How can i resolve this?
I keep running into this error, even though the first few times i built and ran something it worked perfectly, and since I'm new to CodeBlocks (or any IDE/Compiler for that matter) what to do.Any code i put in, it'll give me this error....

I have defined overloaded operator as follows in the header file but in the cpp file of the class it gives error.
friend vli &vli::operator + (int &a,vli &obj);
How to define it in cpp file of my class?
Today I experienced a very strange compiler issue. I started the compilation and it outputted that a member object of a class was undefined. After about 4 hours of trying the find the bug I commented and then uncommented said line of code that was undefined. Sure enough the compilation worked just from commenting and uncommenting.
I am using Microsoft visual studio 2012 express. Due to the size of the project, I should know the cause because it may cause more problems further down the line. I feel that it might have something to do with the compiler not having a proper order of compilation for the header files and that I might need something to solidify the way that the header files are processed. The below code is a fragment of a header file.
class CInGameSection: public CBaseGameSection {
public:
CInGameSection(bool isInEditor, bool creatingNew, COutput& output, string saveSlot, string regionName, horiVertiVals * widthAndHeight);
~CInGameSection();
bool update(CInput & input, CAudio & audio, COutput & output);
void output(CInput & input, CAudio & audio, COutput & output);

We have a midi.cpp which includes midi_synth.h.
this h file declares a class and this class inlines a open method.
Now the linker doesn't recognize this open method when called by another method inside midi.cpp.
What would I do?

Working on a basic class program and I'm generating two compiler errors that I'm not sure how to fix. Header file, implementation cpp and main cpp are shown below. The specific errors are shown after the code.

The file generates the second error, C2228, at lines 37-41 and 43. Basically where I tried using the second created object. Error message is "left of '.setFirstName' must have class/struct/union"
Working on a solution involving inheritance. The whole solution is pretty massive at this point so I'll just focus on the problem areas. I'm getting a lot of "redefinition" and "undefined class type" compiler errors, including C2370, 2011, 2504, and 2027, in Benefit.h, Employee.h (the constant members are a big occurance) I'm also getting 2027 and 2079 in EmployeeMain.cpp. with my Benefit and Employee object calls.
Clearly I missed something in about how to code this correctly. Sadly the course textbook focuses on general OOP theory instead on the accompanying C++ syntax.

My compiler (GCC) keeps expecting an expression where it shouldn't in 1 specific piece of my code:
int zxcNewWindow( HWND parent, TCHAR *text, zxWINDOW *kid,
UINT style, int x, int y, int w, int h, int type )
// right here
{
*kid = zxDefWINDOW;
The project contains only 2 files right now and the settings are just the default for an empty Code::Blocks 12.11 project. Both files are in UTF-8 format (tried in ASCII too), I just cannot see why this is not compiling correctly. I'll post the files in the next two posts.
Edit: For those of you who didn't get what the error was from the above here's the full log:
mingw32-gcc.exe -Wall -g -DzxDEBUG -c C:MePrjscppzxGUImain.c -o objmain.o

I created a class called Point, in Point.h
I created a class called Rectangle in Rectangle.h and Rectangle.cpp
If I create an int main() function in Rectangle.cpp (that includes Rectangle.h), I can compile Rectangle.cpp and run the resulting program. Fine.
Question:
I create a separate file called main.cpp. I include Rectangle.h. But now the compiler complains.
Code:
$ g++ main.cpp -o main
/tmp/cc38JIph.o: In function `main':
main.cpp:(.text+0x26): undefined reference to `Rectangle::Rectangle(int, int, int, int)'
main.cpp:(.text+0x32): undefined reference to `Rectangle::getArea() const'
collect2: ld returned 1 exit status If I can create a class in Point.h and use it in Rectangle.h, why can I not just use Rectangle in main.cpp?
And the files, of course:
file: main.cpp

#include <iostream>
#include "Rectangle.h"
using std::cout;
using std::endl;

Well, I thought I had this program working but now I'm getting the above referenced compiler error. The program is just a basic user interface. It is for a classwork assignment.
The program is to accept user information as a string, convert it (if needed) to either the int or double variable, and then display the result. I'm using stringstream convert to make the change between types, but I'm not sure if I'm using it right (that might be what's causing the error, I'm not sure). Line 36-37 generates the error.

