Backend DevelopmentGolangHow to Resolve the 'Cgo: sorry, unimplemented: 64-bit mode not compiled in' Error?
Error: "Cgo: sorry, unimplemented: 64-bit mode not compiled in"
This error occurs when using Cgo, a package that allows Go to interact with C code, in a 64-bit operating system where the compiler used to compile the Go code does not support 64-bit mode.
Resolution:
The resolution to this issue is to ensure that the compiler used to compile the Go code supports 64-bit mode. Here are some suggestions:
-
Install a 64-bit compiler: If you are using a 32-bit compiler, install a 64-bit version.
- For example, on Windows, you can install the TDM64-GCC compiler from the MinGW-w64 project.
-
Set the CGO_CFLAGS environment variable: If you are using a compiler that does support 64-bit mode, but the error persists, you can try setting the CGO_CFLAGS environment variable to the flags that enable 64-bit mode.
- For GCC, this flag would be -m64.
- Check the compiler version: Ensure that the version of the compiler you are using supports 64-bit mode.
- Verify your environment: Use the where gcc (Windows) or which gcc (Linux) command to check the path to the compiler. If there are multiple versions of gcc installed, make sure the one you want to use is at the top of the path.
Additional Notes:
- TDM64-GCC is a recommended compiler for 64-bit Windows OS, as it provides a complete toolchain that includes both GCC and the headers and libraries needed for Cgo.
- MinGW-w64 is another viable compiler that supports 64-bit mode. However, it may require additional steps for setting up the development environment.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
