hello,
I've read previous posts in this matter, and I've done all the necessary steps.
I've added "-fopenmp" to "Settings -> Compiler and debugger... -> Other options"
and "-lgomp -pthread" to "linker settings -> other linker options".
I still get the following message when I try to run the example code.
The program can't start because libgomp-1.dll is missing from your computer. Try
reinstalling the program to fix this program.
in the build log I get the following:
mingw32-g++.exe: unrecognized option '-pthread'
Process terminated with status 0 (0 minutes, 0 seconds)
0 errors, 0 warnings
I've seen in previous threads that another guy had a similar problem. he got a similar message to mine.
this was their reply:
The dll has to be in system path or in the exe's directory.
The easiest way is to add your MinGW's bin directory to the system-path.
how to I add my MinGW's bin directory to the system-path?
all the best

Do you mean:

and "-lgomp -lpthread" to "linker settings -> other linker options".
probably???
And btw: this would basically mean to link against the two libraries:
gomp and
pthread, so you can set this directly in the linker libs, not other options.
Please try to make yourself familiar with the idea of a linker and the interface to a linker.
Morten, "-pthread" is correct and it should be passed both to compiler and linker and it does more than just link to libpthread.
But I guess the problem is:
1. the compiler doesn't support openmp
2. the user should use -mthread or -mthread, but I've never tried to use openmp on windows, docs to the rescue
Hello again, and thanks for the quick response.
I've made the change from "pthread" to "lpthread" and the message still appears.
however, the line that said - mingw32-g++.exe: unrecognized option '-pthread' - is now gone.
that's a progress..
Hello, I have the same problem. Here is the answer
Compiler Setting>Other Options>fopenmp ；
Link Setting>Other Options> -lgomp -lpthread ；
If it shows cannot find libgomp-1.dll, just copy that file to the current project folde(IT WORKS FOR ME)r. Here is the way that I do. Some people said that you can add the path for liggomp-1.dll to codeblocks. I tried that way but it still doesn't work. Please let me know if you find a way works by adding the path to the system.
