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.
