error: qrc_qml.obj: requires unsupported dynamic reloc R_ARM_REL32; recompile with -fPIC解决办法

使用qtcreator加androidndk编译项目时报错：

error: qrc_qml.obj: requires unsupported dynamic reloc R_ARM_REL32; recompile with -fPIC

error: undefined reference to '__dso_handle'

解决方案，建一个头文件，代码如下，包含到项目里:

#define NS_EXPORT

extern "C" {
/*
 * To work around http://code.google.com/p/android/issues/detail?id=23203
 * we don't link with the crt objects. In some configurations, this means
 * a lack of the __dso_handle symbol because it is defined there, and
 * depending on the android platform and ndk versions used, it may or may
 * not be defined in libc.so. In the latter case, we fail to link. Defining
 * it here as weak makes us provide the symbol when it's not provided by
 * the crt objects, making the change transparent for future NDKs that
 * would fix the original problem. On older NDKs, it is not a problem
 * either because the way __dso_handle was used was already broken (and
 * the custom linker works around it).
 */
  NS_EXPORT __attribute__((weak)) void *__dso_handle;
}
