Programming :: SDL + Eclipse + CDT Compiling But Not Linking With G++ On Arch?
Jan 22, 2011
I have set up Eclipse + CDT on an Arch 2010.05 install. I set up an eclipse project and added SDL as a dependency (see below):
Project -> Properties
* -> GCC C++ Compiler -> Preprocessor -> main=SDL_main
* -> GCC C++ Linker -> Libraries -> SDLmain SDL (in that order top to bottom)
* -> GCC C++ Linker -> Libraries -> Library Search Path -> /usr/lib/ (I verified that libSDL.a and libSDLmain.a are there)
This is the code I'm compiling. It's designed to just be a hello world style SDL app to see that everything is working.

compiling and linking using gcc: What does a file name with a suffix '.a' represent? If I have multiple .c and .h files, how can I link them together? How can I create the .a file?

I have 3 c++ files, classdef.h (header file with class definition), methods.cpp (class methods) and program.cpp - the program itself. Both .cpp files have
Code:
#include "classdef.h"
in files. How I can link the files together and compile them in one executable program? I am using Geany IDE for coding.

I have written an OpenGL based program which uses i.a. libjpeg that I want to link statically so I can send it to someone who doesn't have all the libraries needed installed to allow for a dynamically linked executable to run. As such I tried with giving the [b]-static[b] parameter to gcc.
Code:
x86_1$ make
gcc -O3 -c jpegloader.c
gcc --std=c99 -O3 -c --std=c99 -I/usr/include -L/usr/X11R6/lib main.c
[code].....
Why would gcc claim that I'm missing GLUT? This works perfectly fine when I do dynamic linking -- i.e. omitting the -static argument.

I have written a PCI LKM device driver that compiles and loads correctly via #insmod libfoo.ko. When # dmesg | less is run I get good results and no errors in the log. The LKM header file is visible in the eclipse workspace.how do I attach (link) this loaded LKM in a eclipse project so that the LKM driver functions are visable?

Basically, I'm trying to compile program A, which depends on LibA and LibB. LibA would not build with my version of G++ 4.4.3 due to a bug, so I've compiled the latest G++ 4.5 (installed in /opt directory) and built that library successfully (also installed in /opt).
I have LibB on my system already, but it was built with the 4.4.3 version. When compiling my final program, am I going to have issues because the .so files were built with different versions of gcc/g++? Or should I just rebuild a special version of LibB with the later version of the compiler just for that program? I can proceed and just see what happens, but I'm a little confused about how things work in a situation like this.

I am new to Slackware and I am wondering how you set the ARCH variable. On the multilib wiki page it says:
"Rather than editing the script and change/remove CFLAGS definitions, you can set the ARCH to 'x86_64' and save yourself some time."
So from this I understand that they advise against editing the Slackbuild script. How do I set the ARCH variable on the command line or is it a configuration file I need to edit? I am running Slackware 13.1 64.

I have been writing PHP using Adobe Dreamweaver; I have been looking around for an application that focus more in PHP.I have found:

and:

I know Zend stands behind PHP and that Eclipse is a popular open source IDE. What is the difference tho?Is the PDT Project only a functionality that could be added to Eclipse IDE? Is Zend for Eclipse a stand alone IDE for PHP? if so, Why the Eclipse in the name? I have downloaded Zend Studio for Eclipse, so far it seems very complete (no that have learned how to use all its features).

The Metrics plug-in supports Java development well at Eclipse.

I would like to know if it supports Eclipse CDT, so I can use it with my C++ project. Any thought? If it doesn't support CDT, is there any good static code analysis tools available for Eclipse CDT?

I get an error while compiling in Eclipse:
*.o: file not recognized: File truncated
I tried to remove all the .obj and .moc folders and make clean but can't solve the problem! Maybe I'm missing something here.

This is probably a really stupid thing to ask considering the development I'm doing (effectivly creating a virus scanner), but how do I link classes/cpp files?I have 3 applications/sections that I can compile/combine with a makefile, that's fine, but I need them to run 1, 2, 3 once the output from the makefile is done.Currently the only section to actually run is whichever I have "main" in and obviously if I put that into all three, they won't compile as one.I've been looking all over the place at all sorts, header files and such, but there is no mention of how toually do this although I'm sure it must be possible. I'm used to being able to do this in Java and I'm sure I've seen C++ applications do it, but not worked out how.I have 3x .cpp files which are combined into one using a makefile:
Code:
# Virus Scanner
scanner.out : ProgramList.o MD5Hash.o HazardCheck.o

There's a problem with static linking (and no problems with dynamic linking).
Here's my code:

And makefile rule:

That's dynamic linking. And it works perfectly. If i use static linking
Quote:
There is an undefined reference error:
Quote:
As nm shows there's a symbol named BuzzerInit in static library.

