For how to use scons to build a project, refer to quickly build C ++ project tool scons and build a development environment with editplus.
When the sharedlibrary project is compiled, Lib is automatically added when the so file is produced. For example:
env = Environment()env.SharedLibrary(‘hello‘, sources=[‘hello.c‘])
Save the above as build. py and execute the compilation command
scons -f build.py
The file name libhello. So of the dynamic libra
Generally, we define global variables in the global scope to perform data interaction between modules (between functions and between classes. But be careful when doing this in Lib. If this Lib is linked by two or more DLL (including exe) And they call the same global variable in Lib, then the disaster is very likely to happen. For DLL, the link to
This problem may occur because another program is running, causing the resource to be locked out of service. The reason that the resource was locked may have been the last time that the installation was not completed properly, causing this condition to occur.Workaround: Enter the following commandsudo rm/var/cache/apt/archives/locksudo rm/var/lib/dpkg/lockAfter installing the package you want to install, you can solveWhile playing Ubuntu today, when u

First, what is Lib library. A Lib library is a file that provides specific functionality. You can think of it a
Json-lib (Maven)The mainstream tools used to interpret JSON in Java are Org.json, Json-lib, and Gson. This article describes json-lib.To use the Json-lib in the project, add the following in the Pom.xml file:When Maven install is always said to be unable to find this jar, then download the jar package on http://json-lib.sourceforge.net/:Put it in the following di
In the past two days, I have been reading the opencv tutorial-basics article. In order to adapt to the development environment in the book, although the CV has already come out of Version 2.1, I decided to run it on the platform 1.0.
During debugging, it is found that some examples cannot be compiled and the prompt is: The cvaux. Lib file cannot be found. However, the library file has been added during the setting, and is not found in the/
Lua provides source code for compilation by users. You can compile it into a static library or a dynamic library. However, Lua does not provide engineering files and needs to be added by the user. This is inconvenient for new users.
I. Lua static library
Compiling to a static library is simple. Someone has already written it. The following is an excerpt:
Lua includes core lib and standard Lib. For
First, we understand three concepts:
1.
Static Link Library
This is a noun. Lib library.
2.
Static Link
In the link item set in the project, add the. Lib library to be linked. The program contains the header file corresponding to the export function. During the compilation, the functions in the static library used will be compiled into the target file together. The target file can be the
Generally, Lua. Lib is not used. How does it come from? It is actually very simple.
We all know that Lua is cross-platform and open-source. So we can see a lot of internal code, so as to provide convenience for Lib.
Let's explain the answer. Lua. lib can be automatically generated.
Below are detailed steps:
1. The VC project, Win32 static library, is named Lua.
Ta-lib is a technical analysis library that contains most of the mainstream technical indicators, allowing users to no longer have to reinvent the wheel.This library is very common in foreign countries, a variety of large-scale open-source quantitative framework, will be built into this library.Fast calculation speedOne feature of Ta-lib is that it is computationally fast because the original version was wr
This article is original. repost the famous source.This article explains how to configure Project Association in the workspace of xcode4, but this is not the only method.
Create a workspace, add an iOS lib project called LIBA, add an iOS lib project called libb, and then add an app project called APPC.
Scenario: the APPC project uses the libs generated by the LIBA and libb projects.

Currently, the common platform written by client/server side requires plug-ins. Each plug-in is hosted in a dynamic library. In Symbian, dynamic calling is not very convenient, now let's summarize the loading methods of various types of libraries.

How to add a lib library file to the VC. Net project
In the vc6 integrated development environment, you can click the project/setting menu command to bring up the project Properties dialog box. In the activity configuration, select link/Object/library modules to enter the Lib library file to be added.
However, in the integrated development environment of VC. Net:

After the program is compiled successfully, the runtime error occurs: Error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: no such file or directory
Solution: open-source libraries such as libevent can be found in the/usr/local/lib directory after compilation and installation: # whereis libevent- 2.0 . so. 5 Libevent-2.0.so:/usr/local/lib/libevent-2.0.so.5
How to Use the jar package under lib in the idea maven Project
In project development, maven is generally used to manage projects, but sometimes the jar package under local lib needs to be referenced.
For example, the central repository does not have a jar package. In this case, we need to introduce the jar package under lib.
1. First add the local jar package
