What is the LNK1107 Error?
The LNK1107 error is a linker error that occurs when the compiler is unable to find or recognize a file required for the linking process. In the context of linking MuPDF C library with Node.js addon, this error typically occurs when there’s an issue with the library files or the way they’re being linked.
Why Does the LNK1107 Error Occur?
There are several reasons why the LNK1107 error might occur when linking MuPDF C library with Node.js addon. Some of the common causes include:
- Corrupt or missing library files
- Incorrect file paths or naming conventions
- Incompatible compiler or linker versions
- Missing or incorrect dependencies
Step 1: Verify the Library Files
The first step in resolving the LNK1107 error is to verify that the MuPDF C library files are present and correct.
Download the MuPDF C library from the official website and extract the contents to a folder on your system. Make sure the folder contains the following files:
- mupdf.lib
- mupdf.h
- mupdf.c
Step 2: Check the File Paths and Naming Conventions
The next step is to ensure that the file paths and naming conventions are correct.
When linking the MuPDF C library with Node.js addon, make sure that the file paths are correctly specified in the binding.gyp file. The file path should point to the location of the mupdf.lib file.
'targets': [
{
'target_name': 'mupdf',
'sources': [ 'mupdf.c' ],
'libraries': [ '-lmupdf', '-L/path/to/mupdf/lib' ],
'include_dirs': [ '-I/path/to/mupdf/include' ]
}
]
In the above example, the file path is specified as /path/to/mupdf/lib. Make sure to replace this with the actual path to the mupdf.lib file on your system.
Step 3: Check the Compiler and Linker Versions
The compiler and linker versions can also cause compatibility issues that lead to the LNK1107 error.
Make sure that you’re using compatible versions of the compiler and linker. You can check the versions by running the following commands in your terminal:
gcc --version
ld --version
Compare the versions with the recommended versions for the MuPDF C library. If you’re using incompatible versions, update or downgrade to the recommended versions.
Step 4: Resolve Dependency Issues
Dependency issues can also cause the LNK1107 error. Make sure that all dependencies required by the MuPDF C library are installed and up-to-date.
Use the following command to install the required dependencies:
sudo apt-get install libfreetype6-dev libjpeg-dev zlib1g-dev
Step 5: Clean and Rebuild the Project
Once you’ve verified the library files, file paths, compiler and linker versions, and dependencies, it’s time to clean and rebuild the project.
Run the following command to clean the project:
node-gyp clean
Then, run the following command to rebuild the project:
node-gyp rebuild
If everything is correct, the project should rebuild successfully without any errors.
Troubleshooting Common Issues
Even after following the above steps, you might still encounter some issues. Here are some common issues and their solutions:
Issue 1: Cannot Find mupdf.lib File
Solution: Check that the mupdf.lib file is present in the correct location and that the file path is correctly specified in the binding.gyp file.
Issue 2: Incompatible Compiler Version
Solution: Update or downgrade the compiler version to the recommended version for the MuPDF C library.
Issue 3: Missing Dependencies
Solution: Install the required dependencies using the command sudo apt-get install libfreetype6-dev libjpeg-dev zlib1g-dev.
Conclusion
Resolving the LNK1107 error when linking MuPDF C library with Node.js addon requires patience and attention to detail. By following the step-by-step guide outlined in this article, you should be able to resolve the error and get your project up and running. Remember to verify the library files, check the file paths and naming conventions, ensure compatible compiler and linker versions, resolve dependency issues, and clean and rebuild the project. If you still encounter issues, refer to the troubleshooting section for common solutions.

Frequently Asked Question
Stuck with the “LNK1107: invalid or corrupt file” error while trying to link MuPDF C library with a Node.js addon? Worry not, we’ve got you covered! Here are some common questions and answers to help you resolve the issue:
What is the “LNK1107: invalid or corrupt file” error, and why does it occur?
The “LNK1107: invalid or corrupt file” error occurs when the linker is unable to find or read the object files or libraries required for linking. This can happen due to various reasons such as corrupt or missing files, incorrect file paths, or incompatible libraries.
How can I check if the MuPDF C library is correctly installed and configured?
To ensure the MuPDF C library is correctly installed and configured, first, verify that you have downloaded the correct version of the library for your system architecture (32-bit or 64-bit). Then, check that the library files (e.g., libmupdf.a or libmupdf.so) are in the correct directory and that the library path is correctly set in your system environment variables.
What are the common file paths that might cause the “LNK1107” error?
Some common file paths that might cause the “LNK1107” error include incorrect or missing paths to the MuPDF C library files, Node.js addon files, or other dependent libraries. Double-check that the file paths in your build scripts or configuration files are correct and that the files exist in those locations.
How can I troubleshoot the “LNK1107” error using build logs and compiler output?
To troubleshoot the “LNK1107” error, carefully examine the build logs and compiler output for any error messages or warnings that might indicate the cause of the issue. Look for mentions of specific files or libraries that cannot be found or accessed, and verify that those files exist and are correctly configured.
Are there any platform-specific considerations for resolving the “LNK1107” error?
Yes, platform-specific considerations can play a role in resolving the “LNK1107” error. For example, on Windows, ensure that the library files are in the correct directory and that the system environment variables are set correctly. On Linux or macOS, verify that the library paths are correctly set in the build scripts or configuration files.
