I'm a total c++ Newbie.
I'm trying to build windows aplications with Wx-Widgets under Net Beans.
So far so good. I have instaled everything, configured, build wx-widgets and attached it to the new project - with help of a good man here: Can't make wx-widget work with net-beans.
Now I try to build my first app:
#include <wx/string.h>
int main(int argc, char **argv)
{
wxPuts(wxT("A wxWidgets console application"));
}
and this is what I get:
I'm not sure if this is readable so I paste the errors:
g++ `C:\WXWIN\wx-config --cxxflags` -c -g -I../../../WXWIN/include `C:\WXWIN\wx-config --cxxflags` -MMD -MP -MF build/Debug/MinGW-Windows/main.o.d -o build/Debug/MinGW-Windows/main.o main.cpp

Please notice that I have set everything in linker and compiler like ordered: http://wiki.wxwidgets.org/Compiling_using_Netbeans
The error is right in front of you: "command not found". If you use /bin/sh, you must use Unix style paths, e.g. C:/WXWIN/wx-config instead of DOS paths with the backslashes.
I seriously advise you to get familiar with the environment you're using instead of just following the Wiki instructions without understanding them, otherwise your problems won't be over any time soon.

I am trying to do unit testing with C++/Codelite. I have UnitTest++ plugin installed from codelite-plugins package (Ubuntu 18.04). I can also see this:
$ ls -la /usr/include | grep Unit
drwxr-xr-x 3 root root 4096 Mar 2 11:47 UnitTest++
$ sudo dpkg -l | grep unittest++
ii libunittest++-dev 2.0.0-2 amd64 unit testing framework for c++, static library and headers
ii libunittest++2:amd64 2.0.0-2 amd64 unit testing framework for c++, runtime library
So I create a test project in Codelite and I add this:
#include <unittest++/UnitTest++.h> // This line and main are auto-created
TEST(SanityTest)
{
CHECK_EQUAL(1, 1);
}
int main(int argc, char **argv)
{
return UnitTest::RunAllTests();
}
Now I would expect test results after I press CTRL+F5. But when I do, I only get a popup window saying there are no tests:
I also noticed that when I go to Build > Build Project I get an error message:
fatal error: unittest++/UnitTest++.h: No such file or directory
I also found THIS ANSWER and tried different variation of console commands as per answer/comments there, but I always get the same no such file or directory error.
Any idea what I am missing?
EDIT:
Build log as per Stephen's Newell request:
/bin/sh -c '/usr/bin/make -j8 -e -f Makefile'

Also if I right-click the project, go to Settings > Compiler, I can see:
Included Paths = /usr/include/unittest++
Based on your ls output, it looks like you should change your first line to this:
#include <UnitTest++/UnitTest++.h>
I'm not sure why the answer you linked to worked with a lowercase directory name; the examples in the project documentation all use the mixed-case directory name.
I'm a fresh c++ user in Windows 8 system. I have installed MinGW and setup the environment variables. I create the simplest hellow world code as below
#include<iostream>
#include<vector>
using namespace std;
int main(int argc, char **argv)
{
cout<<"hello world"<<endl;
return 0;
}
It works well at the first time, but when I do some small modification, for example delete "hello", and then build and run the project again. I found that the program will keep running without end. The command line keeps showing:
Current working directory: C:\Users\cr\Documents\project\helloworld\Debug
Running program: le_exec.exe ./helloworld
If I try to build it again, it shows
make.exe[1]: Entering directory 'C:/Users/cr/Documents/project/helloworld'
C:/Users/cr/MinGW/bin/g++.exe -c "C:/Users/cr/Documents/project/helloworld/main.cpp" -g -O0 -Wall -o ./Debug/main.cpp.o -I. -I.

make.exe[1]: Leaving directory 'C:/Users/cr/Documents/project/helloworld'
make.exe: *** [All] Error 2
Makefile:4: recipe for target 'All' failed
====1 errors, 0 warnings====
I could not even delete the executable file "helloworld.exe" because it is using in 'System' until I restart the computer.
Update:
I can compile it in the command line:
C:/Users/cr/Documents/project/helloworld>g++ main.cpp -o test.exe
C:/Users/cr/Documents/project/helloworld>test.exe
It will then keep running until I close the command line window. If I open a new command line window and compile the file again. There is no problem.
Update2:
Problem also happens when I compile the cpp file the second time even if the file has not been edited.
C:/Users/cr/Documents/project/helloworld>g++ main.cpp -o test.exe
C:/Users/cr/Documents/project/helloworld>test.exe
hello world
C:/Users/cr/Documents/project/helloworld>g++ main.cpp -o test2.exe
C:/Users/cr/Documents/project/helloworld>test2.exe
It keeps running here.
Thanks all, I struggled with it for a whole day. The problem is anti-virus software...... I set it inactive and all things do well...
I don't want to point out what this software is, but just want to give out a reminder for this problem....
I've got Netbeans C/C++ set up, Cygwin installed, configured and running correctly. SDL was installed from the sources using the Cygwin terminal. I've confirmed that Cygwin, Netbeans and SDL are all running correctly, I can write and compile C++ projects just fine with Netbeans and Netbeans can see SDL without having to include any files or anything, it just works like the default libraries.
#include <cstdlib>
#include <sdl2/SDL.h>
using namespace std;
int main(int argc, char** argv) {
return 0;
}
That's the code I'm trying to compile, Netbeans doesn't highlight the include for sdl.h, but when I go to build I get this:
"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

