我從網上下載了smpeg-0.4.4.tar.gz，通過它安裝了smpeg庫。其相關目錄如下：
/usr/local/lib # ls
directfb-1.0-0 libdirect.la libiconv.la libSDL.la libSDL_mixer.so libsmpeg.so
libcharset.a libfreetype.a libSDL-1.2.so.0 libSDLmain.a libSDL.so libsmpeg.so.0
libcharset.la libfreetype.la libSDL-1.2.so.0.11.2 libSDL_mixer-1.2.so.0 libsmpeg-0.4.so.0 pkgconfig
libdirect.a libfusion.a libSDL.a libSDL_mixer-1.2.so.0.2.6 libsmpeg-0.4.so.0.1.3 preloadable_libiconv.so
libdirectfb.a libfusion.la libSDL_image.a libSDL_mixer.a libsmpeg.a
libdirectfb.la libiconv.a libSDL_image.la libSDL_mixer.la libsmpeg.la
/usr/local/bin # ls
directfb-config freetype-config glmovie iconv plaympeg sdl-config smpeg-config
然後我又下載了SDL_mixer-1.2.8.tar.tar，想通過它安裝sdl_mixer庫。結果./configure時提示我以下信息：
#./configure --prefix=/usr/local --enable-static=yes --with-smpeg-prefix=/usr/local --with-smpeg-exec-prefix=/usr/local
checking for smpeg-config... /usr/local/bin/smpeg-config
checking for SMPEG - version >= 0.4.3... no
*** Could not run SMPEG test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means SMPEG was incorrectly installed
*** or that you have moved SMPEG since it was installed. In the latter case, you
*** may want to edit the smpeg-config script: /usr/local/bin/smpeg-config
打開config.log，發現：

為什麼sdl_mixer用不上smpeg的庫文件呀？？？呼喚大牛！！！
