Does anyone success run this codes on Visual Studio in Windows7, I meet some problems

[ruizengalways]

First, I download the codes and unzip them to my C Drive. After that, I use CMake, VS2012, openCV 3.0 to generate the project. CMake Shows

OPENMP FOUND OPENMP FOUND Configuring done Generating done

Then I build ALL_BUILD, the project says "LNK1104 cannot open file '..\Lib\Debug\TILDE.lib'" and a lot of grammar errors due to my complier isn't compatible to C++11.

Then I immediately download VS2015 from Microsoft. and try to generate above project again by using above method again. VS only report "LNK1104 cannot open file '..\Lib\Debug\TILDE.lib'" and a lot of warnings.

I think the openCV in my desktop may be problematic. So I download openCV 2.4.11 from opencv.org and try use CMAKE to generate opencv Project. Jesus, I failed. I note that my graphic card is AMD, rather than NVIDIA. I cannot use CUDA. Then I generate the openCV project without CUDA. I succussed to build the Debug, win 32. In the following step, The TILDE project is generated by CMAKE, openCV 2.4.11, VS2015. But at last, I still get "LNK1104 cannot open file '..\Lib\Debug\TILDE.lib'".

I don't know which step of my above method is wrong? Could anyone tell me how to run this example correctly. I am a beginner in openCV, Visual Studio and C++. All my previous work is done in matlab. It really make me crazy.

Thank you for reading. Please help me.

Hi, sorry for the trouble you are having. Can you tell me the structure of your c++ directory after you run CMake? It should be something like

C++ -- CMakeLists.txt |- Demo |- Libs |- build

and everything CMake generates should be in the build directory. I suspect you set the CMake build directory to the C++ folder.

Hi Kmyid, Thank you for your kind reply. Let me describe my setup process in details.

1. I installed opencv in ‘C:\opencv’. Then I used ‘C:\opencv\source’ and CMake to build a new opencv in VS2015 in ‘C:\opencv\mybuild’
2. The CMake is installed in ‘C:\Program Files (x86)\CMake’.
3. TILDE-1.0.3.zip is unzipped to ‘C:\Users\n9544453\Documents\TILDE-1.0.3’ The directory of TILDE-1.0.3 is represented as

TILDE-1.0.3 |- C++ |- data |- matlab -- .gitgnore -- README

4. Then I open CMake. The options of CMake is shown as follows

Where is the source code: C:/Users/n9544453/Documents/TILDE-1.0.3/c++ Where to build the binaries: C:/Users/n9544453/Documents/TILDE-1.0.3/c++/build

TILDE_LIBRARY_PROJECT TILDE CMAKE_CONFIGURATION_TYPES Debug;Release;MinSizeRel;RelWithDebInfo CMAKE_INSTALL_PREFIX C:/Program Files (x86)/Lib and Demo OpenCV_DIR C:\opencv\mybuild

Now I click Configure, CMake-gui.exe says

OPENMP FOUND CMake Error at Lib/CMakeLists.txt:56 (install): install Library TARGETS given no DESTINATION!

OPENMP FOUND Configuring incomplete, errors occurred!

I searched on Internet to solve this problem and followed this solution http://stackoverflow.com/questions/14990343/cmake-error-targets-given-no-library-destination-for-shared-library-target

Then I added ARCHIVE DESTINATION ${PROJECT_SOURCE_DIR} in C:\Users\n9544453\Documents\TILDE-1.0.3\c++\Lib\CMakeLists.txt – line 56.

Repeat step 4, I get

OPENMP FOUND OPENMP FOUND Configuring done After this I click Generate button on CMake. It shows

OPENMP FOUND OPENMP FOUND Configuring done Generating done

I open ‘Lib and Demo.sln’ in ‘C:\Users\n9544453\Documents\TILDE-1.0.3\c++\build’ and click Build ALL_BUILD

At last, It shows

Code || Description || Project || File || Line Active || Command Line error – specified director C2131 || Expression did not evaluate to a constant ||TILDE || libTILDE.cpp || 261
C2131 || Expression did not evaluate to a constant ||TILDE_static || libTILDE.cpp|| 261 LNK1104|| cannot open file ‘..\Lib\Debug\TILDE.lib|| demo || LINK || 1
Undefined uint || TILDE || libTILDE.cpp|| 1320

For the first problem, I deleted TILDE-1.0.3 in my directory and use ‘C:\Users\n9544453\Documents\c++ as my new directory. It fixed.

For the second problem C2131, I modified libTILDE.cpp. I modified the code in Line 261 as follows float* pixelin1 = new float[nbChannels]; float* pixelin2 = new float[nbChannels];

and added delete [] pixelin1; delete [] pixelin2; in Line 295.

At last C2131 fixed

For the third problem, I rebuild TILDE and TILDE_static and get success. But for demo and ALL_BUILD, the problem remains in project.

Hi Again,

Sorry that you had to go through all this hassle. I pushed the change in CMakeList you did for the Lib and now that should be fine. For the pointer allocation issue, I will have to double check if it breaks anything else, but the changes seem correct. As I don't have windows and visual studio, I cannot reproduce your problem directly. I will try once I get the chance, but that would require some time. In the mean-time the demo is quite simple (just a single demo.cpp), so once you have the libraries built, you can try yourself manually at the moment.

I will update you through this issue once I have it solved.

Thanks, Kwang

Hi,

Maybe it's a bit too late, but I recently had to compile this library in windows and it worked without much trouble. I however did not use visual studio. Instead i used mingw and CMake. As mingw is basically providing gnu environment in windows, it should work :-)

I also used Qt Creator as the IDE.

Cheers, Kwang

Hi,

Thanks a lot for your efforts. I'll try compile them by mingw and Cmake ^_^

Cheers, Rui Zeng

Also,Ithink you can safely delete eigen from dependencies in cmakelists. I'll push an update Today
