<!--第一次生成javacpp 文件的時候，skip 一定要設置為false ，后期對于生成的類進行了處理之后，為了避免每次運行都重啟，可以把skip 設置為true--><configuration> <skip>false</skip> <outputDirectory>${project.build.sourceDirectory}</outputDirectory> <classOrPackageName>com.jacdong.preset.* </classOrPackageName></configuration> |

@Properties(target = "com.jacdong.wrapper.JavaCPPTestTmp",value = {@Platform(include = {"javacpp.h"}, compiler = "cpp11")})public class JavacppMapper implements InfoMapper{ public void map(InfoMap infoMap) { infoMap.put(new Info().cppNames("_stdcall").skip()) .put();}} |
注意點
在利用javacpp 的時候，經常會出現找不到so 文件的情況，這個時候，大家可以把so 文件copy 到/usr/lib 目錄下，然后更改相應的權限。
到此這篇關于Java利用JavaCPP調用算法示例的文章就介紹到這了,更多相關Java JavaCPP調用內容請搜索服務器之家以前的文章或繼續瀏覽下面的相關文章希望大家以后多多支持服務器之家！
