Hi Dirk,

What's the status of the linker errors across tool chain versions seen by building the 'omap3_evm' board?
This was already discussed in the threads [1] and [2], but it seems to me that there was no acceptable fix, yet?
E.g. with CodeSourcery's tool chain 2009q1-203 I get
arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e33f] overlaps section .rel.dyn [8003f5e0 -> 80044e6f] arm-none-linux-gnueabi-ld: section .dynsym [80044e70 -> 80044f0f] overlaps section .bss [8003f5e0 -> 8007e33f] arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 overlaps previous sections
What we learned from [2] is that using [3] fixes the build (at least for me with the tool chain mentioned above). I.e. converting omap3_evm_version from u8 to int
-static u8 omap3_evm_version; +static int omap3_evm_version;
makes the issue disappear.
But if I understood the discussion correctly, this is no acceptable fix and can be used only as debug help (?).
Any further hints?
Three comments at least:
- I personally would agree with the change to int, but since Wolfgang
considers it a workaround to the linker issue, I won't accept it either.
- IIRC, the linker emits a warning, not an error. We can live some
time with a warning if it is documented and it is being worked on.
With 2009q1-203 it's an error and 'omap3_evm' isn't built:
arm-none-linux-gnueabi-ld: section .bss [8003f5e0 -> 8007e33f] overlaps section .rel.dyn [8003f5e0 -> 80044e6f]
arm-none-linux-gnueabi-ld: section .dynsym [80044e70 -> 80044f0f] overlaps section .bss [8003f5e0 -> 8007e33f]
arm-none-linux-gnueabi-ld: u-boot: section .bss vma 0x8003f5e0 overlaps previous sections make: *** [u-boot] Error 1
size: './u-boot': No such file
Thanks

- I did offer to try and find a minimal test case (one .c file, one
.lds file, one simple command line) to cause the warning and submit it to the binutils list, but haven't had time so far.
Thanks
Dirk
Amicalement,
