I'm not sure if the libogg, libvorbis, or libshout installation caused the following problem. libogg and libvorbis seemed to install without any errors on my Mac OS X 10.4, but for some reason when I tried configuring libshout it died with this message: "configure:23903: error: requisite Ogg Vorbis library not found." I looked through the config.log file and found this error: /usr/local/include/ogg/config_types.h:6: error: parse error before 'ogg_uint16_t' /usr/local/include/ogg/config_types.h:8: error: parse error before 'ogg_uint32_t' I found /usr/local/include/ogg/config_types.h had the following: /* these are filled in by configure */ typedef int16_t ogg_int16_t; typedef u_int16_t ogg_uint16_t; INSTEAD OF typedef u_int16_t ogg_uint16_t typedef int32_t ogg_int32_t; typedef u_int32_t ogg_uint32_t; INSTEAD OF typedef u_int32_t ogg_uint32_t typedef int64_t ogg_int64_t; I'm not sure why it would have uint16_t since /usr/local/include/ogg/os_types.h doesn't have uint16_t under any of its OS sections. I manually changed those two values to what ogg/os_types.h had for my OS and ran ./configure again, and the error message went away. I hope this helps anyone else who has this problem. -Paulie
