Code showing error

[chaklader]

Dear folks,


I tried to run a c++ project that I made in Code blocks. I got it from my supervisor and my task it to run it properly. I have basic knowledge of C++ programming and now a days, trying to improve. In the time of compiling the the code shows lots of error. Anyone could help me to run it properly ? I heard that I need to install Intel TBB library but dont know how to do that. Errors are -

So, you are using a library, but it is not installed or otherwise available?

mungsmechanik\CFD Code\glbcls.h|5|error: /opt/tbb30_104oss/include/tbb/tick_count.h: No such file or directory|

Obviously there is no such file. Solve this first. There is really nothing we could do about it. Seems to be a tbb file, so google for tbb, that will bring up the official site. The go there and click on downloads. Pick the version you need. Follow the installation instructions.

[chaklader]

I guess that its from this page : TBB Home

Now I will try to install it and let you know again. However, thanks for the comments

[chaklader]

I downloaded the TBB for windows but there is nothing to install. Some folders named - bin, lib, doc, include, build, examples, src etc. src folder contains some c++ source and header file. Anyone knows how to use Intel TBB with a C++ project ?

[laserlight]

There may be a file named INSTALL.txt or similiar. Read it. It may amount to merely extracting the contents to a suitable location, possibly compiling the sources, and then including the relevant headers and possibly linking to the compiled library from your program.

[chaklader]

Thanks laserlight. However, there is only a text file Changes.txt that mainly confirms the modifications of the TBB from previous versions. I put my project in : D:\Lehrstuhl für Aerodynamik und Strömungsmechanik\CFD Code and installed the code blocks in : C:\Program Files\CodeBlocks. My intel TBB is here : D:\Lehrstuhl für Aerodynamik und Strömungsmechanik\Intel TBB\tbb40_233oss
I dont know where exactly I need to put that TBB stuff as there is no information and also which ones I need to compile. Same for the including header files as well.

They have documentation on the website. Since you are using Code::Blocks, your compiler is presumably g++, so follow the instructions relevant to GCC.

[chaklader]

Just to let you know that as header file I used #include "tick_count.h" but it seems still the same error is coming --> mungsmechanik\CFD Code\glbcls.h|5|error: /opt/tbb30_104oss/include/tbb/tick_count.h: No such file or directory|

[nvoigt]

Your compiler is probably right. There is no such file. It is included in the package you downloaded. Maybe you should read the documentation first, there is a "Getting started" guide on their page including a "Setup" step.

And if you can, drop the O-Umlaut from your path or replace it with oe. That's just a big problem waiting to happen. Don't use non-ASCII characters in programming. Ich hatte schon mehr als genug Probleme damit.

[chaklader]

Well, it is Germany

FYI: I never read anything about TTB before today and have still not used it.

Note: I am guessing windows based on the backslash in "mungsmechanik\CFD Code\glbcls.h".
It may make difference if it is CygWin, MSys, or MinGW setup.

From what I read the Windows Binary is for the Visual C++ Compilers(vc8,vc9,vc10).
Note: You can use the Visual C++ Compiler under Code::Blocks.
You need to determine what Compiler you are supposed to be using.

If MinGW G++ Compiler you most likely need to build it yourself or find a Binary build already done for it.
Note: I only looked at the OSS links on TBB site, it is possible the commercial version has MinGW GCC builds.
The clearest direction I found to build it for MinGW GCC; I only followed 6 Google links.
