MIPS Builds

OpenWrt An attempt is underway to port PortFusion to the MIPS CPU architecture. It is hoped to enable running PortFusion on OpenWrt routers and other embedded devices.

First target device is TL-WR1043ND, which is a big-endian MIPS architecture as shown on https://dev.openwrt.org/wiki/platforms.

Both big and little endian binaries are being built.

To check endiannes of your Linux:

$ echo -n I | hexdump -o | awk '{ print substr($2,6,1); exit}'
# 0 = big-endian
# 1 = little-endian

Build 1.2.1

Notes with QEMU

  • cabal update seems to hang but eventually finishes
  • no Haskell librararies are needed except what ships with haskell-platform
  • compilation takes around 30.0 (minutes.seconds)
  • linking takes around 2.0 (minutes.seconds)
  • resulting binary is stripped, its size is 8 MB
  • static linking does not work; so libgmp.so.10 is needed on target devices:
  • static linking does not work; binares require (e)glibc and not work with uclibc
