这是我的makefile:
### OUTPUT ###
BUILD = Build
### SOURCES ###
SRC = Src/main\
Src/Game/Game\
Src/Shader/Shader
### OBJECTS ###
OBJ = $(addsuffix .o, $(addprefix $(BUILD)/, $(SRC)))
### INCLUDES ###
INC = -ID:/Development/OpenGL/Glfw/include/GLFW\
-ID:/Development/OpenGL/Glew/glew-2.1.0/include/GL\
-ID:/Development/OpenGL/Glm/glm-0.9.9.8/glm\
-ISrc/Game\
-ISrc/Shader/
### LIBRARIES ###
LIB = -LD:/Development/OpenGL/Glew/glew-2.1.0/lib/Release/Win32 -lglew32s\
-LD:/Development/OpenGL/Glfw/lib-mingw -lglfw3\
-lopengl32
### LINKER FLAGS ###
LFLAGS = $(LIB)
### COMPILER FLAGS
CFLAGS = $(INC)
### COMPILER ###
CC = g++
all: $(BUILD)/test.exe
$(BUILD)/test.exe: $(OBJ)
@echo LINKING $^
@$(CC) $(LFLAGS) -o $@ $^
$(BUILD)/%.o: %.cpp
@echo COMPILING $<
@mkdir -p $(subst /,\,$(dir $@))
@$(CC) $(CFLAGS) -M -MT $@ -o $(patsubst %.o, %.d, $@) $<
@$(CC) $(CFLAGS) -o $@ -c $<
-include $(OBJ:.o=.d)
.PHONY: clean
clean:
@echo CLEANING......
@@rm -rf $(BUILD)/*
我在这里指定所需的库:
### LIBRARIES ###
LIB = -LD:/Development/OpenGL/Glew/glew-2.1.0/lib/Release/Win32 -lglew32s\
-LD:/Development/OpenGL/Glfw/lib-mingw -lglfw3\
-lopengl32
并在此处链接它们:
$(BUILD)/test.exe: $(OBJ)
@echo LINKING $^
@$(CC) $(LFLAGS) -o $@ $^
我遇到的错误是:
LINKING Build/Src/main.o Build/Src/Game/Game.o Build/Src/Shader/Shader.o
Build/Src/Shader/Shader.o:Shader.cpp:(.text+0xb): undefined reference to `__glewUseProgram'

Build/Src/Shader/Shader.o:Shader.cpp:(.text+0x11c): undefined reference to `__glewCompileShader'
我也定义了GLEW_STATIC
:
#define GLEW_STATIC
#include "glew.h"
我正在使用mingw32,并且正在使用mingw32-make all
调用makefile我不知道为什么它找不到那些符号...我一直在努力弄清楚2个小时。
编辑:这是实际的链接命令:
g++ -LD:/Development/OpenGL/Glew/glew-2.1.0/lib/Release/Win32 -lglew32s -LD:/Development/OpenGL/Glfw/lib-mingw -lglfw3 -lopengl32 -o Build/test.exe Build/Src/main.o Build/Src/Game/Game.o Build/Src/Shader/Shader.o
这是我的makefile:###输出###构建=构建###源### SRC = Src / main \ Src / Game / Game \ Src / Shader / Shader ###对象### OBJ = $(addsuffix .o,$(addprefix $(BUILD)/,$(SRC)))...
在单通链接器中(与当今几乎所有链接器一样),项的顺序至关重要。特别是,必须确保所有对象文件都在链接库first
