How to install wxwidgets on Eclipse Mars.2 Mac? - c++

I want to start doing some c++ but need it to be cross platform. I have found wxWidgets as a GUI solution and will use some of their SQL solutions for my program.
I tried searching the internet for how to install wxwidgets on Eclipse Mac but no luck. Haven't found anything that I can wrap my head around it.

wxWidgets is a C++ cross-platform and cross-compiler solution. It means that you don't need to install it. You can just compile it and use it to develop a software.
In order to compile this library, you should have a C/C++ compiler (clang or gcc on OSX/Mac) and their toolchain. Also if you plan to develop for OSX, you shuold have an OSX/Cocoa SDK installed (it is installed automatically with Xcode, have no idea about Eclipse).
In order to do so, you should:
Install C/C++ compiler (either with Xcode or Eclipse or any other IDE you have available).
Download latest wxWidgets release and unpack to you home diectory.
Open up a Terminal and issue following commands:
a. cd ~/wxWidgets
b. mkdir buildMac
c. cd buildMac
d. ../configure --enable-debug --with-cocoa --with-mac-osx-version-min=10.7 && make
e. ./wx-config --cxxflags
f. ./wx-config --libs
Open up Eclipse and start a new C++ project. If you are on OSX you may choose C++ bundle application.
Open the project properties and copy the results of the commands 3e and 3f to the project properties where appropriate. Consult with Eclipse manual/ML/forum to understand where to put that info.
Copy the file ~/wxWidgets/samples/minimal/minimal.cpp to you project directory and add this file to you project. Compile and run the project.
If you get stuck with any of the above instructions or get an error during compilation of either library or your project - don't hesitate to ask either here or open another thread.
Also, you can register on the wxWidgets forum at forums.wxWidets.org and subscribe to the wx-users ML.
Good luck.

GCC x64 on Windows

I tried installing CygWin64, but I cannot find any executables to build my code with in the C:\cygwin64 directory created.
I tried Win-Builds but the setup doesn't load with any mirror I give it. It tries to connect 3 times then aborts.
I tried MinGW-W64-Builds, but I cannot figure out how to install it. I can see a .sh file there, but I believe that is for Linux, so I do not know why because it says it is for Windows
Is there even a way to use 64-bit GCC on Windows? I am trying to tie it to a Code::Blocks IDE as that one only comes with the 32-bit version of MinGW.
Check out out the MinGW-w64 + GCC personal build at http://winlibs.com/.
No installation required, just unzip.
Examples on how to use are on the site, including on how to integrate with Code::Blocks IDE.

What is different of wxWidgets between when install by MSYS and compile by MinGW?

I am learning GUI programing on Windows, and I choose wxWidgets, Eclipse, MinGW for my learning. I can compile wxWidgets with command:
mingw32-make SHELL=CMD.exe -j4 -f makefile.gcc BUILD=release UNICODE=1
And I found that I can install it by MSYS by command
cd /mingw/wxWidgets-2.8.10
./configure –prefix=/mingw –disable-shared
make && make install
What must I do to integrate wxWidgets with Eclipse? Do I compile it by MinGW or install it by MSYS and How can I set up it for Eclipse Neon?
`
From your standpoint there is no difference.
It is better to compile the library with MinGW and do a DEBUG build since you will do development and a lot of times this will help a lot.
Now in order to set it up with Eclipse:
After you build is finished, open up Eclipse.
Create a project (C++) or open an existing one.
Open the dialog for project properties and find where it asks you to set the "include/header search path".
Set this to be "/include;/lib/debug/include". The second path is a path to the build_directory/include where setup.h is located.
In the same dialog for project properties find where it asks for a library search path.
There enter "main_wx_folder/lib".
Somewhere in that same page of this dialog find where it referencing the actual libraries. Add "-lwx_base... -lwx_core...". Check the actual file names inside the lib/ folder. Should be something like libwx_*.
Compile the project.
Keep in mind though that Eclipse is not "officially supported" IDE, meaning that there is no project for that IDE supplied with the library and there is not too many people use it for C++ development with wx.
The "official supported IDE" for wx are: MSVC, CodeBlocks and (to some extent) CodeLite.
It use to support Borland compiler (and IDE), but unfortunately there was a recent posts on the forum that recent version of Embarcadero broke the build of the library. This compiler is still supported though.
Good luck! If you have any issues don't hesitate to update the question with any possible errors.

