Good catch. The sync of svn maintenance branch with GitHub is not automated. Should be good now.

I deleted the SimpleITK folders from my C:/S4D directory, fetched the latest from Slicer master-410 branch, configured the cmake project again in Cmake GUI and built again. SimpleITK began building correctly and the project has now officially built successfully. 🎉
@jcfr [https://github.com/Slicer/Slicer/commit/ebce522e0cb99a5e312800c6f01bc49e237942da](https://github.com/Slicer/Slicer/commit/ebce522e0cb99a5e312800c6f01bc49e237942da) Works well in the master-410 branch. I did notice that the comment for the tag line is incorrect. Technically
```auto
"e52c9ab047b514ef9584fef475e0ed416ad8fa4a" # slicer-v1.2.0-2019-02-27-dc5c1a1 (based of v1.1.0 tag)
```
should be
```auto
"e52c9ab047b514ef9584fef475e0ed416ad8fa4a" # slicer-v1.1.0-2018-03-21-dbc8dfe (based of v1.1.0 tag)
```
but not a big deal.

Thanks for reporting. This is now fixed.

@Saima Please read and follow the build instructions carefully (see [https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build\_Instructions#Common\_Prerequisites\_2](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_Instructions#Common_Prerequisites_2)).
You have to use Qt 5.10.X or earlier, such as 5.9 series, when building Slicer on Windows. You mixed Qt Webengine for MSVC 2017 with MSVC 2015 which is what you specified when you set “v140” as the toolset. That refers to building as MSVC 2015 even though you might be using the Visual Studio 2017 IDE.

I downloaded the slicer using the following on git cmd:
svn co [http://svn.slicer.org/Slicer4/branches/Slicer-4-10](http://svn.slicer.org/Slicer4/branches/Slicer-4-10) Slicer-r28257 -r 28257
cmake 3.15 with visual studio 15 2017 and v140 and x64
qt 5.10.0 with msvc 2015 x64
I am runing into lot of build errors.
What am I missing.
Please help me in building the slicer. I am following all the things dont know what I am missing.

Please try to build the latest trunk version of Slicer in source folder C:\D\S4, binary folder C:\D\S4D by specifying all parameters via command-line arguments (as described in “Alternative option” section [here](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_Instructions#Windows_2)).

If you checkout the repository using either SVN or git, you will get the latest version of the main branch by default. You need this version. The main branch is called “trunk” according to SVN terminology and “master” according to git terminology.

Hi Andras,
I used the latest trunk version of slicer. downloaded as:
svn co [GitHub - NA-MIC/svn.slicer.org-Slicer4: Archive of source code originally available at svn.slicer.org/Slicer4](http://svn.slicer.org/Slicer4/trunk)
I am getting no errors this time but getting alot of warnings.
Is this because I didnt run it using the command prompt.

In a software application that is built from many libraries in several different build environments, it is usually not practically feasible to eliminate build warnings (especially when they are in external libraries). You can ignore the warnings.

how to build in debug mode. Should I just change the mode in the visual studio to debug and then do build\_all

You can use the same source code folder (C:\D\S4) but you need to create a completely separate build tree for debug-mode and release-mode builds.