The build is successful when I don't include SDL. Anybody know what I'm doing wrong?
The error message looks really evil - but it just tells you it can't find a WinMain.
This is a known issue with SDL. Please add those libraries to your linker (order is mandatory!):
mingw32
SDLmain
SDL
You can either add -lmingw32 -lSDLmain -lSDL to linker options or add them through the library menu of linker config.
It's possible you need SDL_mixer too - if so, just add it last.
Please see also: http://content.gpwiki.org/index.php/SDL%3aTutorials%3aSetup
As a "dirty workaround" you can do this: undefine main.
SDL redefines main() as a macro with some additional stuff. You can verify this by egl. Ctrl + click on main / go to declaration / definition or check if it's formatted as makro.
#include <cstdlib>
#include <sdl2/SDL.h>
using namespace std;
/*
* If 'main' is defined we clear that definition
* to get our default 'main' function back.
*/
#ifdef main
# undef main
#endif /* main */
int main(int argc, char** argv) {
return 0;
}
Please see source of SDL_main.h (line 103+).
PROBLEM SOLVED
Go to bottom to see the solution.
Hello everybody i've been googling' looooong time and I didn't find anythinig, so, here we go:
I have this setup:
Compiler: MinGW IDE: Netbeans Library: SDL Language:
C++
Okey, so, i have included this folder: "C:/SDL_1.2.15/include"
And Linked those libraries in this order:
-lmingw32
-lSDL_main
-lSDL
Then if I use a normal program without the #include "SDL/SDL.h" then compiles okeey.
So if i include the SDL header file the IDE gives me greenlight to compile an then, i get this output:
"C:/WinAVR-20090313/utils/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
make[1]: Entering directory `C:/Users/pablo/Documents/NetBeansProjects/SDL_Test'
"C:/WinAVR-20090313/utils/bin/make" -f nbproject/Makefile-Debug.mk dist/Debug/MinGW-Windows/sdl_test.exe
make[2]: Entering directory `C:/Users/pablo/Documents/NetBeansProjects/SDL_Test'
mkdir -p build/Debug/MinGW-Windows
rm -f build/Debug/MinGW-Windows/main.o.d
g++.exe -c -g -Wall -I/C/MinGW/include -I/C/SDL-1.2.15/include -MMD -MP -MF build/Debug/MinGW-Windows/main.o.d -o build/Debug/MinGW-Windows/main.o main.cpp
make[2]: Leaving directory `C:/Users/pablo/Documents/NetBeansProjects/SDL_Test'
make[1]: Leaving directory `C:/Users/pablo/Documents/NetBeansProjects/SDL_Test'
main.cpp:11:21: error fatal: SDL/SDL.h: No such file or directory

make[1]: *** [.build-conf] Error 2
make: *** [.build-impl] Error 2
BUILD FAILED (exit value 2, total time: 2s)
So! Here is the source code of my application, it only has a 'main.cpp' file:
/*
* File: main.cpp
* Author: pablo
*
* Created on 1 de septiembre de 2013, 23:20
*/
#include <cstdlib>
#include <windows.h>
#include <SDL/SDL.h>
using namespace std;
/*
*
*/
int main(int argc, char** argv) {
return 0;
}
I've found new issues; When I remove the #include (comment //) then the console throws me this errors instead the 'no such file or directory':
c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -lSDLmain
c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot find -lSDL.dll
When I compile without #include using Cygwin compiler, the project builds correctly.
Found another issue:
make[2]: *** No rule to make target `/C/SDL-1.2.15/lib/libSDLmain.a', needed by `dist/Debug/MinGW-Windows/sdl_test.exe'. Stop.
this happens when I add the full path to the SDL libraries instead of -lSDL.dll and -lSDL_main
SOLUTION:
The problem solves coping c:/SDL-1.15/include/SDL/ folder to c:/MinGW/include/ directory, and libraries from lib on c:/SDL-1.15/lib/SDL to MinGW/lib
You have to add the headers separately.
It's not enough to do the include, you have to do multiple things to add a thing like SDL in your project.
I installed the NetBeans IDE 7.3.1 almost a week ago and still haven't been able to get it to compile anything.
I'm using the Cygwin's compiler for C/C++, and I get the following error message for a simple "Hello World" program:

EDIT
I fixed this by just making a new toolkit and adding the base directory as Cygwin -> bin.
The problem now is that I keep getting
Unable to start pty process
gcc: Command not found
You should check whether you have installed gcc (plus gdb and make)
via MinGW:
MinGW+NetBeans (just look at the screenshots, you don't have to understand Hungarian)
via Cygwin:
http://www.eecg.utoronto.ca/~aamodt/ece242/cygwin.html
You should also check whether paths are correct in NetBeans:
Tools > Options > C/C++ > Build Tools:
(At the time of creating the screenshot, I had MinGW installed in C:\Programs\MinGW, BUT if you have it installed in C:\MinGW (which is the default), this correct, too! The only important thing is that you should install MinGW in a path which doesn't contain whitespaces.)
This is what it looks like when paths are incorrect, letters are red:
Note: I have MinGW installed, but it doesn't change the fact that you should check whether YOUR paths are correct.
You should also take care the right Configuration is selected in project Properties (right click on project) > Build - The right "Tool collection" has to be selected (on which the paths above are correct):
Unable to start pty process
Related answer: Can build, but can't run C code in netbeans (but it works in command line)
So right click on the project, Properties > Run > Console Type > External Terminal (instead of e.g. "Internal Terminal"). Here is a screenshot:
Here is your problem:
gcc: Command not found
Cygwin is not a compiler, it's a unix-like environment for Windows. Gcc is the compiler. You have to install gcc with Cygwin before it will work.
