unsupported dynamic reloc R_ARM_REL32 AND hidden symbol '__dso_handle' is not defined
项目里编译codec
src\makefiles\android\codec\Makefile
line 25 原本用 4.6 不会报错
-L/data/android/android-ndk/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi-v7a \
改成
-L/data/android/android-ndk/sources/cxx-stl/gnu-libstdc++/4.8/libs/armeabi-v7a \
编译报错 (下面只有四行)

相关的库文件是armeabi-v7a文件夹下 libgnustl_static.a
Google上有人解释说所引用crtbegin_so.o非PIC
https://code.google.com/p/android/issues/detail?id=23203
The problem is that there is a text relocation for __dso_handle. In other words, the code in crtbegin_so.o is not position independent.This is what gcc generates for the same code transposed in C, for arm (thumb would be different):
如果一定用4.8的话，按照

可以行得通。
