Hello everyone,

first of all, I'm sorry if this is the wrong place to report this. This is my first time using Maniphest (?)

I am currently trying to compile Cycles on Windows for Windows. Doing that, I encountered ~two~ three issues

Build system was not aware of the separate Imath folder
Source files were expecting Imath headers in the root include folder instead of <Imath/*.h>
During linking, two libraries were missing: openexr/Half_s.lib and openexr/IlmImf_s.lib

Here's what I did:

Cloned the repo
Opened a "Developer Command Prompt for VS 2022" and moved into that folder
Ran "cmake -B build", moved into the build folder
Ran "cmake --build . --target install --config Release"

Now to my first issue. After generating some oso files, I get this output:

  ies.cpp
D:\git\cycles\..\lib\win64_vc15\openimageio\include\OpenImageIO/Imath.h(16,13): fatal error C1083: Cannot open include
file: 'Imath/ImathColor.h': No such file or directory [D:\git\cycles\build\src\subd\cycles_subd.vcxproj]

  murmurhash.cpp
  path.cpp
D:\git\cycles\..\lib\win64_vc15\openimageio\include\OpenImageIO/Imath.h(16,13): fatal error C1083: Cannot open include
file: 'Imath/ImathColor.h': No such file or directory [D:\git\cycles\build\src\util\cycles_util.vcxproj]
  profiling.cpp

With the fatal errors all marked red. cmake eventually finishes, though no final executable is created.

As a temporary workaround, I added the Imath folder (in my case D:\git\lib\win64_vc15\imath\include) to every directive of the affected vcxproj files (util, subd, graph, session, scene).

After fixing all this, I encountered the second error. Some source files (Alembic/Util/Foundation.h, Alembic/Abc/Foundation.h, Alembic/AbcGeom/Foundation.H) were including <Imath*.h> as well as <half.h>. However these files are located in a separate Imath/ folder inside the include folder.

So I changed the source files:

-#include <ImathVec.h>
-#include <ImathBox.h>
-#include <ImathMatrix.h>
-#include <ImathQuat.h>
-#include <ImathColor.h>
+#include <Imath/ImathVec.h>
+#include <Imath/ImathBox.h>
+#include <Imath/ImathMatrix.h>
+#include <Imath/ImathQuat.h>
+#include <Imath/ImathColor.h>

(e.g. Alembic/Abc/Foundation.h)

This resulted in another vcxproj (kernel_osl, integrator, device, ...) being unaware of the Imath folder. I also fixed this issue as described above.

With everything finally compiled, I encoutered the third issue:

  cycles_hydra.vcxproj -> D:\git\cycles\build\lib\Release\cycles_hydra.lib
  cycles_standalone.cpp
LINK : fatal error LNK1181: cannot open input file '..\..\..\..\lib\win64_vc15\openexr\lib\Half_s.lib' [D:\git\cycles\b
uild\src\hydra\hdCycles.vcxproj]
  cycles_xml.cpp
  oiio_output_driver.cpp
  Generating Code...
LINK : fatal error LNK1181: cannot open input file '..\..\..\..\lib\win64_vc15\openexr\lib\Half_s.lib' [D:\git\cycles\b
uild\src\app\cycles.vcxproj]

With the fatal errors again highlighted in red.

Now I guess these should somehow be replaced by imath/Imath_s.lib though I'm completely lost how.

Any help would be greatly appreciated! I already tried freshly cloning and building cycles, which did not fix my issues.

I would probably ask questions about building on blender.chat. I have never built cycles standalone, so I don't think I can help much. Perhaps check out https://developer.blender.org/diffusion/C/browse/master/BUILDING.md?as=remarkup if you have not yet.

Will close since this tracker is only for bugs and errors.

Thanks for the link. However, I already read that one as well as the documentation on building Blender itself. I did everything as described in these docs and still facing the issue. That's why I thought it's a bug and reported it in the first place...

I was able to confirm that this issue does not happen with the 3.1.1 release. I think some recent commits introduced it.

I'm experiencing the same issue trying to build 3.1.2 on windows - any progress?

Unsure how much progress you are expecting on an archived ticket, but i'll chime in nonetheless, you are likely trying to build cycles standalone, which only gets updated after each release against blender master libs which already has moved on to newer versions of most dependencies.

Try building against the 3.1 libs, you can grab them from https://svn.blender.org/svnroot/bf-blender/tags/blender-3.1-release/lib/win64_vc15/
