[ECOS] configtool bug

[ECOS] configtool bug

[Jürgen Lambrecht]

Hello,

I  cannot find this bug back on 
http://bugs.ecos.sourceware.org/query.cgi?product=eCos, and actually, if 
this problem is documented, it would be no real bug, but I could not 
find any documentation about it.
If this is a new problem, should I enter a bug report, or update the 
configtool documentation?
Here's the bug:

When programming, I often keep backups in the same directory, for 
example of the hal_platform_setup.h file, and I call those backups e.g. 
hal_platform_setup.1-01-02_2a.h.
But then the configtool also copies those backup files to the build tree 
(e.g. in BUILDx_install/include/cyg/hal/) and inserts them in the 
makefile (e.g. in BUILDx_build/hal/arm/at91/std_ims/current/makefile).
The compilation does not give errors, but the binary (of course) does 
not run.
This is the relavant part of the wrong makefile:

Why not?  Those files will never be referenced in any of the eCos
code, so the fact that they get sloshed around by the makefile should
be totally irrelevant.  If your program isn't running, you need to
figure out why.

Why should the binary not run? These backup header files are not used.

What you are probably seeing is the broken dependancies on vector.S
meaning that install/lib/vector.o is not recompiled when you edit
hal_platform_setup.h. This is a known bug and should be in bugzilla
somewhere.
