How to setup GTK+ to develop with Code::Blocks on Ubuntu Linux

How to setup GTK+ to develop with Code::Blocks on Ubuntu Linux - c++

I am trying to develop a GTK+ application on Ubuntu 11.4, using Code::Blocks.
www.gtk.org has instructions on building GTK+ from source, that looked complicated. But the Ubuntu package manager listed libgtk3-dev as a package that I installed.
Code::Blocks I installed using the Ubuntu Software Center.
Using the Code::Blocks project wizard to create a GTK+ project, when I build, the project fails to compile "cannot find gtk/gtk.h".
Clearly the GTK include (and lib) folders are not added to the Code::Blocks search folders. I have located the relevant paths and files...
Do I have to explicitly & manually add all the search paths to Code::Blocks' search paths? Or am I missing some installation step.

Assuming that you have located and installed the correct package. As of 2011, the current package was libgtk-3-dev then the pkg-config tool can be used to extract the linker and compiler flags - and with proper escaping in the Code:Blocks settings can inject the correct settings automatically.
Open Code::Blocks Settings > Compiler and Linker Settings... and add the following under Global Compiler Settings > Compiler Settings > Other Options
`pkg-config --cflags gtk+-3.0`
and add this to Global Compiler Settings > Linker Settings > Other Options
`pkg-config --libs gtk+-3.0`
With the ` this has the effect of running the pkg-config tool calling --cflags gtk+-3.0 (or --libs) which, assuming libgtk3-dev is installed, injects the necessary search folders and lib directives onto the gcc command line.
As an alternative, developer.ubuntu.com lists Anjuta as a C/C++ IDE that can create GTK+ projects. As an alternative to Code::Blocks its far more polished as an Ubuntu IDE.
Scratch that. Anjuta looses its sheen quickly.

exe file won't run on other devices [duplicate]

I have been working on a project (a game to be specific) and I feel that I should start over with different libraries. So when doing this I reinstalled Code::Blocks and setup my new libraries and includes.
But as of now Im having a problem starting u[ my new project to test if all of the includes work. This problem is: libstdc++-6.dll was not found. At first i wondered if I could just find this file online, but its nowhere to be found(or at least the many places I have searched...) Soon after, I tried loading up my old project, and the same problem happened again(wierd... ._.) I was thinking its maybe my compiler, so I used my older compiler and it did the same thing! At this moment I held the problem off for tomorrow(which is today)
So my question is: If anyone else had this problem, how would you solve it?
Im using Code::Blocks with MinGW as the compiler on Windows Vista 32 bit.
*****EDIT*****
Here are the Build options in my project. Note that these are the settings in the Project, not the global compiler:
In (project name)->Compiler settings->Otehr options:
(I use // to seperate the commands)
-mthreads//
-fmessage-length=0//
-fexceptions//
-fident//
In (project name)->Compiler settings->#define:
WIN32//
_WINDOWS//
In (project name)->Linker settings->Other linker options:
-static-libstdc++//
-static-libgcc//
-Wl,--enable-auto-image-base//
-Wl,--add-stdcall-alias//
-Wl,--enable-auto-import//
In linker->link libraries i have various links to files with a .a extension, these files include Bullet PHysics, Ogre3D, and SFML
In the search directories i have links to the MinGW/bin, and the MinGW/lib directories, along with other links to different libraries.
My Compiler is MinGW, a GNU GCC compiler for windows 32 bit. and the IDE is Codeblocks. Also note that in Debug and Release settings on the project, there is nothing.
Most of these setings are also pieces that i got from the Ogre3D Application setup tutorial if that is of any help.

If you are using MingW to compile C++ code on Windows, you may like to add the options -static-libgcc and -static-libstdc++ to link the C and C++ standard libraries statically and thus remove the need to carry around any separate copies of those. Version management of libraries is a pain in Windows, so I've found this approach the quickest and cleanest solution to creating Windows binaries.

As far as I know, this is the C++ Runtime Library. So it depends on the compiler you use to create your program (A new version will include some C++0x stuff, an older version will probably not for instance. It depends of the compiler and of its version).
If you use MinGW then you should use the libstdc++-6.dll found into the folder of this compiler. MinGW/bin folder should be the place to search for it on your computer.
If you copy this file in the same directory as your executable, it should be OK.

