Hello I’m trying to create a block which C++ code needs to use include “vector.hpp”. But I;m getting this error: fatal error: vector.hpp: No such file or directory. Is there a way to do this? Thank you very much. – View this message in context: [http://gnuradio.4.n7.nabble.com/include-vector-hpp-tp54344.html](http://gnuradio.4.n7.nabble.com/include-vector-hpp-tp54344.html) Sent from the GnuRadio mailing list archive at [Nabble.com](http://Nabble.com). ---

Hi, Try dropping the “.hpp” portion of your include. This file does not have any extension and is usually included as follows: #include Hope this helps, Michael ---

Hi Yes, I tried to use only #include , but it gives me an error for each vector a I use. Vector f (at the beginning the following code) is one of the vectors which needs the #include “vector.hpp”. intentooptimizar.cpp [http://gnuradio.4.n7.nabble.com/file/n54350/intentooptimizar.cpp](http://gnuradio.4.n7.nabble.com/file/n54350/intentooptimizar.cpp) Thank you. – View this message in context: [http://gnuradio.4.n7.nabble.com/include-vector-hpp-tp54344p54350.html](http://gnuradio.4.n7.nabble.com/include-vector-hpp-tp54344p54350.html) Sent from the GnuRadio mailing list archive at [Nabble.com](http://Nabble.com). ---

It looks like you are trying to create your own vector class named Vector (keeping notice of the capitalized ‘V’). These Vector method definitions need a definition for the Vector class, which is presumably in your Vector.hpp. I would like to note that the .hpp extension indicates a template header library, and all of the method definitions should be inline in the template class definition, or in an include file; not in a compiled object file. It appears (at least from this lone file) that you are not using std::vector at all, and you may wish to remove the '#include ’ line to keep things clean in your code and not include not used pieces of code. Back to your example not working, your #include “Vector.hpp” must point to the file that presumably contains the class definition. for this include to work as stated, the Vector.hpp file will have to be in the same directory as the file that you posted; otherwise you will have to give a relative (or absolute) path to this file in the include statement. I hope this helps you some! Michael P.S. Why are you not using std::vector? ---

Hi! Um, there’s no vector.hpp in GNU Radio; are you maybe referring to the header that contains std::vector? You would normally include that as #include and let your compiler figure out the file name suffix. Best regards, Marcus ---

Why are you not using std::vector? David, While I’m kind of curious about you making your own vector class, too, this is not about GNU Radio but generally C++ coding issues. Please move this conversation to a more appropriate forum about programming. Thanks, Tom ---

Hello! I think I already found a way to do this, but now I’m getting this error: “error: a function-definition is not allowed here before ‘{’ token” In these parts of the code : Vector txyz(4); void initialize() { txyz[0] = 0.0; txyz[1] = 0.0; txyz[2] = 1.0; txyz[3] = 0.0; } void PrimercruceenB() { char B; char Bi; double w = sqrt(b \* (r - 1)); while (txyz[1] \< w){ // Cruce con plano B en x ``` RK4Step(txyz, dt); ``` } // Aqui ya tengo el primer valor de x cruzando al plano B ``` if (txyz[2] >= w) { // Cruce con plano B en y Bi = '3'; } else { while ( txyz[2] < w) { RK4Step(txyz, dt); } if (txyz[1] >= w) { Bi = '3'; } } ``` } Vector f(Vector txyz) { double t = txyz[0]; double x = txyz[1]; double y = txyz[2]; double z = txyz[3]; Vector f(4); f[0] = 1; f[1] = - sigma \* x + sigma \* y; f[2] = - x \* z + r \* x - y; f[3] = x \* y - b \* z; return f; } I don’t know why I’m getting this error. Doesn’t these functions can be recognize by GNU Radio?

I’m sorry, but there is no indication of that in your original email about the code. It was just what looked like your own code; not inside a GNU Radio block. Most likely, you have not properly added your class files to the build processing CMakeLists.txt. Also, where is your original post? Please keep the thread readable when replying by keeping the relevant parts of the conversation in the replay and bottom-posting like this. Tom ---

Hi David, GNU Radio block or not, what you’re seeing is C++ error, and your code is not really related to GNU Radio. Since GNU Radio is written in “normal” C++, you must have made some syntax mistake when integrating your code into the template that you get when creating a new block. However, that template is just a bunch of normal C++ files containing normal classes (that’s what GNU Radio is – C++ files containing classes); we’re typically pretty resource- and helpful when it comes to solving issues that arise when dealing with GNU Radio code, but what you’re giving us has no indication of where things go wrong, and how you use that code in your C++ class. All we can tell you is that a) you seem to have done it wrong and b) you might really need to learn how to read and communicate compiler errors, so that you might yourself understand better what goes wrong and how to ask for help in a manner that allows people to see what’s wrong. So: Make sure you find out where you didn’t write correct C++. Best option is always to have someone who is a bit more used to that sit next to you, and tell her/him “I wrote this code, and when I try to compile it, I get this error”, and then let that person explain to you how they approach figuring out where the problem lies. Even if the two of you don’t really figure out the problem, that will lead to the both of you learning about debugging – which is really invaluable! If you can’t solve the problem, it’s really O.K. to ask somewhere, but please make sure to offer all information one might need to understand the problem; in your case that mail would have looked something like: “I have wrote a couple of C++ \ to . Now, \ compiles fine, but when I insert these \ into my newly created block (gr\_modtool add \), the following \ doesn’t compile. I get the error \.” Then, it would have been easy for us to understand the connection to GNU Radio, to actually see where things went wrong, and to analyze the error – all things that you might have already guessed were important to the solution. But I have to agree with Tom quite a bit: what you’re having are mainly C++ problems, and they don’t seem to be very GNU Radio-specific. So probably sitting with someone who knows C++ (but doesn’t know GNU Radio) makes much more sense than asking us, who know GNU Radio (and a bit of C++) but don’t have the chance to sit next to you and talk to you about what your code does/should do and interactively explore what you do. Best regards, Marcus
