Rtems Rebuild Remake Question

[Bill Butler]

Ha!.. you just thought I went away!

Well I tried what you guys suggest and it works real neat except for one
thing.. it does not work! (disclaimer: for me)

I'm sure the BSP I'm using is not updated so  I need some help of where
to look to fix it or someway to convert a Makefile.in to a Makefile for
now. 

Here is what I'm doing.

I have built 2 BSP for the m68k one I modified from Fiddles (sbc5307)
and one from RTEMS (mcf5206elite). 

Specific problem is once I modify the Makefile.am file and run bootstrap
it DOES create the Makefile.in file. I run "../configure ..." and then
"make all" but neither the configure or the make copies over the updated
makefile to the build directories.

Here is a simple example. Note: I'm under cygwin so the directory
structure is a little different that suggested in Docs.


>>/opt/tools/rtems-ss-20020215/c/src/lib/libbsp/m68k/mcf5206elite/start

$ touch Makefile.am

$ ls -l  (makefile.am newer than makefile.in)

$ ../../../../../../bootstrap

$ ls -l (makefile.in newer than makefile.am which is newer than Makefile
in build directory)

$cd  /opt/tools/build

>> /opt/tools/build

$ ../rtems-ss-20020215/configure --target=m68k-rtems --enable
rtemsbsp="mcf5206elite sbc5307" --prefix=/opt/m68k_rtems

$cd
/opt/tools/build/m68k-rtems/c/mcf5206elite/lib/libbsp/m68k/mcf5206elite/
start

>>/opt/tools/build/m68k-rtems/c/mcf5206elite/lib/libbsp/m68k/mcf5206elit
e/start

$ls -l (same old Makefile)

$cd  /opt/tools/build

$ make all

$cd
/opt/tools/build/m68k-rtems/c/mcf5206elite/lib/libbsp/m68k/mcf5206elite/
start

$ ls -l (same old makefile)...


$format c: (good thing this is cygwin)


I guess my question is what tells configure to copy files over when they
are out of date or missing? I'm guessing it something I configure in the
BSP directory so I will go nose around there.

Thanks for you help.

Try adding --enable-maintainer-mode to your configure-options, then all
this is supposed to happen automatically.
Eg. if having edited your <BSP>/Makefile.am (Adding/deleting files)
cd build/<...>/<BSP>
make
will rebuild Makefile.in etc.

[There exist some broken BSPs where this doesn't work.]

Furthermore, it is sufficient to run bootstrap from the directory which
contains the configure.ac/in which is responsibile for the file you have
edited.
Eg. 
[Editing [...]/<BSP>/driver/Makefile.am
cd [...]/<BSP>
<rtems-rootdir>/bootstrap

Try adding --enable-maintainer-mode. 

Then in most cases, running "make" is sufficient. If it doesn't work,
(General exceptions are BSPs containing "tools" - A known general bug in
RTEMS configury - and adding directories - A known general limitation of
the auto*tools), running bootstrap from the directory with the
configure.ac related to the edited Makefile.am should be safe.
