有没有办法让Android NDK-build使用更新版本的gcc？

Question

I installed Android NDK r5b Windows version, and I use cygwin to compile the C code.

I see the NDK-build is actually calling C:\\android-ndk-r5b\\toolchains\\arm-linux-androideabi-4.4.3\\prebuilt\\windows\\bin\\arm-linux-androideabi-gcc-4.4.3 to compile. I wonder if there is a way to let NDK-build use a newer version of gcc?

The reason I want to do this is:

Gcc4.4.3 has known bug on generating not optimal assembly code for certain NEON intrinsics
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43118

The newly released GCC 4.6 claims that it has some improvements for ARM and intrinsics. So I want try to have NDK-build use GCC4.6.

Answer 1

I believe your question would be answered by this NDK documentation: docs/STANDALONE-TOOLCHAIN.html . It sounds to me like you know what you're doing, so just heed the warnings and happy hacking. I believe section 3 "Invoking the compiler (the easy way)" is what you're looking for.

Answer 2

There is an alternative NDK build: http://www.crystax.net/en/android/ndk/7

It includes gcc 4.6.3.

Answer 3

在试图自己回答这个问题时，我偶然发现了这个问题，这是一个用GCC 4.6成功构建工具链的人的逐步说明： http ： //glandium.org/blog/ ？p = 21460 。

Answer 4

Android NDK 8b is released, featuring GCC 4.6 as the default toolchain.
