Code Blocks is an excellent programming option for C. It consists of an open source, multiplatform integrated development environment that supports using multiple compilers, among which are: GCC (MingW / GNU GCC), MSVC, Digital Mars, Borland C 5.5 and Open Watcom. In this video I explain how to install Code::Blocks and the C compiler on the Mac (Note: there are 3 files to download in order to be able to compile!). Double-click on the Code::Blocks icon. The first time you do this, the Mac OS will ask, “Are you sure you want to open it?” Select Don’t Warn Me When Opening Applications on This Disk Image and click Open. Code::Blocks should start and find the gcc compiler installed with the Command Line Tools. Select the gcc compiler, as shown in the.

These are instructions on how to build Code::Blocks under Apple Mac OS X.They have been tested under Mac OS X version 10.4 (PowerPC and Intel),and should work similarly on the newer Mac OS X 10.5 and 10.6 as well.

We will be building everything from scratch using the source code, andnot use any available package managers likeMacPorts,Fink,Gentoo orRPM.Packaging can be done later, once it has reached a more stable release.

Update: building for MacPorts can be found at the end of the document.

Install Developer Tools

If they didn't come bundled with Mac OS X, get the Xcode Tools (or Developer Tools for older Mac OS X) from http://developer.apple.com/tools/ or from your install disk.

This will install Apple versions of:

• http://www.gnu.org/software/gcc/ (GNU Compilers)
• http://www.gnu.org/software/gdb/ (GNU Debugger)
• http://www.gnu.org/software/make/ (GNU Make)

Apple regularly pulls all older links in order to promote newer Mac OS X, but all theold developer tools can be downloaded from ADC at http://connect.apple.com/

You need a (free) developer registration with Apple first, in order to log in there.For Mac OS X 10.4, you want (at least) Xcode 2.2, since earlier versions were buggy.

Check Autotools versions

Depending on your OS version, you might need to download and compile new versions of these:

• http://www.gnu.org/software/autoconf/ (GNU Autoconf)
• http://www.gnu.org/software/automake/ (GNU Automake)
• http://www.gnu.org/software/libtool/ (GNU Libtool)

Check what you have, with --version (note that GNU libtool is called 'glibtool' on Mac OS X)

Currently Code::Blocks requires versions:

• autoconf 2.50+
• automake 1.7+ (1.9+ needed in order to build the dist tarball)
• libtool 1.4+ (1.5.8+ highly recommended to get some bug fixes)

Automake example

For Mac OS X 10.4, you will only need an upgraded (local) installation of automake 1.9.x.

You can download 'automake-1.9.6.tar.gz' and configure and install it with something like:

Code Blocks Pour Mac Os Hd

Since it's now known as 'automake-1.9', it won't interfere with the regular 'automake'

If you would rather have the new version to be called when calling 'automake', let it install into /usr/local and put /usr/local/bin before /usr/bin in your PATH.

Libtool example

Download libtool source. The following instructions will overwrite your current version of libtool with the one you just downloaded.

Note that this will replace the system version of glibtool, which might have some compatibility issues with building other software.

FYI: Universal Binaries

If you are building for Mac OS X 10.4 or later, you might want to build 'Universal Binaries 'These are binaries that contain code for both PowerPC ('ppc' arch) and Intel ('i386' arch)

The basic flags that needs to be added are:

(You only need the sysroot parameter on PowerPC Macintosh, not on a Intel Macintosh)The '-arch i386 -arch ppc' is what tells the compiler to build a 'universal' (or 'fat') binary.

Usually it's easiest to build one version for 'powerpc-apple-darwin8',and one version for 'i686-apple-darwin8', and then merge them with 'lipo'

Some caveats:

• pre-compiled headers might fail with a 'no main' error. If they do, add a -c to only compile them
• when cross-compiling, tools like auto_revision might fail to build. copy these from a native build
• the Tiger compilers might crash from time to time, but that is only to be expected (it seems)...

See Technical Note TN2137: Building Universal Binaries from 'configure'-based Open Source Projects

FYI: Compilers

When building for older versions of the SDK, you want to make sure to use the same compiler.

Mac OS X 10.6 has GCC 4.2 as the default compiler, which won't work for the Mac OS X 10.4 SDK.

FYI: ANSI or UNICODE

For the moment we are using 'ANSI' (--disable-unicode, default) for Mac OS X 10.3 and earlier,and 'UNICODE' (--enable-unicode, optional) for Mac OS X 10.4 and later.

See http://www.wxwidgets.org/manuals/stable/wx_unicode.html#unicodeandansi

FYI: 32-bit or 64-bit

Code::Blocks currently uses wxMac (wxOSX/Carbon), which is 32-bit only. So it's not possible to build for 'x86_64'.

