使用Makefile创建DLL以在Windows XP(32位)和Windows 7(64位)上运行

2023年4月5日 329次阅读

我需要修改下面的makefile来创建一个将在32位
Windows和64位
Windows环境中运行的dll(SampleNew.dll).也许创建两个dll(一个用于64,一个用于32)是最好的方法.它需要使用SampleApi.dll(在下面的LIBS声明中).以下内容不会为Windows创建有效的32位dll.有关如何修改以下内容以使其工作的任何想法？

CMODE=

SWIG = swig
CC = $(PREFIX)gcc
LD = $(CC) 

OBJ_DIR = obj
AUTOGEN_DIR = ../src/java
PACKAGE_DIR = $(AUTOGEN_DIR)/com/test/sample

PACKAGE = com.test.sample

INCLUDES = -I$(JAVA_INCLUDE) \
           -I$(SAMPLE_DIR)/include \
           -I$(JDK_HOME)/include

LIB_INCLUDES = -L$(SAMPLE_DIR)/lib

LIBS = /lib/libssl.so.4 \
       /lib/libcrypto.so.4 \
       -lSampleApi \
       -lm

DIRS = $(PACKAGE_DIR) $(DIST_DIR) $(OBJ_DIR) $(AUTOGEN_DIR)

CFLAGS = $(CMODE) -Wall -fpic $(INCLUDES) -O0 -g3
SFLAGS = -java $(INCLUDES) -package $(PACKAGE) -outdir $(PACKAGE_DIR)
LDFLAGS = -shared $(LIB_INCLUDES) $(LIBS)

OBJECTS = $(OBJ_DIR)/test_wrap.o
TARGET = $(LIB_DIR)/SampleNew.dll

all: $(DIRS) $(TARGET)

%_wrap.c: %.i
    $(SWIG) $(SFLAGS) $< 

$(OBJ_DIR)/%.o: %.c
    $(CC) $(CFLAGS) -c $< -o $@

$(TARGET): $(OBJECTS)
    $(LD) $(OBJECTS) $(LDFLAGS) -o $@

$(DIRS):
    mkdir -p $@

clean:
    rm -rf $(TARGET) $(PACKAGE_DIR)/* $(TARGET) $(AUTOGEN_DIR) $(OBJ_DIR)

例外：

java.lang.UnsatisfiedLinkError c:\test\myDllFile.dll: can't load this .dll (machine code=0x101) on a IA 32-bit platform

更新Makefile：

CMODE=

SWIG = swig
PREFIX=/test/mingw/mingw32/bin/i386-mingw32-
CC = $(PREFIX)gcc
LD = $(CC) 

OBJ_DIR = obj
AUTOGEN_DIR = ../src/java
PACKAGE_DIR = $(AUTOGEN_DIR)/com/test/jni

PACKAGE = com.test.jni

INCLUDES = -I$(HEADER_FILES_DIR) # env var that points to a dir with all the .h files

LIB_INCLUDES = -L$(C_API_DIR)/lib # env var that points to a dir with the C libraries (dlls)

LIBS = -lMainApi \ # MainApi.dll
       -lm

DIRS = $(PACKAGE_DIR) $(DIST_DIR) $(OBJ_DIR) $(AUTOGEN_DIR) # DIST_DIR is passed in 

CFLAGS = $(CMODE) -Wall -fpic $(INCLUDES) -O0 -g3
SFLAGS = -java $(INCLUDES) -package $(PACKAGE) -outdir $(PACKAGE_DIR)
LDFLAGS = -shared $(LIB_INCLUDES) $(LIBS) -leay32 -lws2_32 -lrpcrt4

OBJECTS = $(OBJ_DIR)/test_wrap.o
TARGET = $(LIB_DIR)/SampleJni.dll

all: $(DIRS) $(TARGET)

%_wrap.c: %.i
    $(SWIG) $(SFLAGS) $< 

$(OBJ_DIR)/%.o: %.c
    $(CC) $(CFLAGS) -c $< -o $@

$(TARGET): $(OBJECTS)
    $(LD) $(OBJECTS) $(LDFLAGS) -o $@

$(DIRS):
    mkdir -p $@

clean:
    rm -rf $(TARGET) $(PACKAGE_DIR)/* $(TARGET) $(AUTOGEN_DIR) $(OBJ_DIR)

最佳答案 你能做的最简单的事情就是分开建造两者.例如,定义：

CFLAGS = $(CMODE) -Wall -fpic $(INCLUDES) -O0 -g3 -march=$(ARCH)
OBJ_DIR = obj-$(ARCH)
LIB_DIR = lib-$(ARCH)

.PHONY: default
default:
        $(MAKE) ARCH=i686 all
        $(MAKE) ARCH=x86_64 all

避免-m32,因为它为x86-64生成32位代码,可能使用x86中不可用的指令.
