typedef int8_t int_least8_t;
typedef int16_t int_least16_t;

der Fehler lautet:

1>c:\dokumente und einstellungen\ortalo\eigene dateien\visual studio 2008\projects\teensydll\teensydll\stdint.h(8) : error C2144: Syntaxfehler: 'int' sollte auf ';' folgen

Im header file inttypes.h sind die beiden Typen (int8_t und int16_t) aber definiert.

Kann mir hier jemand verraten, wo der Fehler liegt?

Vielen Dank im Voraus!

stdint.h benutzt man in C++ nicht.

Und wenn du endlich mal erklären würdest warum wären deine Antworten brauchbar und weniger arrogant... (sry musste mal sein).

stdint.h ist C.
In C++ heißt das

#include <cstdint>

Aber ob das deinen Fehler bereinigt?
Evtl. mal den fehlerhaften Code posten, wenns noch nicht hilft.

Dann wären es aber nicht meine Antworten.

Nein, <cstdint> ist keine Headerdatei des C++-Standards.

<stdint.h> ist ein Header von C99, den viele Standardbibliotheken mit sich bringen. Es gäbe auch noch <boost/cstdint.hpp> , falls man Boost benutzt.

Jepp, habs auch grad gesehen.
Im GCC gibt es allerdings ein cstdint, allerdings für C++0x. Scheinbar kommt das mit dem neuen Standard.
Ansonsten liegt auch ein cstdint im tr1. Boost sollte es dann nicht brauchen.

// This code will someday be turned into "librawhid", an easy-to-use

// The linux version doesn't extract usage and usage page from the
// report descriptor and just hardcodes a signature for the Teensy

// manage multiple devices and robust detection of device removal
// and attachment.  There are probably lots of other issues... this

Die ersten paar Zeilen ,diemit extern "C" beginnen, habe ich lt. einer Anleitung eingefügt; hoffe die stimmen. Nur kompilieren läßt er sich net.
Könnte mir evt. jemand den Code so abändern, daß ich ihn benutzen kann?
