The complete process of using OpenSSL in Linux Eclipse-with screenshots and test programs

I. Installation

First download the original opensslfile, such as openssl-1.0.1f.tar.gz

Copy the file to the workspace Directory, which is generally a personal folder under/home.

Decompress the file tar zxvf openssl-1.0.1f.tar.gz

Enter the cd openssl-1.0.1f in the file

Configuration: copy the generated openssL file to the default system folder. In this step, you only need to copy the following code: "./config -- prefix =/usr/local/openssl shared"

Run the make command: make

Use root permission to install openssL: sudo make install

So far, openssL installation is complete. Two of the completed directories are important. One is the include package, which can be viewed during external calls. h header file. The other is the lib package, which contains static and shared file packages for ssl and crypto. The second step is to configure these two files.

2. How to configure in eclipse

The include and lib variables must be configured in eclipse.

Create a C language test project, such as openssL_test, right-click the attribute-C/C ++ Build-settings, and click the first red box on the right of the graph, that is, include under gcc c Compiler, make the following settings. The path here is the include position above.

Click libraries under gcc c Linker and make the following settings:

Ssl and crypto are manually added, but they are not arbitrarily written. In fact, these two variables correspond to libssl under the/usr/local/openssl/lib directory. so and libcrypto. so file.

In addition, if the project is of the C ++ type, there will be a G ++ compiler setting option, which can be set in the same way as that of GCC.