Unable to build for Windows on Linux, with MinGW

Because I am not a Java enthusiast, I decided to use C++ and Qt for one of my projects. However, I came across the big cross-compiling Qt problem, and I am unable to produce an .exe file for Windows users.
My setup
Linux Ubuntu 12.04, with Wine and Qt. qmake -v gives the following output :
QMake version 2.01a
Using Qt version 4.8.1 in /usr/lib/x86_64-linux-gnu
I also have a MinGW32 compiler, which can be found at /usr/bin/i586-mingw32msvc-g++. My Wine drive_c folder contains the following Qt directories :
$HOME/.wine/drive_c/Qt/Qt5.2.0/5.2.0/Src
$HOME/.wine/drive_c/Qt/Qt5.2.0/5.2.0/mingw48_32
The mingw48_32 directory contains the necessary include/ and lib/ directories, which are used in my mkspec file, /usr/share/qt4/mkspecs/win32-x-g++/qmake.conf :
QMAKE_INCDIR_QT = /home/me/.wine/drive_c/Qt/Qt5.2.0/5.2.0/mingw48_32/include
QMAKE_LIBDIR_QT = /home/me/.wine/drive_c/Qt/Qt5.2.0/5.2.0/mingw48_32/lib
The problem
According to most guides I've found about Qt cross-compiling, my setup should be enough to run a simple :
qmake -spec win32-x-g++
make
wine /path/to/my/application.exe
But... nothing's linked. QApplication and every other symbol I use in my program are "not found". No QApplication, no QPushButton, no connect(), no SIGNAL(), no SLOT()...
My objective here is to successfully configure QtCreator to use this setup (in an independent build configuration), so that it can build a Linux executable (through the first and working configuration), and a Win32 .exe (through the MinGW setup above). However, I cannot modify a single build step in QtCreator :
Cannot add a "MinGW" toolchain : it is not available in the "Add" dropdown list.
Cannot change the -spec parameter value in the project build configurations panel. The field is non-editable.
Despite guides and solutions I found all over the Internet, my only solution so far is to send my source code to a virtual Windows machine, and have it create a new project with it. On this VM, I could probably compile for Windows... But of course, this doesn't actually sound like a real "solution" to me...
Is there any way Qt(Creator) has finally made cross-compiling easier now ? I'm getting a bit tired of "symbol not found" errors...
First,
sudo apt-get install mingw-w64
Then, check if Qt Creator finds the toolchain.
Next, until Ubuntu starts providing a mingw-w64-qt package, download the Qt source and build it. This is bound to get messy, and maybe even the simplest thing to do is to install WINE and use a Windows Qt version.

Compiling a shared library with Qt on Ubuntu 9.10

I am new to both Qt and Linux C++ development (although I have many years C and C++ development experience on Windows).
I have some legacy C projects (source files and headers - [not using Qt]) that I want to compile into shared libs on Linux.
I am proposing to store my projects under the following structure:
/home/username/Projects/project_name
/home/username/Projects/project_name/src
/home/username/Projects/project_name/build
Can anyone tell me how to do the following (using Qt to simplify the build process)
Create different build configurations (debug, release etc)
Build a configuration to create the appropriate shared library
As an aside, I have only recently installed Ubuntu 9.10 and the only C/C++ development tool I have installed (using SPM) in Qt - so I dont know if I need to install some other GNU C++ tools.
BTW I have already checked and have gcc (v4.4.1) available on my machine. I do not appear to have g++ though - I do not know whether this is significant or not.
An Ubuntu system doesn't come with build tool chain by default. Instead it has a meta package that you will need to install:
sudo apt-get install build-essential
This will install, among other the g++ compiler, although I am not sure about the Qt headers an such. For them you will need the qt4-dev package (I assume you wish to work with qt4 rather then qt3).
As for the bould structure, you will want to consult the qmake manual, or you might want to consider using CMake (apt-get install cmake) instead. CMake allow for out of build sources, as you require, and personally, I can't recommend it enough.

