If you’re working with log4cpp in an MSYS2 environment on Windows Server 2022, you may have run into a rather perplexing error during the build process. The cryptic message indicating that ‘long long long’ is too long for GCC can be both confusing and frustrating. In this article, we’ll unpack this problem and provide you with a straightforward solution by addressing a specific line in the config-MinGW32.h file that leads to this error. We’ll walk you through the steps needed to resolve this build error efficiently, so you can get back to developing without interruptions. Additionally, I will share plans to report this issue to upstream developers to help future users avoid similar pitfalls.

Key Takeaways

• The ‘long long long’ error in log4cpp builds on Windows Server 2022 is caused by a misconfiguration in config-MinGW32.h.
• Commenting out the line that defines int64_t as __int64 resolves the build error in an MSYS2 environment.
• It’s important to report such issues to upstream developers to prevent future occurrences.

Understanding the ‘Long Long Long’ Build Error in log4cpp

Log4cpp is a widely-used library for logging in C++ applications, offering powerful features to handle logging efficiently. However, while working with log4cpp version

1.1.4rc3 in a Windows Server 2022 environment using MSYS2, developers may encounter a perplexing build error. This error stems from a peculiar message indicating that ‘long long long’ is too long for the GNU Compiler Collection (GCC). Specifically, this issue arises from the config-MinGW32.h file within the log4cpp source code. The culprit is a line that redefines int64_t as __int64, which leads to this confusion during the compilation process. To resolve this, one can simply comment out the line causing the problem. This straightforward workaround not only allows the build to proceed but also enhances compatibility with GCC. The author intends to share this solution with the upstream developers to help future users facing the same error. It’s worth mentioning that valuable insights leading to this fix were drawn from a specific blog post, underscoring the collaborative nature of software development and the importance of community resources.

Step-by-Step Guide to Fixing the Configuration Issue

To fix the configuration issue during the building of log4cpp version
1.1.4rc3 in your MSYS2 environment, follow these simple steps. First, navigate to the log4cpp source directory where the config-MinGW32.h file is located. Open this file in a text editor of your choice, such as Notepad++ or Vim. Once you’ve opened the file, look for the line that defines int64_t as __int64. This specific line is the source of the problem causing the long error message. To resolve the issue, simply place a comment symbol (//) in front of this line to disable it. Save the changes and close the file. After making this modification, run the build process again. You should find that the error no longer appears, allowing you to successfully compile log4cpp. Remember, if you continue to face issues, consulting community forums and resources, or seeking advice from experienced developers can also provide additional support.
