1. What operating system do you have?
2. When the error occurs?

try to read through the manual, it already contains all the answers

I can quote for the future references:

Another possible error:
./SVPManager: symbol lookup error: ./SVPManager: undefined symbol: _ZN7QString13toUtf8_helperERKS_
means "installed Qt version is too old". Check that actual libQt5*.so in use are from Qt 5.5.0 or later.
If Qt 5.5 is installed into /opt, you can try something like this:
LD_LIBRARY_PATH=/opt/qt55/lib ./SVPManager

Re: [Linux] How to Fix: Undefined Symbol

I'm using Linux Mint 17.3 KDE.
I tried to run with click on the SVP icon but not work. On terminal I typed ./SVPManager and error persist. My Qt version is 5.7.
On Linux Mint 18 I was havent  problem but in mint 18 AMD not work correctly.

I tried too the all pass of the manual.

Re: [Linux] How to Fix: Undefined Symbol

Linux Mint 17.3 is based on Ubuntu 14.04 and it uses Qt 5.3 and I really doubt you have Qt 5.7 properly installed hmm
You can check which .so libs are actually in use with "ldd ./SVPManager"
