java.lang.NullPointer Exception when running C++ Programs in Netbeans 7.2

Question

I wanted to try my hands on C++ and wanted to use the same netbeans IDE since I have being using it for sometime for Java development. I downloaded the Cygwin tools and set up the IDE accordingly. When I try to run the application it says that the build was successful...,

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
make[1]: Entering directory `/cygdrive/c/Users/LJee/netbeans/tut-install/CppApplication_1'
"/usr/bin/make"  -f nbproject/Makefile-Debug.mk dist/Debug/Cygwin-Windows/cppapplication_1.exe
make[2]: Entering directory `/cygdrive/c/Users/LJee/netbeans/tut-install/CppApplication_1'
make[2]: `dist/Debug/Cygwin-Windows/cppapplication_1.exe' is up to date.
make[2]: Leaving directory `/cygdrive/c/Users/LJee/netbeans/tut-install/CppApplication_1'
make[1]: Leaving directory `/cygdrive/c/Users/LJee/netbeans/tut-install/CppApplication_1'


BUILD SUCCESSFUL (total time: 450ms)

But the program will not run. It throws a Java Null pointer exception.

java.lang.NullPointerException


RUN FAILED (exit value -1, total time: 26ms)

Since there are no Java code in C++ programs this has to be an issue with the IDE. I saw this thread in the Netbeans forum http://forums.netbeans.org/topic52231.html

Here the user has changed the IDE version which I don't want to do.

Is there anyone out there who has come across this situation who can help me out. I'll be glad! Thanks in advance!!

Try NetBeans 7.3, and see if it fixes the problem. – Haugen

Thanks @MattBall, I don't want to upgrade. I found the solution you have to add the Cygwin path (C:\cygwin\bin) to the environment path variable then it works fine? Look at link – Latif

Answer 2

I had the same problem under Linux Mint 18 Cinnamon with Netbeans 8.1 and I solved it by right-click the project name item -> Properties -> Run -> Console Type -> "Standard output"

After that the "Run" command worked perfect.

This is the correct answer. (Same issue w new build of NetBeans 8.1 under Lubuntu.) Although I prefer External Terminal. The default of Internal Terminal appears to be a lose. – Larrisa

This solved the same problem in NetBeans 8.1, installed in Ubuntu 16.04 LTS. – Steadfast

Answer 3

I encountered the same issue when I upgraded Ubuntu from 14.04 LTS to 16.04 LTS and upgraded NetBeans IDE from 8.0.2 to 8.1 via Synaptic. I guess my JVM installation was messed up. My solution was to uninstall NetBeans 8.1 with Synaptic and then download and install the same version 8.1 from https://netbeans.org/downloads/ (all-in installer). It fixed the issue.
