Ich weiß, das wird wahrscheinlich eine ziemlich dumme Frage, aber nach zwei Tagen des Versuchs, ich dachte, ich würde sowieso fragen. Ich bin ziemlich neu in C++, also denke ich, dass es eine sehr einfache Lösung dafür geben wird.Command Line Verknüpfung für FMOD auf Windows, 'undefined Referenz'
Wenn ich versuche, die Beispiele in der Low-Level-Beispiele Abschnitt der FMOD-API auf der Kommandozeile zu kompilieren, bekomme ich immer 'undefined Referenz' Fehler für die FMOD Sachen. Ich weiß, es muss ein Problem mit den Bibliotheken, aber wie Sie in der Make-Datei sehen können, habe ich versucht, alles umfassen:
Im lib-Ordner des BMVg API ist:
fmod_vc.lib, fmodL_vc. lib, fmod64_vc.lib, fmodL64_vc.lib, libfmod.a, libfmodL.a
Ich benutze die neueste Version der FMOD-API auf Windows 8.1 64-Bit. Das Problem ist unabhängig vom Compiler. Ich habe GCC/Cygwin und CLANG ausprobiert. Die Fehlerausgabe wird von MinGW erzeugt. Ich glaube, ich habe überall im Netz gesucht. Die Anwser zu: C++:Undefined reference to 'FMOD:: X' funktionieren nicht für mich. Soweit ich sehen kann, gibt es in der API keine fmodex_vc.lib/fmodex64_vc.lib mehr.
CFLAGS = -m64 -c -Wall -g --std=c++11
LFLAGS = -m64 -g -Wl,-rpath=../lib
INCLUDE_PATH = -I../inc
LIBRARY_PATH = -L../lib
LIBS = -lfmod64 -lfmodL64 -lfmod64_vc -lfmodL64_vc
all: generate_tone.o common.o common_platform.o
g++ $(LFLAGS) $(LIBRARY_PATH) generate_tone.o common.o common_platform.o -o generate.exe ../lib/libfmod.a ../lib/libfmodL.a $(LIBS)
common.o: common.cpp common.h
g++ $(CFLAGS) $(INCLUDE_PATH) common.cpp -o common.o

g++ $(CFLAGS) $(INCLUDE_PATH) common_platform.cpp -o common_platform.o
generate_tone.o: generate_tone.cpp
g++ $(CFLAGS) $(INCLUDE_PATH) generate_tone.cpp -o generate_tone.o
Und hier sind die Fehlermeldungen:

Die Compilierung große Werke, tat Ich vermisse eine Bibliothek?
Haben Sie statische Bibliotheken für Fmod? Ich nehme an, fmod64 fmodL64 fmod64_vc fmodL64_vc sind DLLs? – P0W
Nein, sie sind alle statisch. fmod64.lib, fmodL64.lib usw. Ich habe keine DLLs hinzugefügt. Ich bearbeite die Frage ... –
Versucht, auch mit fmodex_vc.lib zu verlinken – P0W
