shared-libraries

问题 I have an Ada program that was written for a specific (embedded, multi-processor, 32-bit) architecture. I'm attempting to use this same code in a simulation on 64-bit RHEL as a shared object (since there are multiple versions and I have a requirement to choose a version at runtime). The problem I'm having is that there are several places in the code where the people who wrote it (not me...) have used Unchecked_Conversions to convert System.Addresses to 32-bit integers. Not only that, but

问题 I need to include node.h in my c++ project, I tried to build node from source code using: ./configure sudo make I got a node executable and some object files and .a files, I need to build as .so file to use it in my c++ code. I tried to build libnode, but I got cmakelists error and this is not official nodejs project. if anybody know how to build nodejs from source code as .so file will be great, a similar question in a google group but the answer is not working. 回答1: I think it is easier to

问题 I am working with Ubuntu 16.04.2 LTS. I have been following a guide How To Set Up uWSGI and Nginx to Serve Python Apps on Ubuntu 14.04. Once I have set up the virtualenv I follow the instructions: pip install uwsgi You can verify that it is now available by typing: uwsgi --version If it returns a version number, the uWSGI server is available for use. However when I do this I get: uwsgi: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or

问题 I was reading the Qt coding conventions docs and came upon the following paragraph: Anything that has a constructor or needs to run code to be initialized cannot be used as global object in library code, since it is undefined when that constructor/code will be run (on first usage, on library load, before main() or not at all ). Even if the execution time of the initializer is defined for shared libraries, you’ll get into trouble when moving that code in a plugin or if the library is compiled
