Question

我正在GnuPG Java API加密/解密文件用Google搜索并找到了一个Java Wrapper GnuPG for Java，GPGME(GnuPG Made Easy,C language library)的Java包装器官方网站还将this称为Java包装器按照说明操作，设置ant并尝试运行ant clean release
这是在抛出错误。但maven构建工作和jar文件也生成运行ant时发生以下错误。

更新

我更改了Java home中的GNUmakefile，现在它抛出了不同的错误。似乎没有找到c library，并且这个API是为Unix系统编写的，似乎是通过阅读错误消息。 C库丢失了什么？

有人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安装到没有空格的目录中。用!!! GUI !!!安装MinGW后，打开mingw-get，安装这些组件：
mingw32-gcc（全部查看） mingw32-libz（dll是最重要的）

Download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)

总结：这对我有用，并将jar和dll文件输出到build目录。我的工作目录是c：/ WORK / x，所以替换它不同的路径。不要在任何地方使用“程序文件”，因为你可以看到我必须从那里复制所有内容。

Answer 2

错误消息告诉我<select ng-model="selectedValue" > <option ng-repeat="deviceEach in devices" id="{{deviceEach.id}}">{{deviceEach.name}}</option> </select>找不到mingw32-gcc。

您应首先安装mingw并将其添加到您的路径中。检查是否可以从命令行启动mingw32-gcc。

您是否正在运行cygwin的ant脚本？它引用/bin/sh有点奇怪。也许你应该尝试从cygwin运行它。或者检查build.xml文件以查看如何调用mingw32-gcc。它必须是重新编译的代码目标。