I have a really simple program trying to use XInput2.h, which fails on linking
Code:
#include <X11/extensions/XInput2.h>
int main(){
Display *XSession = XOpenDisplay(NULL);
int OriginScreen = 0;
int pID = 7;
[Code]....
I'm at a loss about what to do. Replacing XIWarpPointer by XWarpPointer and removing the pID argument solves it, but is not an option (no input ID).

I am trying to add some function to the c++ project (calling function) and the called function are in C. And i am getting error "undefined reference to "Hello(int,int)" " while linking. It is compiling correctly. It is linking to header file mention in the calling function. This header file has definition to the c - called function. Do you thinking having c files into C++ project will be a problem? Should I remove <stdio.h> in c files?

I have a question about shared objects and when mapping and linking is established in the following code...Well more of a verification.
getsetx.c - shared object source code Code: unsigned long x = 0;
unsigned long getx(void)
{
return x;
}
[Code].....
Now its my understanding when I execute ./testit, getsetx.so will get mapped into its address space at start up and testit will link any functions as they are needed..

I tried to link my executable program with 2 static libraries using g++. The 2 static libraries have the same function name. I'm expecting a "multiple definition" linking error from the linker, but I did not received.
Code:
//staticLibA.h
#ifndef _STATIC_LIBA_HEADER
#define _STATIC_LIBA_HEADER
int hello(void);

I just did the pacman -Syu command today since i have had limited access to internet i could use with arch lately, (been tethering via droid which is only compatible in ubuntu) The command line works fine, i even reinstalled X to see if that was the problem,whenever i do startx it loads up for a second but before my xfce screen even pops up the screen blinks and blackens.

Just what it says in the title.
I can work in a 32-bit VirtualBox VM, but it's very inconvenient and I would rather work in my 64-bit desktop if that's not too difficult.
These are all the lib32 packages I have installed code...

I would like to ask you something about open-source and linux. Is it possible to make a commercial application for linux and sell it compiling it with linking to open-source libraries without altering them and consequently without allowing download of the source code and without making the application itself free?

I am using Centos 5.4 with gcc v4.1.2. If I take a bunch of .o files and I then link with my main.o to form an executable then this links and executes just fine. If however, I try to create an archive file (.a) using 'ar rus xxx.o yyy.o etc' and then try to link the resulting .a with my main.o then I get 'undefined symbol' linker errors and I don't understand why.

The issue I am currently facing is more of an annoyance / curiosity, and it may not even be a problem, but it sure feels like one. Background: I am becoming a computational chemist (grad school begins in the fall) and the code I run is all in fortran. I am currently compiling with gfortran. When I compile the code (on a box running ubuntu server), everything appears to compile fine, but the linking stage is taking five to ten minutes. I ran the time command while making it and got the following results.
Quote:
time make
gfortran -c -O3 -fomit-frame-pointer -finline-functions -ffast-math suijtab.f
Linking testCompile ...
done
[code]...
I just don't understand why it is taking 5 minutes of real time if it only takes 10 - 15 sec of system time?

I have created a simple test class - Mortgage, with the class declaration in the .h file and the class's methods defined in the .cpp file. (mortgage.h && mortgage.cpp, respectively) Straight up C++ 101 as far as I can tell. I instantiate the class in the main() function, which is defined in practice.cpp. Using Geany on Ubuntu, both the practice.o and mortgage.o files are created, but then I get a linker error: undefined reference to class::functionName
I get it for each function. If the mortgage.cpp file is foremost in the editor when I click "build", then I get the undefined reference to main() error, if practice.cpp is foremost (where the main() function is) then I get undefined reference to Mortgage::Mortgage(), and all the rest of the functions defined for that class. How do I get the linker to know where my object files are so it will link them in? Or is the problem somewhere else entirely?

So I decided to take my first steps into programming with C + gtk. So far I have doneI loaded eclipse and ensured I had the cdt package Created a new C/C++ project called "play" Added a new source file called "Playfullsrc.c" Added the following to paths and symbols (output of the command: pkg-config --cflags gtk+-2.0)
Code:
/usr/include/gtk-2.0
/usr/lib/gtk-2.0/include
/usr/include/atk-1.0
/usr/include/cairo
/usr/include/pango-1.0
/usr/include/pixman-1
/usr/include/freetype2

Code:
/home/knox/workspace/HW/src/projectBuilder.xml:5: the file attribute is required
here is my file at this point after many variations
Code:

It works fine if I leave out the Main-Class line in manifest but then the jar is not executable Dick
