應該是SDL的h檔
SDL的lib跟include
還有X的lib都加了
可是還是類似的錯誤訊息
只是前面的
/usr/local/hybus-arm-linux-R1.1/arm-linux/bin/ld: warning: libX11.so.6, needed by /usr/local/hybus-arm-linux-R1.1/lib/gcc-lib/arm-linux/2.95.3/usr/lib/libSDL.so, not found (try using -rpath or -rpath-link)
/usr/local/hybus-arm-linux-R1.1/arm-linux/bin/ld: warning: libXext.so.6, needed by /usr/local/hybus-arm-linux-R1.1/lib/gcc-lib/arm-linux/2.95.3/usr/lib/libSDL.so, not found (try using -rpath or -rpath-link)
沒有了
剩下後面的主要是
undefined reference to `SDL_XXXXXX'
都是跟SDL有關的~~
大概還有漏檔案吧

晚點再試~~
