NAN is defined in math.h except on MSVC where it is defined in xmath.h. Fixes compilation with MSVC. --- gst/matroska/ebml-read.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'gst/matroska/ebml-read.c') diff --git a/gst/matroska/ebml-read.c b/gst/matroska/ebml-read.c index 6ce679da..2220a229 100644 --- a/gst/matroska/ebml-read.c +++ b/gst/matroska/ebml-read.c @@ -31,6 +31,16 @@ #include +/* NAN is supposed to be in math.h, Microsoft defines it in xmath.h */ +#ifdef _MSC_VER +#include +#endif + +/* If everything goes wrong try 0.0/0.0 which should be NAN */ +#ifndef NAN +#define NAN (0.0 / 0.0) +#endif + GST_DEBUG_CATEGORY_STATIC (ebmlread_debug); #define GST_CAT_DEFAULT ebmlread_debug @@ -706,7 +716,7 @@ _ext2dbl (guint8 * data) m = (m << 8) + ext.mantissa[i]; e = (((gint) ext.exponent[0] & 0x7f) << 8) | ext.exponent[1]; if (e == 0x7fff && m) - return 0.0 / 0.0; + return NAN; e -= 16383 + 63; /* In IEEE 80 bits, the whole (i.e. 1.xxxx) * mantissa bit is written as opposed to the * single and double precision formats */ -- cgit
