#20 Dev-C++ x64 won't compile OpenMP code

[sfinexer]

The code:

# include <cstdlib>
# include <iostream>
# include <omp.h>
using namespace std;
int main (int argc, char * argv [])
{
   int i, j;
   j = 0;
   # pragma omp parallel for
   for (i = 1; i <1000; i ++)
   {
     j = j +1;
   }
   cout << j;
     system ("PAUSE");
     return 0;
}

does not work in Dev-C + + x64

What errors are you getting exactly? It compiles fine here and produces 999 as a result (duh). Are you expecting specific assembler output?

And ehm, please read formatting help, and use the provided code tags.

<omp.h></omp.h>

do not have the 64 version

pthreadGC2_64.dll
and
pthreadGC2_64.dll
none

[sfinexer]

*libgomp_64-1.dll

[sfinexer]

The compiler of such a library is not present.
He basically can not compile the code
Swears to include <omp.h></omp.h>

If you want I can make a video!

[orwelldevcpp]

Sure, if it helps me to understand the problem.

[orwelldevcpp]

I understand the problem now. I left out the threading dlls to make the TDM-GCC x64 package smaller. Will readd them to Dev-C++ 5.2.0.4 or 5.3. In the mean time, you can get them from the TDM-GCC site: http://tdm-gcc.tdragon.net/download

Without multi-threading computing too long my program works.
I need parallels cycles.

[orwelldevcpp]

The final version of Dev-C++ 5.3 will fix all your problems. Until that version is released, please try:
- Download TDM-GCC x64 (33MB)
- Install it somewhere, and enable the 'openmp' option during installation
- Overwrite the MinGW64 folder of Dev-C++ with the created MinGW64 folder.
