Cross Compiling Implants

NOTE: Any platform can cross-compile a standalone executable to any other platform out of the box, you only need cross-compilers when using --format shared or --format shellcode.

From Linux to MacOS/Windows

For Windows, install mingw from your local package manager:

sudo apt install mingw-w64

For MacOS, we recommend using https://github.com/tpoechtrager/osxcross by default Sliver will look in /opt/osxcross but you can override this via environment variables.

Sliver automatically looks in the default paths for these cross compilers, once installed simply use the generate command with the desired --os and --arch, check ~/.sliver/logs/sliver.log for build errors. You can override any cross compiler location via the appropriate environment variables.

From MacOS to Linux/Windows

For Windows, install mingw from brew:

brew install mingw-w64

For Linux, we recommend musl-cross to target 64-bit Linux, which can be installed via brew:

brew install FiloSottile/musl-cross/musl-cross
brew install mingw-w64

I'm not aware of any good options to target 32-bit Linux from MacOS. Sliver automatically looks in the default paths for these cross compilers, once installed simply use the generate command with the desired --os and --arch, check ~/.sliver/logs/sliver.log for build errors. You can override any cross compiler location via the appropriate environment variables.

From Windows to MacOS/Linux

Good luck.
