Given that older versions might not support it, and might not have <stdint.h>, it's probably best not to use it.FreeBSD 10 doesn't have int8_t in /usr/includes/stdint.h.
From a quick look at the current FreeBSD source (from SVN), /usr/include/sys/stdint.h includes a bunch of other header files, including <sys/_stdint.h>, which typedefs int8_t and the other C99 types. It typedefs them in terms of types defined in $ARCHITECTURE/include/_types.h. Multi-platform OSes, especially those running on both 32-bit and 64-bit platforms, tend to have a twisty little maze of header files, all different, for things such as that.
I know we used to avoid using C99 things like that, but do we compile in such a way to make the compiler not work with C99 code?
Yes, we compile without including <stdint.h>, except on Windows. On some platforms, the stdint.h types are either defined in a different header, or we happen to include a header that happens to transitive-closure-of-include <stdint.h>. On FreeBSD, apparently not so. ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
