Hell @Axel,
That is true. Traditionally /usr/local is not a user-writable directory. However, in my case I have made it as such so that I have full permissions to write in it as a user so that I do not have use sudo or su.
If I do ls -l /usr/local/build_root/lib/libvectorDict.so there is no such file. However, I do find this file:
ls -l /usr/local/build_root/lib/libvectorDict.rootmap -rw-rw-r-- 1 uzairlatif uzairlatif 427 Nov 10 12:49 /usr/local/build_root/lib/libvectorDict.rootmap
I would like to add that I did find this other post for a user who had a similar problem: Error with libvectorDict.so
However, the binary pointed out there was for GCC 9.2 and I have GCC 9.3.
