Linux build doesn't like reference to cstdint...

[mzimmers]

...as an include file. A line like this:

@#include <cstdint>
@

Returns an error about needing a particular compiler flag, but:

@#include <stdint.h>
@

does just fine. Can someone explain why this is?

Thank you.

Which error and what compiler flag?

if you google a bit about cstdint, you find "this on stackoverflow":http://stackoverflow.com/questions/3137336/difference-between-cstdint-and-tr1-cstdint .
cstdint was not part of C99. It comes with tr1 of STL and goes to C++0x:

bq. <tr1/cstdint> is defined, as name suggests, in TR1, while <cstdint> is defined in c++0x.

bq. Since this stuff isn't standard yet I guess it's compiler specific so I'm talking about gcc. To compile with the non-tr1 one I must compile with -std=c++0x, but there is no such restriction when using tr1.

Gerolf: thanks for the answer. I never knew what tr1 was until I searched on it just now. Interesting stuff.

Lukas: as you can probably guess from Gerolf's response, the error was about using some non-standard include file without the flag that enables C++0x. (I'm not booted in ubuntu right now, or I could be more specific.)

Would I be mostly correct in assuming that this is really no big deal to me, and I can just use the tr1/ versions without repercussion?
