these are the most helpful instructions i have found on the internet. im still in shock you helped me set up parallel programming after i've struggled for 3 weeks. thanks so much. and i just checked out your other videos, i enjoy the nintendo gameplay, but you really should put up more instructional videos.
Great work! For me, the turning point was finding the link to download 'minGW' (or mingw-get-setup.exe). There are so many minGW installers out there! Now, I can proceed with parallelizing my code. Thanks a lot.
Thank you buddy . I wasted nearly a week trying to code in openmp via linux through virtual box but virtual box was so slow that I couldn't even install Linux properly . Well this was fast and systematic.
OverTheHump If you could, that'd be great. Currently, it is impossible to use Code::Blocks for this. Even adding the .dll back in didn't work -- it was still complaining about a missing header file.
bro just do what he says step 1. install code blocks step 2. delete MinGW step 3. download MinGW installer and install it in a folder. step 4. copy the folder into your codeblocks folder and rename it as MinGW (i dont know if this is necessary). step 5. Go to settings -> compiler -> other compiler options, then enter -fopenmp step 6. linker settings tab -> add the dll file called libgomp-1.dll that is present in the bin folder of MinGW that we have copied. and in the other linker options area enter -lgomp -pthread step 7. tool chain executables tab -> click on auto-detect or choose the bin folder of the MinGW folder. thats all. it worked for me and hopefully it works for you too.
As of 17th april, 2017, the file 'libgomp-1.dll' is available in the MinGW version which I have downloaded from the link which has been provided in the description.
Thanks a lot! In DevC++ I did this: Menu -> Project -> Projetc Option (Ctrl + H) -> Parameters -> Linker -> Add Library or object. And looked for "libgomp.dll.a".
this means you're running it in a C++(cpp) compiler. stdio is a C library. To run it in a cpp compile it has to be otherwise use a C compiler to run and not a C++ one.
I linked the libgomp-1.dll and ad the -fopenmp as showed in the video, but when I run a code that uses omp.h ans #pragmas I take the following error: "pthreadGC2.dll is missing from your computer". Do you know what is the problem?
upon further investigation. it seems this happens regularly with cc1plus.exe, it is either out of date(a version before 4.2), or you are using the c compiler for a c++ code. either update to the latest gcc, or try using a different compiler by changing the compiler in tool-chain executables.
I linked the libgomp-1.dll and ad the -fopenmp as showed in the video, but when I run a code I got this error "stdio.h" file missing..Please help me asap.
Ankur Sethia If you are running this code using a C++ compiler, then you should include "cstdio.h" instead of "stdio.h". Note i used .c files which are NOT c++. the STanDard IO header file is called stdio.h in a .c file but is called cstdio.h in a .cpp file used in C++.
I had to change in Settings -> Compiler -> Toolchain executables -> Program files, that compiler used in "Linker for dynamics" and "C++ compiler" to be mingw32-gcc.exe since g++ doesn't exist in the new MinGW file.
pcsupport[dot]about[dot]com/od/findbyerrormessage/a/pthreadgc2-dll-not-found-missing-error[dot]htm Has suggestions for possibly recovering your missing DLL file. If all other options fail, download the DLL, and place it in the directory your executable is created. when it runs, the DLL will link and run.
If you are running the program using code::blocks' compile+run this problem should be relatively impossible... unless your system files are corrupted or missing If you are managing the files yourself however and running it in the command line from some working directory, then you could place a copy of the particular missing DLL in your working directory. Find this DLL and place it in the same directory location as the compiled executable, this WILL solve it. but, you must find out why its gone.
I want to stress that this is not an issue with Code::Blocks or OpenMP. If you follow my video move for move it should work, assuming you have no errors on your system. This DLL missing is a system issue, and this problem with your system should be resolved. That fact that this error showed up now and not some other time is most likely due to the nature of what you are doing not being typical of work on your system. my previous comments can lead you in the right direction.
In the Description I have a link to sourceforge[dot]net where you can download the latest mingw installer. only those in my club could access the college's site

