Hi all,
I`ve implemented Gaisler Research`s Leon3 SPARC core to a FPGA evaluation board of Actel. Now I`m about to get U-Boot running. So I made up my own board directory, added header files with my configuration-parameters etc. just as discribed in the u-boot README.
The "make myboard_config" goes well, but "make all" fails with the following message.
make[1]: *** No rule to make target `/u-boot-2009.08_build/cpu/leon3/start.S', needed by `/u-boot-2009.08_build/cpu/leon3/start.o'. Stop.
I?d like to add that I set "BUILD_DIR=`/u-boot-2009.08_build" and I am using Gaisler`s Bare Cross Compiler with GCC 3.4.4. Searching the mailing-list-archives brought no advice to me. I also tried to study the Makefiles for half a week now, but I?m not familiar enought with it.
Thanks for your help!
Best regards,
Tobias Kraitschy

Hi! Read carefullly your config file!
I've working with same things (Gaisler+Leon3+Gcc-4.3.3) on board
ML-402. My config compiles without problem, so i suggest that makefile
is good.

The source has a cpu/leon3/start.S file. The Makefile in that directory has
$(START): $(START:.o=.S)
so that is where the dependency is coming from. Is the file's location
correct? Does the file really exist there:
ls /u-boot-2009.08_build/cpu/leon3/start.S

Setting BUILD_DIR to be an absolute path (leading "/") seems odd.
<http://www.denx.de/wiki/DULG/UBootConfiguration> says...
"By default the build is performed locally and the objects are saved in
the source directory. One of the two methods can be used to change this
behaviour and build U-Boot to some external directory:"
Try building it in the source directory rather than putting the output
in a separate directory. There are perennial problems with building
into a separate directory (e.g. the $(OBJ) prefix is not prepended to
the destination). This is an easy thing to miss or mess up (also easy
to fix). Since leon3 is not a heavily used target, I would suspect that
is the problem.
I would suggest not using BUILD_DIR and see if it works. If it does,
update the cpu/leon3/Makefile to look like a more heavily used target
CPU, e.g. a PowerPC like the 83xx:

Hi,
Unsetting BUILD_DIR solved the problem.
Of course /u-boot-2009.08_build/cpu/leon3/start.S does not exist here. I?ll try to figure out what?s wrong in the Makefile.
Thanks.
Best regards,
Tobias Kraitschy
