LinuxViewer is work in progress.
My intention is to write an application that can connect with OpenSimulator grids and SecondLife.
On Archlinux:
sudo pacman -Syu --needed base-devel git cmake ninja
sudo pacman -Syu --needed boost sparsehash eigen systemd
sudo pacman -Syu --needed blas lapack libxml++ libxcb libxkbcommon-x11 xorgproto xcb-proto
sudo pacman -Syu --needed shaderc vulkan-headers vulkan-icd-loader vulkan-validation-layers
Note that ninja is an alternative make and is only required if you intend to configure with -GNinja (see below).
On Debian/Ubuntu:
sudo apt install build-essential autoconf pkg-config libtool gawk git cmake ninja-build
sudo apt install libboost-all-dev libsparsehash-dev libeigen3-dev libsystemd-dev
sudo apt install libblas-dev liblapack-dev libxml++2.6-dev libxcb-xkb-dev libxkbcommon-x11-dev
sudo apt install libvulkan-dev wget
Debian/Ubuntu do not have libxml++3.0, at the time of writing, but linuxviewer also supports libxml++2.6 now for that reason. It is never tested though.
Also the package shaderc does not seem to exist; it is therefore added to gitache if not found on the system.
Finally, the Vulkan SDK is not maintained by debian/ubuntu. You have to add the third-party
repository of LunarG as described here:
https://vulkan.lunarg.com/doc/view/latest/linux/getting_started_ubuntu.html
Scroll down to Install the SDK.
For example (but please check that webpage for up to date info!), for Ubuntu 20.04 (Focal Fossa) you'd do:
wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-focal.list http://packages.lunarg.com/vulkan/lunarg-vulkan-focal.list
sudo apt update
sudo apt install vulkan-sdk
Please see the above link to vulkan.lunarg.com for instructions for your Ubuntu version.
export GITACHE_ROOT=/opt/gitache_root
Where /opt/gitache_root is some (empty) directory that you
have write access to; create it if it doesn't exist yet.
It will be used to cache packages so you don't have to recompile
them (it is a 'cache', but you might want to keep it around).
git clone --recursive https://github.com/CarloWood/linuxviewer.git
cd linuxviewer
CMAKE_CONFIG=RelWithDebug # Use Debug if you are a developer.
BUILD_DIR=build
cmake -S . -B ${BUILD_DIR} -DCMAKE_BUILD_TYPE=${CMAKE_CONFIG} -DEnableDebugGlobal:BOOL=OFF
Optionally add -DCMAKE_VERBOSE_MAKEFILE:BOOL=ON to see the compile commands.
Also optionally, add -GNinja to the cmake arguments (this is what I am developing with).
Other build types are: Release, RelWithDebInfo, Debug and BetaTest.
See stackoverflow for an explanation
of the different types.
NUMBER_OF_CPUS=$((`nproc` - 2))
cmake --build ${BUILD_DIR} --config ${CMAKE_CONFIG} --parallel ${NUMBER_OF_CPUS}
Just set NUMBER_OF_CPUS to whatever you want, of course.
