[What about linux] porting Madplay to embedded

Today, to test the audio of the EVB board, I transplanted Madplay to the Embedded Development Board. PC: Linux-2.6.18 SourceCode: libid3tag-0.15.1b.tar.gz zlib-1.1.4.tar.gz libmad-0.15.1b.tar.gz madplay-0.15.2b.tar.gz statement: 1. The working directory of this porting job is/home/mad/(any directory can be selected ). 2. The arm development platform for this migration has been set up, that is, the arm-linux cross-compilation tool has been installed, and the directory of the Cross-compilation tool is/usr/local/arm/2.95.3/bin. Step: 1. decompress the above sourcecode in the working directory and create a folder lib to put the compiled file. 2. Enter the zlib decompressed directory. to port to the arm platform, you need to modify the configure file line 24th: 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) "alt =" "/> AR =$ {AR-" ar rc "} is changed to 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) "alt =" "/> AR =$ {AR-"/usr/local/arm/2.95.3/bin/arm-linux-ar rcs "} 25th rows 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) "alt =" "/> RANLIB =$ {RANLIB-" ranlib "} changed to 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) "alt =" "/> RANLIB =$ {RANLIB-"/usr/local/arm/2.95.3/bin/arm-linux-ranlib "} 63rd rows 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src)" alt = ""/> cc =$ {CC-gcc} changed to 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) "alt =" "/> cc =$ {CC-/usr/local/arm/2.95.3/bin/arm-linux-gcc} 3. perform the following operations: 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src) 'align =" top "src =" http://www.bkjia.com/uploads/allimg/131228/1R0495J6-0.gif "Onclick =" window. open (" http://blog.51cto.com/viewpic.php?refimg= "+ This. src)" alt = ""/>./configure -- prefix =/home/mad/lib
