CFFI是否不加载依赖库？

本文介绍了CFFI是否不加载依赖库？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在尝试使用SBCL中的BLAS / LAPACK库（特别是尝试获取 LLA 包正在运行）。加载BLAS共享库时遇到很多麻烦；最终，我发现它无法加载其依赖库。最终我能够通过手动加载所有依赖项来加载BLAS：I am trying to use the BLAS/LAPACK libraries from SBCL (specifically trying to get the LLA package running). I was having a lot of troubles getting the BLAS shared library to load; eventually I discovered that it wasn't able to load its dependent libraries. Eventually I was able to load BLAS by loaded all of its dependencies manually:(setq cffi::*foreign-library-directories* '("C:/cygwin64/bin/" "C:/cygwin64/lib/lapack/"))(CFFI:LOAD-FOREIGN-LIBRARY "CYGWIN1.DLL")(CFFI:LOAD-FOREIGN-LIBRARY "CYGGCCC_S-SEH-1.DLL")[..etc..](CFFI:LOAD-FOREIGN-LIBRARY "CYGBLAS-0.dll")作为一种解决方法，这并不可怕，但是我不明白为什么CFFI：LOAD-FOREIGN-LIBRARY并非如此能够查找和加载依赖项本身。我做错了吗？As a workaround this isn't terrible, but I don't understand why CFFI:LOAD-FOREIGN-LIBRARY is not able to find and load the dependencies itself. Am I doing something wrong?推荐答案在您的情况下，可能不是CFFI，而是使这种情况发生的Windows DLL搜索规则。In your case it's probably not CFFI but Windows DLL search rules that make this happen. code> cygblas-0.dll 在 c：\cygwin64\lib\lapack 目录中，从同一目录，当前目录，Windows目录和 PATH 中搜索。As cygblas-0.dll is in the c:\cygwin64\lib\lapack directory, any dependencies it may have are searched from that same directory, the current directory, Windows directories, and from PATH.如果在路径中没有 c：\cygwin64\bin 时，找不到DLL。 cffi :: * foreing-library-directories * 不影响Windows功能； CFFI只需执行对 LoadLibrary 以及指向DLL的完整路径。If you do not have c:\cygwin64\bin in your path, the DLLs cannot be found. cffi::*foreing-library-directories* does not affect the Windows functionality; CFFI simply executes a call to LoadLibrary with a full path to the DLL.作为解决方案，建议您配置 PATH 包含 c：\cygwin64\bin 目录，无论如何这都是一个好主意。或者，您可以在调用 load-foreign-library 之前修改代码中的 PATH 环境变量，但是完成的方式取决于实现方式。As a solution, I suggest you configure your PATH to include the c:\cygwin64\bin directory, which is a good idea in any case. Alternatively, you could modify the PATH environment variable in your code before the call to load-foreign-library, but the way it's done is implementation dependent. 这篇关于CFFI是否不加载依赖库？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 阿里云证书，YYDS！
