QUESTION
I am trying to build a cross compiling system on ubuntu 16.04 to shorten the compile time.
I have installed the tools and copied libs from the raspberry pi and definitely a simple "Hello world" example works very well.
The problem occurred when I tried to build a program with cmake and opencv. Obviously it does not find OpenCVConfig.cmake in the host system as it only exists on rpi in the following folder:
/usr/local/lib/cmake/opencv4$
Can I just copy /usr/local/lib/cmake folder to host computer and manually modify the library install path or how should I do it?
Error message:
Could not find a package configuration file provided by "OpenCV" with any of the following names:
...ANSWER
Answered 2020-Aug-26 at 13:43In your scenario, you have the package installed in a custom location.
You can try the following (from the cmake manual):
The default search order is designed to be most-specific to least-specific for common use cases. Projects may override the order by simply calling the command multiple times and using the NO_* options:
find_package ( PATHS paths... NO_DEFAULT_PATH)

Getting stackoverflowerror from Gson while converting hashmap to JSON object
So how can we fix this? It depends on what behavior you want. One easy option is to prevent Gson from attempting to serialize the parent field (we don't need it, as we can reconstruct it from the children list). To do this just mark parent as transient and Gson will not include it in the result.
QUESTION
I am trying to run a NDK and OpenCV related project. The project builds errorless. But when i run the application I get the error:
mips64el-linux-android-g++: error: unrecognized command line option '-mfpu=neon'
My Application.mk file looks like this:
...ANSWER
Answered 2017-Mar-29 at 22:19By default you'll build for every NDK ABI: arm5, arm7, arm64, mips, mips64, x86, and x86_64, but -mfpu=neon is only valid for arm7 and arm64.
In general for cases like this you need to protect architecture specific flags by testing against TARGET_ARCH_ABI, but for NEON support there's a flag just for this:
