Conflict between config.h and system header

Conflict between config.h and system header

[Daniel Bünzli]

Hello,

I have a conflict between the uint32 typedef of config.h and the  
system header Security.h on osx. Does anybody know how to work around  
this kind of problems (C compiler flag or preprocessor hack) ?

Related bugs are [1,2], is there any plan to clean the headers for  
3.10 ?

Thanks for your answers,

Daniel

My apologies - I sent this to Daniel directly rather than to the list.

I can't get in to caml.inria.fr to see the relevant bug reports, but I
have similar issues with writing HDF library bindings.  I've ended up
using the following preprocessor lines in my C code to get around this
(the OCaml headers are included above the pasted code):

---BEGIN PASTE
// XXX BEGIN HORRIBLE HACK
#define int32 hdf_int32
#define uint32 hdf_uint32
#define int8 hdf_int8
#define uint8 hdf_uint8
#define int16 hdf_int16
#define uint16 hdf_uint16

#include <hdf.h>

#undef int32
#undef uint32
#undef int8
#undef uint8
#undef int16
#undef uint16
// XXX END HORRIBLE HACK
---END PASTE

I then have to use hdf_int32 and so on in the body of the code
occasionally to silence compiler warnings.

I don't know that this is the best way, but in my case it has allowed
me to do what I need to until a better solution comes along.

Thanks a lot, it works. You saved me time, I should have thought a  
little longer.
