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!!

Answer 1

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.

Answer 2

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 https://netbeans.org/community/releases/72/cpp-setup-instructions.html#compilers

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.
