I'm trying to compile my project, but is not working, the weird thing is if i put all the code in 1 file it compile, but not in a project, source code:
I want to use two separate files in 1 program, but cannot get it to work. I don't know if it's my files or the compiling thats wrong. I have never used 2 files in my programs so far. Only used #include <stdio.h>.
Here are my files: extern_static.c Code: extern int i; int main(void) {
I've a problem compiling my makefile. The additional files are enclosed.
the error I get: $make ./main gcc -ggdb main.c /tmp/ccPIxwjP.o: In function `main': /home/ilan/Embedded_linux/Lesson-2-Makefiles/lesson-2.1/main.c:6: undefined reference to `func1' /home/ilan/Embedded_linux/Lesson-2-Makefiles/lesson-2.1/main.c:7: undefined reference to `func2' collect2: error: ld returned 1 exit status make: *** [main.o] Error 1 $
Code: my make file: main : main.o file1.o file2.o gcc -ggdb main.o file1.o file2.o -o gdb-main main.o : main.c file1.h file2.h
Code: /* Demonstrates using the gets() return value. */ #include <stdio.h> /* Declare a character array to hold input, and a pointer. */ char input[257], *ptr;
[Code]....
I just got this from the book that I am using and it is for testing for input of a blank line and readers are being warned in using this format (line 18):
Code: while ( (*ptr = gets(input)) != NULL)
What is the correct syntax if a gcc compiler is to be used?
I'm trying to compile a library for use with PoLabs Pokeys 56U USB device (PoKeys56U) on Linux Mint 17 64-bit.
I'm using the information from here - New cross-platform library for all PoKeys devices - MyPokeys
When I run
sudo make -f Makefile.noqmake install
I get the following errors;In file included from PoKeysLibCore.c:22:0:
PoKeysLib.h:38:28: error: conflicting types for "int64_t" typedef long long int64_t; ^ In file included from /usr/include/stdlib.h:314:0, from PoKeysLibCore.c:21:
When I try to compile a program from a C book I am following I am getting these errors, I have looked for ways to resolve it but I wasn't able to.

Every time I try to compile this, I get the error message, "error: no matching function for call to" on lines 18, 45, and 46. Basically every time I try to call on the function sales and printStock. I don't know what the message means or why I get it.
#include <iostream> #include <fstream> #define N 10 using namespace std;
I'm a beginner with C and wonder how to include single header files (*.h) in to my project. I mean header files which are not included to the standard installation package.
I thought it would work if I just copy the newheader.h file in to library folder c:MinGWinclude, but it didn't work. Is there some kinf of GCC -command or procedure to add these single header files or how it should work?
All of those standard header files are working well and I don't have any problems with them.
if I include iostream twice in my project why is that valid? Wouldn't the linker see that there are two definitions of it and report a error, but it works?
I'm trying to convert dicom .dcm file to .jpeg using Imebra in C++ app using QT Creator as dev environment.
I've downloaded Imebra and was able to run QT project example for Dicom2Jpeg conversion successfully. But when I tried to copy same code to my C++ app it failed to run with following error msg:
malloc: * error for object xxxxxx: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug
I have followed steps on adding Imebra files to my project as it was shown on Imebra site. Also used their qt project as example. My main.cpp open dicom file, then loads it to dataset, then calls my dialog window. It crashes on loading dataset.
#include "QApplication.h" #include "QHBoxLayout.h" #include "mydialog.h" #include "iostream.h" include "library/imebra/include/imebra.h" int main( int argc, char ** argv ){
[Code] ....
Deeper debugging showed that source of error is in JpegCodec.cpp file readStream() function when checking JpegSignature to see if it's in wrong format with resulting internal PUNTOEXE error "detected a wrong format".
Interesting thing is that while running same test dcm file using given dicom2jpeg example (which has exact same code of opening file and loading it) gives no errors and converts to jpeg successfully. So I know it's not the file issue, but the way imebra code is integrated into my C++ app.
My dev environment: macbook pro with Lion OS, QT Creator, QT project, C++ code, ITK library added, Imebra files are completely integrated as part of the Qt project.
So, my question is how do I work/link/reference/call Imebra functionality in QT project? Am I forgetting to link something, or some object is not instantiated/deleted on time?
I have this image/video compression project that is to be done in C. I've been given this source code by my supervisor which is supposed to be a working one.
Assuming I have a sequence of 5 images in .pgm format (image41.pgm, image42.pgm .... image45.pgm). Some of the code involved is
When I tried to compile the code using make file (shell script), I got this error message "In function 'readPgm' format '%d' expects argument of type 'int *', but argument 3 has type 'unsigned char *' "
Can identify what the problem is and how to rectify it?
I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)
I'm trying to print a single linked list backward with functions/classes. I have created the main file and 3 header files. But I'm getting an error on one of the header files, linkedListIterator after adding #include "linkedListType.h". It says that "linkedLlistType.h" is calling itself. And when I try to run it, I get an error of "too many header files." I have tried changing the headers many times, but nothing seems to work.
.cpp file:
/*(Printing a single linked list backward) Include the functions reversePrint and recursiveReversePrint, as discussed in this chapter, in the class linkedListType. Also, write a program function to print a (single) linked list backward. (Use either the class unorderedLinkedList or the class orderedLinkedList to test your function.)*/
I'm using multiple C++ files in one project for the first time. Both have need to include a protected (#ifndef) header file. However, when I do that, I get a multiple definition error.
From what I found from research, adding the word inline before the function fixes the error. Is this the right way to do this, and why does it work? Should I make a habbit of just declaring any function that might be used in two .cpp files as inline?
I'm taking an intro to c++ class and during an exercise I ran into multiple errors that are out of my knowledge to fix. The rest of the class is using Visual and that is all the instructor knows so i'm in my own figuring out Xcode. Basically I wrote the same program twice but one has a different struct and I get all sorts of errors with it. understand what the errors are and why they occurred.
The working program is this:
#include <iostream> #include <fstream> #include <iomanip> #include <cmath> using namespace std; struct point { public: double x1,y1; double x2,y2;
[code]....
This program does not compile and I get the following errors:
stl_iterator_base_types.h
1) Symantic Issue No type named 'value_type' in 'myPoint' 2) Symantic Issue No type named 'iterator_category in 'myPoint' 3) Symantic Issue No type named 'difference_type' in 'myPoint' 4) Symantic Issue No type named 'pointer' in 'myPoint' 5) Symantic Issue No type named 'reference' in 'myPoint'
I'm compiling some open source code (originally written for Linux / gcc) which uses the following line to determine if a particular section is being compiled for an x86 processor:-