I would suggest not using that compiler. I cannot verify that cc1plus.exe actually supports OpenMP. seeing as openmp[dot]org doesn't list it in the compilers that support it, and the compiler flag wasn't recognized, Its a safe bet to say it doesn't. The compiler you are using doesn't recognize it because it doesn't support it. I would suggest using: mingw32-gcc.exe for .c programs mingw32-g++.exe for .cpp programs they exist in the bin folder of the MinGW compiler sweet. support is guaranteed
2/26/2015: On Code::Blocks, required all of what the video is showing, plus pthreadGC2.dll. I downloaded the latter from www.dll-files.com. Cool videos on OpenMP from intel: TH-cam: Introduction to OpenMP by tim mattson. Cheers! :)
It's 2020 and we are still trying to figure out the same things.
"If you waching this video in 2020" got me emotional
OMG. Same here!!
lol same.
I got goosebumps when he said 2020 but the video is 10 YEARS AGO!
Its 2020 and our college professor still asked us to refer this video.........thanks man.
these are the most helpful instructions i have found on the internet. im still in shock you helped me set up parallel programming after i've struggled for 3 weeks. thanks so much.

I'm glad to see this video is helping people after this time, you are all welcome.
2022 and it still works fine for me, thanks for the video bro!
This video has now helped me twice when installing code::blocks. thank you
It's 2020 and it's still useful.
Thanks mate👍
Thank you buddy . I wasted nearly a week trying to code in openmp via linux through virtual box but virtual box was so slow that I couldn't even install Linux properly . Well this was fast and systematic.
MAAAAN Yeah, thanks a lot. you are number #1, you are millions of time better than those indian guys explaining omp installation on codeblock...
Thank you very very much! this is still working in 2023!
in the extra info dropdown menu, are links to the installer and code::blocks download. This way you don't need to worry about the Moodle at all. ^^
As of August 2016, it appears that MinGW no longer contains libgomp-1.dll ... not sure what to do about this.
That's unfortunate, I'll look into it and update with an annotation. I appreciate you pointing this out.

When I try to build: "C:\Program Files (x86)\CodeBlocks\MinGW\bin\libgomp-1.dll: file not recognized: File format not recognized
"
Why?!?
Hey I followed everything in the video but I’m not able to run the code it says that stdio no files or directory found
this means you're running it in a C++(cpp) compiler. stdio is a C library. To run it in a cpp compile it has to be otherwise use a C compiler to run and not a C++ one.
I linked the libgomp-1.dll and ad the -fopenmp as showed in the video,
but when I run a code that uses omp.h ans #pragmas I take the following error:
"pthreadGC2.dll is missing from your computer". Do you know what is the problem?
actually it's a useful video in 2019 :)
upon further investigation. it seems this happens regularly with
cc1plus.exe, it is either out of date(a version before 4.2),
or you are using the c compiler for a c++ code. either update
to the latest gcc, or try using a different compiler by changing the
compiler in tool-chain executables.

Glad to hear, you're welcome. good luck with your work.
It actually works,great job Thank you

I also checked my new minGW folder and the fact is that this file is not in my "include" folder.

It's still useful in 2020 thanks
Still useful in 2020!! Thanks :)
hello . 2:20 well... its 2021 and it too old but very helpful . thanks from the corona era
and how do you install openmp?
Problem fixed! I repaired the dll file.. Thanks for your answer
Thank you so much!
Does anybody knows how to run MPI code instead OpenMP. I can not find the name of a library that I should use.
www.mpich.org/static/docs/latest/
Library
#include
Ps: Probably to late Sorry
FYI: This video is still useful in 2020
This video really helps me a lot. Thanks.
Nice video, Keep it em coming!
Great video! It helped me a lot.
If you are running the program using code::blocks' compile+run this problem should be relatively impossible... unless your system files are corrupted or missing

awesome ,it works for me !!can you do similar thing on codeblocks on MinGW for MPI(say MPICH2 )
awesome :) thanks, Green
Great video! Thanks a lot!

thank you! Works..
Thanks a lot! ;)
mira quien encontre!
thanks was very helpful, just that I use -fopenmp to run it
Michial Da Boss doin Bigg thangs. lol nice voice!!!
Thank you!
got it. thanks
THANKS A LOT DUE. REALLY.

mingw32-gcc.exe for .c programs
mingw32-g++.exe for .cpp programs
they exist in the bin folder of the MinGW compiler sweet.
support is guaranteed
Legend!
i have to turn off anti virus to run the code :p
thx man
thanks :)
2020 and still trying to learn shit :) one day they make a program that pulls all the shit for every thing us noobs need. :)

happyyy studying...I hate my voice in this video ahahaha
Great 2021 [-:))
Thank you! This worked for me
Great video, it has really helped me!
Thank You So Much
Thanks very much! :)
thank you!!
