1) Preface
|
|
~~~~~~~~~~
|
|
|
|
Hi, this here is a small howto build the dietlibc target. I hope that it
|
|
will be some time no more needed because the target will be so
|
|
strateforward. Currently it is more a draft for a howto but who cares it
|
|
is more then nothing, right ? ;-)
|
|
|
|
Some pretty internal stuff is in Documentation/Developers/TODO . There
|
|
are also current problems and bugs put together so even if you are not a
|
|
developer you probably would like to read it.
|
|
|
|
The target is currently experimental like the whole 1.7 tree. So be
|
|
careful because it can kill your pet, make your mother angry, make you
|
|
sleepless or simply not work and/or compile.
|
|
|
|
2) What is dietlibc
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
Dietlibc is a small alternative libc. In contrary to glibc it is not so
|
|
bloated so it is very useful for embedded systems or installation disks
|
|
where space is very expensive.
|
|
|
|
Dietlibc is still under heavy development. There are many bugs that
|
|
shall be fixed. But it is functional enough to try build a system based
|
|
fully on dietlibc. (Someone has to start with it ;-) ) We will get this
|
|
baby running helping the dietlibc developers find bugs in their child.
|
|
;-)
|
|
|
|
3) Prepare for the build
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
You have to install dietlibc. You can use the source that is being
|
|
downloaded by rocklinux (you can find it in
|
|
download/base/dietlibc/dietlibc-$ver.tar.bz2) or get it from
|
|
http://www.fefe.de/dietlibc/
|
|
|
|
The next step is to replace the cc command with a script that runs gcc
|
|
with prepended diet wrapper. For this run this commands:
|
|
|
|
# mv /usr/bin/cc /usr/bin/cc.bak
|
|
# vi /usr/bin/cc
|
|
|
|
And insert the following code it the file:
|
|
|
|
#!/bin/sh
|
|
exec diet gcc "$@"
|
|
|
|
Then you have to change the rights for the shell script:
|
|
|
|
# chmod +x /usr/bin/cc
|
|
|
|
That is all that you need to do to start with the compile process of
|
|
dietlibc target.
|
|
|
|
4) Build
|
|
~~~~~~~~
|
|
|
|
Do the same what is described in Documentation/Build apropriatly
|
|
selecting dietlibc target in scripts/Config .
|
|
|
|
Please disable the "Create cache files after packages have been built"
|
|
option in the expert section of scripts/Config . It is not working
|
|
AFAIK.
|
|
|
|
That should be all.
