Mac下安装Mesa

下载Mesa源代码:

git clone https://gitlab.freedesktop.org/mesa/mesa.git

如果下载太慢,请参看 下载国外资源

我下载后看到的Mesa版本信息为:20.2.0-devel

接下来,开始构建。

拿到一个新的开源工程,先查看其工程目录下的README,这里面通常包含怎样构建该工程的信息。所以,

cd mesa
vim README.rst

可以看到构建命令为:

mkdir build
cd build
meson ..
sudo ninja install

尝试运行meson命令时,发现没有该命令,因为按TAB键时没有自动补全,所以安装meson:

brew install meson

开始构建,

meson ..

但是报错:

➜  build git:(master) meson ..
The Meson build system
Version: 0.53.0
Source dir: /Users/chencheng/gitlab/mesa
Build dir: /Users/chencheng/gitlab/mesa/build
Build type: native build
Program python found: YES (/usr/bin/python)
Project name: mesa
Project version: 20.2.0-devel

meson.build:21:0: ERROR: Unknown compiler(s): ['cc', 'gcc', 'clang', 'pgcc', 'icc']
The follow exceptions were encountered:
Running "pgcc --version" gave "[Errno 2] No such file or directory: 'pgcc': 'pgcc'"
Running "icc --version" gave "[Errno 2] No such file or directory: 'icc': 'icc'"

A full log can be found at /Users/chencheng/gitlab/mesa/build/meson-logs/meson-log.txt

可以看到没有找到pgcc和icc命令。需要下载安装PGI

再次构建,报错如下:

meson.build:876:2: ERROR: Problem encountered: Python (3.x) mako module >= 0.8.0 required to build mesa.

没有找到mako模块。解决办法如下:

pip3 install mako

再次构建,报错如下:

meson.build:1702:4: ERROR: Dependency "xext" not found, tried pkgconfig, framework and cmake