When Code::Blocks (and requirements) has been updated to use wxOSX/Cocoa, then a 64-bit version might be built too.

Build wxWidgets

Download the source code

Download the tarball for the wxMac release:

Apply necessary patches

Don't forget to apply any released patches!

Configure and (GNU) Make

note: the easiest way to build a Universal Binary with wxWidgets isthe new flag: --enable-universal_binary (you need wxWidgets 2.6.4+)

Install into Destination

Bundle library for Mac

To avoid having the Code::Blocks user having to compile or install wxWidgets themselves,we can bundle it with our application so that it is contained in the application bundle.This could also be done by statically linking wxWidgets, but with dynamic linking we canshare the wxWidgets library between all applications using wxWidgets (not just Code::Blocks)

Way One: Library (dynamic)

To bundle our shared library with the application, we include it in 'MacOS' and change the path:

@executable_path will be replaced with e.g. /Developer/Applications/CodeBlocks.app/Contents/MacOS

Way Two: Framework (bundle)

To bundle our framework with the application, we include it in 'Frameworks' and change the path:

This way it will first look in the framework path (-F), and then in for the shared library path (-L) as usual.

Install Subversion client

On Mac OS X 10.4, you need to install the Subversion (svn) program:

Note: you need SVN for the Code::Blocks revision scripts to work!

Build CodeBlocks from SVN

Download the source code

Apply necessary patches

For a list of all available patches, see:

You might need to convert line endings from DOS to Unix first.

Bootstrap with Autotools

You need to use the newer version of automake (see above), for the 'bootstrap'. (OS X 10.5 users may have recent enough autotools so they may not need to install them)

Mono Fix

If you have the Mono.framework installed, then it probably set up a symlink like:

Unless you have a 'proper' pkg-config installation the Code::Blocks configure will fail, so move this symbolic link aside.

Configure

Note: the easiest way to build a Universal Binary for Code::Blocks is to build once for PowerPC (-arch ppc) and once for Intel (-arch i386), and then merge them (with lipo) afterwards.

Note: You need to patch the location of the pre-compiled headers, or it will generate them in the same place for both arch.

Tiger Fix

There is a bug in the glibtool of Mac OS X 10.4, that fails to link C++ libs:

To work around this, you need to edit the generated 'libtool' script manually:

This bug has been fixed in GNU libtool 1.5.8 and later.

(GNU) Make

'nice' isn't strictly needed, it just makes the compile run at a lower process priority

For the Universal Binary build:

Install into Destination

'sudo' asks you for an admin password, in order to get install permissions

For the Universal Binary build:

Where 'lipomerge' is a custom shell script:

Bundle application for Mac

After building codeblocks in the regular Unix way, you need to bundle it with the iconsand various other info that it needs to make a regular stand-alone Macintosh application.

There are two ways of accomplishing this, old Mac OS-style resource or NeXT-style bundle.The old resources are handy while developing, while bundles are more suitable for release.

Note: You need to use either of these methods, or your application will launchin the background behind all other windows and will be unable to receive any events!

Way One: Mac OS (resource)

Handy while developing, as you don't need to create a whole bundle.

First we install the program to the PREFIX directory of your choice:

Note: on the Intel Macintoshes, the icon comes up as 'broken'(apparently it assumes that all apps with resforks are Classic)

Start the application with a small prefix shell wrapper like this:

You don't need the 'DYLD_LIBRARY_PATH' stuff,if you are installing to a system directory.

Common PREFIX Settings

Local: PREFIX=/usr/local

System: PREFIX=/usr

MacPorts: PREFIX=/opt/local

Fink: PREFIX=/sw

Way Two: NeXT (bundle)

This does not involve resources, and is more relocatable.

Files needed:

• codeblocks.plist (generated, rename to 'Info.plist')
• codeblocks.sh (shell wrapper, rename to 'CodeBlocks')

• app.icns (icons are available in src/src/resources/icons)

The MacOS program will just be a shell wrapper that calls 'bin/codeblocks', like above.Traditionally the bundle would include Frameworks and Resources, but we'll just avoid thosehere and use the regular 'lib' and 'share/codeblocks' instead (just as with a regular install). These temporary directories are listed in italic below, they're not really used in bundles...

Setup a hierarchy like this, and copy the files from the regular build/install and the above file list to it:

The CodeBlocks application can now be moved with the Finder, and started up like a regular Mac application. (the nightly build includes a more advanced Info.plist and more icons - for also mapping all the files that the application can open, like source code and header files and such)

Proper Application Bundling

To avoid the shell wrapper, the binary can now be moved from 'bin/codeblocks' to 'MacOS/CodeBlocks'. Helper files are moved from 'share/codeblocks' to 'Resources'. The dynamic libraries are moved from 'lib' to 'MacOS':

To avoid having to use a DYLD_LIBRARY_PATH, we rename the shared libraries (with the install_name_tool program) from e.g. /usr/local/lib/ to @executable_path/:

The libraries can have their names changed using the -id parameter:

You also need to change all of the loadable bundles for the plugins:

You can check the result, what libraries/frameworks it links to, with:

Optionally you can then repeat the process, for the wx library too...

