Doing a ./MAKEALL ARMV7 (gcc [1]) with the recent git head I get a lot of

arm-none-linux-gnueabi-ld: section .bss [...] overlaps section .rel.dyn [...]
arm-none-linux-gnueabi-ld: section .dynsym [...] overlaps section .bss [...]
...
make: *** [u-boot] Error 1

for various boards [2]. I wasn't able to track this down to specific commit, yet.

Anybody with an idea?

Best regards

Anybody with an idea?

Weird... Linker file says explicitly that .bss does overlay above .rel.dyn, so the first message should not ever happen. As for the second, it could happen depending on the bss, .re.dyn and .dynsym sizes, maybe.

I'll have a look today.

I've tried ./MAKEALL efikamx with ELDK32, and did not see any warning nn either u-boot/master (ce5207e191c59b3135303fd03b98dd2ac3701ba2) or u-boot-arm/master (8305f7e98b5f7b9b6070777e68f3fe1871b9cd92).

Can you check your setup for locally modified/added files and let me know which exact commit ID you're building in (git rev-parse HEAD) and which ARM repo it is from?

Can you double-check your toolchain and host OS?

2009q1 shows the issue, but 2010q1 does not, nor does 2011q although it gives the following warning:

arm-none-eabi-ld: warning:
/opt/arm-2011q1/bin/../lib/gcc/arm-none-eabi/4.5.2/libgcc.a(_bswapsi2.o) uses variable-size enums yet the output is to use 32-bit enums; use of enum values across objects may fail

As for the overlap issue: I see no significant difference in the map files generated by 2009q1 and by 2010q1. I wonder if this could be a change in the default state of the --check-sections option of ld?
