build cinecert/asdcplib to .so or .a

It looks like you're interested in building the CineCert ASDCPlib (likely related to ASDCP ---Advanced Standard Digital Content Protection) on your Ubuntu system. ASDCPlib is an open-source library used for handling content protection in digital media systems, and it appears that you're trying to build it from the source.

Here's a general guide to help you build and install CineCert ASDCPlib on Ubuntu:

Steps to Build CineCert ASDCPlib from Source

Install Dependencies

Before you can build the library, you will need to install some development tools and dependencies. These tools will allow you to compile and link the source code. Open a terminal and run:
复制代码
bash
复制代码
```
`sudo apt update
sudo apt install build-essential cmake git libssl-dev
`
```
- build-essential: Contains basic tools needed for compiling code (e.g., gcc, g++).
- cmake: Build system generator that will be used for building the library.
- git: To clone the repository if it is hosted on a platform like GitHub.
- libssl-dev: A dependency that is sometimes required by libraries dealing with content protection (for secure operations).
Clone the Repository

If the library is hosted on GitHub or another version control platform, you can clone it using git. Assuming it's hosted on GitHub, run:
复制代码
bash
复制代码
```
`git clone https://github.com/CineCert/asdcplib.git
cd asdcplib
`
```
If the repository is hosted elsewhere or you have a specific URL, make sure to replace the GitHub URL above with the correct one.
Build the Library

Once you've cloned the repository, navigate into the project folder and use cmake to set up the build environment, followed by make to compile the code.
复制代码
bash
复制代码
```
`mkdir build
cd build
cmake ..
make
`
```
- cmake ..: This tells cmake to generate the necessary files for the build system (e.g., Makefiles).
- make: This compiles the source code and generates the necessary binary files, including the static library (.a) and/or dynamic libraries (.so).
Install the Library (Optional)

If you want to install the library system-wide (so it's available for all users or projects), you can run:
复制代码
bash
复制代码
```
`sudo make install
`
```
This will copy the compiled files to standard locations like /usr/local/lib for libraries and /usr/local/include for headers.
Verify the Build

Once the build process finishes, you can verify that the static library libasdcp_x64.a has been generated by checking the build directory:
复制代码
bash
复制代码
```
`ls libasdcp_x64.a
`
```
If the library has been built successfully, you should see it in the build folder.

Additional Notes:

If asdcplib has specific build instructions or dependencies, they should be provided in the README.md or other documentation files within the repository. Be sure to check these for any special setup instructions.
If the build fails due to missing dependencies or errors during compilation, the error messages can often point you to the missing packages or issues. Feel free to share the errors, and I can help troubleshoot.

After the Build:

Once the library is built, you can use it in your projects by linking to it during the build process. If you installed it globally, the system should automatically find the library. Otherwise, you may need to specify the path to the .a file when compiling your project.

Let me know if you run into any issues while building the library, or if there's something specific about the process you need help with!
