Chapter 4 :Structure From Motion build error #29

Closed Reena24 closed 10 years ago

Reena24 commented 10 years ago

Hello i have made the required changes in the code and now I am able to configure the code. I have few build error which i have no clue on how to solve as am a beginner

This post has NOT been accepted by the mailing list yet. This post was updated on Mar 04, 2014; 1:04pm. Hi I am trying to execute the code from https://github.com/MasteringOpenCV/code/tree/master/Chapter4_StructureFromMotion I have built it using cmake but i get these error

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////Is some header file missing ????? Actually i dont have a file like C:\Qt\4.8.0\lib\QtGuid4.lib but i do have qt installed it is opensource it is installed in E:\OpenCV\dep\qt\qt-everywhere-opensource-src-4.8.4 and i have also installed PCL 1.6.0 All-In-One Installer but i checked it does not have Qt 4.8.0 in the 3rd party library. What should i do

royshil commented 10 years ago

I suggest you try to use the newer version of the SfM library: https://github.com/royshil/SfM-Toy-Library It doesn't use PCL anymore and has a more streamlined build so it may be easier to use, but it has the same core SfM code.

Hi i did what u suggested of trying the new version of Sfm library : https://github.com/royshil/SfM-Toy-Library but i get compilation error when i try to build it 2>------ Build started: Project: SfMToyLibrary, Configuration: Release Win32 ------ 2>Build started 3/8/2014 7:50:20 PM. 2>InitializeBuildStatus: 2> Touching "SfMToyLibrary.dir\Release\SfMToyLibrary.unsuccessfulbuild". 2>CustomBuild: 2> All outputs are up-to-date. 2>cl : Command line error D8021: invalid numeric argument '/Wno-sign-compare' 2> 2>Build FAILED. 2> 2>Time Elapsed 00:00:00.11 3>------ Build started: Project: SfMToyUI, Configuration: Release Win32 ------ 3>Build started 3/8/2014 7:50:20 PM. 3>InitializeBuildStatus: 3> Touching "SfMToyUI.dir\Release\SfMToyUI.unsuccessfulbuild". 3>CustomBuild: 3> All outputs are up-to-date. 3>ClCompile: 3> ViewerInterface.cpp 3> sfmviewer.cpp 3> moc_ViewerInterface.cxx 3> moc_sfmviewer.cxx 3> main.cpp 3>C:\Users\Reeba\Desktop\SfM-Toy-Library-master\SfMToyLib\Distance.h(70): warning C4172: returning address of local variable or temporary 3> Generating Code... 3>LINK : fatal error LNK1181: cannot open input file 'SfMToyLib\Release\SfMToyLibrary.lib' 3> 3>Build FAILED. 3> 3>Time Elapsed 00:00:18.09 4>------ Skipped Build: Project: ALL_BUILD, Configuration: Release Win32 ------ 4>Project not selected to build for this solution configuration ========== Build: 1 succeeded, 2 failed, 0 up-to-date, 1 skipped ==========

royshil commented 10 years ago

Looks like the .lib file was not built, try to clean and re-build the project

Reena24 commented 10 years ago

I tried clean and rebuilt a lot of times but i still get the same error

Reena24 commented 10 years ago

It finally worked thankyou for your help

thbupt commented 8 years ago

@Reena24 I just have the same error：LINK : fatal error LNK1181: cannot open input file 'SfMToyLib\Release\SfMToyLibrary.lib' How did you solve it?
