I'm trying to integrate some opensource code that's using inline assembly into my application. Compiling throws C2415 improper operand type, and I can't find any information on what might be wrong and how to fix it.

The original application that the code is from came compiled alongside source code and runs fine, though I don't know what compiler was used.

Code excerpt:

__asm {
    push rax
    push rbx
    push rcx
    push rdx
    push rdi
    lea  rdi, variable
    ...
}

The error occurs on LEA command, variable is char[100]

Post code that will *actually* reproduce this error when we try it ourselves. – Hans Passant May 25 '15 at 11:24
The source operand of `lea` needs to be a memory address, i.e. something of the form `[register + stride * index]`. – Kerrek SB May 25 '15 at 11:28
You also forgot to mention what compiler you are using. – Jester May 25 '15 at 11:32
