Hello,

I am trying install ITK. But getting following errors.  
Error 1-  
CMake Error at Modules/ThirdParty/VNL/src/vxl/config/cmake/config/VXLIntrospectionConfig.cmake:410 (message):  
Compilers that do not support RTTI are not supported

Error 2 -  
Call Stack (most recent call first):  
Modules/ThirdParty/VNL/src/vxl/CMakeLists.txt:183 (include)

Warning -  
Make Warning at CMakeLists.txt:254 (message):

I am using Visual Studio C++ compiler here.  
Kindly give me solution for this problem.  
Thanks in advance.

Hi @Pooja_Virkar,

Welcome to ITK! ☀

Did you follow the _Configuring and Building ITK_ section of the [ITK Software Guide](https://www.itk.org/ItkSoftwareGuide.pdf)?

Hello Matt,

Yes I followed the ITK software guide.  
But still I am getting those errors.  
Should I need to enable RTTI?  
But how to do it?  
And also I dont understand to solve that error 2 and warning.

Hi @Pooja_Virkar,

Run time type information (RTTI) should be available in Visual Studio by default – this indicates there is some kind of issue with the compiler / compiler recognition / compiler environment.

Please try the following:

1. Start with a clean build tree.
2. Start `cmake-gui` from a Visual Studio command prompt.

What version of Visual Studio and ITK are you using?

Hello,

I am using Microsoft Visual studio community 2017 Version 15.9.7  
& ITK version 4.13.1  
I am using Windows 10 with 64-bit O.S.  
I have one more doubt. should I use “cmake-3.14.0-rc2-win64-x64” or  
“cmake-3.14.0-rc2-win32-x86”?

I am new to the ITK.  
So Can you please elaborate what is mean by “Clean build tree”? & how to do it?  
& I am getting following message after giving cmake-gui command.

C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\>cmake-gui  
‘cmake-gui’ is not recognized as an internal or external command,  
operable program or batch file.

Please help me by guiding with steps.

Thanks.

👍 thanks for the information.

Since you have a 64 bit OS, use the 64 bit version. Try _cmake-3.13.4-win64-x64.msi_.

A clean build tree means deleting all the content of the ITK build folder, e.g. _ITK-build_.

It is OK to not start CMake from the Visual Studio command prompt; but, pick a Visual Studio CMake _generator_ during the initial configuration that corresponds to the version you have installed.

Please let us know how it goes.

Hello,

I have cleared ITK build folder. And did configuration using cmake-gui by selecting Visual studio 2017 generator.

But now I am getting following error.

```

is not able to compile a simple test program.

It fails with the following output:

See also “C:/MyProjects/ITK-bin/CMakeFiles/CMakeOutput.log”.

But then following steps helped me to remove this error.

1. Right-Click on Properties on `cl.exe` in your VS install directory (the exact path appears in the CMake error);
2. Choose the Compatibility Tab;
3. Check “Run this program as administrator” in the “Privilege Level” box.

**After that I again configured it, but now I got following errors.**

Windows has path length issues, so it is recommended to install CMake into a shorter path, e.g. _C:\CMake_ or the standard _C:\Program Files\CMake_.

> Microsoft (R) C/C++ Optimizing Compiler Version 19.16.27027.1 for x86

This is for a 32-bit build. Unless there is a specific reason for a 32-bit build, a 64-bit build is recommended.

There seems to be something wrong with your Visual Studio installation. Try “repairing” your installation: from Visual Studio Installer click “More”, then “Repair”.

Probably not related, but might be worth checking is disappearance of `rc.exe` from [VS2015 installation](https://stackoverflow.com/questions/43847542/rc-exe-no-longer-found-in-vs-2015-command-prompt).
