I am running ubuntu and have tried adding -1GL to the end of my gcc compiling commands but the error says "unrecognized commandline option: 1GL". do i have to install any packages to get this to work?
Its supposed to be an l not a 1.
I am trying to refresh my memory here as I did some studies many years ago but the results elude me.Also todays c/c++ compilers may have better optimizations.Say I have a static library that includes three obj modules.Each of these object modules has a number of functions. These functions do not reference any other functions within the obj module.My main app links this library but only references one function from each of the object modules.
Question: Are the complete contents of each module linked into my main app or are todays linkers smart enough to just link the functions used?
I have a libcx3d.a which contains my VrmlParser class and other classes which are used by VrmlParser. I have a main.cpp which does this :
VrmlParser vp = new VrmlParser();
double **VOB = vp.getVOB();
When I compile using g++ main.cpp -o main -L. -lcx3d, I get the following errors :
'VrmlParser' was not declared in this scope.
expected ';' before vp.
'vp' was not declared in this scope.
There is a header file called "VrmlParser.h" in the static library. Should I include this header file in main.cpp ? If so, will include "VrmlParser.h" work ? I have the .a and .cpp in the same directory. I can't find the header file for the static library.
I have built a static library that contains a macro. From a separate exe, I am calling this macro, but it doesn't work.
The compilation of the static library and that of the exe went okay.
Static lib contains just the macro definition.
Exe contains call to this macro.
Is there anything else that I need to do for this to work?
I have written a program that uses boost in visual studio 2012. The only boost library I used is filesystem by doing.
1)Properties->Linker->General and adding the path or the .lib to the additional dependencies. The libraries, link at compile time.However when i move the exe to a different computer, it doesn't work. Therefore the libraries were dynamically not statically linked. So my question is how do I statically link the filesystem library, so that i can include boost/filesystem.hpp in visual studio 2012?
I am trying to use the C++ version of VOCE voice recognition API. It is an API built in Java, with support to C++ as well.
It works totally fine when I am working with VC2010. In vc2010 I have put all the necessary include files in the Vc++ Directories->Include Directories, and the library D:Program FilesJavajdk1.7.0_45lib in Linker->Additional Library Directories, and i added jvm.lib in Linker->input And everything works great

I am trying to build an application that has one static library dependency, however I am getting this error when linking:
1>ClCompile:
1> All outputs are up-to-date.
1>LINK : fatal error LNK1104: cannot open file 'TestWrapperLib.obj'
Why I might be getting that? I have the .lib in the depends line, and the directory where it is at in the include line.
I am trying to add in a few 3rd party libraries to an existing project solution. I have no source code or knowledge on how the libraries were built (i.e. what run-time library was used). I have recieved the following errors and warnings:
1>CAPS_LIB.lib(PCEfunc.obj) : MSIL .netmodule or module compiled with /GL found; restarting link with /LTCG; add /LTCG to the link command line to improve linker performance
1>libcmt.lib(getenv.obj) : error LNK2005: _getenv_s already defined in MSVCRT.lib(MSVCR90.dll) ***There are multiple of these errors
1>LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of other libs; use /NODEFAULTLIB:library

1>C:Program Files (x86)BCI 2000 v3progRelWithDebInfo..CAPSVRInterface.exe : fatal error LNK1120: 1 unresolved externals
CAPS_LIB.lib is one of the libraries I am trying to add in and it seems to be the one causing the problem. I believe I have added in all three libraries into the project solution correctly, but I can't seem to find a solution to these errors.
I search for a really simple window library with a OpenGL context. I really only want to create window, I don't want a GUI library like wxWidgets. The best would be, if the library is cross platform compatible. In Google I only find very big libraries with widgets and other stuff.

I write a program which now works perfectly well. However, I want to make it run at the right time automatically, instead of waiting for a user to start it when needed.
The basic problem is, that in a WinPE environment an exe is running. Unfortunately it would need critical input, which must be inputted perfectly. So, I wrote a program which gets the data and sends it to the other app, by bringing it to the front and presses the keys needed using SendInput().
However, this program should wait for it's cue, then get on the inputting part. It's cue should be the point where the program waits for the first user input with this displayed on the last line:
Text:
My question is: how to listen and check whether the last line displayed is "Text:"?
I've tried with AttachConsole(), but for some reason it opens a new console window. I checked and the PID I'm using is the console window's, so I don't know why that happens.
The few lines I'm trying with:
HWND hwnd = FindWindow(NULL, "Administrator: Command Prompt");
SetForegroundWindow(hwnd);
SetFocus(hwnd);
DWORD process_id;
GetWindowThreadProcessId(hwnd, &process_id);
[Code] ...
Please don't criticize the first line. I know it can be ambiguous, but I modified it, When actually using it, the exe name will be in the title, so it will be unique.
I am using visual studio 2010 c++ express for C/C++ programming but is novice here to take command line arguments..i did went to project->properties->debugging and specified there the command line arguments but it didnt work..i think i need to know the format to enter the arguments.

