Detailed instructions for installing ASN.1 Development Tools and Plugins

If you are new to Eclipse, follow these useful detailed installation instructions. They describe how to install the ASN.1 Development Tools and optionally the ASN.1 compilers and other tools.

Installing the ASN.1 Development Tools from a local update archive

As an alternative to installing from the update site, you can also install the ASN.1 Development Tools by downloading the update site as an archive and installing from it. You may find this alternate approach helpful when Eclipse can't reach the update site, which is the case behind some firewalls (if you know the proxy information, try configuring Eclipse to use the proxy first, see the instructions).

  1. Download the latest update site archives:
    Local update archive Version Size MD5 Checksum
    ASN.1 SDK (plugins included)
    ASN.1 C Compiler
    ASN.1 C++ Compiler
    ASN.1 Java Compiler
  2. Unzip the archive.
  3. In Eclipse, choose Help > Install New Software...
  4. In the "Work with" section, click the Add... button. The "Add Repository" dialog box appears.
  5. Click Local and select the directory you unzipped, then click OK. Its path appears in the "Location" field. Leave the "Name" field empty.
  6. Continue with step 2 of the installation instructions, as summarized here:
    1. Select the software components you want.
    2. Click Next to review the list of items to be installed, click Next again to read and accept the license agreements, then click Finish. Eclipse will then install any external dependencies, and add the chosen components to the Eclipse installation.
    3. When asked, restart Eclipse.

The plugin should now be installed!

Download the ASN.1 Compiler Command Line

  1. Download the ASN.1 Compiler Command Line jar:
    Runnable jar archive Version Size MD5 Checksum
    ASN.1 Compiler CLI (C/Java only)
  2. Command format for invoke the ASN.1 Compiler in command line:
    java -jar asncl.jar options
    where options are:
     -lang       compile to the given target language, c/java
     -source         use given source folder
     -output         use given output folder
     -prefs          use given preference file
     -D    use value for given property
     -verbose              be extra verbose
  3. Or invoke the ASN.1 Compiler from ant script like:
    <target name="compile">
    	<taskdef name="asncl" classpath="asncl.jar" 
    			classname="org.asnlab.asndt.core.ant.AsnCompilerTask" />
    	<asncl language="java" verbose="false"
    			sourceFolder="source" 
    			outputFolder="output"
    			prefsFile="org.asnlab.asndt.core.prefs"/>
    </target>
    The preference file 'org.asnlab.asndt.core.prefs' can be obtained by right click on an ASN.1 project and select 'Properties' from the popup menu, In the populated project properties page, select ASN.1 > [ASN.1 Compiler], and check the 'Enable project specific settings' option. This will force eclipse generate a preference setting file named 'org.asnlab.asndt.core.prefs' under the .setting folder. (If you can't see this folder, please configure filter to show .* resources)
