We need the same thing deploying ParaView render servers on CPU-only compute clusters without X, but I've found it difficult to really determine the right set of configuration parameters to use. With the current Mesa release, 17.x, we've settled on the following ./configure parameters to produce a bare-bones-ish libOSMesa only containing the llvmpipe software driver. Note that some of these parameters are already set by default but I find it helpful to be explicit since many of them are "auto-detect":<br> <span style="font-family:"Courier New""><br> /configure \<br> --enable-opengl --disable-gles1 --disable-gles2 \<br> --disable-va --disable-xvmc --disable-vdpau \<br> --disable-shared-glapi --disable-texture-float \<br> --enable-llvm --enable-llvm-shared-libs \<br> --with-gallium-drivers=swrast --with-platforms= \<br> --disable-dri --disable-dri3 --with-dri-drivers= \<br> --disable-egl --disable-gbm --disable-glx \<br> --disable-osmesa --enable-gallium-osmesa</span><o:p></o:p></p> </div> <p class="MsoNormal">Some that may be of specific interest to you:<o:p></o:p></p> <ul type="disc"> <li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l0 level1 lfo1"> <span style="font-family:"Courier New"">--disable-texture-float</span><o:p></o:p></li></ul> <ul type="disc"> <ul type="circle"> <li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:0in;mso-list:l0 level2 lfo1"> <span style="font-family:"Arial",sans-serif">This is disabled by default but it's an important one to be explicit with if your developing commercial software to ship.
