MESA-LOADER: failed to open iris

ref:

• libGL error: MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: 无法打开共享对象文件: 没有那个文件或目录

先是...

MESA-LOADER: failed to open iris: /usr/lib/dri/iris_dri.so: cannot open shared object file: 
No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
failed to load driver: iris
MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so: cannot open shared object file: 
No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  149 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  167
  Current serial number in output stream:  168

所以參考上面的 ref，去看 /usr/lib 下果然沒有 dri 目錄。所以把安裝位置 ln 過來...

sudo apt --reinstall install libgl1-mesa-dri
cd /usr/lib
sudo ln -s x86_64-linux-gnu/dri ./dri

然後 Error:

MESA-LOADER: failed to open iris: /home/charles/miniconda3/envs/carla/bin/../lib/libstdc++.so.6: 
version `GLIBCXX_3.4.30' not found (required by /lib/x86_64-linux-gnu/libLLVM-17.so.1) 
(search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)
failed to load driver: iris
MESA-LOADER: failed to open swrast: /home/charles/miniconda3/envs/carla/bin/../lib/libstdc++.so.6:

X Error of failed request:  BadValue (integer parameter out of range for operation)

所以看一下 conda 系統的 libstdc++.so.6 的 GLIBCXX 支援版本有：

$ strings /home/charles/miniconda3/lib/libstdc++.so.6 | grep ^GLIBCXX
GLIBCXX_3.4
GLIBCXX_3.4.1
GLIBCXX_3.4.2
GLIBCXX_3.4.3
GLIBCXX_3.4.4
GLIBCXX_3.4.5
GLIBCXX_3.4.6
...
GLIBCXX_3.4.28
GLIBCXX_3.4.29
GLIBCXX_DEBUG_MESSAGE_LENGTH
GLIBCXX_3.4.21
GLIBCXX_3.4.9
GLIBCXX_3.4.10
GLIBCXX_3.4.16
GLIBCXX_3.4.1
...
GLIBCXX_3.4.4
GLIBCXX_3.4.26

果然沒有 3.4.30

因為是 libstdc++.so.6.0.29
系統的 /usr/lib/x86-linux-gnu/libstdc++.so 是 6.0.33

所以把 /usr/lib/x86_64-linux-gnu/ 的 6.0.33 copy 到 env 的 lib，然後重新 ln libstdc++.so.6 到 libstdc++.so.6.0.33 就可以了。
