SELF: compile of util-linux

[James Don]

Hi,

I am just browsing through the SELF code ... and trying for kicks to make
"my own version" as an exercise to learn more about packages required for a
running embedded Linux system ...

So far I have ...

1.) Built uclibc
2.) Built busybox with uclibc gcc wrappers
3.) Built insmod with uclibc gcc wrappers

I am reading the compile of util-linux (see below item 1) ... I am
relatively new to linux so I have some questions (most of which are probably
stupid seeing as just started looking at this)...

1.) The "patch" part of the compile ... is it to add kernel support for what
I am compiling? If I managed to get a pre-built image to run on an unpatched
kernel what am I missing?

2.) When you run the "sed -e 's/XXX-powerpc-linux-/$(CROSS_PREFIX)/" I
assume this should go into the make sysyem and put the cross compiler in the
build ? ... sorry never used "sed" just skimmed the man page

3.) For kicks I have taken the tar ball I downloaded of util-linux (version
2.11y) and tried to compile it with the uclibc gcc wrappers (see item 2
below) ... now this does when I get to the "make part" ... it seems to die
because "configure" was not called ... but its not called from SELF's make
file either ??? If I call make from the util-linux directory it calls
configure ... but then uses my local 'cc' ...

Any tips would be great ;-) In the mean time I will keep digging and
hopefully see what's wrong with my script ;-)

Best regards,
Jim
