Cross Compile

Currently supported targets:

Tier 1:

These builds are fully automated using Drone CI. Guaranteed to be fully reproducible.

• Linux (arm/x86)
• Windows 8+ (32 and 64 bit x86)

Tier 2:

These targets have no build automation available, but do not require patches to build or run.

• Mac OSX (> 10.10)
• Android (arm/x86)
• Apple IOS
• Linux PPC64 (little endian)
• FreeBSD (amd64)

Tier 3:

These targets are somewhat obscure or possibly obsolete, and may require some patching to fix target specific issues.

• Big Endian Linux
• NetBSD
• OpenBSD
• Windows pre-8 (while this is technically possible, the requirement for cryptographically reproducible builds precludes it.)
• UNIX v5 (x86 AMD64)

Unsupported (feel free to support this yourself)

we are completely unable to test these targets at all, proceed at your own risk

• AIX
• zOS

For Windows

To cross compile for windows on non windows platforms run:

$ make windows

For Other Linux

deps

this setup assumes ubuntu

first you need to cross compile and install libuv:

$ git clone https://github.com/libuv/libuv
$ mkdir -p build && cd build
$ export TOOLCHAIN=arm-linux-gnueabihf # or whatever your compiler is
$ cmake -DCMAKE_C_COMPILER=$(TOOLCHAIN)-gcc-8 -DCMAKE_INSTALL_PREFIX=/usr/$(TOOLCHAIN)
$ make
$ sudo make install

build

To cross compile on linux for another archietecture:

for rpi 3

$ make CROSS=ON TOOLCHAIN=contrib/armhf.toolchain.cmake

for ppc64le

$ make CROSS=ON TOOLCHAIN=contrib/ppc64le.toolchain.cmake
