PureData是用于声音合成的编程语言。 LibPD是围绕它的包装，因此我们可以在Java / C#/ Android等中使用补丁。
这是包含它的GitHub页面:https://github.com/libpd/libpd
现在要在Java中使用LibPD，我认为首先应该将其库导入到我的项目中，然后使用其类和方法来调用我的补丁并对其进行调整。问题是，我找不到要添加到项目中的jar文件。我是否必须“构建”某些东西以便生成jar文件？
如果有人向我解释此程序，我将不胜感激。
谢谢

解决了
jni.h问题。我的PATH指向旧的jdk，而不是更新的jdk。现在我得到这个错误:

使用32位MinGW gcc进行了测试...仍然存在相同的错误...
更新4 [6-11-2017]:
解决了问题
看来我已经设法解决了。这是我通常所做的:
1-首先，我已经安装了msys2并对其进行了彻底的安装，
MinGW32和MinGW64和make注意:如果您从旧的原始网站获得mingw32，请删除它。它不再更新，您可能会遇到依赖性问题。2-更改了路径以使用MinGW32(因此
gcc -v应该报告32位版本)3-将JAVA_HOME更改为更新的jdk目录。似乎更新Java不会自动更新环境。变量(解决了
jni header not found问题)。4-安装
git并通过libpd命令获取git(按照存储库的自述文件中的说明)5-
make clean6- make clean libpd7- make clean javalib我希望这可以帮助别人
最佳答案
libpd Github project包含(与其他源代码存储库一样)libpd的源(而不是预构建的二进制文件)。
从README
然后继续构建:
因此，只需创建libs/libpd.jar即可:
make javalib
