I had read this link, but obviously that link is for people who already know everything about CMake and compiling and linking… which was not my case, so that was all Greek to me Luckily some copy-paste and a lot of trial and error finally did the trick anyway.I’ve been reading a book by one of the CMake guys called “Professional Cmake.” It’s an amazing book and has been a daily tool for me lately. The canonical link for “how do I use CMake with ROOT and my own binary?” is I came up with this CMakeLists.txt file which I almost understand - I still didn’t take any course on compiling but I managed to get things together. I was hoping to do that without spending time on learning about linking and compiling, but it seems like that wasn’t possible. Obviously, for an IDE to be aware of the ROOT classes, it does need to parse the necessary ROOT code, and that was my goal. The point of this thread was to set up an IDE where coding for ROOT was easier than using a plain text editor. In fact, that was still the way I planned to execute my ROOT code.

The goal of this is exactly to simplify the life of people who don’t want to learn compiler and linker flags! You can run root -l -b mycode.C to start it from a match / grid submission script. ROOT offers a top notch C++ interpreter that runs code at the speed of a compiled program. In interactive mode doesn’t throw any error. My ROOT installation seems to be fine, though, since TF1* func = new TF1() Vector.tcc:32:10: note: in file included from /home/renyhp/Programmi/root/include/Vc/scalar/./common/./sse/vector.tcc:32: Vector.h:496:10: note: in file included from /home/renyhp/Programmi/root/include/Vc/sse/vector.h:496: Vector.h:35:11: note: in file included from /home/renyhp/Programmi/root/include/Vc/common/./vector.h:35: Vc:30:10: note: in file included from /home/renyhp/Programmi/root/include/Vc/Vc:30: Types.h:18:10: note: in file included from /home/renyhp/Programmi/root/include/Math/Types.h:18: TFormula.h:24:10: note: in file included from /home/renyhp/Programmi/root/include/TFormula.h:24: TF1.h:27:10: note: in file included from /home/renyhp/Programmi/root/include/TF1.h:27: Main.cpp:2:10: note: in file included from /home/renyhp/Scrivania/vediamoseva/main.cpp:2: Main.cpp:1:1: note: in file included from /home/renyhp/Scrivania/vediamoseva/main.cpp:1: Gatherimplementation.h:73:21: error: 'vector_size' attribute requires an integer constant As soon as I try to #include it, I get a popup saying Warning: The code model could not parse an included file, which might lead to slow or incorrect code completion and highlighting, for example. (I can confirm that $ROOTSYS/lib/libMatrix.so.6.16 is an existing file.)Īlso, I suspect something may be broken about TF1.h. I get error while loading shared libraries: libMatrix.so.6.16: cannot open shared object file: No such file or directory (Is there any way to make QtCreator find automatically the header file to be included while I type, e.g., TH1F in my code?) However, if I try to run my project, which only has one file named main.cpp, which looks like this #include This does make QtCreator recognize ROOT classes after I #include the appropriate header file. I only have some vague idea about what those lines do this is basically a copypaste from other threads. My CMakeLists.txt currently looks like the following: cmake_minimum_required(VERSION 2.8) I am aware the ROOT forum is maybe not the best place where to ask to help for my issue I am hoping that, in that case, someone can point me a more appropriate forum to ask, or some tutorial where I can learn how to deal with this. (the same code works well if I work in interactive mode in ROOT, so I assume it’s some KDevelop error).Īlso, if I try to build the project, this error occurs: fatal error: TF1.h: no such file or directory This generates the following error in the parser Unknown type name 'TF1' did you mean 'Vc_1::TF1'? However, this doesn’t seem to be enough first of all, the parser will give me errors when I try to use the TF1 class, like this: #include This makes KDevelop recognise ROOT classes so for example I get the auto-completion for TString, or I can make it insert automatically #include. Now what I managed to do is creating an empty CMake project, and configuring it so that $ROOTSYS/include is added to the parser (via Project > Open Configuration… > Language Support).

I have found this post by suggesting to use KDevelop, which would fit perfectly to my case since I’m already on Kubuntu and using KDE.

I would really love to setup an IDE, but I am not very familiar with similar tasks. I have worked a bit with ROOT macros and always used simple text editors.
