- How to get a statically-linked libGL.so when building with make<br></blockquote><div><br></div><div>You'll need to clarify that some. libGL.so is by it's very nature a shared library so static doesn't apply there. If you mean a fully static library, i.e. libGL.a, then you--enable-static shoudl do that. However, I suspect what you actually want is to compile in the llvm libraries statically and still get a shared libGL.so. In that case, I believe --disable-llvm-shared-libs is what you're looking for. I typically use the following configuration for a bare-bones libGL.so with llvmpipe (these are the binaries we ship with ParaView):</div><div><br></div><div><span style="font-family:monospace,monospace">$ ./configure \<br></span></div><div><span style="font-family:monospace,monospace"> --prefix=<INSTALL_DIR> \<br> --enable-opengl --disable-gles1 --disable-gles2 \<br> --disable-va --disable-gbm --disable-xvmc --disable-vdpau \<br> --enable-shared-glapi \<br> --disable-dri --with-dri-drivers= \<br> --enable-llvm --disable-llvm-shared-libs \<br> --with-gallium-drivers=swrast \<br> --disable-egl --disable-gbm \<br> --disable-gallium-osmesa --enable-glx --with-platforms=x11<br></span></div><div><br></div><div>Some of those options are automatic but I like to be explicit with them so know for sure how they'll end up configuring. The end result is a libGL.so with relatively few dependencies that should be available just about everywhere at runtime:</div><div><span style="font-family:monospace,monospace"><br></span></div><div><span style="font-family:monospace,monospace">$ readelf -d libGL.so<br></span></div><div><span style="font-family:monospace,monospace">[chuck.atkins@hal9000 lib]$ readelf -d libGL.so<br><br>Dynamic section at offset 0x180aac8 contains 39 entries:<br> Tag Type Name/Value<br> 0x0000000000000001 (NEEDED) Shared library: [libX11.so.6]<br> 0x0000000000000001 (NEEDED) Shared library: [libXext.so.6]<br> 0x0000000000000001 (NEEDED) Shared library: [libxcb.so.1]<br> 0x0000000000000001 (NEEDED) Shared library: [librt.so.1]<br> 0x0000000000000001 (NEEDED) Shared library: [libdl.so.2]<br> 0x0000000000000001 (NEEDED) Shared library: [libtinfo.so.6]<br> 0x0000000000000001 (NEEDED) Shared library: [libpthread.so.0]<br> 0x0000000000000001 (NEEDED) Shared library: [libz.so.1]<br> 0x0000000000000001 (NEEDED) Shared library: [libstdc++.so.6]<br> 0x0000000000000001 (NEEDED) Shared library: [libm.so.6]<br> 0x0000000000000001 (NEEDED) Shared library: [libc.so.6]<br> 0x0000000000000001 (NEEDED) Shared library: [ld-linux-x86-64.so.2]<br> 0x0000000000000001 (NEEDED) Shared library: [libgcc_s.so.1]</span><br>...</div><div><br></div><div>I also typically build on a RHEL6 mahcine wth GCC4.9, and then the resulting binary seems to be able to work everywhere (RHEL7, Ubuntu, SLES, etc.).</div><div><br></div><div>- Chuck<br></div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
