I am new to MediaPipe Framework. I went through their documentation setup and installation guide for opencv#3, bazel, homebrew. I did everything and I'm also able compile and execute their Hello World CPP file.
Now I want to generate AAR file of face_detection. Again I followed each and every step mentioned in their guide, but now I am stuck at a point where local repository of opencv#3 is not able to fetch.
I am working in MacOS Catalina -v 10.15.7
ERROR: /Users/rajeevkumar/Desktop/Android/mediapipe/third_party/BUILD:178:6: //third_party:opencv_binary depends on #macos_opencv//:opencv in repository #macos_opencv which failed to fetch. no such package '#macos_opencv//': The repository's path is "/usr/local/opt/opencv#3" (absolute: "/usr/local/opt/opencv#3") but this directory does not exist.

It seems you don't have opencv installed.
did you try running
https://github.com/google/mediapipe/blob/master/setup_opencv.sh
if you didn't, open terminal,go to mediapipe directory and use
./setup_opencv.sh
to install opencv and add necessary path to your WORKSPACE file.

I am trying to build an iOS app that is exposed to a fairly extensive Rust project, but I am having issues with one of the dependencies in the project. The Rust project has a ZMQ dependency, and while I am able to build the project on my Mac, when I try to incorporate the Rust project I get the following error:
error: failed to run custom build command for `zmq-sys v0.8.3`
Caused by:

I am trying to build the appropriate library for the iOS and iOS simulator architectures without relying on pkg-config, but if someone can provide useful instructions for configuring pkg-config for cross-compilation, I am not opposed to it, I just don't know how and can't find any up to date resources.
I have cloned the libzmq project from this github: https://github.com/zeromq/libzmq.git, then navigate into libzmq.
Inside libzmq, I run ./autogen.sh followed by ./configure --prefix [directory location] --target "aarch64-apple-ios", then make and make install.
The above procedure without the --target flag is how I got the project to compile on my Mac in the first place, and with the target flag in place make and make install both complete successfully, but when I try to build the project using PROJECT_DIR="${PWD}/ProjectName" ./ProjectName/build-rust.sh,
I get the previously posted error.
I am following the Swift-Bridge Book (https://chinedufn.github.io/swift-bridge/building/xcode-and-cargo/index.html) to try to load the Rust libraries into Xcode.
One thing to note: In the libzmq git hub, there is a folder called builds/ios/ and inside this folder is what looks to be a build file for all of the iOS archs, but I haven't been able to get the repo to build with that file. I think figuring out how to use the build_ios.sh build file as opposed to the standard build.sh provided might be the answer, but I've tried dropping build_ios.sh where build.sh is, and ./autogen.sh doesn't work, because it complains that it can't find configure.ac, even though this file does exist.
I know that someone already asked this question but it isn`t up to date anymore. Most of the links are dead and the commands are not relevant anymore.
I have read these
Compile IOS program from linux commandline
How to cross-compile clang/llvm for iOS?
For example, I have been trying to compile silversearcher-ag for my iPhone 6 (jailbroken). This is the project link https://github.com/ggreer/the_silver_searcher.
I am targeting iOS 12.4.
These are the commands that I`ve tried
./configure CC=/home/growtopiajaw/Desktop/cctools-port-master/usage_examples/ios_toolchain/target/bin/arm-apple-darwin11-clang CXX=/home/growtopiajaw/Desktop/cctools-port-master/usage_examples/ios_toolchain/target/bin/arm-apple-darwin11-clang++ --host=arm-apple-darwin11
make
I am using cctools-port to cross compile the project. My compiled cctools toolchain is located under /home/growtopiajaw/Desktop/cctools-port-master/usage_examples/ios_toolchain/target and below is how the toolchain`s directory structure looks like
This is my configure log: https://del.dog/nugibonury
This is my make log:
CC src/ignore.o
In file included from src/ignore.c:11:
./src/options.h:7:10: fatal error: 'pcre.h' file not found
#include <pcre.h>
^~~~~~~~
1 error generated.
make: *** [Makefile:494: src/ignore.o] Error 1
This is my GitHub repository containing the cross compile toolchain

Apple does not ship PCRE. You need to get the headers and dylib/tbd files manually.
If you're using checkra1n or unc0ver, then the deb on the APT repo contains headers as well, so you could just use that.
If you plan to package this into an APT/dpkg file, make sure to add pcre as a dependency.
I tried to augment my rust project with a dependency on jni="0.12.3" and my next cargo build failed with the following error:
error: unable to get packages from source
Caused by:

I'm running cargo built from gentoo's dev-util/cargo-0.30.0 ebuild.
Since rust is a quickly-evolving language, the latest crates seem to use new features that my older version of cargo did not support. And since rust/cargo did not have something like portage's EAPI marker, the old cargo did not have a way to figure that out, so the error message was a bit indirect.
I have a theory that the Cargo.lock could be tweaked to use an older version of the backtrace crate, but I was not able to figure out a procedure to do this.
Upgrading to the rust-1.34.2 ebuild, and (don't forget this step:) then using eselect rust set 1 activated the new version of cargo, and it was able to build the package without malfunctioning.
I tried running 'python setup.py build' to build Open SfM. I had used the instructions off the OpenCV website to build OpenCV using gitbash and Cmake in my lib folde without any errors.
However the OpenSfM build error says: Could not find a package configuration file provided by "OpenCV" with any
of the following names:
OpenCVConfig.cmake
opencv-config.cmake
I can't for the life of me find these files. I tried downloading the OpenCv package again and running it through a Cmake GUI but I get an error saying there's no CmakeLists.txt files.
Help?
You need to not just generate the files using CMake but also use either an application like VisualStudio or command line to build the files.
Once you build the files, the OpenCVConfig.cmake files are generated, which you use to point to the OpenSFM compilation.
I am trying to build this code:
https://docs.opencv.org/3.2.0/d5/d6f/tutorial_feature_flann_matcher.html
I am using Ubuntu 16.04 with CLion 2017.3 and have OpenCV 3.4 installed.
xfeatures2d.hpp can't be found on the system.
I have looked at many different problems on the internet, but couldn't find a solution.
Any help?
You have to include cmake comiplation flag to opencv OPENCV_EXTRA_MODULES_PATH and set it to the opencv_contrib/modules.
cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules
Here's what I had to do to compile OpenCV with xfeatures2d:
Download opencv_contrib (I took a release from the releases page). This step is what gives us xfeatures2d.
Unpack the tarball somewhere, e.g., ~/src/opencv_contrib-4.5.5
When configuring OpenCV (the main OpenCV source like opencv-4.5.2) with CMake, add the following option to cmake command line (adjusting the value to be your actual path to the modules subdirectory of the opencv_contrib tarball):
-DOPENCV_EXTRA_MODULES_PATH=$HOME/src/opencv_contrib-4.5.5/modules/
Now just build as you normally would and install.
The above actions gave me the expected file (among others): /usr/include/opencv4/opencv2/xfeatures2d.hpp.
