Build error with std namespace functions #32 REOPEN
Hi,
I got the same error #32 of undefined references, with the current git environment. Undefined references when building shared library libandroid_dlib.so [x86_64] SharedLibrary : libandroid_dlib.so jni/jni_detections/detector.h:42: error: undefined reference to 'cv::HOGDescriptor::detectMultiScale(c
This is how Application.mk looks
NDK_TOOLCHAIN_VERSION := clang APP_ABI := x86_64 arm64-v8a APP_CPPFLAGS := -std=c++11 -frtti -fexceptions APP_PLATFORM := android-28 APP_STL := c++_static #APP_CFLAGS+=-DDLIB_NO_GUI_SUPPORT=on #APP_CFLAGS+=-DDLIB_PNG_SUPPORT=off APP_CFLAGS+=-DDLIB_JPEG_SUPPORT=on APP_CFLAGS+=-DDLIB_JPEG_STATIC=on
Any ideas ? Thanks !
I am facing the same error as well. Did you manage to find any workaround for this?
I am using latest version of NDK Dlib - 19.1
I met the same error with another library, and spent DAYS before understanding what happens. It comes from the version of the NDK. Since NDK r18 or something, cross-compiler and toolchain is using CLANG. Before it was GCC and this kind of link error did not show up. Try to downgrade your NDK version to r14 or 15 and run again the compilation. Please post the results then, I would be curious to know
Thanks for your reply. Worked with r-15c using gnustl_static, didn't work with c++_static or c++_shared.
thank you so much for your information, it worked with [Android NDK, Revision 15c (July 2017)] using gnustl_static. I use Python 2.7.16, macOS Mojave version 10.14.4 Here is what I got:

I also facing the same issue, Initially, I tried with the latest NDK r21e, after going through this thread, changed NDK version to r15c, Still facing the same issue. Any inputs?
Versions:
DLib = 19.1 OSX = Big Sur 11.2.3 NDK = r21e and r15c
Applicaiton.mk:

Tried options:
