GnuPG for Java library ant build/bug

Question

我正在努力GnuPG Java API加密/解密文件.
用Google搜索并找到了Java Wrapper GnuPG for Java,Java包装器GPGME(GnuPG Made Easy,C language library).
官方网站也将此称为Java包装器.
所以按照说明,设置ant并尝试运行ant clean release
它是抛出错误.但maven构建工作和jar文件也生成了.
运行时发生以下错误ant.

更新

我改变了Java home的GNUmakefile,现在它抛出不同的错误.似乎c library没有找到,这个API是为Unix系统编写的,似乎是通过阅读错误信息.C库丢失了什么？

任何人都可以帮我解决这个问题吗？我在哪里弄错了？

Answer 1

我重写了我的答案，因为我想创建一个完整的指南。

将 GnuPG 和 MinGW-Get 安装到不带空格的目录中。当你用!!!GUI!!!安装了MinGW后，打开mingw-get，安装这些组件：
mingw32-gcc (全部勾选) mingw32-libz (dll是最重要的)

下载并安装MSYS，这是一个用于运行 make 等命令的命令行工具包。

然后将c:\msys\1.0\bin\ （或安装它的任何位置）放在 PATH 变量的开头。重新启动 eclipse 或打开一个新的 cmd，它应该可以工作。

在 build.xml 中：第 21 行：

classpath="lib/junit-4.4.jar" added.(and the junit is in the lib dir)

在 GNUmakefile 中：第 9 行：

ALL_CFLAGS :=  -Wall -Wno-deprecated-declarations -fPIC

第 10 行：

ALL_CPPFLAGS = -D_REENTRANT -D_THREAD_SAFE -D_FILE_OFFSET_BITS=64 -DLARGEFILE_SOURCE=1 \
        -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include" -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include/win32"

第21-27行：

  JAVA_HOME := c:/WORK/x/gnu/jdk/jdk1.8.0_25
  ALL_CFLAGS +=  -mms-bitfields -Wl,--add-stdcall-alias
  ALL_CPPFLAGS += -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include/win32" -I"c:/WORK/x/gnu/jdk/jdk1.8.0_25/include" -I"c:/GNU/GnuPG/include"
  ALL_LDFLAGS :=  -s -shared -Wl,--enable-auto-import
  ALL_LIBS := -L"c:/GNU/GnuPG" -lgpgme-11
  GNUPG_LIB := $(BUILD_DIR)/gnupg-for-java.dll

第 63 行：

$(CC) $(DEBUG) $(ALL_CFLAGS) $(ALL_LDFLAGS) $^ -o "$(BUILD_DIR)/gnupg-for-java.dll" $(ALL_LIBS)

摘要：这对我有用，并将 jar 和 dll 文件输出到构建目录。我的工作目录是 c:/WORK/x，因此请替换不同的路径。不要在任何地方使用“程序文件”，正如你所看到的，我必须从那里复制所有内容。
