The approach to installing steam as described here: https://www.funtoo.org/Steam is very clever. However, it doesn't describe how it applies to Optimus laptops. Or am I missing something? Can the guide for Steam be used for gaming (Optimus) laptops? Sorry, but I'm just a mere mortal trying to figure out how I can use my gaming laptop given that Funtoo is now fully 64-bit. Other things in mind: Lutris, Wine, DXVK, Vulkan, Steam proton.

I am trying to use Windows vsts in Renoise (native linux version) through Wine, using the airwave vst bridge. If I use 32 bit version of Renoise everything works perfectly but with the 64 bit version it doesn't work at all, the plugins cannot be loaded in Renoise. I have managed to get someone else to try to replicate the problem and they could not, it seems renoise is perfectly capable to load these plugins on other systems. So this has lead me to believe I am missing something on my system because 32 bit works and 64 bit doesn't. This is my wine version: 1.7.29^t{tbz2}(X alsa fontconfig gecko jpeg mono mp3 ncurses nls opengl perl png prelink realtime run-exes ssl threads truetype xml) "ABI_X86="32 64 -x32" ELIBC="glibc" My wine prefix is 64 bit but I have tried creating a 32 bit one and it makes no difference. This is the page for the bridge - https://github.com/phantom-code/airwave As far as I can see I have all the requirements for it: I have wine, as noted above. I have Qt4. I have CMake and I have GIT. The only thing I'm not sure of is the multilib-enabled toolchain. I'm not sure what this is or whether what I have is multilib enabled or not. GCC has multilib USE flag enabled. Binutils: 2.24-r3 (cxx nls zlib -multislot -multitarget -static-libs -test -vanilla) Glibc: 2.19(2.2)^s (multilib -debug -gd -hardened -nscd -profile -selinux -suid -systemtap -vanilla CROSSCOMPILE_OPTS="-headers-only") Anything else? I don't see any errors when building airwave but perhaps I'm missing something: cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE="Release" -- VSTSDK_PATH is set to /home/alex/.git_repos/airwave/vstsdk2.4 -- VST SDK headers are found in /home/alex/.git_repos/airwave/vstsdk2.4/pluginterfaces/vst2.x -- Looking for include file pthread.h -- Looking for include file pthread.h - found -- Looking for pthread_create -- Looking for pthread_create - not found -- Looking for pthread_create in pthreads -- Looking for pthread_create in pthreads - not found -- Looking for pthread_create in pthread -- Looking for pthread_create in pthread - found -- Found Threads: TRUE -- Found LibDL: /usr/lib64/libdl.so -- Looking for XOpenDisplay in /usr/lib64/libX11.so;/usr/lib64/libXext.so -- Looking for XOpenDisplay in /usr/lib64/libX11.so;/usr/lib64/libXext.so - found -- Looking for gethostbyname -- Looking for gethostbyname - found -- Looking for connect -- Looking for connect - found -- Looking for remove -- Looking for remove - found -- Looking for shmat -- Looking for shmat - found -- Looking for IceConnectionNumber in ICE -- Looking for IceConnectionNumber in ICE - found -- Found X11: /usr/lib64/libX11.so -- Looking for Q_WS_X11 -- Looking for Q_WS_X11 - found -- Looking for Q_WS_WIN -- Looking for Q_WS_WIN - not found -- Looking for Q_WS_QWS -- Looking for Q_WS_QWS - not found -- Looking for Q_WS_MAC -- Looking for Q_WS_MAC - not found -- Found Qt4: /usr/bin/qmake (found version "4.8.6") -- libmagic version: 5.21 -- Found LibMagic: /usr/lib64/libmagic.so -- Configuring done -- Generating done -- Build files have been written to: /home/alex/.git_repos/airwave/build make Scanning dependencies of target airwave-host-32 Scanning dependencies of target airwave-host-64 [ 1%] [ 3%] Building CXX object host/CMakeFiles/airwave-host-32.dir/__/common/dataport.cpp.o Building CXX object host/CMakeFiles/airwave-host-64.dir/__/common/dataport.cpp.o [ 5%] [ 7%] Building CXX object host/CMakeFiles/airwave-host-32.dir/__/common/eventsignal.cpp.o Building CXX object host/CMakeFiles/airwave-host-64.dir/__/common/eventsignal.cpp.o [ 8%] Building CXX object host/CMakeFiles/airwave-host-64.dir/__/common/logger.cpp.o [ 10%] Building CXX object host/CMakeFiles/airwave-host-32.dir/__/common/logger.cpp.o [ 12%] Building CXX object host/CMakeFiles/airwave-host-64.dir/host.cpp.o [ 14%] Building CXX object host/CMakeFiles/airwave-host-32.dir/host.cpp.o [ 15%] Building CXX object host/CMakeFiles/airwave-host-64.dir/slaveunit.cpp.o [ 17%] Building CXX object host/CMakeFiles/airwave-host-32.dir/slaveunit.cpp.o Linking CXX executable airwave-host-64 Linking CXX executable airwave-host-32 [ 21%] Built target airwave-host-64 Scanning dependencies of target airwave-plugin-32 [ 22%] Building CXX object plugin/CMakeFiles/airwave-plugin-32.dir/__/common/dataport.cpp.o [ 26%] Built target airwave-host-32 [ 28%] Building CXX object plugin/CMakeFiles/airwave-plugin-32.dir/__/common/eventsignal.cpp.o [ 29%] Building CXX object plugin/CMakeFiles/airwave-plugin-32.dir/__/common/linkmanager.cpp.o [ 31%] Building CXX object plugin/CMakeFiles/airwave-plugin-32.dir/__/common/logger.cpp.o [ 33%] Building CXX object plugin/CMakeFiles/airwave-plugin-32.dir/masterunit.cpp.o /home/alex/.git_repos/airwave/plugin/masterunit.cpp: In member function ?intptr_t Airwave::MasterUnit::dispatch(Airwave::DataPort*, int32_t, int32_t, intptr_t, void*, float)?: /home/alex/.git_repos/airwave/plugin/masterunit.cpp:331:48: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] rect_ = *reinterpret_cast<ERect*>(frame->data);

Hello, my doubt is for enable a multilib system (able to run wine, skype, ...) I just have install "emul-linux" packages?
