Hi,

I am trying to link wxWidgets2.8.10 with other software under linux system. However, there are a lot of undefined reference errors when they are trying to link executable files. See below
Linking CXX executable ../TexGenGUI

……
I searched the previous topics and the errors look like related with compile order, but I have no idea how to fix it. Did anyone have similar experiences?

Any help will be apprecited.

I didn’t find the right solution from the Internet.
