c@c:~/Downloads/myproject/cefsimple$ gcc -I/home/c/Downloads/myproject/ -lpthread -o `pkg-config --cflags gtk+-2.0` -DUSING_CEF_SHARED cefsimple_linux.cc -L/home/c/Downloads/myproject/cefsimple -lcef -lcef_dll_wrapper `pkg-config --libs gtk+-2.0`

output:

/usr/bin/ld: /tmp/ccR4GyDg.o: undefined reference to symbol 'XSetErrorHandler'
//usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line


Any input would be awesome

Did you try googling the error message? You need to link libx11.so.
