  • Using Eclipse

    Hi,
    I checked out: svn checkout http://svnmirror.voltdb.com/eng/trunk/
    and tried to follow the document developer_tools (under trunk/doc) Getting Started in Eclipse


    3. Go to the project's Properties > Java Build Path > Source.
    4. Link the following src dirs:
    - `gpl_src`
    - `hzsqldb_src`
    - `hzsqldb_test_src`
    - `mit_src`
    - `mit_test_src`


    I could not find the mentioned above directories (gpl_src,hzsqldb_src,...).
    Can you tell me where the src dirs are located?


    Thanks,
    Tuan

    That readme is out of date.

    That is an old readme. I apologize for the confusion. We'll clean this up.


    But the good news is creating an eclipse project is easy these days.

    Step 1: In the root directory of your svn checkout, you will find a file, template.classpath. This is a template of a standard eclipse .classpath file. Copy this file to a new file named .classpath. Open the .classpath file in the editor of your choice. Change the first path element of attributes/attribute/@value to match the name of your VoltDB checkout directory. For example, if you typed "svn checkout http://svnmirror.voltdb.com/eng/trunk/ voltdb", you would change "trunk/obj/release/nativelibs" to "voltdb/obj/release/nativelibs". Save this change. Exit the editor.


    Step 2: Build the full project using the "ant default" command from the root directory of your checkout. This will build the JNI shared library.


    Step 3. Start eclipse. Create a new Java project from existing sources. Eclipse will find your new .classpath file and correctly read the right buildpath and project directories. Just click through the next/finish buttons to finish the project wizard.

      .. and to answer your actual question

      Oops. I re-read your question and realized you might not be asking about eclipse. The directory structure is pretty straight forward. If you checked out http://.../trunk to a directory named voltdb, for example:


      voltdb/src/frontend -- the transaction management and messaging layers (Java)
      voltdb/src/ee -- the SQL and storage layers (CPP)
      voltdb/tests -- parallels the src directory and contains testcases.


      We build with the ant tool. By default, all object files are written to voltdb/obj/release. If you create a debug build (ant -Dbuild=debug default), the resulting files are written to obj/debug.

        Hi,


        Could you send me the updated README file?


        I tried Step1 and Step2, it worked fine.


        But for Step 3, after I created the project from existing source. It gave many errors. For example:
        tools/cli
        (default package)
        VoltdbCli.java


        package cli: the error says: the declared package "cli" does not match the expected package ""


        There are several errors like that one (for example: at src/proj_gen, tools/lbd_lock_test,....)
        Could you please check out a fresh version from trunk and try step 3 again?


        Thanks,
        Tuan
