Building egcs-1.0
|
|
|
|
Now that egcs is configured, you are ready to build the compiler and
|
|
runtime libraries.
|
|
|
|
We highly recommend that egcs be built using gnu-make; other
|
|
versions make work, then again they might not. To be safe build with gnu-make.
|
|
|
|
Building a native compiler
|
|
For a native build issue the command "make bootstrap". This will build
|
|
the entire egcs compiler system, which includes the following steps:
|
|
|
|
|
|
Build host tools necessary to build the compiler such as texinfo, bison,
|
|
gperf.
|
|
|
|
Build target tools for use by the compiler such as gas, gld, and binutils.
|
|
|
|
Perform a 3-stage bootstrap of the compiler.
|
|
|
|
Perform a comparison test of the stage2 and stage3 compilers.
|
|
|
|
Build runtime libraries using the stage3 compiler from the previous step.
|
|
|
|
|
|
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.
|
|
|
|
Building a cross compiler
|
|
|
|
We recommend reading the crossgcc FAQ for information about building
|
|
cross compilers.
|
|
"ftp://ftp.cygnus.com/pub/embedded/crossgcc/FAQ-0.8.1"
|
|
|
|
For a cross build, issue the command "make cross", which performs the
|
|
following steps:
|
|
|
|
Build host tools necessary to build the compiler such as texinfo, bison,
|
|
gperf.
|
|
|
|
Build target tools for use by the compiler such as gas, gld, and binutils.
|
|
|
|
Build the compiler (single stage only).
|
|
|
|
Build runtime libraries using the compiler from the previous step.
|
|
|
|
|
|
Note that if an error occurs in any step the make process will exit.
