How can I fix a build error?

VS2019 is in use, and you are trying to build VTK-9.0.1 with Cmake.

The following error occurs when Cmake is run:

How should I handle this?

Hi, this worked for me:

9.0.0.rc1 ContextOpenGL2 not built

Hm okay. I just tested with curl -LO https://www.vtk.org/files/release/9.0/VTK-9.0.1.tar.gz tar xf VTK-9.0.1.tar.gz cd VTK-9.0.1/ mkdir build cd build cmake -DVTK_MODULE_ENABLE_VTK_RenderingContextOpenGL2=YES .. and I’m not getting that warning here. Full transcript here: transcript.txt (30.0 KB) Maybe it has something to with what groups/modules get enabled by default on your system. Would help to see the output from the CMake run.

Thank you. Saeed.

I read a your transcript.txt.
but i don’t know this problem.

when i input the command( cmake -DVTK_MODULE_ENABLE_VTK_RenderingContextOpenGL2=YES …) , I received the message (this message is below that)

CMake Error: The source directory “D:/VTK/VTK-9.0.1” does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

How to solve the this problem??

[SArbabi (Saeed)]

check why CMakeLists.txt doesn’t exist in folder D:/VTK/VTK-9.0.1

Thank you, Saeed.

I checked the path and then trying the your’s command.
but i still have a problem.

this is my error and output log… CMakeError.log (29.7 KB) CMakeOutput.log (26.5 KB)

Thank you for taking the time to help me.

Looking at your first screenshot, I am surprised that CMake seems to find pthread.h while you are targetting a Windows build with VS2019 (pthread is a POSIX API for threads that is not natively supported by Microsoft). Is it expected? You might want to find this header and make sure CMake can’t find it and guess you are using a POSIX environment.