Simply removing libstdc++-6.dll.a \ libstdc++.dll.a from the mingw directory fixes this.
I tried using the flag -static-libstdc++ but this did not work for me.
I found the solution in: http://ghc.haskell.org/trac/ghc/ticket/4468#

This error also occurred when I compiled with MinGW using gcc with the following options:
-lstdc++ -lm, rather than g++
I did not notice these options, and added: -static-libgcc -static-libstdc++
I still got the error, and finally realized I was using gcc, and changed the compiler to g++ and removed -stdc++ and -lm, and everything linked fine.
(I was using LINK.c rather than LINK.cpp... use make -pn | less to see what everything does!)
I don't know why the previous author was using gcc with -stdc++. I don't see any reason not to use g++ which will link with stdc++ automatically... and as far as I know, provide other benefits (it is the c++ compiler after all).

useful to windows users who use eclipse for c/c++ but run *.exe file and get an error: "missing libstdc++6.dll"
4 ways to solve it
Eclipse ->"Project" -> "Properties" -> "C/C++ Build" -> "Settings" -> "Tool Settings" -> "MinGW C++ Linker" -> "Misscellaneous" -> "Linker flags" (add '-static' to it)
Add '{{the path where your MinGW was installed}}/bin' to current user environment variable - "Path" in Windows, then reboot eclipse, and finally recompile.
Add '{{the path where your MinGW was installed}}/bin' to Windows environment variable - "Path", then reboot eclipse, and finally recompile.
Copy the file "libstdc++-6.dll" to the path where the *.exe file is running, then rerun. (this is not a good way)
Note: the file "libstdc++-6.dll" is in the folder '{{the path where your MinGW was installed}}/bin'

I use Eclipse under Fedora 20 with MinGW for cross compile.
Use these settings and the program won't ask for libstdc++-6.dll any more.

I just had this issue.. I just added the MinGW\bin directory to the path environment variable, and it solved the issue.

I placed the libstdc++-6.dll file in the same folder where exe file is generated.

You only need to add your "mingw-install-directory"/bin/ to your Path in your System environment variables ... that's it !!

I had same problem. i fixed it. i was using Codeblocks and i save my .cpp file on desktop instead of saving it in Codeblocks file where MinGW is located. So i copied all dll files from MinGW>>bin folder to where my .cpp file was saved.

You can also copy the dll files in the directory of your exe file

I had this problem too. I was compiling in command prompt and used the flag -static.
My command before:
"g++ test.cpp -o test.exe"
and afterwards:
"g++ test.cpp -o test.exe -static"

I had the same problem and I solved it by running the compiled exe as an administrator.

Integrating wxWidgets into Existing XCode Project

There are many tutorials about setting up a new XCode project for use with wxWidgets, but I need to integrate it with a large existing XCode C++ project.
The wxWidgets setup process is unclear to me. I built wxWidgets in XCode with the included wxcocoa.xcodeproj file. But when I include all the header files and the libwx_osx_cocoa.dylib library to my existing XCode project, I get all these errors within the wxWidgets header files like Use of undeclared identifier 'wxApp' and No matching constructor for initialization of 'wxEvent' as if it's missing files, but I've included all the header files and compiled library. I tried building wxWidgets in the terminal and get the same errors. I tried make install to actually install wxWidgets on my system. I tried running this command wx-config --cxxflags --libs all in the terminal. I tried adding wx-config --cxxflags and wx-config --libs all to the compiler and linker flags in my XCode project. None of these had any effect.
The irony is that I'm trying to use wxWidgets library to make the GUI process easier, but instead I've spent two days pulling my hair out trying to get my C++ XCode project to compile. Does anyone know what I'm doing wrong?
EDIT: The problem seems to be XCode. I've downloaded the wxWidgets Hello World sample program at the bottom of this page. I can build this program without issue in the terminal, but when I put it into a new XCode project, it won't build. How can I get XCode to build this simple program?
cx-config output:
XCode project settings:
EDIT 2: I exported the Build Log out of XCode and saw that the actual build command uses clang. When I successfully compile Hello World in the terminal, I use clang++. When I try the same command with clang, it doesn't work. Perhaps this is the issue, since clang only links C libraries and the errors XCode is giving me relate to not being able to find standard C++ functions.
EDIT 3: Wow I hate XCode. I got my Hello World program to compile by accident. The solution was putting the wxWidgets compiler flags in the Targets Build Settings, whereas before, I had it in the Project Build Settings. I assumed the Targets would inherit the Project settings, but I guess not!
EDIT 4: I got my complicated XCode project to compile with the wxWidgets libraries by taking all the search paths & flags and moving them from the Project Build Settings to the Targets Build Settings. What a nightmare! Glad it's over

#WaddleDee72
,
I suggest doing following:
Delete wxWidgets directory.
Unpack wxWidgets into i.e. ~/wxWidgets.
Open Terminal.
In the Terminal
4a. cd ~/wxWidgets
4b. mkdir buildOSX
4c. cd buildOSX
4d. ../configure --enable-debug
4e. make -j5
After successful build
wx-config --cxxflags
wx-config --libs
Use the output of 2 commands above and put the values where they belong in XCode project.
If you get any issues - let us know.
Thank you.
