First, we will introduce the Link Library: The Link Library is divided into two types: Dynamic Link Library and static Link Library.
LIB is a static Link Library. It is a static link during program compilation and connection. Its file format is. lib. That is, when the program uses a static link library ,. functions in the lib file are linked to the final executable file, because all the content required by the application is copied from the library, therefore, static
shared with the system.After the dynamic link library is shared by the system, run main and the results are as follows:Using the GCC compiler to generate a static link libraryUse an example to illustrate how to generate a static link library in the GCC compilerHello.hhello.cMain.cFirst gcc–c hello.c file generation hello.oThen use HELLO.O to generate a static link library, usingAr–rc–o LIBHELLO.A hello.oOr use AR rcs–o libhello.a hello.oThen use the static link library to compile the link main.

The test scenario, TEST,LIB1,LIB2,DLL1,DLL2, is divided into the following four scenarios:1, Test->lib1->lib2LIB1 compiles its own code to the LIB2 part, only needs to lib2 the header file, implements the code for LIB2, and associates with the placeholder.When the test connection is generated, the LIB1 code implementation is included, recursively, and the code implementation of the associated LIB2 in the LIB1 is included.LIB1 and LIB2 are no longer required to run test.2, Test->lib1->dll2LIB1 co
In the masterProgramThe global variables in the dynamic link library are correct and undeniable, but this requires the dynamic library to be added when the program compiles the link, and use extern to declare the variable in the program to be used, which does not actually achieve the essential purpose of the dynamic library (to call it again when used); this is actually not a big problem, if you only use it in one process, this article mainly discusses the use of dynamic library global variables

First, install
Pip install ipython ptpython
Then use

What are the benefits?

3 methods for installing third-party libraries in Python, 3 methods for installing third-party libraries in python
[Method 1]: Use setuptools to install the python module.
First download http://peak.telecommunity.com/dist/ez_setup.py
NOTE: It is best to download a setuptools version 15.2, which contains ez_setup.
Run python ez_setup.py
D:\work\installation\setuptools-15.2\setuptools-15.2>python ez_setup.py
specify a weak link symbol, and the other object file with the link has its definition, otherwise it is specified with a system-specific default value.
Note the points:
-C is always available for C + + compiled object files. Remember that there are overloads in C + +? To differentiate between overloaded functions, the C + + compiler appends information such as function return values/parameters to the function name to form a mangle symbol, which, when listed with this option, does

Step 2: link the dynamic library to generate the execution file:

When Jia:./Jia is executed, the following error occurs:
./Jia: Error while loading shared libraries: libmyhello. So: cannot open shared object file: no such file or directory
The error message is: the dynamic link library cannot be found. The reason is that the dynamic link library is conn
