  For detecting version of OSX, you can use <compareVersions> and ${osx_major_version} variable to check the version. For example:

  <compareVersions>
      <logic>greater_or_equal</logic>
      <version1>${osx_major_version}</version1>
      <version2>10.6</version2>
  </compareVersions>
  

  It is also possible to use uname -m command to detect if OSX is running in 32-bit or 64-bit mode. You can first check it at initialization:

  <initializationActionList>
      <setInstallerVariable>
          <name>osx_64bit</name>
          <value>0</value>
      </setInstallerVariable>
      <actionGroup>
          <actionList>
              <runProgram>
                  <program>uname</program>
                  <programArguments>-m</programArguments>
              </runProgram>
              <setInstallerVariable>
                  <name>osx_64bit</name>
                  <value>1</value>
                  <ruleList>
                      <compareText>
                          <logic>contains</logic>
                          <text>${program_stdout}</text>
                          <value>x86_64</value>
                      </compareText>
                  </ruleList>
              </setInstallerVariable>
          </actionList>
          <ruleList>
              <platformTest>
                  <type>osx</type>
              </platformTest>
          </ruleList>
      </actionGroup>
  </initializationActionList>
  

  The ${osx_64bit} variable will now be set to 1 if system is running in 64bit mode. You can then use folder's rules to determine which file(s) will get installed:

  <folder>
      <description>Library 32bit</description>
      <destination>${installdir}</destination>
      <name>library32</name>
      <platforms>osx</platforms>
      <ruleList>
          <isFalse>
              <value>${osx_64bit}</value>
          </isFalse>
      </ruleList>
  </folder>
  <folder>
      <description>Library 64bit</description>
      <destination>${installdir}</destination>
      <name>library64</name>
      <platforms>osx</platforms>
      <ruleList>
          <isTrue>
              <value>${osx_64bit}</value>
          </isTrue>
      </ruleList>
  </folder>
