android4.0编译错误集（一）

1、Android library 'XXX.so' not in prelink map 错误解决
在编译自己的Android library时可能会出现
library 'XXX.so' not in prelink map 错误，
这是由于Android的预编译设置引起的，/build/core/prelink-linux-arm.map文件描述了预编译的模块

需要修改所在文件夹下的android.mk文件
增加
LOCAL_PRELINK_MODULE := false
将预编译关闭，即可通过。

2、错误一：error: ‘ptrdiff_t’ does not name a type

解决方法：
$vi external/gtest/src/../include/gtest/internal/gtest-param-util.h
#include <cstddef>

3.错误二：undefined reference to `pthread_mutexattr_destroy'

collect2: ld returned 1 exit status
make: *** [out/host/linux-x86/obj/EXECUTABLES/test-librsloader_intermediates/test-librsloader] Error 1
make: *** Waiting for unfinished jobs....
解决方法：
$vi external/llvm/llvm-host-build.mk
LOCAL_LDLIBS := -lpthread -ldl

下面这个解决方法没成功，会有新的错误：errors again :can't find threads.h file or dir.
$ vi external/llvm/lib/Support/Android.mk
LOCAL_C_INCLUDES += system/core/include/cutils
LOCAL_SHARED_LIBRARIES := libcutil
$ vi external/llvm/lib/Support/Mutex.cpp
#include <threads.h>
$ vi external/llvm/lib/Support/Threading.cpp
#include <threads.h>

4.错误三：error: variable ‘ParamName’ set but not used [-Werror=unused-but-set-variable]
frameworks/compile/slang/slang_rs_export_foreach.cpp:247:23: error: variable ‘ParamName’ set but not used [-Werror=unused-but-set-variable]
cc1plus: all warnings being treated as errors
解决方法：
$ vi frameworks/compile/slang/Android.mk
#local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter -Werror
local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter

5、2.3以上系统使用JDK1.6，所以必须下载并设定其编译环境
vi ~/.bashrc

export JAVA_HOME=/usr/java/jdk1.6.0_23
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/bin/tools.jar:$JRE_HOME/bin
export ANDROID_JAVA_HOME=$JAVA_HOME

6、Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
解决:
内存不足

7、external/jsilver/src/com/google/streamhtmlparser/util/JavascriptTokenBuffer.java:80: cannot find symbol
symbol : method copyOf(char[],int)
解决：
把sdk从1.5升级到1.6

8、arm-eabi-4.4.3 version `GLIBC_2.11' not found
解决方法
prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-gcc -mthumb-interwork -Ibionic/libc/private -o out/target/product/generic/obj/lib/crtbegin_dynamic.o -c bionic/libc/arch-arm/bionic/crtbegin_dynamic.S
prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-gcc: /lib/tls/i686/cmov/libc.so.6: version `GLIBC_2.11' not found (required by prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-gcc)
make: *** [out/target/product/generic/obj/lib/crtbegin_dynamic.o] 错误 1

这是在32位Ubuntu上编译引起的arm-eabi-4.4.3版本问题，所以需要修改arm-eabi-4.4.0：
$ mv arm-eabi-4.4.3 to arm-eabi-4.4.3.old
$ ln -s arm-eabi-4.4.0 arm-eabi-4.4.3

or:
升级glibc或者系统

9、
PassFailButtons.java:191: onCreateDialog(int,android.os.Bundle) in android.app.Activity cannot implement onCreateDialog(int,android.os.Bundle) in com.android.cts.verifier.PassFailButtons.PassFailActivity; attempting to assign weaker access privileges;
解决：
很可能是因为使用了openjdk，而非sun-java6-jdk，

10、
undefined reference to __asprintf_chk
解决：
可能会由于stdio2.h导致编译错误。正确的stdio2.h是./prebuilt/linux-x86/toolchain/i686-linux-glibc2.7-4.4.3/sysroot/usr/bits/stdio2.h文件，请重新设置PATH环境变量，将./prebuilt/linux-x86/toolchain/i686-linux-glibc2.7-4.4.3/sysroot/usr放在PATH的最前。
cp ./prebuilt/linux-x86/ toolchain/i686-unknown-linux-gnu-4.2.1/lib/libbfd.a ./out/host/linux-
x86/obj/STATIC_LIBRARIES/libbfd_intermediates/libbfd.a
可能 glibc版本不是最新的

11、
SDL init failure, reason is: No available video device .
解决：
原因是他依赖X11，可以进入图形化界面来运行。
