[U-Boot-Users] Problems with binutils 2.15

[U-Boot-Users] Problems with binutils 2.15

[Karim Yaghmour]

I've been playing around trying to get U-Boot 1.1.1 (and previous
versions) to build with the following toolchain:
- binutils 2.15
- gcc 3.3.2
- glibc 2.3.2

This toolchain was built for a PPC target with no particular CPU
flags or CPU patches. Here's what I'm doing:
$ cd u-boot-1.1.1
$ make TQM860L_config
$ make CROSS_COMPILE=powerpc-linux-

Now, this starts to build and goes far enough, but somehow LD
actually seg faults somewhere down the line. I've copied the
command line that fails in Make directly to the command line and
I get this (the output is somewhat edited for the form, but it's
all there):
----------------------------------------------------------------------

Segmentation fault

If run from the makefile, this would come right after:

...

a - virtex2.o
a - xilinx.o
a - circbuf.o
make[1]: Leaving directory `/home/.../u-boot-1.1.1/common'
----------------------------------------------------------------------

I've tried 0.4.0 and 1.0.0 and get very similar behavior.

Anyone see this before?

glibc does not matter here; U-Boot is  self-contained  and  does  not
need any glibc stuff.

I haven't seen any reports  (neither  positive  nor  negative)  about
binutils 2.15 yet. With 2.14 it works fine here.

Best regards,

I know. I just thought I'd mention the entire list for completness.

OK. It's good to know 2.14 works. I'll give it a try.

I use 2.14.90.7 and have got the same problem. IMHO it's an LD bug which
appears in very special case: if you request the map (-Map option) and
the link command file (u-boot.lds in this case) contains a conditional
statement (. = DEFINED(env_offset) ? env_offset : .;), the link fails
with segmentation fault. Remove -Map as a workaround and the link should
succeed. I found this some time ago but have not got time to fix the LD.