Here is a full script to do the job... It assumes to be executed at the same directory level as the CodeBlockSVN.app directory that will receive all the stuff... maybe enhanced but it is a first try that do work when packaging an OS X SVN build.

FYI: Darwin vs. Mac OS X

'Darwin is the UNIX technology-based foundation of Mac OS X.'

'Pure Darwin' here refers to the Open Source version of the OS:

• http://puredarwin.org/ or http://gnu-darwin.sourceforge.net/

(that is: Darwin using X11 instead of Aqua for the user interface)

Install with MacPorts

Install wxWidgets

You will need the wxWidgets library, install as port with:

If you want the X11/GTK version on Mac OS X, instead use:

Install Code::Blocks

After that is installed, you can install Code::Blocks with:

If you want the X11/GTK version on Mac OS X, instead use:

This will download the SVN trunk, and any dependencies:

Note: to upgrade from SVN, you need to uninstall first:

This is both because all SVN versions are numbered '0',but also due to a bug in the Code::Blocks build scripts.

Running +aqua (wxMac) version

After the build completes, you can start the program by:

Note that the wxMac application bundle in 'MacPorts'is just a wrapper, with symbolic links to /opt/local...

Running +x11 (wxGTK) version

The non-bundled wxGTK version is instead started with:

When running X11/wxGTK programs in Mac OS X, you can use'open-x11' to first start up X11.app and set up $DISPLAY:

Code::Blocks is a free, open-sourcecross-platformIDE that supports multiple compilers including GCC, Clang and Visual C++. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins.Currently, Code::Blocks is oriented towards C, C++, and Fortran. It has a custom build system and optional Make support.

Code Blocks Pour Mac Os 10.10

Code::Blocks is being developed for Windows and Linux and has been ported to FreeBSD,^[2]OpenBSD^[3] and Solaris.^[4] The latest binary provided for macOS version is 13.12 released on 2013/12/26 (compatible with Mac OS X 10.6 and later), but more recent versions can be compiled and MacPorts supplies version 17.12.

History[edit]

After releasing two release candidate versions, 1.0rc1 on July 25, 2005 and 1.0rc2 on October 25, 2005, instead of making a final release, the project developers started adding many new features, with the final release being repeatedly postponed. Instead, there were nightly builds of the latest SVN version made available on a daily basis.^{[citation needed]}

The first stable release was on February 28, 2008, with the version number changed to 8.02. The versioning scheme was changed to that of Ubuntu, with the major and minor number representing the year and month of the release. Version 20.03 is the latest stable release; however for the most up-to-date version the user can download the relatively stable nightly build or download the source code from SVN.

In April 2020, a critical software vulnerability was found in the Code::Blocks IDE, identified by CVE-2020-10814.^[5][6]

Jennic Limited distributes a version of Code::Blocks customized to work with its microcontrollers.^[7]

Features[edit]

Compilers[edit]

Code::Blocks supports multiple compilers, including GCC, MinGW, Digital Mars, Microsoft Visual C++, Borland C++, LLVM Clang, Watcom, LCC and the Intel C++ compiler. Although the IDE was designed for the C++ language, there is some support for other languages, including Fortran and D. A plug-in system is included to support other programming languages.

Code editor[edit]

The IDE features syntax highlighting and code folding (through its Scintilla editor component), C++ code completion, class browser, a hex editor and many other utilities. Opened files are organized into tabs. The code editor supports font and font size selection and personalized syntax highlighting colours.

Debugger[edit]

The Code::Blocks debugger has full breakpoint support. It also allows the user to debug their program by having access to the local function symbol and argument display, user-defined watches, call stack, disassembly, custom memory dump, thread switching, CPU registers and GNU Debugger Interface.

GUI designer[edit]

As of version 13.12 Code::Blocks comes with a GUI designer called wxSmith. It is a derivative port of wxWidgets version 2.9.4.^[8] To make a complete wxWidgets application, the appropriate wxWidgets SDK must be installed.

User migration[edit]

Some of Code::Blocks features are targeted at users migrating from other IDE's - these include Dev-C++, Microsoft Visual C++ project import (MSVC 7 & 10), and Dev-C++ Devpak support.

Project files and build system[edit]

Code::Blocks uses a custom build system, which stores its information in XML-based project files. It can optionally use external makefiles, which simplifies interfacing with projects using the GNU or qmake build systems.
