Each additional platform (with a different operating system to the current one) will require a C compiler to be installed. The ones recommended throughout this book are as follows (along with the CC environment variable to use them with CGo):
| Target Platform | CC= | Download | Notes |
|
macOS (darwin) |
o32-clang |
github.com/tpoechtrager/osxcross/ |
You will also need the macOS SDK (see osxcross documentation) |
|
Windows |
x86_64-w64-mingw32-gcc |
On macOS: brew.sh/ On Linux: use your package manager |
macOS: install mingw-w64 package Linux: package names vary |
|
Linux/BSD |
gcc-linux |
On macOS: brew.sh/ On Windows: cygwin.com/install.html |
macOS: Install FiloSottile/musl-cross/musl-cross Windows: Install gcc-linux package |
Installing cross-compilation tools can be complicated—be sure to read the documentation on each download page and check your environment configuration after installing.
Full details of how to install and set up each of these compilers can be found in Appendix 2, Cross-Compiler Setup.
