问题 {.so filename} has W+E (writable and executable) load segments. This is a security risk shared libraries with W+E load segments will not be supported in a future Android release. Please fix the library. How can this be fixed? 来源: https://stackoverflow.com/questions/40504512/android-n-warning-against-so-file-having-we-segments

Calling .SO functions from a java Class using JNI

蓝咒 提交于 2019-12-08 15:18:44
问题 I know this might seems weird, but, right now I have a .SO (Shared Object in C) and have to make use in my Android Project. Now My requirement is to call the functions that are in .SO directly in Java creating JNI wrapper for the headers in .SO . My question is what I am assuming the flow as, 1.Create JNI native methods -> then Create header file and then -> create a implementation of those methods from header file, include the .h files from .SO in local implementation and call the methods

Symbol Resolution and Dynamic Linking

↘锁芯ラ 提交于 2019-12-04 10:30:47
I have been reading about the relocation and symbol resolution process and I have a few questions on the same. So the whole process(of loading the exec) starts with exec(BA_OS) command. During exec(BA_OS) , the system retrieves a path name from the PT_INTERP segment and creates the initial process image from the interpreter file’s segments. That is, instead of using the original executable file’s segment images, the system composes a memory image for the interpreter. It then is the interpreter’s responsibility to receive control from the system and provide an environment for the application

PhpStorm not detecting php library namespace

问题 I'm using PhpStorm as current IDE. The only issue I have with it is that it can't find my php-library. I've installed this: PHP-JS. And by install, i mean generated the php-js.so file which I've loaded via php5enmod php-js . The library works: // This is a valid namespace AND classname $context = new JS\Context; $result = $context->evaluate("var x = 3; var y = 4; var z = x + y; ++z;"); // will output 8 For some (well, not that strange) reason, PhpStorm can't find the JS namespace and

Can you cimport an .so file?

家住魔仙堡 提交于 2019-12-02 02:19:46
I have an .so file called tissue-classifier.cpython-37m-x86_64-linux-gnu.so from an external library that I want to import so that I can extend it in one of my local classes. Since I am extending a class, I need to import it as an extension type using cimport and I am wondering if this is even possible. If I use a normal import statement then I will be left with a Python compiled version which cannot be used to extend a cdef class in my current file. When I try to cimport the tissue_classifier file, it gives me the error that tissue_classifier.pxd file could not be found which makes sense

I am trying to integrate React Native with my existing Android App. I am getting the following exception, when initilizing React Native Screen: java.lang.UnsatisfiedLinkError: dlopen failed: "/data/data/com.snapdeal.main/lib-main/libgnustl_shared.so" is 32-bit instead of 64-bit The App is only crashing on 64-bit devices. As per my learning so far, I've found this issue reported on React Native Repo, but the solution suggested in this thread is not helpful as I am not using any external SO library in existing App. Apart from above, I've realized another difference in library structure on the
