我正在创建一个c ++动态库,用于java中的本机类 我使用javah.exe为该类生成了一个头文件,并为它创建了c接口类,但是当我尝试编译文件或构建项目时,我收到以下错误

尚未定义某些数据类型,如jlong,int64,int32 我正在使用netbeans来编译这个库 我陷入了困境 plzz帮助任何人?
答案 0 :(得分:1)
对于任何偶然发现此问题的人,根本问题是JNICALL
未定义。有关更多信息,请参见this answer。
为我解决了这一问题,方法是将#define JNICALL __stdcall
添加到jni_md.h
文件中,该文件可以在$JAVA_HOME/include/<platform>
中找到。 (对我来说, platform 是win32)