Eclipse Ganymede and MinGW in Windows

I'm trying to get eclipse to work with MinGW.
I've done the following:
Downloaded CDT for eclipse.
Installed MinGW.
Added C:\MinGW\bin to my path.
Opening a command prompt (CMD) and typing g++ or alike works fine.
I run eclipse, create a "New C++ Project", and only get the option saying "other toolchains".
There's a MILLION tutorials out there saying eclipse should identify MinGW on its own. It doesn't, and I don't know what to do. I've tried reinstalling everying in just about every order posible. Still no luck.
I've also noted some tutorials say something about creating a "Managed C++ Project". I've no such option, all I get is "C++ Project" and "C Project"
edit:
I have eclipse ganymede, windows x86_64, version 3.4.2
http://download.eclipse.org/eclipse/downloads/drops/R-3.4.2-200902111700/index.php
Running the "Eclipse IDE for C/C++ developers" fails, since there's no x64 version for windows. The x86 version requires x86 JAVA installed as well, and installing two versions of java, gave nothing but trouble in the past.
The instructions for setting up MinGW in Ganymede are located here.
The following are instructions and
links on how to install the current
version of MinGW. Note that these
links may become inaccurate over time
as new versions of MinGW components
are introduced. Please check the MinGW
File Release section for the latest
versions.
Download and run the MinGW setup program, MinGW-5.1.3.exe.
Select download and install the MinGW base tools and the g++ compiler.
You may select the Current or
Candidate version of these tools. You
may also install any of the other
available compilers as well.
Do not install the MinGW Make feature as the MSYS version of make
from step 5 is a more complete
implementation of make.
The MinGW setup program currently does not install the gdb
debugger. To install the debugger,
download the file from the following
location: gdb-6.6.tar.bz2
Extract the contents of the file gdb-6.6.tar.bz2 to the same location
where you installed MinGW.
If you want to use Makefile projects, download and run the setup
program from the following location:
MSYS-1.0.10.exe. MSYS provides an
implementation of make and related
command line tools. This is not
required for other types of projects
with the MinGW toolchain, which use
CDT's internal build tools to perform
the build.
Following this process resolved any problems I had.
I had the same exact problem with Eclipse Galileo and CDT 6.0.1. It turns out that CDT only recognized MinGW when it's located under c:\mingw. I had it in c:\msys\mingw so that was the problem. After I changed that everything worked fine.
The distinction between managed make projects and makefile project was removed in CDT 4.x, I think. Now there is only one type of project, but you can select different builders. CDT includes an internal builder which does not use makefiles and another one which does.
First, save yourself the effort of "reinstalling in every order possible". That is also known as trial-and-error, and will only make you more frustrated. Apply the normal problem-solving skills you have as a programmer.
Given that you have MinGW installed, what happens if you download "Eclipse IDE for C/C++ developers", start eclipse.exe, and try to create a C++-project with a MinGW toolchain?
EDIT: remember: the key in getting help with problems like these is to produce a minimal example which fails. Also, it would help if you provided URLs to the packages you installed (MinGW, Eclipse, etc.).
EDIT: I just installed CDT using the Ganymede update site, downloaded and installed MinGW from here, and restarted Eclipse, and everything worked fine. I know that doesn't help you, but it does prove that the toolchain detection isn't completely broken. Something is weird on your side.
You could try Wascana Desktop Developer. Its a distribution of Eclipse CDT configured specifically for developing on Windows.
I had the same problem (i.e. Eclipse not finding MinGW on the PATH) after I removed some of the unused files/folders from MinGW. It was ~600 MB and I was tasked to trim it down before adding to source control. I got it down to a workable ~200 MB. When I tried to re-create an Eclipse workspace afterwards, MinGW disappeared from available toolchains. It reappeared after I put the original MinGW install on the path.
