    I have the exact same issue when I tried building the toolchain.
    Can someone help with this issue ?

    Cheers

    I edit the Makefile and remove insight on the line:
    toolchain: test-components cross-toolchain insight

    Thanks henrys.
    Got past the error by removing call to 'insight' target from 'toolchain' top target as you suggested.
    Do you know what are the consequences of removing 'insight' ?
    I will probably find out soon enogh but just asking in case you have faced any issue with this workaround....

    I got another the error that follows
    /bin/sh: line 1: no: command not found
    make[4]: *** [fr.gmo] Error 127
    This error was due to a path variable in a makefile not getting a valid value for location of msgfmt

    This error can be solved by opening the file
    /LinuxTools/crosstool/build/m68k-linux/gcc-3.4.3-glibc-2.3.5/gdb-6.3/opcodes/po/Make-in

    And replacing the following lines
    #GMSGFMT = PATH=../src:$$PATH @GMSGFMT@
    #MSGFMT = @MSGFMT@

    with lines
    GMSGFMT = /usr/bin/msgfmt
    MSGFMT = /usr/bin/msgfmt

    Insight is just the debugger like GDB.

    /home/henry/BSP/LinuxTools/insight-6.3.50/bfd/elf32-m68k.c: In function ''elf_m68k_check_relocs'':

    i had the same thing, it's gcc4.1's stricter aliasing rules... i fixed the warning by changing the offending line to cast via a void*:



    {
    asection *s;
    void* vp;

    s = (bfd_section_from_r_symndx
    (abfd, &elf_m68k_hash_table (info)->sym_sec,
    sec, r_symndx));
    if (s == NULL)
    return FALSE;

    vp = &elf_section_data (s)->local_dynrel;
    head = (struct elf_m68k_pcrel_relocs_copied **) vp;
    }

    Alternatively, you can turn off strict aliasing by setting CFLAGS in your environment:
    CFLAGS = "-fno-strict-aliasing -g -O2"
