error: ‘btintptr_t’ was not declared in this scope for BUILD_EXTRAS

The Error...

/bullet3/Extras/Serialize/makesdna/makesdna.cpp:1068:9: error: ‘btintptr_t’ was not declared in this scope

It compiles fine on Windows, Linux and Mac OSX, so please provide ALL details, including operating system+version, compiler+version, all build system steps etc.

Just had this on Linux as well. I could compile it recently, but not anymore since I upgraded TF. I tried to remember the changes, but could not find the reason. Is 'btintptr_t' defined somewhere for Linux? I could not find any reference in the code where it would be defined in the linux case...

If your compiler does not define _INTPTR_T_DEFINED and neither declares intptr_t somewhere (c++11 not enabled?) then declaring btintptr_t as intptr_t is equal to btintptr_t not being declared.

I suppose that macro condition can be written as:

#if defined(INTPTR_MIN) || defined(INTPTR_MAX)
	typedef intptr_t btintptr_t;
#elif defined(_WIN64)
	typedef __int64 btintptr_t;
#else
	typedef long btintptr_t;
#endif

Although I don't see stdint.h included anywhere in there.

EDIT: nvm, stdint.h is included but is after that macro. which probably causes the mess.

EDIT2: Upon closer look, btintptr_t seems to be declared only on windows in the _WIN32 branch of the macros. Lack of indentation made it a bit harder to notice.

I just had this same issue compiling makesDNA on mac:
/Users/nickolai.belakovski/develop/bullet3/Extras/Serialize/makesdna/makesdna.cpp:1074:9: error: use of undeclared identifier 'btintptr_t'
It looks like the #defines that have been referenced in this thread resolve to #include <inttypes.h> for Mac. Adding typedef long btintptr_t right after that include fixed the compile issue, not sure if that's the desired fix though.

[erwincoumans]

Why/how would you compile makesdna.cpp? The file is optional and shouldn't be compiled by default. Did you use cmake and set INTERNAL_UPDATE_SERIALIZATION_STRUCTURES to ON (it is OFF) by default?
If so, can you just turn it OFF again?

[nbelakovski]

I'm trying to extend the serialization structures, so, yea, I am compiling this on purpose.
