[Caffe2]Build caffe2 for android having large .a lib

wang5566 opened this issue 6 years ago · comments

I built caffe2 for android using script/build_android.sh and passed through. But I got libcaffe2.a not libcaffe2.so and the .a lib is too large about 1G. Is it normal?

@wang5566 yes this is normal. After linking in app, size becomes much smaller, because most symbols and debug info are removed
