Installing gcc on Windows for Go
I see... Cgo packages need gcc
2 min read
I am recently learning Go and I stumbled upon an error about
exec: "gcc": executable file not found in %PATH% when using the
github.com/mattn/go-sqlite3 package. The package I am installing is a Cgo package which calls C code directly in Go. It requires
gcc to be installed. Indeed, I did not have
gcc installed on my Windows machine.
Pre-compiled native binaries of
gcc for Windows are not available. We have to rely on an intermediary such as Cygwin and MinGW. Luckily, MSYS2 makes this process easy for us. After installing it, you are presented with a UCRT64 terminal.
Within the terminal, install
mingw-w64-x86_64-gcc using the
pacman package manager, like so:
$ pacman -S mingw-w64-x86_64-gcc
This will install the native Windows executables of
gcc. Afterward, add
C:\msys64\mingw64\bin to your
PATH environment variable so that
gcc can be executed from anywhere on your machine.
My Go program was successfully compiled after doing the steps above. Awesome!
This short article is based on a similar and comprehensive article for C/C++ development.
The issues that I encountered would have been immediately resolved if my main operating system was running on Linux. Even more so, I would not have to rely on an intermediary tool to run
gcc on my machine. I am looking forward to making the complete switch to Linux anytime soon 🤔.
