# 定位shared object 文件
n0name@xm:~$ locate libcanberra-gtk-module

# GTK (GIMP Toolkit) 是一套用于创建图形用户界面的工具包
# Ubuntu22.04安装了libcanberra-gtk3-module（gtk-3.0+），而Matlab需要调用的是gtk-2.0+的canberra动态链接库

# 操作系统版本
n0name@xm:~$ uname -a
Linux xm 5.19.0-41-generic #42~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Apr 18 17:40:00 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

# 进入/usr/lib/x86_64-linux-gnu, 发现安装的是gtk3.0+
n0name@xm:/usr/lib/x86_64-linux-gnu$ ls | grep "libcanberra*"
libcanberra-0.30
libcanberra-gtk3.so.0
libcanberra-gtk3.so.0.1.9
libcanberra-gtk.so.0
libcanberra-gtk.so.0.1.9
libcanberra.so.0
libcanberra.so.0.2.5

# 进入/usr/lib查看，发现没有canberra文件
# linux默认库是从“/usr/lib/”路径下找，而canberra动态链接库位于“/usr/lib/x86_64-linux-gnu/”路径下；

# 1. 安装gtk 2.0+的版本
sudo apt-get install libcanberra-gtk-module -y
# 2. 查看是否安装成功 查看路径：/usr/lib/x86_64-linux-gnu/gtk-2.0/modules
n0name@xm:/usr/lib/x86_64-linux-gnu/gtk-2.0/modules$ ls
libatk-bridge.so  libcanberra-gtk-module.so  libferret.so  libgail.so
n0name@xm:/usr/lib/x86_64-linux-gnu/gtk-2.0/modules$ 

# 3. 创建软链接
sudo ln -s /usr/lib/x86_64-linux-gnu/gtk-2.0/modules/libcanberra-gtk-module.so /usr/lib/libcanberra-gtk-module.so

# 以上为解决 Failed to load module "canberra-gtk-module" 问题

问题2解决

# 打开MATLAB后在命令行输入：
# 1. 查看版本
>> version

ans =

    '9.8.0.1323502 (R2020a)'
# 2. 查看安装路径
>> cd(matlabroot)
>> pwd

ans =

    '/home/n0name/software/matlab_2020a_install'
# 3. 查看问题
>> !bin/glnxa64/MATLABWindow
bin/glnxa64/MATLABWindow: symbol lookup error: /lib/x86_64-linux-gnu/libpango-1.0.so.0: undefined symbol: g_memdup2
# 4. 解决以上问题

# 在 bash terminal中
# 进入 <安装路径>/cefclient/sys/os/glnxa64
cd ~/software/matlab_2020a_install/cefclient/sys/os/glnxa64
# 创建文件夹
sudo mkdir exclude
# 移动白色的文件
