[SOLVED] Problem with compiling in windows (mingw)

[roy4801]

I keep getting "undefined reference" error when compiling the example code with SFML.
I originally have 64 bit compiler on my computer, and then switched the mingw-w64 from 64 bit (x86_64) to 32 bit (i686) and get the same error message.

g++ -std=c++14 -I../thirdparty/SFML-2.5.1/include -L../thirdparty/SFML-2.5.1/lib -lsfml-graphics -lsfml-window -lsfml-system main.cpp -o main.o

You put your files after the sfml libraries when you should have put it before.
(Also the -o flag is for specifying your output file e.g. an .exe not an object file.)

So try this:

Code: [Select]

g++ -std=c++14 -I../thirdparty/SFML-2.5.1/include -L../thirdparty/SFML-2.5.1/lib main.cpp -lsfml-graphics -lsfml-window -lsfml-system  -o insert_name_here.exe