#include <iostream>

Having issues with program to create a shape area calculator with circle square and rectangle. the uml goes as follows:
Where the UML has shape as the abstract class with public area():double, getName():string,and getDimensions:string, rectangle derived from shape with protected height, and width, and a public rectangle(h:double, w:double), followed by a derived square from rectangle with just a public square(h:double), and finally a circle derived from shape with a private radius, and a public circle(r:double).

I would have expected a multiple defnition error when linking the two .c files. as in both the files, with the 'int variable' command, the variable 'variable' is defined (memory allocated) and during linking the linker doesnot know which variable to link to.
I get an error though when i use "int variable =123;" in the header file instead of the "int variable;" statement. i dont understand as in both the cases the variable is defined (memory is allocated) and the linker should give a multiple definition error.
Here is my code,
Code:
class A {

void display() {
cout<<"A"<<endl;

The compiler error is "error C2039: 'display' : is not a member of 'SP<T>'". What am I missing here?

I am trying to compile some code under opensuse 12.2. The code compiles fine under cygwin and CentOS. Under suse, I get the error "directory name must immediately follow -I"
This is the place in make where the error happens.
Code:
g77-3.3 -I ./src/src_common_depend/ -O2 -DVERNUM=6 -c -o bld_dir/FortranA.o src/src_client_main/FortranA.FOR
f771: error: directory name must immediately follow -I
The includes are specified in the make file with,
SOURCELOC = ./src
INCLUDES = -I ${SOURCELOC}/src_common_depend/
These are common includes that are used by more than one applications and so are stored in a common location.
I have tried leaving off the ./ and the trailing /
SOURCELOC = src
INCLUDES = -I ${SOURCELOC}/src_common_depend
And various similar combinations, including parenthesis instead of the curly braces.
I'm not sure why gcc under suse would be particular about this syntax when gcc under other distros seem to think it's fine.
This is the compile rule that g77 is implementing where the error occurs:
# compile src fortran objects with fortran preprocessor
$(BDIR)/%.o: $(SOURCELOC)/src_client_main/%.FOR
$(FCOMP) $(FCFLAGS) $(VFLAGS) -c -o $@ $<
I have been implementing a Hash Table class made, and ran into a bit of a problem in my Delete function. I have the hash table made up as
vector<list<HashNode<T,X>>> m_Table
My problem is when I iterate through the vector, and then the list in that current element to try and find the Node I want to delete, the STL list class gives me the error:
Error1error C2678: binary '==' : no operator found which takes a left-hand operand of type 'HashNode<T,X>' (or there is no acceptable conversion)
Here's the Delete function:
template <typename T, typename X>

I'm getting this error in the 'my_free' function here "bp->s.size += p->s.ptr->s.size;" and "p->s.size += bp->s.size;" here.

but when i select a collumn, i recive an error because i'm selecting a cell with the mouse and i dont have code for that selection. My question is how can i put an "if" on the beguining of the event so that he can determine if it's a header or not.
I'm having a little problem with std:fstream - in my program, the user selects the location of a file which I want to remember. So, I have something like this:
Code: std::string fileLocation;
//Code here creates an 'open file' dialog box which lets the user choose which file to open.
//The string 'fileLocation' now contains the path to the chosen file.
std::ofstream prefs("prefs.txt");
if (prefs.is_open())
{
prefs << fileLocation;
prefs.close();
}
This works fine if the file chosen is in the same directory as the program, however, if they try to choose a directory outside of where the program is kept, it saves the text file into that directory instead of the same one as the program. So, it looks like outputting a directory into an ofstream actually changes the location to which the file is saved.
Is there a way to save the file directory to a text file using ofstream and still have the text file save in the same directory as the program?
