添加环境变量 export PATH=/Cross/target/local/bin:$PATH
# ./configure --host=mipsel-linux --build=i686-pc-linux --prefix=/opt --with
-sdl-prefix=/opt --enable-jpg --enable-png :LIBPNG_CFLAGS=“-I/opt/include

#make
#make install
----------------------------若编译报错，请修改Makefile文件--------------------------
>CFLAGS= -I/opt/include/SDL
>LIBS=-Wl,rpath,/opt/lib –L/opt/lib –LSDL -lpthread
LIBPNG选项 添加成如下参数(默认为空):
>LIBPNG_CFLAGS = -I/opt/include/libpng13
>LIBPNG_LIBS = -lpng14
>LIBS = -Wl,-rpath,/opt/lib/ -L/opt/lib -lSDL -lpthread
SDL_CFLAGS、SDL_LIBS选项也修改成如下
>SDL_CFLAGS = -D_GUN_SOURCE=1 -D_REENTRANT -I/opt/include/SDL
>SDL_LIBS = -Wl,-rpath,/opt/lib -L/opt/lib -lSDL -lpthread
# make CC=mipsel-linux-gcc
# make install

添加环境变量 export PATH=/Cross/target/local/bin:$PATH
# ./configure –-host=mipsel-linux –-build=i686-pc-linux –-prefix=/opt --with-
sdl-prefix=/opt --with-freetype-prefix=/opt --without-x LDFLAGS=“-L/opt/lib
-lSDL -liconv -lfreetype”
#make
#make install
----------------------若编译不通过，请修改Makefile文件，添加依赖关系--------------------
>CFLAGS = -g -O2 -I/opt/include/freetype2 -I/opt/include -I/opt/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -I/opt/include
>FREETYPE_CONFIG = /opt/bin/freetype-config

# make CC=mipsel-linux-gcc AR=mipsel-linux-ar RANLIB=mipsel-linux-ranlib CXX=mipsel-linux-g++
# make install
若出现以下错误
/home/Cross/SDL_ttf-2.0.9/showfont.c:268:undefined reference to 'libiconv_open'
则修改149行参数为下图所示
LDFLAGS = -L/opt/lib -lSDL -liconv -lfreetype
再
# make CC=mipsel-linux-gcc AR=mipsel-linux-ar RANLIB=mipsel-linux-ranlib CXX=mipsel-linux-g++
# make install
