Are you struggling with installing MADLIB on WSL - Ubuntu and encountering the error message "cannot open 'SQLCommon.m4'"? Don't worry, we're here to help you resolve this issue. In this article, we will explain why this error occurs and provide step-by-step instructions to fix it.
Understanding the Error
The error "cannot open 'SQLCommon.m4'" usually occurs when the MADLIB installation process is unable to locate the necessary file, SQLCommon.m4. This file is a part of the PostgreSQL source code and is required for MADLIB to build and install successfully.
Possible Causes
There are a few possible causes for this error:
- The PostgreSQL source code is not installed on your system.
- The PostgreSQL source code is installed, but the file SQLCommon.m4 is missing or located in the wrong directory.
- The file SQLCommon.m4 is present, but there are permission issues preventing MADLIB from accessing it.
Fixing the Error
To fix the "cannot open 'SQLCommon.m4'" error, follow these steps:
Step 1: Install PostgreSQL Source Code
If you haven't already installed the PostgreSQL source code, you need to do so. Open your terminal and run the following command:
sudo apt-get install postgresql-server-dev-all
This command will install the necessary PostgreSQL source code on your system.
Step 2: Locate SQLCommon.m4
Once the PostgreSQL source code is installed, you need to locate the SQLCommon.m4 file. By default, it should be located in the following directory:
/usr/share/postgresql/{version}/
Replace {version} with the version number of PostgreSQL installed on your system.
Step 3: Copy SQLCommon.m4
Copy the SQLCommon.m4 file to the appropriate directory where MADLIB expects to find it. Open your terminal and run the following command:
sudo cp /usr/share/postgresql/{version}/SQLCommon.m4 /usr/include/postgresql/
Again, replace {version} with the version number of PostgreSQL installed on your system.
Step 4: Set Permissions
Ensure that the SQLCommon.m4 file has the correct permissions. Run the following command in your terminal:
sudo chmod 644 /usr/include/postgresql/SQLCommon.m4
Step 5: Retry MADLIB Installation
Now that you have copied the SQLCommon.m4 file and set the correct permissions, you can retry the MADLIB installation process. Follow the instructions provided by the MADLIB documentation or the installation guide specific to your use case.
With these steps, you should be able to resolve the "cannot open 'SQLCommon.m4'" error and successfully install MADLIB on your WSL - Ubuntu system.
Encountering an error during the installation process can be frustrating, but with the right guidance, it can be resolved. In this article, we explained why the "cannot open 'SQLCommon.m4'" error occurs and provided step-by-step instructions to fix it. By following these instructions, you should now be able to install MADLIB without any issues on your WSL - Ubuntu system.
