@NickTaylor @jake rice 😮 Here are my 10 easy steps to get HDK (h17) compiling on windows 10! Before we start let me just says its 1 step on linux and mac… Also if anyone knows a better way please tell me… Anyway…. Step 1. Download Cgwin64 (bash for windows) you will need this to compile with hcustom. Step 2. h17 is compiled using VC v141. (It actually tells right in the name of the Houdini download .exe) so you will need to download visual studios and visual studios installer 2017 and download the C++ components. Step 3. Check that you actually have the files at the directory path “C:Program Files (x86)Microsoft Visual Studio2017CommunityVC” Step 3: Launch a Cgwin64 shell. Step 4. cd into your Houdini installation directory. (your build might be a different version) cd “C:Program FilesSide Effects SoftwareHoudini 17.0.352” Step 5. Source the Houdini environment. source houdini_setup Step 6. Create a MSVCDir env variable so Houdini knows where to look for the C++ components. (Your exact version may be different so make sure you check in the ”MSVC” directory) export MSVCDir=”C:Program Files (x86)Microsoft Visual Studio2017CommunityVCToolsMSVC14.16.27023” Step 7. cd into the directory your code is in. Step 8. After like 8 hour of fiddling, and if you haven’t lost the will to live, finally compile your code! hcustom.exe file.h file.cpp Step 9. Move your plugin from the Cgwin64 environment to your regular windows environment. cp “C:/cygwin64/home/USERNAME~1/houdini17.0/dsomyPlugin.dll” “C:UsersUSERNAMEDocumentshoudini17.0dso” Step 10. Launch Houdini normally and use your plug-in!