I'm trying to read in a file specified in the command line but I'm having some trouble. The command line entry specifies the inputfile preceded by '<' and the output file preceded by '>' like so
./program -v < input_file.cmd > output_file.cmd
This is what I've got so far.
int main(int argc,char* argv[]){
string strv="-v";
string input="<";
string output=">";
string str;
string input_file;
const char* in=input_file.c_str();

This compiles ok, but when i run it using :
./program -v < test1.cmd
I get a segfault, if i cout argc it returns '2' where i would expect for this command line entry, I 'd get 4.
I'm not yet outputting to file, just to the screen so im not specifying an output file yet.
I am writing a c++ program in Linux.. I am reading a line from commandline at run time using "getline(std::cin,str);". now, what i want is if i left the commandline as idle (terminal as idle), then i want to know that the commandline is empty... is it possible ???

When you write and compile a program, on the right side (the "output" side), you can read this command line arguments:
$ g++ main.cpp -o demo -lm -pthread -lgmpxx -lreadline 2>&1
What is the meaning of the following arguments? -lm [link the math header file, right?]
-pthread
-lgmpxx
-lreadline
Any book (ebook, tutorial, printed book, whatever) where I can find all (absolutely all) these and other possible arguments?
I'm currently working on making a program that is run through a GUI run through the command line. The program basically takes an app file and a boot file and runs it through a bunch of functions and generates a new outfile. Anyway I'm new to C and can't figure out how to code it so I can type the two file paths into the command line and read them into the function. Is it possible to do this within the "if else" statement?
Code:
int main(int argc, char *argv[]){
const char * const SrcFilePath;
const char * const SRecordPath;
const char * const FopIspFilePath;

I tried the exercise 5 on page 312 of King's Book C programming A modern approach second edition. Write a program named sum.c that adds up its command line arguments which are assumed to be integers . Running the program by typing :
sum 8 24 62 should produce the following input
Total : 94
Use the atoi function to convert each command line argument from string form to integer form
My solution is :
Code:
#include<stdio.h>
#include<stdlib.h>
int main(int argc , char *argv[])
{
int i , sum=0;
}

It is running good without problems but I am wondering because it is very small solution with few lines of code.
I want to see how the command line arguments work. However I don't know how to enter this input. show me a method to see if my code works?
View 9 Replies View RelatedI have to make a c++ program, in which with an algorithm I have to code a text from a file and write it to another file. The input should like this: "code forCoding.txt toBeWritten.txt" ; or like this: "decode toBeReadFor.txt toBeWrittenIn". I have done everything except one thig: It is says I have to be able to input parameter.
How should i write this? I read [URL] ....., but still dont get. The input of my program has to have 3 strings, so I guess argc should be 3, but I dont really get it. What should I have in my main about this parsing command line parameters?
I am not sure how to enter command line arguments when I run the executable of the file below. I want check an make sure that only two arguments get into the main() before running the rest of the code. I'm using bash on linux.

I know you go the the debugger and pass them in. I just need to know the syntax. I know &(ProjectDir) goes first because the text file is in the project directory but how do I pass the text file in as well. The file's name is "tester.txt".
View 2 Replies View RelatedI know this works as expected if your command line arguments are strings.
#include <stdio.h>
int main( int argc, char *argv[] ) {
printf("Program name %s

if( argc == 2 ) {

Would you be able to do something similar to this if you have integers or would you need to use the first method then convert it with atoi?
#include <stdio.h>
int main( int argc, int *argv[] ) {
printf("Program name %s
", argv[0]);
if( argc == 2 ) {

I have "hello world" set for command line args.

Why would it do that.
In the following program I have one input .txt file of random words.

When I run the program with command line arguments:
program.exe FILEINPUT.TXT FILEOUTPUT.TXT
I get the output same as input.
