I am trying to compile itk from source, its with version 5.3. On a windows 10 64 bit machine and with mingw-w64 version 10 installed i am using cmake(latest version) to build the itk source.
How ever during build i am getting a linker error of " multiple definitions found for most of the pthread functions" coming from another source file .
As i am directly building from source and not supposed change the source files any can tell me how to avoid that error ?
I have tried with -fcommon --allow-multiple-definition linker options without any help.
Later found out that -fno-common was introduced in latest gcc versions.
also is there any way to build ITK this version with any other compiler in windows 10 ?
I have tried with windows sdk latest but that does not give me the option to generate make files through cmake. And gives a strange error of Nmake file not found even though it is a default cmake generator of windows.
Please note : I am not interested in installing visual studio . thats why cant get hold of msvc compilers.

MinGW is neither officially supported, nor tested, so it is not surprising that it doesn't work. Contributions to add support are welcome.
Microsoft offers just the command-line compiler, without needing Visual Studio. You might also have better luck with Clang for Windows than MinGW.
