Missing includes

[spworley]

When compiling with gcc 4.6 in Linux, two needed includes are missing from imgui.cpp:
limits.h
stdint.h

[septag]

had that problem too, fixed it by adding those two includes to imgui.cpp

Thanks! Shouldn't either limits.h or stdint.h be enough? Is the error you were getting the lack of INT_MAX only? Trying to be very explicit and document why such and such are included in the code. If you could paste the compilation error it would be great.

Sure, (compiled with clang)

imgui.cpp:912:27: error: use of undeclared identifier 'INT_MAX' FocusIdxRequestCurrent = INT_MAX;

imgui.cpp:2843:31: error: unknown type name 'intptr_t'; did you mean '__intptr_t'? const void* ptr_id = (void*)(intptr_t)int_id;

first one solved by including limits.h, second one by including stdint.h

[ocornut]

Thanks, it is fixed in trunk now.

Just had a report that limits.h doesn't exist on OSX.
Could you tell me if include stdint.h only fix the build on your setup? (wikipedia implies that stdint.h is a superset of limits.h). Thanks.

Removing limits.h , still brings INT_MAX not found error
However there is INT32_MAX defined inside stdint.h, I guess you could use that one.

I removed the need for INT_MAX to simplify anyway, it was only used as a marker for a value being "unset".
