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>

It's said that EGL is a pretty good choice for this situation, but as I switch VTK_USE_OFFSCREEN and VTK_USE_OFFSCREEN_EGL to "ON" and then make, I get these errors:<br><br>Built target vtkIOImage<br>[ 16%] Building C object VTK/ThirdParty/glew/vtkglew/CM<wbr>akeFiles/vtkglew.dir/src/glew.<wbr>c.o<br>In file included from /pan20/yzzhang/EGL/egl.h:39,<br> from /pan20/yzzhang/ParaView-v5.2.0<wbr>/VTK/ThirdParty/glew/vtkglew/s<wbr>rc/glew.c:38:<br>/pan20/yzzhang/EGL/eglplatform<wbr>.h:37:29: error: KHR/khrplatform.h: No such file or directory<br>In file included from /pan20/yzzhang/EGL/egl.h:39,<br> from /pan20/yzzhang/ParaView-v5.2.0<wbr>/VTK/ThirdParty/glew/vtkglew/s<wbr>rc/glew.c:38:<br>/pan20/yzzhang/EGL/eglplatform<wbr>.h:151: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘EGLint’<br>In file included from /pan20/yzzhang/ParaView-v5.2.0<wbr>/VTK/ThirdParty/glew/vtkglew/s<wbr>rc/glew.c:38:<br>/pan20/yzzhang/EGL/egl.h:121: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘EGLBoolean’<br>In file included from /pan20/yzzhang/ParaView-v5.2.0<wbr>/VTK/ThirdParty/glew/vtkglew/s<wbr>rc/glew.c:38:<br>/pan20/yzzhang/EGL/egl.h:122: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘EGLBoolean’<br>/pan20/yzzhang/EGL/egl.h:123: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘EGLContext’<br>/pan20/yzzhang/EGL/egl.h:124: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘EGLSurface’<br>/pan20/yzzhang/EGL/egl.h:125: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘EGLSurface’<br>......<br><br>Maybe it is clear that there is something wrong with the EGL header file, but I don't know how to fix it.
