OPCToolbox_VS2017.sln - LINK : fatal error LNK1104: cannot open file 'OTBD.lib'

[WaldemarCoding]

When I try to compile the OPCToolbox_VS2017.sln I get a Link Error for OTBD.lib file. I followed the _5._Compiling_the_OPC_Toolkitcore.md doc

• uncommented OTBcfg.h
• commented license hint in OTB.cpp->OTActivate, but didn't change the default license key value (it's still "!! ADD YOUR LICENSE CODE HERE !!")
• set OTBFunctions.cs to use Debug version
• set the PlatformToolset to v142

I ran VS2019 16.11.2 in UserMode and AdminMode with the same result

The VS2019 version seems to have changed somehow the behavior of the PostBuild copy event. Try the following:

1. Compile the OTB_VS2017 project
2. Manually create a folder called "lib" under "\development\core" and copy the "\development\core\src\OTB\bin\VS2017\Win32\Debug\OTBD.lib" to it.
3. Compile the OPCToolboxC++_VS2017 project

@WaldemarCoding If you can solve the issue please feel free to make a PR

[WaldemarCoding]

Manually copying the file works. I also was able to solve it by switching to xcopy. Source: StackOverflow

The PostBuild of OTB now looks like this

xcopy "$(TargetPath)" "..\..\..\bin\" /F /R /Y /I
xcopy "$(TargetDir)$(TargetName).lib" "..\..\lib\" /F /R /Y /I

instead of

copy "$(TargetPath)" ..\..\..\bin
copy "$(TargetDir)\$(TargetName).lib" ..\..\lib

Also notice that I removed the extra backslash between TargetDir and TargetName, as TargetName already contains the backslash and added quotes around the Destination.

@FischerSeb For the PR I would add VS2019 Versions of Projects and Solution:

• OPCToolboxC++_VS2019.vcxproj
• OTB_VS2019.vcxproj
• OPCToolboxNET_VS2019.csproj
• OPCToolbox_VS2019.sln
• .gitignore File (VisualStudio Setting from gitignore.io -> link)
• the build also generates this 5 files (.bin, .h, .rc), should I add them to .gitignore or just don't stage them into the PR Commit?

[FischerSeb]

VS2019 support is perfect. Please add the 5 files to the gitignore file.

Maybe you make a new release or tag? So someone can easily download the correct version. Current release is from April.
