Errors during 'gradlew build' #146

Closed chanijjani closed 4 years ago

chanijjani commented 4 years ago

Dear NNStreamer maintainers,

I faced following logs when I tried to build a sample app (android/nnstreamer-ssd) using gradlew. (Though I temporarily made "try {} catch {}" as comments and succeeded the build.)

~/nnstreamer/nnstreamer/gst/nnstreamer/tensor_filter/tensor_filter_support_cc.cc:75:3: error: cannot use 'try' with exceptions disabled try { ^ ~/nnstreamer/nnstreamer/gst/nnstreamer/tensor_filter/tensor_filter_support_cc.cc:137:3: error: cannot use 'try' with exceptions disabled try { ^ ~/nnstreamer/nnstreamer/gst/nnstreamer/tensor_filter/tensor_filter_support_cc.cc:173:3: error: cannot use 'try' with exceptions disabled try { ^ 3 errors generated. make: *** [/home/chanhee/Android/Sdk/ndk/21.1.6352462/build/core/build-binary.mk:478:

How could I resolve this issue..?

Note that I'm using Android Sdk and Ndk as follows. android { compileSdkVersion 24 ndkVersion "21.1.6352462" buildToolsVersion '28.0.3' ... }

@jaeyun-jung Please look into this Android build issue (or reassign to anyone who's capable).

@chanijjani : 1. Please specify how are you building which build files and how do you include nnstreamer binaries? (you appear to build nnstreamer, not nnstreamer-example)

  1. Will you try to add -frtti -fexceptions compiler flags?
jaeyun-jung commented 4 years ago

try()-catch() requires flag -fexceptions. https://developer.android.com/ndk/guides/cpp-support#c_exceptions

However, I am not sure why these error occurs. (In Android-nnstreaer.mk it includes -fexceptions flag. Please add below to prevent build error. I will import and revise the mk files in android examples.

LOCAL_CXXFLAGS := -std=c++11 -fPIC -frtti -fexceptions -DVERSION=\"$(NNSTREAMER_VERSION)\"

@jaeyun-jung Is #148 fixing this?

chanijjani commented 4 years ago

Thank you so much for kind and quick replies. I'll apply #148 and share results.

chanijjani commented 4 years ago

I applied #148. Then it works as follows.

Thank you again!
