QUESTION

Problems installing BGSlibrary using opencv and visual studio 2019

Asked 2021-May-21 at 14:44

So I asked a similar question a week ago, and got send to a thread for linker errors. I have now read through all of the errors and did a full clean install of everything including OpenCV, all with cmake.

The problem is that I still get the same linker errors when I now add the project properly. I have built the project using cmake and added the library file to dependencies and the library destination to the library directories.

https://github.com/andrewssobral/bgslibrary/tree/master It is this library, and I followed the cmake steps as the integration steps and I am honestly just lost with what I can do now.

If someone could please explain this to me in baby steps it would be really appreciated, as I am pretty sure I did everything right and still am getting the wrong answer

Photo's of all the steps I have taken: Initial Clone, Cmake, After a succesful build on release mode. Errors after implementing 1 line of code, The implementation that brings up the error

Please I am genuinely just lost.

PS: After following Drescherjms answers I rebuild my OpenCV but this time on release mode (as they noted, the error was that it couldn't find that .lib file). This solved the problem of not finding that but added a load of new linker errors that didn't exist before this while building. I will paste a few of them here:

For people that know how to at least install libraries and set things up in Visual Studio 2019, the problem for me was that I was building different versions in different configurations.

I had OpenCV build in Debug Win32 and BgsLibrary I tried to build in Release x64. After what drescherjm said about the problem possibly lying in the OpenCV build I rebuilt OpenCV from scratch but this time in Release Win32 (as bgslibrary requires you to build in Release). After that I built bgslibrary from scratch again as well but this time also in Release Win32. After that it was just linking up all the libraries and adding the .dll locations to my path and it worked!

I want to use bgslibrary in my research using the wrapper_matlab files found in the bgslibrary folders on github.

I followed the steps mentioned in the README but I got an error when I run the compile.m.

I have installed Microsoft Visual Studio 2015 and I am working with matlab 2018a.

It looks like you might have headers for two different versions of OpenCV. This:

QUESTION

Can't find location of libopencv_core.so.3.4.0 even though program is installed and working perfectly

Asked 2018-Mar-02 at 11:47

I installed the openCV library through apt-get. I am trying to install the BGSLibrary and the cmake file tries to find " /usr/local/lib/libopencv_core.so.3.4.0" The script fails and looking manually the folder isn't there. I have tried searching for it and nothing is turning, infact nothing is turning up for openCV, apart from a folder in usr/local/share which only contains a few cmake files and folders about the haar cascade. I don't even know where openCV is installed even though it is working perfectly.

I am using python 2.7 with openCV 3.4.0

Its important to have your cMake report (outputlog file) up to the error reporting included into your question without it a black box is presented. Anyhow.. a shot for the bow below.

Look into your cMake output/log for:

CMakeFiles/Makefile2:123456: recipe for target 'modules/python2/CMakeFiles/opencv_python2.dir/all' failed.

QUESTION

Dependency errors when loading custom dll in python, built with Visual Studio 2017 and boost

Asked 2017-Jul-12 at 16:06

I am trying to build the BGSLibrary python module from C++ and boost source. The library compiles without a problem on linux. For windows I am using Visual Studio 2017 and Cmake 3.9. Here were my steps.

Visual Studio Install options
Download Boost, Install Script from within Visual Studio Command Line Terminal

bootstrap.bat

b2 -j%cores% toolset=msvc-14.1 address-model=32 architecture=x86 link=static threading=multi runtime-link=static --build-type=complete stage --with-python
1. Rename boost_python-vc141-mt-s-1_64.lib to python_boost.lib to satisfy cmake requirements.
CMake Config options
Visual Studio External Include Directories
Visual Studio External Lib Directories
Move a copy of the originally named boost_python-vc141-mt-s-1_64.lib to the bgs build folder.
Execute Visual Studio Build. It successful creates libbgs python dll
According to this question I rename libbgs.dll to .pyd and have the boost lib in the folder. I added bgslibrary/build to path. Unfortunately not quite there yet.

Some dependency issue. A quick look at DependencyWalker is very intimidating, a huge number of problems.

Before I go and try to individual add all those .dll manually to the bgslibrary/build folder, is there a higher level error that I've done. Should I have selected "static library" in the general properties of visual studio, would that make a difference?

Solved. Dependency walker is old enough where it just shows alot of errors. Really it was jut the 4 opencv dlls. Adding opencv/build/release/bin to my path did it.
