I need help to compile Pseudo-C code generated with IDA Pro and the Hex-Rays decompiler plugin. It shows an error on this line:

int (__thiscall *off_401F14)(void *, char); // weak


error C2143: syntax error : missing ')' before '*'

I don't see any error on that line. What's wrong?

  • Which compiler (and version) are you trying this in? Please edit your question. Also, this looks off-topic as it concerns forward engineering - and yes, I realize that the tool used is mainly used in RCE.

    @0xC0000022L I agree that the question lack vital information, However, I find this question related to the site. Decompiler are part of the RE process, and compiling the output is absolutly relevant to RE. Apr 30, 2013 at 19:36
  • it will not solve your problem, of a missing call type, but you should include "defs.h" ( found in the hexrays sdk ) in your file, it contains several macros used by hexrays. May 21, 2013 at 9:16
  • o, and what is wrong, is that '__thiscall' is apparently not defined for your compiler, you should '#define __thiscall' it to nothing to get rid of this specific error May 21, 2013 at 9:18

The following code compiles just fine for me as a .cpp file in Visual C++:

int (__thiscall *off_401F14)(void *, char); // weak

int main(int argc, wchar_t* argv[])
    return 0;

Perhaps you placed the function prototype inside of a function by accident or compiled it as C (file extension .c) file?

  • you obviously made assumptions about the compiler, so you should add on which compiler (and version) this compiles just fine.

    I didn't make assumptions about his compiler... "error C2143: syntax error : missing ')' before '*'" is a VC++ compiler error, and I tested my code above with VC++. Apr 30, 2013 at 14:12

    it likely is, I agree. But which version? Also it depends (the __thiscall) whether you throw it into a .cpp or a .c file ;) ... you mention neither and neither does the OP. I find the question extremely badly worded.

    Actually, you raise a very good point. It looks like it could be because the OP was using a .c file instead of a .cpp file. Apr 30, 2013 at 14:16
