I'm having trouble building my project. This is my first project I've worked on that uses make, so I'm having a lot of problems with it. Here's my Makefile: CC=g++ CFLAGS=-W -Wall -pedantic LIBS=`sdl-config --cflags --libs` -lSDL_image -lSDL_gfx -lSDL_ttf character.o: character.cpp reset; $(CC) $(CFLAGS) -c character.cpp;rm *~ battle.o: battle.cpp reset; $(CC) $(CFLAGS) -c battle.cpp character.o $(LIBS); rm *~ all: battle.o character.o reset; $(CC) $(CFLAGS) battle.o character.o $(LIBS) -o battle; rm *~ I've successfully compiled character.o and battle.o, but when I try to make all, I get a bunch of undefined references errors: battle.o: In function `battle::battle()': battle.cpp:(.text+0x9ab): undefined reference to `Character::Character()' battle.o: In function `battle::battle()': battle.cpp:(.text+0xecf): undefined reference to `Character::Character()' character.o: In function `Character::~Character()': character.cpp:(.text+0xdb): undefined reference to `vtable for Character' character.o: In function `Character::~Character()': character.cpp:(.text+0xfb): undefined reference to `vtable for Character' character.o: In function `Character::Character(char*, long, long)': character.cpp:(.text+0x11b): undefined reference to `vtable for Character' character.o: In function `Character::Character(char*, long, long)': character.cpp:(.text+0x16d): undefined reference to `vtable for Character' collect2: ld returned 1 exit status rm: cannot remove `*~': No such file or directory make: *** [all] Error 1 My source code is too long to paste into an email (I should say that it would be impolite to paste all of it into this email), but the full source code, Makefile, and the errors are at http://www.espersunited.com/~michael/needhelp.txt . Please help!
