<br>Hello,<br><br>Thanks a lot for you two! I've found my mistakes based on your tips. It is true that I missed the khrplatform.h file. I put it in the same directory of other EGL header files with the name of "EGL", so it can not be found by the program. Creating a KHR dir and putting khrplatform.h into it solved my problem. Now my paraview can work with EGL. Thank you very much!<br><br>Sincerely<br>-Zhang<br><br><blockquote name="replyContent" style="padding-left:5px;margin-left:5px;border-left:#b6b6b6 2px solid;margin-right:0">-----原始邮件-----<br>

But I don't know where the KHR/khrplatform.h is used. When I configure paraview using ccmake, the options about EGL are EGL_INCLUDE_DIR,<br>EGL_LIBRARY, EGL_gldispatch_LIBRARY, EGL_opengl_LIBRARY, VTK_EGL_DEVICE_INDEX and VTK_USE_OFFSCREEN_EGL. In the path that I assigned to the EGL_INCLUDE_DIR, there is khrplatform.h file. What's more, I have built ParaView 5.2.0 with EGL used on another machine. That machine use NVIDIA GT 730 GPU, and in the EGL_INCLUDE_DIR path, there is not a khrplatform.h file, but the paraview can be built successfully and works. The khrplatform.h is required by the current EGL (1.5), but my EGL version is 1.4. Maybe it doesn't need that file?<br><br>Thank you again!<br><br>-Zhang<br><blockquote name="replyContent" style="padding-left:5px;margin-left:5px;border-left:#b6b6b6 2px solid;margin-right:0">-----原始邮件-----<br>
