在ubuntu x86_64 GCC4.6上ics编译错误以及解决办法
问题1：
<command-line>:0:0:warning:"_FORTIFY_SOURCE" redefined [enabled by default]
<built-in>:0:0:note: this is the location of theprevious definition
hostExecutable:mksnapshot(out/host/linux-x86/obj/EXECUTABLES/mksnapshot_intermediates/mksnapshot)

icscompile fail!
解决办法：参考http://code.google.com/p/android/issues/detail?id=20795
修改build/core/combo/HOST_linux-x86.mk：
-HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
+HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE-D_FORTIFY_SOURCE=0
问题2：
make[1]: Leavingdirectory`ics/device/hisilicon/godbox/driver/sdk/msp/android_driver/RT3090_LinuxSTA_V2.3.1.4_20100222'
之后就报错了。看不出什么原因。重新make试试；
->重新make居然就过去了。

解决方法参考http://code.google.com/p/android/issues/detail?id=23206：
Adding a "#include <stddef.h>" tolinker.cppfixes the issue
The full location of the linker.cpp fileis"external/mesa3d/src/glsl/linker.cpp" from with in yourandroidsource directory.
（Problem comes from host libstdc++. Since version4.6<cstdio> does not include <cstddef> anymore.
Downgrade host package to libstdc++ 4.5 or add'#include<cstddef>' into linker.cpp）
问题4：
external/oprofile/libpp/format_output.h:94:22:error:reference 'counts' cannot be declared 'mutable'
解决办法：http://code.google.com/p/android/issues/detail?id=22003
Fix/Work-around:
-mutable counts_t & counts;
+counts_t & counts;
问题5：
external/gtest/src/../include/gtest/internal/gtest-param-util.h:122:11:error:'ptrdiff_t' does not name a type
解决办法：http://code.google.com/p/android/issues/detail?id=22005
external/gtest/include/gtest/internal/gtest-param-util.h
#include<vector>
+#include <cstddef>
#include<gtest/internal/gtest-port.h>
问题6：external/llvm/lib/Support/Mutex.cpp:143:undefinedreference to `pthread_mutex_trylock'
解决方法：http://code.google.com/p/android/issues/detail?id=22011
Add "LOCAL_LDLIBS := -lpthread -ldl"inexternal/llvm/llvm-host-build.mk works for me.
问题7：frameworks/compile/slang/slang_rs_export_foreach.cpp:249:23:error:variable 'ParamName' set but not used
解决办法：

$vimframeworks/compile/slang/Android.mk
将 local_cflags_for_slang 所在行最后的 -Werror 去掉：
#local_cflags_for_slang:=-Wno-sign-promo -Wall -Wno-unused-parameter -Werror
local_cflags_for_slang := -Wno-sign-promo-Wall-Wno-unused-parameter
另外，将gcc版本降低为4.4可以避免ics编译错误：
sudo apt-getinstall gcc-4.4
sudo apt-getinstall g++-4.4
sudo ln -s/usr/bin/gcc-4.4/usr/bin/gcc
sudo ln -s/usr/bin/g++-4.4/usr/bin/g++
