Thank you all for your reply! By creating a symbol link i965_dri.so pointing to ilo_dri.so, I can successfully run eglinfo on drm platform and run glxgears on x11 platform. Hmm... It’s really a little tricky.

Thus (with the rename below) you'll have conflict since there'll be two identically named files - i965_dri.so > --with-egl-platforms=x11 > (you set this one to `drm` in your attempt; which platform are you > trying to use?) > If in doubt use both ...=x11,drm. There'll be a link against X libraries, although you won't need a running X instance. >> But failed when run eglinfo in mesa demos: >> GBM platform: >> gbm: failed to open any driver (search paths >> /usr/local/lib:/usr/local/lib/dri) >> gbm: Last dlopen error: /usr/local/lib/dri/i965_dri.so: cannot open >> shared object file: No such file or directory > > Make sure you actually install the .so files to one of these locations > :) > Again Ilia is spot on - in the ilo case we explicitly use the 'wrong' name (ilo_dri.so) for all the reasons he mentioned. Opt for linking/renaming the file.
