Required Software

NetBeans IDE 5.5.1 or NetBeans IDE 5.5 must be installed before you attempt to install NetBeans C/C++ Development Pack 5.5.1 update 1.

NetBeans C/C++ Development Pack 5.5.1 update 1 runs on the Java 2 Platform Standard Edition Development Kit 5.0 Update 1 or higher (JDK 1.5.0_01 or higher), or JDK 6.0, which consists of the Java Runtime Environment plus developer tools for compiling, debugging, and running applications written in the Java language.

You can download the JDK for your platform from http://java.sun.com/j2se/1.5.0/.

Configuration Information

The NetBeans IDE has a default heap size of 128 MB. NetBeans C/C++ Development Pack runs well with this default setting when you are developing small projects with up to 500 source and header files.

When you are developing larger projects, you will need to increase the heap size. If you get an OutOfMemory exception when developing a large project, the heap size is a likely cause.

You can set the heap size for the Java Virtual Machine (JVM)* on which the NetBeans IDE runs in the netbeans.conf file.

To change the heap size:

  1. Copy the netbeans.conf from the etc folder in the NetBeans installation directory into your NetBeans user directory ($HOME/.netbeans/5.5.1).
  2. In the netbeans.conf file in your user directory, edit the -J-Xmx command line Java startup switch (bolded below) in the netbeans.conf file, and then restart the IDE.
    # command line switches
    netbeans_default_options="-J-Xms32m -J-Xmx128m -J-XX:PermSize=32m 
    -J-XX:MaxPermSize=96m -J-Xverify:none -J-Dapple.laf.useScreenMenuBar=true"
    

The recommended heap sizes for NetBeans C/C++ Development Pack for medium and large applications are:

  • For developing medium applications (500-2000 source and header files) on a system with 1 GB or more of RAM: 512 MB
  • For developing large applications (more than 2000 source and header files) on a system with 2 GB or more of RAM): 1 GB

Do not increase the heap size to more than 1 GB.

If you are running the Sun JVM, you can also add the garbage collector switches -J-XX:+UseConcMarkSweepGC (concurrent collector) and -J-XX:+UseParNewGC (parallel collector) to the netbeans.conf file. These options allow the garbage collector to run in parallel with the main execution engine. They might not be supported by non-Sun implementations of the JVM.

For more information on NetBeans switch settings, see the Configuring the IDE section of Using NetBeans IDE 5.5 (Archived document)

For more information on NetBeans performance tuning, see Tuning JVM Switches for Performance.

* Note: The terms "Java Virtual Machine" and "JVM" mean a Virtual Machine for the Java(TM) platform.

Known Issues

This NetBeans C/C++ Development Pack 5.5.1 update 1 release lets you explore and evaluate new functionality in the IDE. We encourage you to get involved and give us feedback by logging any issues you encounter in the Issue Tracking system at https://netbeans.org/community/issues.html.

The unresolved issues for this release are as follows:

  • Issue #89880: Project is not reparsed when Compiler Collection is switched

    Description: If you switch compiler collections for a project, the project is not reparsed. After the switch, code completion and hyperlinks might not work properly for the project.

    Workaround: Close the project and open it again.

  • Issue #76173: No automatic flush of output before input

    Description: If a projects default Console Type property is changed from External Terminal to Output Window (output only), then no input can be typed into the Output window.

    Workaround: In the Running category of the project properties, change the default Console Type property only for output-only applications.

  • Issue #89343: Pause doesn't work on Windows when program waits user input

    Description: Clicking Pause while a program is waiting for input does not stop the program. Pause works only after you supply the input.

    Workaround: No workaround.

  • Issue #90120: "pause" (on Windows) does not work on a corner case

    Description: Besides 89343, there are several other cases when Pause does not work on Windows. One case is in very tight loops.

    Workaround: No workaround.

  • Issue #90222: Breakpoints don't take immediate effect while running

    Description: If a breakpoint is set on a running process, the breakpoint is not passed to gdb until the next time the process is stopped.

    Workaround: Pause the process, set the breakpoint, and continue.
