linux编译mesa,ubuntu编译安装mesa

./configure \

--prefix=/usr/local/mesa \

--enable-osmesa \

--with-gallium-drivers=swrast \

--with-dri-drivers=i965 \

--with-dri-searchpath=/usr/local/mesa/lib/dri \

--with-egl-platforms=x11,drm,wayland

make

sudo make install

#添加环境变量

LIBRARY_PATH=/usr/local/mesa/lib:$LIBRARY_PATH

LD_LIBRARY_PATH=/usr/local/mesa/lib/dri:/usr/local/mesa/lib:$LD_LIBRARY_PATH

LIBGL_DRIVERS_PATH=/usr/local/mesa/lib/dri

GBM_DRIVERS_PATH=$LIBGL_DRIVERS_PATH

PKG_CONFIG_PATH=/usr/local/mesa/lib/pkgconfig:$PKG_CONFIG_PATH

C_INCLUDE_PATH=/usr/local/mesa/include:$C_INCLUDE_PATH

CPLUS_INCLUDE_PATH=/usr/local/mesa/include:$CPLUS_INCLUDE_PATH

export PATH

export LIBRARY_PATH

export LD_LIBRARY_PATH

export GBM_DRIVERS_PATH

export PKG_CONFIG_PATH

export C_INCLUDE_PATH

export CPLUS_INCLUDE_PATH

有时候会因出现找不到dri错误，这时候把/usr/local/mesa/lib下的dir驱动放到程序要找的目录即可

一些有用的调试变量

#export MESA_DEBUG=1

#export EGL_LOG_LEVEL=debug

#export LIBGL_DEBUG=verbose

#export WAYLAND_DEBUG=1
