Only the symbols had used in the left side of the library will be defined.` `See` `"man GCC"` `for more information` ## Example: ### Error ```SHELL g++ $(shell wx-config --libs) -lwx_gtk3u_richtext-3.1 -lwx_baseu_xml-3.1 ... ``` ### Correct ```SHELL g++ -lwx_gtk3u_richtext-3.1 -lwx_baseu_xml-3.1 $(shell wx-config --libs) ... ``` ###### tags: `gcc` `g++` `linker`
