undefined reference to symbol '_ZN5boost6system15system_categoryEv' error

问题

I'm new to c++ rest sdk Casablanca and using it in Codelite ide.
Operating System : Arch Linux
gcc version : 6.1.1
While building the code I get the following error in debug mode:

/bin/sh -c '/usr/bin/make -j4 -e -f  Makefile'
----------Building project:[ Casa - Debug ]----------
make[1]: Entering directory '/home/vinci/Documents/CPP_Projects_Programs/Casa'

I searched this on Stackoverflow before asking and most of the answers just pointed to linking the libraries properly in project settings and I have done that as one can see in the code above but still keeps giving the error and I don't know what am i missing??

A little Help would be appreciated... Thank You

/usr/lib/libboost_system.so.1.60.0: error adding symbols: DSO missing from command line

This DSO error means that libboost_system is missing from the command line. You should also add:

-lboost_system

to your command line just like -lcpprest

回答2:

This can happen if you reference libraries in the wrong order. I have a personal library that depends on -lboost_system, but I had listed my own library after the boost library and was getting this error. I moved my personal library to the front of the list, and the error went away.
