I haven't gotten anything on the crossgcc list, so I'm going to cross-post this here. FYI, the toolchain is gcc-3.3 / newlib-1.11.0.

Thanks for any advice you can give me.

Subject: alloc problem?

Our arm-elf project here has been plagued with problems when trying to use
sprintf. We've gotten by without it by writing some of our own conversion
functions, but ideally we'd be able to use c++, which would need use alloc a
lot. My instinct tells me that alloc is the problem, because the problems we've
had with sprintf are fairly unpredictable and it's the only function that we're
using that needs an alloc. Furthermore, I suspect that the root of the problem
may be our linker script (because the wierd behavior of sprintf has seemed to
variy with program size at times), but I know little about linker scripts, and
nothing about what the alloc functions require of one.


Here's our linker script:

SEARCH_DIR("/usr/local/src/arm-elf-gcc-combined/installs-combined/arm-elf/lib");

SECTIONS
{
    . = 0x00008000;
    ER_RO : { *(ER_RO) }
    .text : { *(.text ) }
    .rodata : { *(.rodata) }
    .data : { *(.data) }
    __bss_start__ = .;
    .bss : { *(.bss) }
/*    __sbss_start = .; */
    /*__sbss_end = .; */
    __bss_end__ = .;
    . += 0x4000;

PROVIDE (__stack = .);
    _end = .;
    end = .;
