Library dependency in C ++ in LINUX

A problem about library dependency in C ++ in LINUX-general Linux technology-Linux programming and kernel information. For details, refer to the following section. Program in SUSE, compile C ++ in eclipse3.2, and use the GCC/ICC compiler.

1. a static database named a. o has been created, including a1, a2, a3...... and other functions;

2. Create a static database B. o, B. o to use. some functions in o, B. the functions in o are b1, b2, b3 .... and so on;

3. Finally, I used B in MY project. a. the function in o cannot be found during connection. o, and an error occurs. (library a and its path are added to the project attributes)

4. In this case, if, in MY, you use a function in a. o, such as a1, and the other is exactly the same as step 3, the compilation connection is normal.

This is the dependency of database B on database a. When linking database a, it should be placed behind database B, similar to gcc-o my. o B. o. o or gcc-o my. o-lb-la

After the test, the problem is solved. In either case, add the database in order or use the functions in the dependent database in your code.
