General / Weird linking error on Fedora [not on any other linux I've tried] (Solved)

« on: March 24, 2016, 02:30:44 am »

On Fedora 23 when I try to use the native SFML libraries for my game I get the error while compiling:

[hunter@localhost Winter Wasteland]$ make
** Building the game

I am not using Codeblocks or Eclipse, just editing files and compiling through console. This worked on LInux Mint and Ubuntu but Fedora is having issues. Even if I link to a CMake build of SFML I did recently to try to fix this problem, I get the same exact error. Not sure why. Here is how I compile [Makefile]:

CXX := g++

CXXFLAGS:=-std=c++11

LIBS= -lsfml-graphics -lsfml-window -lsfml-system

all: winterwasteland

main.o: src/main.cpp
   $(CXX) -c $(CXXFLAGS) "src/main.cpp" -o src/main.o

Knife.o: src/Knife.cpp src/Knife.h
   $(CXX) -c $(CXXFLAGS) "src/Knife.cpp" -o src/Knife.o

Player.o: src/Player.cpp src/Player.h
   $(CXX) -c $(CXXFLAGS) "src/Player.cpp" -o src/Player.o

Snowpile.o: src/Snowpile.cpp src/Snowpile.h
   $(CXX) -c $(CXXFLAGS) "src/Snowpile.cpp" -o src/Snowpile.o

Tree.o: src/Tree.cpp src/Tree.h
   $(CXX) -c $(CXXFLAGS) "src/Tree.cpp" -o src/Tree.o

Weapon.o: src/Weapon.cpp src/Weapon.h
   $(CXX) -c $(CXXFLAGS) "src/Weapon.cpp" -o src/Weapon.o

winterwasteland: src/main.o src/Knife.o src/Player.o src/Snowpile.o src/Tree.o src/Weapon.o src/Snowflake.o
   @echo "** Building the game"
   $(CXX) -o WinterWasteland src/main.o src/Knife.o src/Player.o src/Snowpile.o src/Tree.o src/Weapon.o src/Snowflake.o $(CXXFLAGS) $(LIBS)

Thanks. Will provide more info if needed.
