--- Comment #4 from Anastasius Focht <focht at gmx.net> ---
Hello Mega,

the app works as expected.

It seems you don't understand the limitations of the app.

--- snip ---
Error: ElfBinaryFile :: GetMachine: Unsupported machine type: 40 (0x28)
--- snip ---

This is output from the app, not Wine.

You are trying to decompile binaries for the ARM architecture which the app
doesn't support. Look at the source code of the app if in doubt.

$ svn checkout https://svn.code.sf.net/p/boomerang/code/trunk boomerang-code

boomerang-code/boomerang/loader/ElfBinaryFile.cpp:852

--- snip ---
...
MACHINE ElfBinaryFile::GetMachine() const
{
    int machine = elfRead2(&((Elf32_Ehdr*) m_pImage)->e_machine);
    if ((machine == EM_SPARC) || (machine == EM_SPARC32PLUS)) return
MACHINE_SPARC;
    else if (machine == EM_386) return MACHINE_PENTIUM;
    else if (machine == EM_PA_RISC) return MACHINE_HPRISC;
    else if (machine == EM_68K) return MACHINE_PALM; // Unlikely
    else if (machine == EM_PPC) return MACHINE_PPC;
    else if (machine == EM_ST20) return MACHINE_ST20;
    else if (machine == EM_MIPS) return MACHINE_MIPS;
    else if (machine == EM_X86_64)
        {
            std::cerr << "Error: ElfBinaryFile::GetMachine: The AMD x86-64
architecture is not supported yet\n";
            return (MACHINE) - 1;
        }
    // An unknown machine type
    std::cerr << "Error: ElfBinaryFile::GetMachine: Unsupported machine type: "
              << machine << " (0x" << std::hex << machine << ")\n";
    std::cerr << "(Please add a description for this type, thanks!)\n";
    return (MACHINE) - 1;
}
...
--- snip ---

There is nothing to fix here. Decompiling x86 ELF/PE works fine.
