You need to load the value to an "lType" type....

you're not showing enough code. What does accept() do? Based on your description, I strongly suspect that your alloca and constant are not the same type. Remember that alloca returns a pointer type that you must load to get at the actual variable.

Hi All, I'm writing a code generation with my compiler. I read sever example and documentation but I did understand what I make wrong. What I try to do is a compare a local variable with a constant. But when I create a ICMP instruction I get that instruction are not of same type. I'm using llvm by svn repository updated at two week ago. The code that I try to generation is something
