How to compile opencv application using opencv static libs?

How to compile opencv application using opencv static libs? - c++

I compile OpenCV4 by statically link:
cmake
-DCMAKE_TOOLCHAIN_FILE=../platforms/linux/arm-gnueabi.toolchain.cmake -DCMAKE_INSTALL_PREFIX=~/opencv4-static -DBUILD_SHARED_LIBS=OFF -DBUILD_WITH_STATIC_CRT=ON -DCMAKE_BUILD_TYPE=RELEASE -DOPENCV_GENERATE_PKGCONFIG=ON ../
add the pkgconfig in the path:
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/atmark/opencv4-static/lib/pkgconfig
then compile a sample:
arm-linux-gnueabihf-g++-4.9 -std=c++11 videocapture_basic.cpp -o camera `pkg-config opencv4 --cflags --libs --static`
but got a lot of errors:

it looks like didn't link the 3rd libs.
I want a version of OpenCV libs with dependencies(libstd..) or complete static OpenCV libs.
Found something:
Looks like it's a BUG of pkg-config,
pkg-config --static not worked. so the 3rd libs didn't link.

Problem solved by disabling OpenEXR -DWITH_OPENEXR=OFF of OpenCV:

cannot compile standalone asio with exceptions turned off

I'm trying to build project which uses standalone asio as dependency. Problem is that with exceptions turned off (-fno-exceptions), I have to define throw_exception function (link to boost documentation), but no matter how I define that function, linker throws undefined reference.
This is how I've tried to define throw_exception:
#define ASIO_NO_EXCEPTIONS
#include <asio/detail/throw_exception.hpp>
template <class E>
void asio::detail::throw_exception(E const& e) {
// do something
}
I receive these linking errors:

How to properly define throw_exception function or if I'm missing something, how can these errors be solved?

You can try this, log() is the imaginary function you already use for logging ...
// somechere in a cpp file, preferably.
#include <boost/asio.hpp>
// ...
namespace boost::asio::detail {
template<>
void throw_exception(const asio::execution::bad_executor& e)
{
// throw e; // this is what the original function does
LOG("asio::execution::bad_executor thrown\n"); // etc...
exit(3); // That's all you can do at this point.
}
template<>
void throw_exception(const std::system_error& e)
{
LOG("std::system_error thrown\n"); // etc...
exit(3); // That's all you can do at this point.
}
}
You may need to declare more specializations as you go along.

I find solution. Problem was that compiler threw implementation of throw_exception from code while compiling, and when linker tried to find that function, there simply was no throw_exception. I made it like this:
namespace asio::detail {
template <typename Exception> void throw_exception(const Exception& e) {
std::cerr << "Something went wrong..." << std::endl;
std::terminate();
}
}; // namespace asio::detail
If I call this function somewhere, I don't receive linking errors. Probably, I have to implement some kind of error handling instead of that and find a solution to make this function properly compiled and linked, but, at least, I've found a reason of that strange behaviour.

C++ OpenCV 3.1.0 linking error (ubuntu)

I am a C++ newbie trying to compile some OpenCV tutorial code.
I'm running Ubuntu 16.04, and I installed OpenCV 3.1.0 with this script: https://github.com/milq/scripts-ubuntu-debian/blob/master/install-opencv.sh
The source file I'm trying to compile is here:
https://github.com/opencv/opencv/blob/master/samples/cpp/tutorial_code/calib3d/camera_calibration/camera_calibration.cpp
I wrote this makefile:
CC=g++
CFLAGS = `pkg-config --cflags opencv` -c -g
LIBS = `pkg-config --libs opencv`
all: camcalib
camcalib: camera_calibration.o
$(CC) camera_calibration.o -o camcalib
camera_calibration.o: camera_calibration.cpp
$(CC) $(CFLAGS) $(LIBS) camera_calibration.cpp
clean:
rm *o camcalib
When I "make", the camera_calibration.o object file is generated, but I get the following error during linking:
make
g++ `pkg-config --cflags opencv` -c -g `pkg-config --libs opencv` camera_calibration.cpp
g++ camera_calibration.o -o camcalib

C++ MongoDB legacy client tutorial compile error

UPDATE
Solved the issue. The was the structure of the g++ command. This one worked for me:
g++ tutorial.cpp -I/opt/local/include -I/usr/include/boost -L/opt/local/lib -lmongoclient -lboost_thread -lboost_system -lboost_regex -o tutorial
OS: Ubuntu 16.04 64-bit
Following this tutorial:
https://mongodb.github.io/mongo-cxx-driver/legacy-v1/tutorial/
I'm able to build the mongodb-client using SCons with no issue.
mongo folder of header files here:
/opt/local/include
libmongoclient.a file here:
/opt/local/lib
Code is as follows, same as the tutorial:
#include <cstdlib>
#include <iostream>
#include "mongo/client/dbclient.h" // for the driver
void run() {
mongo::DBClientConnection c;
c.connect("localhost");
}
int main() {
mongo::client::initialize();
try {
run();
std::cout << "connected ok" << std::endl;
} catch( const mongo::DBException &e ) {
std::cout << "caught " << e.what() << std::endl;
}
return EXIT_SUCCESS;
}
This is the command I'm using to compile:
g++ -I/opt/local/include -L/opt/local/lib -pthread -lmongoclient -lboost_thread -lboost_system -lboost_filesystem -lboost_program_options tutorial.cpp -o tutorial

I've searched around Google, and saw some people with the same issue, but they didn't appear to be linking files correctly. As far as I can tell I'm doing everything correctly.
Any help would be greatly appreciated.

Can someone help me please.

those are errors from the linker. so, the code compiles fine, and all the objetcs are produced, but the linker is telling you that you have used symbols (e.g., functions, class methods) which don't appear in any of the objects or files you're linking. so, you'll have to add the objects or libraries with those symbols to the list of files to be linked. the symbols you want may be in the boost binaries.

This may be a bit late for your answer. After seeing your code in the comments , i thing you are not calling the right library.
#include <boost/signals2.hpp>
#include <iostream>
void func1()
{
std::cout << "Hello world" << std::flush;
}
int main()
{
boost::signals2::signal<void ()> s;
s.connect(func1);
s();
}
you got to include signals2.hpp and not signals(though I am not very sure of it). This works just fine for me.
