<h2>Before you begin</h2>
|
|
|
11 |
|
|
|
12 |
<p>Depending on how you obtained the CDT, you might have also received
|
|
|
13 |
a toolchain with a built-in CDT integration.
|
|
|
14 |
However, if you downloaded the CDT from an update site, then you will require a toolchain before
|
|
|
15 |
you can build and debug any projects.</p>
|
|
|
16 |
|
|
|
17 |
<p>The base CDT supports integration with the GNU toolchain.
|
|
|
18 |
This includes GNU's make, gcc compiler, and gdb debugger utilities.
|
|
|
19 |
If you require a toolchain to build software for your development host, this
|
|
|
20 |
is the best choice to get started.
|
|
|
21 |
|
|
|
22 |
<p>Each platform that runs the CDT requires different steps to acquire this toolchain.</p>
|
|
|
23 |
|
|
|
24 |
<h3>Linux</h3>
|
|
|
25 |
<p>All Linux distributions include the GNU toolchain. They may not, however, be installed by default.
|
|
|
26 |
For instructions about installing the GNU toolchain for Linux, see the instructions for your particular distribution.</p>
|
|
|
27 |
|
|
|
28 |
<h3>Windows</h3>
|
|
|
29 |
<p>For windows, MinGW, and Cygwin are the two main choices for acquiring the GNU toolchain:</p>
|
|
|
30 |
<ul>
|
|
|
31 |
<li><a href="http://www.cygwin.com"><b>Cygwin</b></a> is a port of the Linux environment to Windows.
|
|
|
32 |
It provides a compatibility layer in a set of DLLs. These DLLs are
|
|
|
33 |
<a href="http://www.gnu.org/copyleft/gpl.html">GPL licensed</a>,
|
|
|
34 |
making any code that links to them also subject to the GPL.
|
|
|
35 |
Cygwin, however, does provide the fullest implementation of the GNU toolchain
|
|
|
36 |
by supporting the GNU libc C runtime library.
|
|
|
37 |
Note: currently Cygwin >= version 3.4.4-999 is not supported since gcc and g++ commands cannot
|
|
|
38 |
be launched from the windows' native shell.
|
|
|
39 |
<p> <br></p>
|
|
|
40 |
</li>
|
|
|
41 |
<li><p><a href="http://www.mingw.org"><b>MinGW</b></a> is a port of the GNU toolchain to the Windows platform.
|
|
|
42 |
The biggest difference over Cygwin is that MinGW uses the Windows C runtime libraries (mscvrt) instead
|
|
|
43 |
of GNU's libc. As a result, a compatibility layer is not required, thus avoiding the GPL issues
|
|
|
44 |
with Cygwin. There are differences, though, between the Windows and GNU C runtime libraries that will make
|
|
|
45 |
writing portable applications more difficult.</p>
|
|
|
46 |
<br>
|
|
|
47 |
<p>However, MinGW provides the best integration support with the CDT
|
|
|
48 |
due to it's direct support for the Windows environment.</p>
|
|
|
49 |
<br>
|
|
|
50 |
<p>The following are instructions and links on how to install the current version
|
|
|
51 |
of MinGW. Note that these links may become inaccurate over time as new versions of
|
|
|
52 |
MinGW components are introduced. Please check the
|
|
|
53 |
<a href="http://sourceforge.net/project/showfiles.php?group_id=2435">
|
|
|
54 |
MinGW File Release</a> section for the latest versions.</p>
|
|
|
55 |
<br>
|
|
|
56 |
<ol>
|
|
|
57 |
<li>Download and run the MinGW setup program,
|
|
|
58 |
<a href="http://downloads.sourceforge.net/mingw/MinGW-5.1.3.exe">MinGW-5.1.3.exe</a>.
|
|
|
59 |
<li>Select download and install the MinGW base tools and the g++ compiler.
|
|
|
60 |
You may select the Current or Candidate version of these tools.
|
|
|
61 |
You may also install any of the other available compilers as well.
|
|
|
62 |
<p><b>Do not install the MinGW Make feature</b> as the MSYS version of make from step 5
|
|
|
63 |
is a more complete implementation of make.</p></li>
|
|
|
64 |
<li>The MinGW setup program currently does not install the gdb debugger.
|
|
|
65 |
To install the debugger, download the file from the following location:
|
|
|
66 |
<a href="http://downloads.sourceforge.net/mingw/gdb-6.6.tar.bz2">gdb-6.6.tar.bz2</a>
|
|
|
67 |
<li>Extract the contents of the file gdb-6.6.tar.bz2 to the same location where you installed MinGW.</li>
|
|
|
68 |
<li>If you want to use Makefile projects, download and run the setup program from the following location:
|
|
|
69 |
<a href="http://downloads.sourceforge.net/mingw/MSYS-1.0.10.exe">MSYS-1.0.10.exe</a>.
|
|
|
70 |
MSYS provides an implementation of make and related command line tools.
|
|
|
71 |
This is not required for other types of projects with the MinGW toolchain,
|
|
|
72 |
which use CDT's internal build tools to perform the build.</li>
|
|
|
73 |
</ol>
|
|
|
74 |
</ul>
|
|
|
75 |
<br>
|
|
|
76 |
<h3>Other Platforms</h3>
|
|
|
77 |
<p>The GNU toolchain is supported on all platforms that the CDT supports. For instructions about installing the GNU toolchain
|
|
|
78 |
on your platform, see your platform vendor.</p>
