NetBean.C++11 clean setup with MSYS2

[DarioOli]

Using Netbeans without latest mingw-builds/MSYS 2 is almost useless. No one considered updating the package?
(and maybe providing a all-in-one installer? )

Using Netbeans without latest mingw-builds/MSYS 2 is almost useless.

Why? Standard MinGW (http://sourceforge.net/projects/mingw/) uses new GCC 4.8.1 and contains MSYS 1.0 package. Which sense in MSYS 2?

[DarioOli]

There are various reasons:

std::thread missing & other threading features missing
-http://mingw.5.n7.nabble.com/C-11-thread-support-in-4-8-1-td33129.html

code bloat.
mingw project add about 0.5MB for each compile unit that includes "iostream" while mingw-builds provides dlls to reduce code bloat from STL containers

also, MSYS 2 basically provide same functionality (except the fact neabeans refuse to use that by checking version number)

People using threading features of C++11 is using

MinGW-builds
XOR
MinGW-w64

both of wich are not the recommended package for Netbeans.

Also developers there reccomend MSYS 2.0:

http://sourceforge.net/p/mingwbuilds/mailman/message/32876748/

enough to bring attention of netbeans developers here?

I wrote thos instructions for MSYS2/MinGW-w64. I just installed it and it works with a simple project that sorts a few numbers. (Even with the MSYS2 MinGW-w64 builds) It works with the project set to C++11. Debug seems to work on it. I would need to try a C++11 project with C++11 features I suppose to see if there are problems with it, but I don't know C++ well enough and don't have time to work with it. If I had a C++11 sample project using threads, I could try it.

The NetBeans 8.0.1 v1.1 patch released Oct. 9th has some C++11 related fixes in it [1].

I built and ran the attached code with a thread as C++11 and it works except for if I use the Windows console, the NetBeans output window says "RUN FAILED (exit value -1, total time: 5s)" after I enter the number of values to sort. It runs to completion OK and debug seems to work ok regardless of this.





If I use Standard Output, I get no run failed message.

Also attached is a screenshot of the build tool versions.

CODE:

#include <iostream>
#include <iomanip>
#include <thread>

using namespace std;

int arrayVals;
int arr[10];
int minIndex, tmp;
int i = 0;

void PrintArray(int a[], int size) {
for (int i = 0; i < size - 1; i++)
cout << setw(2) << a[i] << ", ";
cout << setw(2) << a[size - 1] << endl;
}

void f() {
cout << "This program sorts a set of up to 10 numbers." << endl;
do {
cout << "How many numbers do you want to sort? ";
cout << endl;
cin >> arrayVals;
} while (arrayVals > 10);
cout << "Enter the " << arrayVals << " values: ";
cout << endl;
while (i < arrayVals) {
cin >> arr[i];
i++;
}
cout << endl;

for (int j = 0; j < arrayVals - 1; j++) {
minIndex = j;
for (int k = j + 1; k < arrayVals; k++) {
if (arr[k] < arr[minIndex]) {
minIndex = k;
}
}
if (minIndex != i) {
tmp = arr[j];
arr[j] = arr[minIndex];
arr[minIndex] = tmp;
PrintArray(arr, arrayVals);
}
}
}

int main() {
std::thread t(f);
t.join();
}

You main() function has not 'return'.'return 0;' will fix your "problem" with Windows console.

I still get "RUN FAILED" in the NetBeans output window while the program is still running in the Windows console waiting for the numbers to sort to be entered. It even does it on a single thread code like:

CODE:

#include <iostream>
#include <iomanip>

using namespace std;

void PrintArray(int a[], int size) {
for (int i = 0; i < size - 1; i++)
cout << setw(2) << a[i] << ", ";
cout << setw(2) << a[size - 1] << endl;
}

int arrayVals;
int arr[10];
int minIndex, tmp;
int i = 0;

int main() {
cout << "This program sorts a set of up to 10 numbers." << endl;
do {
cout << "How many numbers do you want to sort? ";
cout << endl;
cin >> arrayVals;
} while (arrayVals > 10);
cout << "Enter the " << arrayVals << " values: ";
cout << endl;
while (i < arrayVals) {
cin >> arr[i];
i++;
}
cout << endl;

for (int j = 0; j < arrayVals - 1; j++) {
minIndex = j;
for (int k = j + 1; k < arrayVals; k++) {
if (arr[k] < arr[minIndex]) {
minIndex = k;
}
}
if (minIndex != i) {
tmp = arr[j];
arr[j] = arr[minIndex];
arr[minIndex] = tmp;
PrintArray(arr, arrayVals);
}
}

return 0;
}

Can you check this code too:

Code:

#include <unistd.h>

int main(int argc, char** argv) {
sleep(30);
return 0;
}

[Mark Wilmoth]

Yes, after 5 seconds, the NetBeans output windows shows "RUN FAILED (exit value -1, total time: 5s)".
