Bootstrapping means to build a toolchain so that it is ready to build the rest |
| 30 |
of your system. Gentoo is a perfect operating system to perform such |
| 31 |
installation while retaining support from the software management system, |
| 32 |
Portage. |

Not only is this guide still in its early stage, it is also built on theoretical |
| 50 |
information found on the Internet and not from experience. It should be taken |
| 51 |
with a big grain of salt until the steps in it are verified and accepted by more |
| 52 |
experienced people. |

If we were to believe the stories, <e>bootstrapping</e> - the term - originates |
| 57 |
from a German legend about Baron Münchhausen who was able to save himself from |
| 58 |
drowning in a swamp by pulling himself up by his hairs. |
| 59 |
</p> |
| 60 |
|
| 61 |
<p> |
| 62 |
In computer theory, bootstrapping has several meanings. All of them boil down to |
| 63 |
building more complex systems from simple ones. This document will discuss |
| 64 |
bootstrapping a toolchain: building a full cross-compilation environment able to |
| 65 |
build software for the target system. |
| 66 |

<title>Toolchain Bootstrapping</title> |
| 72 |
<body> |
| 73 |
|
| 74 |
<p> |
| 75 |
The process of bootstrapping a toolchain is two-fold. |
| 76 |
</p> |
| 77 |
|
| 78 |
<p> |
| 79 |
At first, you use an existing toolchain to create a cross-compilation |
| 80 |
environment, a toolchain capable of running on one system but building software |
| 81 |
for a different one. The second step is to use the cross-compilation toolchain |
| 82 |
to rebuild itself so that it builds code native to the system it is booted on. |
| 83 |
</p> |
| 84 |
|
| 85 |
<p> |
| 86 |
There are three important terms we use in this definition: |
| 87 |
</p> |
| 88 |
|
| 89 |
<ul> |
| 90 |
<li>the <e>host</e> system is the system on which the programs are ran, </li> |
| 91 |
<li> |
| 92 |
the <e>build</e> system is the system on which a particular package is being |
| 93 |
built, and |
| 94 |
</li> |
| 95 |
<li> |
| 96 |
the <e>target</e> system is the system for which the software generates |
| 97 |
output (like the compiler) |
| 98 |
</li> |
| 99 |
</ul> |
| 100 |
|
| 101 |
<p> |
| 102 |
After the toolchain is bootstrapped, the third stage is to build the rest of the |
| 103 |
system using the native toolchain. |
