In matlab R2019 on current archlinux I get the following error on executing commands:
>> cd(matlabroot)
>> ! bin/glnxa64/MATLABWindow
bin/glnxa64/MATLABWindow: symbol lookup error: /usr/lib/libpango-1.0.so.0: undefined symbol: g_unicode_script_get_type
I could not find any dexcription of this error. Only similar ones were mentioned in combination with libpango as well. Downgrading libpango did not help. Excluding a lot of libraries from the glnxa64 folders also did not work.
Also looking at the library itself via:
readelf -Ws /usr/lib/libpango-1.0.so.0 | grep g_unicode
5: 00000000 0 FUNC GLOBAL DEFAULT UND g_unicode_script_get_type
Shows that the symbol indeed does exist.
Pango installed: pango-1:1.44.5-1

Ok in the end I manage to solve it by excluding libgobect from /sys/os/glnx64
cd MATLAB/R2019a/cefclient/sys/os/glnxa64
mkdir exclude
mv libgobject* exclude

the error that was actually thrown to me was:
/usr/local/MATLAB/R2019b/bin/glnxa64/jcef_helper: symbol lookup error: /usr/lib/libpango-1.0.so.0: undefined symbol: g_ptr_array_copy
I followed this reddit thread
these are the commands I used:
mkdir $Matlab_root/cefclient/sys/os/glnxa64/0_excluded
mv $Matlab_root/cefclient/sys/os/glnxa64/libg* $Matlab_root/cefclient/sys/os/glnxa64/0_excluded
I can now view my Documentation window and the Live scripts

Hello Jan,
I'd like to point out that I experienced the same problem with R2019b and Arch (actually, Manjaro). What solved it for me was to relink the libraries listed here, i.e.
libgio-2.0.so
libglib-2.0.so
libgmodule-2.0.so
libgobject-2.0.so
libgthread-2.0.so
(remember to relink both the .so and the .so.0 files).

I am using Manjaro linux as well and running R2019b and get this error:
/usr/local/MATLAB/R2019b/bin/glnxa64/jcef_helper: symbol lookup error: /usr/lib/libpango-1.0.so.0: undefined symbol: g_ptr_array_copy
What do you mean by 'relinking' the above listed libraries? How do I go about it?

This link is for which file?
Would it be this?
ln -s /lib/x86_64-linux-gnu/libgthread-2.0.so /home/aryel/softwares/MATLAB/R2018a/cefclient/sys/os/glnxa64/libgthread-2.0.so
My matlab is installed in:
/home/aryel/softwares/MATLAB/R2018a/
