u-boot build error on SDK 1.0.2

burchmere

I follow the instructions in the Getting Started Guide for buildind u-boot, but get the following error:

make[1]: *** No rule to make target `hello_world.srec', needed by `all'. Stop.
make[1]: Leaving directory `/home/jb/OMAP35x_SDK_1.0.2/board_utilities/u-boot/examples'
make: *** [examples] Error 2

I tried "make distclean" first, then "make omap3evm_config" and "make" but got the same result. I can build u-boot from SDK 1.0.0 OK. I'll search the forum, but any ideas?

The issue here is in u-boot/examples/Makefile at line 135. The SDK 1.0.0 (which builds OK) reads...

%:: %.o $(LIB)

The SDK 1.0.2 (which fails to build with error listed above) reads...

%: %.o $(LIB) <<< note that it only has one ':' after the first '%' character.

If I add aother colon character (':') to replicate the line from the SDK 1.0.0 Makefile, then the 1.0.2 builds fine.

I'm no Makefile guy - any ideas why this is so, and why it got changed?

My understanding is that it is a make 3.81 issue, that the earlier make 3.80 did not have. It is a syntax issue. On my ubuntu 8.04 machine current version is make 3.81.

Note the following patch file that fixed the issue for me:
