Typedef Forward Declaration
a minute: Sign up Avoiding “redefinition of typedef” warnings when defining structs up vote 0 down vote favorite 1 I'm defining some structs which reference eachother, and typedef'ing the structs before using them, so each struct is 'aware' of the others (was getting compilation errors without this). Not sure if this is necessary, or correct. Now when compiling with gcc, I'm c typedef getting "redefinition of typedef" warnings. What's the correct way to go about this? typedef struct a A; typedef struct b B; typedef struct c C; struct a { B* list; A* parent; }; struct b { A* current; B* next; }; struct c { A* current; A* root; }; UPDATE: Dumb, bad copy-pasting resulted in this header being included twice in another file. I'm new to C and thought it must have something to do with having the structs in the file twice. Thanks @Kevin Ballard for the heads up. c gcc struct typedef share|improve this question edited Mar 13 '12 at 0:18 asked Mar 13 '12 at 0:04 Bort 5,07012040 4 "redefinition of typedef"? Are you sure you aren't importing the same header twice without header guards? –Kevin Ballard Mar 13 '12 at 0:09 1 This code compiles fine.

Visual Studio is working fine, I can compile other C programs with it http://stackoverflow.com/questions/9676586/avoiding-redefinition-of-typedef-warnings-when-defining-structs successfully (e.g. mozjpeg, pngwolf-zopfli, etc.) When I try to compile gifsicle with the following command: nmake -f Makefile.w32 I get this error: clp.c clp.c(44) : error C2371: 'uintptr_t' : redefinition; different basic types C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\vadefs.h(46) : see declaration of 'uintptr_t' There seems to be a re-declaration of uintptr_t... Can you help and tell me how to fix it? Thanks! Owner kohler commented https://github.com/kohler/gifsicle/issues/41 Aug 10, 2015 Hi, I don't support Windows builds in general. However, you may be able to get around this by editing src/win32cfg.h. Try changing this line /* #undef HAVE_INTTYPES_H */ to #define HAVE_INTTYPES_H 1 and do something similar to the HAVE_STDINT_H line. tssajo commented Aug 10, 2015 @kohler I managed to compile gifsicle under Windows 7 with MS Visual Studio 2010. I can submit a patch, in case you want to include Windows compilation support. I had to modify a few lines in about 4-6 files. Owner kohler commented Aug 10, 2015 I'm happy to look at a patch! … On Mon, Aug 10, 2015 at 11:13 AM, Zoltan ***@***.***> wrote: @kohler
