Where are the binaries for android?

[xhsoldier]

I built caffe2 for android by this: ./scripts/build_android.sh but where is the generated binaries?

libCAFFE2_NNPACK.a or libCAFFE2_PTHREADPOOL.a or libCaffe2_CPU.a? libCAFFE2_NNPACK.a is 328kb libCAFFE2_PTHREADPOOL.a is 8kb libCaffe2_CPU.a is 304M

For example, the AICamera example: https://github.com/bwasti/AICamera/ Caffe2 binaries used by AICamera, I can not generate these libraries.

You may check #339.

[xhsoldier]

I do not think these two question are the same. #339 is android build optimization, I built successful, but I can not find the output binaries used by AICamera.

[odol0503]

libCaffe2_CPU.a is caffe2's main library. But it is not optimized. If you set -O3 option, you can get about 40MB caffe2 library. And if you exclude some OPs you don't need, you can get a smaller size caffe2 library.

I think it is good to use the stable version like v0.7.0 not the latest version.

thx

when I user libCaffe2_CPU.a in android studio project, I get this error: Error:error: undefined reference to 'caffe2::EnforceNotMet::EnforceNotMet(char const, int, char const, std::string const&)'

@odol0503 Could you tell me why v0.7.0 is better?

[odol0503]

caffe2 v0.7.0 is official version, although caffe2 v1.0 is not released yet. To avoid meeting unexpected issues, it is recommended to use official version.

thx

I have the same question,only use libCaffe2_CPU.a in my android project?

[odol0503]

Sorry, I don't catch what you mean. If you mean you can use only libCaffe2_CPU.a library, it can you use it alone or linking with other libraries like NNPACK.
