<h1 align="center">Building egcs-1.0</h1>
|
|
|
|
<p>Now that egcs is configured, you are ready to build the compiler and
|
|
runtime libraries.
|
|
|
|
<p>We <b>highly</b> recommend that egcs be built using gnu-make; other
|
|
versions make work, then again they might not. To be safe build with gnu-make.
|
|
|
|
<p><b>Building a native compiler</b>
|
|
<p>For a native build issue the command "make bootstrap". This will build
|
|
the entire egcs compiler system, which includes the following steps:
|
|
|
|
<ul>
|
|
<li> Build host tools necessary to build the compiler such as texinfo, bison,
|
|
gperf.<p>
|
|
|
|
<li> Build target tools for use by the compiler such as gas, gld, and
|
|
binutils.<p>
|
|
|
|
<li> Perform a 3-stage bootstrap of the compiler.<p>
|
|
|
|
<li> Perform a comparison test of the stage2 and stage3 compilers.<p>
|
|
|
|
<li> Build runtime libraries using the stage3 compiler from the previous
|
|
step.<p>
|
|
</ul>
|
|
|
|
<p>If you are short on disk space you might consider "make bootstrap-lean"
|
|
instead. This is identical to "make bootstrap" except that object files
|
|
from the stage1 and stage2 of the 3-stage bootstrap of the compiler are
|
|
deleted as soon as they are no longer needed.
|
|
|
|
<p><b>Building a cross compiler</b>
|
|
|
|
<p> We recommend reading the
|
|
<a href="ftp://ftp.cygnus.com/pub/embedded/crossgcc/FAQ-0.8.1">
|
|
crossgcc FAQ</a> for information about building cross compilers.
|
|
|
|
<p>For a cross build, issue the command "make cross", which performs the
|
|
following steps:
|
|
<ul>
|
|
<li> Build host tools necessary to build the compiler such as texinfo, bison,
|
|
gperf.<p>
|
|
|
|
<li> Build target tools for use by the compiler such as gas, gld, and
|
|
binutils.<p>
|
|
|
|
<li> Build the compiler (single stage only).<p>
|
|
|
|
<li> Build runtime libraries using the compiler from the previous
|
|
step.<p>
|
|
</ul>
|
|
|
|
<p>Note that if an error occurs in any step the make process will exit.
