[U-Boot-Users] Compile error: option `-g' is ambiguous
I just pulled the latest tree and tried building for MPC8349EMDS, I got this:

Unfortunately, I wasn't paying much attention to the recent -g discussion, but it looks like whatever changes were made breaks the 8349EMDS.
I think that your version of gas doesn't support the -g option without specifing the debugging info format.

I'm running 2.15. The latest is 2.17. The changelog for 2.16 says this:
* Add a -g command line option to generate debug information in the target's preferred debug format.
I don't think U-Boot should require gas 2.16 or higher. Is this going to be a requirement? Updating our toolset is a real pain, and I'd rather fix the Makefile instead.

We all agre that we don't want to require only the latest and greatest toolchains. I still couldn't make up my mind what the best way to fix the problem is. Please allow me for a little thinking...

Sure. But in the meantime, can you tell me where the -g option is specified? I'm looking through all the Makefiles and the git log, and I just can't find it.

Resp. his version of GCC driver does not pass the correct options to as.

powerpc-unknown-linux-gnu-gcc -Wa,-g -D__ASSEMBLY__ -g -Os -fPIC -ffixed-r14 -meabi -D__KERNEL__ -DTEXT_BASE=0xFE000000 -I/temp/u-boot.i2c/include -fno-builtin -ffreestanding -nostdinc -isystem
It seems a problem with the -Wa,-g

I'll do Thanks
