Hi,

I am currently getting a bit desperate trying to compile the Storage Area sample plugin on Windows.

Using CMake and Visual Studio 2015, the CMake shows “MSVC compiler version = 1900” in red.

Loading and compiling the project in Visual Studio literally ends up in a zillion errors, mostly up to ‘wrong’ integer types (unknown int64\_t etc.)

Following both the main log of CMAKE during building the project and a short section of the output while compiling in Visual Studio.

Selecting Windows SDK version 10.0.10240.0 to target Windows 10.0.17134.

The C compiler identification is MSVC 19.0.24215.1

The CXX compiler identification is MSVC 19.0.24215.1

Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/x86\_amd64/cl.exe

I also took the plugin.cpp of the Area Storage plugin and compiled it seperately (just with the required headers linked) → this is working, but I get an Error 193 when starting Orthanc with the dll (64/32 bit issue?)

Could someone provide me the information in which environment (VC version, etc.) the binaries have been compiled to reproduce it? Getting a bit desperate, currently.

Thank you!

Hello,

Build instructions for Visual Studio are available in the following file:  
[https://bitbucket.org/sjodogne/orthanc/src/Orthanc-1.5.1/INSTALL](https://bitbucket.org/sjodogne/orthanc/src/Orthanc-1.5.1/INSTALL)

You have to use the “CMakeLists.txt” that is at the root of the project, i.e. the one that will also build Orthanc (_not_ those that are inside the “Plugins” folder):  
[https://bitbucket.org/sjodogne/orthanc/src/Orthanc-1.5.1/CMakeLists.txt](https://bitbucket.org/sjodogne/orthanc/src/Orthanc-1.5.1/CMakeLists.txt)

Our continuous integration servers run both Visual Studio 2008 32bit and Visual Studio 2015 64bit.

HTH,  
Sébastien-

Thank you Sébastien  
Sorry, must have overlooked that file - will get myself worked thru it now …
