--------------fdk-aac-0.1.1 編譯過程中遇到的問題 ---------------------------

FAQ:
1. 顯示編譯過程 手工去掉Makefile中 
AM_DEFAULT_VERBOSITY = 0改為1

或-------------
am__v_CXX_0 = @echo   CXX    $@; 中紅色的@
   顯示鏈接過程
am__v_GEN_0 = echo   GEN    $@;



2. 實際的編譯命令行
echo   CXX    libSYS/src/cmdl_parser.lo;depbase=`echo libSYS/src/cmdl_parser.lo | sed 's|[^/]*$|.deps/&|;s|.lo$||'`;

紅色部分是自己加的

實際鏈接的命令行:
arm-linux-androideabi-gcc -shared  -fPIC -DPIC  libAACdec/src/.libs/aacdec_drc.o ... libSYS/src/.libs/wav_file.o   -lgcc -L/opt/ndk/android-ndk-r8e/platforms/android-14/arch-arm/usr/lib -lm  -O2 -Wl,-Bsymbolic -Wl,-soname -Wl,libfdk-aac.so --sysroot=/opt/ndk/android-ndk-r8e/platforms/android-14/arch-arm -Wl,--no-undefined -Wl,-z -Wl,noexecstack -Wl,-z -Wl,relro -Wl,-z -Wl,now   -Wl,-soname -Wl,libfdk-aac.so.0 -Wl,-version-script -Wl,.libs/libfdk-aac.ver -o .libs/libfdk-aac.so.0.0.2


3. 編譯libSYS/src/cmdl_parser.cpp出錯 
stdio.h:57:9: error: 'off_t' does not name a type
注掉：
//#define _SYS_TYPES_H_

4. libSYS/src/genericStds.cpp:108 ： stdio.h:57:9: error: 'off_t' does not name a type
修改libSYSincludegenericStds.h
//#define _SYS_TYPES_H_

5. link: `libSYS/src/cmdl_parser.lo' is not a valid libtool object
重新配置和編譯一遍就行，應該是cmdl_parser.lo在編譯時的配置和其他的不一樣導致的，這個文件當時是手工編譯的
