Unfortunately, whilst Ultimaker is leading the slicer market in some areas, it is falling way way way behind in others, both other manufacturer's (partly open source) slicers and genuinely open source ones. Arachne was pioneered by Cura - but now it is becoming a standard feature of other slicers and is NOT a differentiating factor. But other slicers now have functionality which is not available with Cura, and where there is no sign of it becoming standard - such as scarf seams. Every so often I get fed up with Cura and look at other free slicers (Orca/Bambu/Prusa/Slic3r for example), and I did this again recently. For now I am sticking with Cura because of the range of plugins etc., and because other slicers lag way more than Cura (for an unknown reason). But I do foresee that I might well switch away in the future. All that said, I am really unsure whether Cura would be bothered if all the free users go elsewhere - whilst we represent a powerful testing capability, we generate very little revenue, but create quite a lot of distraction and overhead in support time.

Otherwise having spent c. 6 hours trying to find a solution online, I am now completely stuck.

Also now wondering whether it is an issue of 32 / 64 bit versions. I have python 32 installed (for another project) so which versions of CMAKE etc. should I install on Windows 64?

Adding the SDK didn't make any difference.

Thanks. I had already run that with AMD64 but not 8.1, so I tried your version and it made no difference. I am adding a Visual Studio optional component for UWA (which adds a Windows SDK and rc.exe) in case that helps. But VS setup takes hours.

In case it helps here is the CMake output: d:\GitClones\Github\Cura\libArcus\build>cmake -DCMAKE_INSTALL_PREFIX=../install_dir -DPROTOBUF_SRC_ROOT_FOLDER=%PROTOBUF_SRC% -DPROTOBUF_LIBRARY=%PROTOBUF_INSTALL%/lib/libprotobuf.lib -DPROTOBUF_INCLUDE_DIR=%PROTOBUF_INSTALL%/include -DPROTOBUF_PROTOC_EXECUTABLE=%PROTOBUF_INSTALL%/bin/protoc.exe -DBUILD_EXAMPLES=OFF -DBUILD_STATIC=ON -DMSVC_STATIC_RUNTIME=ON -DCMAKE_C_COMPILER_WORKS=1 -DCMAKE_CXX_COMPILER_WORKS=1 -DCMAKE_BUILD_TYPE=Release -G "NMake Makefiles" .. -- The C compiler identification is MSVC 19.0.24215.1 -- The CXX compiler identification is MSVC 19.0.24215.1 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - failed -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - failed -- Detecting CXX compile features -- Detecting CXX compile features - failed CMake Warning (dev) at C:/Program Files/CMake/share/cmake-3.17/Modules/GNUInstallDirs.cmake:225 (message): Unable to determine default CMAKE_INSTALL_LIBDIR directory because no target architecture is known.

Actually, CMake for libCharon works fine. But NMake still fails.

I am trying to set up to run Cura from source on Windows prior to submitting code changes for Cura, however I am having quite a lot of difficulty making the Wiki instructions work. 1. Compiled Libraries Arcus, Savitar and Charon - CMake gives a "not able to compile a simple test program" error. Fixed by adding ` -DCMAKE_C_COMPILER_WORKS=1 -DCMAKE_CXX_COMPILER_WORKS=1 to the CMake line: cmake -DCMAKE_INSTALL_PREFIX=../install_dir -DPROTOBUF_SRC_ROOT_FOLDER=%PROTOBUF_SRC% -DPROTOBUF_LIBRARY=%PROTOBUF_INSTALL%/lib/libprotobuf.lib -DPROTOBUF_INCLUDE_DIR=%PROTOBUF_INSTALL%/include -DPROTOBUF_PROTOC_EXECUTABLE=%PROTOBUF_INSTALL%/bin/protoc.exe -DBUILD_EXAMPLES=OFF -DBUILD_STATIC=ON -DMSVC_STATIC_RUNTIME=ON -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER_WORKS=1 -DCMAKE_CXX_COMPILER_WORKS=1 -G "NMake Makefiles" .. 2. Compiled Libraries Arcus and Savitar - Having fixed the above, I get the following error in CMake: Unable to determine default CMAKE_INSTALL_LIBDIR directory because no target architecture is known. Please enable at least one language before including GNUInstallDirs. I have tried adding -DCMAKE_INSTALL_LIBDIR=../install_dir/lib to the CMake command and that makes the error message go away, but I am not sure whether this was the correct fix because either way I get the following error: 3. Compiled Libraries Arcus, Savitar and Charon - NMake doesn't work: NMAKE : fatal error U1064: MAKEFILE not found and no target specified Stop. I am now completely stuck - as I have not been able to determine how to fix these. P.S. I would have updated the Wiki for point 1. if I had access to do so. Note: Edited to correct that libCharon CMake works in step 2, though the others don't.
